Step-by-step explanation:
the angle south-east of x is hard to read.
I assume this is 86 (but could be also 96).
remember, the sum of all angles in a triangle is always 180°.
and the intersection angles between 2 lines are the same in both sides of the lines. the only difference between above and below angles is that they are left-right mirrored.
so,
180 = x + 22 + 86
x = 180 - 22 - 86 = 72°
x and y are intersection angles of 2 lines and are therefore equal (due to the left-right mirroring).
y = x = 72°
180 = w + 33 + 72
w = 180 - 33 - 72 = 75°
remember also that the sum of all angles around a single point on one side of a line is always 180°, because the line can be seen as diameter of a circle with the point being the circle center. and the degrees of a half-circle are 180°.
180 = angle1 + unnamed angle = angle1 + 85
angle1 = 180 - 85 = 95°
180 = angle2 + angle3 + unnamed angle =
= 42 + angle3 + 85
angle3 = 180 - 42 - 85 = 53°
for the third question we don't see a picture of the situation. I assume this is a circle with O being the center of the circle, and Q, N, P are points on the circle arc.
it is not clear, if the angle QOP is part of the angle QON, or if they are separate segments of the circle.
if the angle QOP is part of the angle QON, then the angle PON = 142 - 46 = 96°
if the angle QOP is separate from the angle QON, then the angle PON = 360 - 142 - 46 = 172°
you are dealt five cards from a thoroughly shfuffeld standard deck of cards. what is the probability that you get a full hosue.
The probability of drawing 3 aces and 2 kings is 9.23×[tex]10^{-6}[/tex] and the probability of a “full house” is 0.00144.
5 cards are drawn from a standard deck of 52 cards.
a) Probability that we draw 3 aces and 2 kings
Number of cards = 52
No of aces = 4
No of kings = 4
Number of cards drawn = 5
So, the probability becomes,
Text, letter
Description automatically generated with medium confidence
[tex]4C_{3}4C_{2}[/tex]/[tex]52C_{5}[/tex]
On simplification,
= 24 / 2598960

So the probability of drawing 3 aces and 2 kings is 9.23 × [tex]10^{-6}[/tex]
b) a “full house” (3 cards of one kind and 2 cards of another kind)
Since there are 13 sets of each type, we have to select any 2 kinds of it.
The probability becomes
(2×[tex]13 C_{2}[/tex]×[tex]4C_{3}[/tex][tex]4C_{2}[/tex])/[tex]52C_{5}[/tex]
On simplification,
= 3744 / 2598960

So, The probability of a “full house” is 0.00144.
Therefore, the probability of drawing 3 aces and 2 kings is
9.23×[tex]10^{-6}[/tex] and the probability of a “full house” is 0.00144.
The possibility is the department of arithmetic concerning numerical descriptions of ways in all likelihood an event is to arise, or how in all likelihood it's miles that a proposition is authentic. The opportunity of an occasion varies between zero and 1, wherein, more, or less speaks to me, 0 suggests the impossibility of the event and 1 shows reality. The better the probability of an event, the much more likely it's far that the event will arise.
An easy example is the tossing of a fair (unbiased) coin. for the reason that coin is fair, the 2 effects ("heads" and "tails") are each equally probable; the opportunity of "heads" equals the possibility of "tails"; and considering no other outcomes are viable, the opportunity of either "heads" or "tails" is half off (which can additionally be written as 0.5 or 50%).

Find the lengths of the hypotenuses (x) of the triangle whose legs are given
1) 12cm,16cm
Answer:
Step-by-step explanation:
The hypotenuses(x) of the triangle whose legs are 12 cm and 16 cm is 20 cm.
As we know that in a right angled triangle there are base, perpendicular and hypotenuse. a hypotenuse is the longest side of a right triangle. In other words, the side opposite to the right angle is called the hypotenuse.
Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
By Pythagoras theorem, hypotenuse (x) = √(a² + b²)
= √(16² + 12²)
= 20 cm
Line k has a slope of 1/3. Line j is perpendicular to line k and passes through the point (1,4). Create an equation for line j.

a boat moves 8 kilometers upstream in the same amount of time it moves 20 kilometers downstream. if the rate of the current is 5 kilometers per hour, find the rate of the boat in still water.
if the rate of the current is 5 kilometers per hour, The rate of the boat in still water is 15 km/h.
The rate of the boat in still water is the rate of the boat when the current is not affecting its motion, so we can calculate the rate of the boat in still water by subtracting the rate of the current from the rate of the boat while moving downstream and adding the rate of the current to the rate of the boat while moving upstream. In this case, the rate of the boat while moving upstream is 8 km/h, and the rate of the boat while moving downstream is 20 km/h. Since the rate of the current is 5 km/h, we can subtract 5 km/h from 20 km/h to get the rate of the boat in still water, which is 15 km/h.
Rate of boat in still water = Rate of boat while moving downstream - Rate of current + Rate of boat while moving upstream
= 20 km/h - 5 km/h + 8 km/h
= 15 km/h

5. Sima invests some money in an account that earns a fixed rate of interest
compounded annually. The amounts of the investment at the end of the first
three years are shown below
a) Determine the annual rate of compound interest earned.
b) How much did Sima invest?
Year. Total amount
1. $4240.00
2. $4494.40
3 $4764.06
Answer:
Step-by-step explanation: To solve this problem, we can use the following formula for compound interest:
A = P * (1 + r/n)^(n*t)
Where:
A is the total amount at the end of the period
P is the principal (initial investment)
r is the annual interest rate
n is the number of times the interest is compounded per year
t is the number of years
We can rearrange this formula to solve for r:
r = n * ((A/P)^(1/n*t) - 1)
We can plug in the values for A, P, and t for each year to solve for the annual interest rate:
Year 1:
r = n * ((4240.00/P)^(1/n*1) - 1)
r = 1 * ((4240.00/P)^(1/1) - 1)
r = (4240.00/P) - 1
r = 4240.00/P - 1
r = 4240.00 - P/P
r = 4240.00 - 1
r = 0.08
Year 2:
r = n * ((4494.40/P)^(1/n*2) - 1)
r = 1 * ((4494.40/P)^(1/2) - 1)
r = (4494.40/P)^(1/2) - 1
r = 4494.40/P - 1
r = 4494.40 - P/P
r = 4494.40 - 1
r = 0.08
Year 3:
r = n * ((4764.06/P)^(1/n*3) - 1)
r = 1 * ((4764.06/P)^(1/3) - 1)
r = (4764.06/P)^(1/3) - 1
r = 4764.06/P - 1
r = 4764.06 - P/P
r = 4764.06 - 1
r = 0.08
Since the annual interest rate is consistent at 0.08 for all three years, we can conclude that this is the annual rate of compound interest earned.
To solve for the principal, we can use the formula for compound interest again, this time solving for P:
P = A / (1 + r/n)^(n*t)
Plugging in the values for A, r, and t for each year, we get:
Year 1:
P = 4240.00 / (1 + 0.08/1)^(1*1)
P = 4240.00 / 1.08
P = 3925.93
Year 2:
P = 4494.40 / (1 + 0.08/1)^(1*2)
P = 4494.40 / 1.16
P = 3925.93
Year 3:
P = 4764.06 / (1 + 0.08/1)^(1*3)
P = 4764.06 / 1.24
P = 3925.93
Since the principal is consistent at $3925.93 for all three years, we can conclude that this is the amount Sima invested.

Line m passes through points (7, 6) and (5, 13). Line n is perpendicular to m. What is the
slope of line n?
Answer:
-3.5
Step-by-step explanation:
To find the slope of line n, we need to find the slope of line m first. The slope of a line is calculated by dividing the difference in the y-coordinates of two points on the line by the difference in the x-coordinates of the same two points. In this case, we can use the two points (7, 6) and (5, 13) to calculate the slope of line m. The difference in the y-coordinates of these two points is 13 - 6 = 7, and the difference in the x-coordinates is 5 - 7 = -2. Dividing the difference in the y-coordinates by the difference in the x-coordinates yields 7 / -2 = -3.5.
A line is perpendicular to another line if the product of their slopes is -1. Since the slope of line m is -3.5, the slope of line n, which is perpendicular to line m, is -1 / -3.5 = 1/3.5 = <<-1/-3.5=1/3.5>>1/3.5.
Answer:
Slope of a line equation.
Formula for slope of line n is m= rise/run. y2-y1/x2-x1
(7,6) is (x1, y1) and (5,13) is (x2,y2). Simply plug these values in to the equation and solve.
Step-by-step explanation:

7/-2 = - 7/2
- 7/2 = -3.5.
Perpendicular just means that the 1. answer changes sign (pos/neg). This answer is negative, so it becomes a positive. 2. the denominator number switches places with the numerator number. so 7/2 becomes 2/7. Decimal version is 3.5/1 becomes 1/3.5

An object is moving at a speed of 6 inches every 4 to 5 days. express the speed in yards per year. round your answer to the nearest 10th
Answer:
The speed in yards per year is 60.8.
Step-by-step explanation:
To convert the speed from inches per day to yards per year, we need to first convert the speed to inches per year and then convert the units to yards per year.
First, we can convert the speed to inches per year by multiplying the speed by the number of days in a year:
Speed (inches/day) * Days per year = Speed (inches/year)
6 inches/day * 365 days/year = 2190 inches/year
Next, we can convert the units to yards per year by dividing the speed in inches per year by the number of inches per yard:
Speed (inches/year) / Inches per yard = Speed (yards/year)
2190 inches/year / 36 inches/yard = 60.8 yards/year
Rounding to the nearest 10th, we have:
60.8 yards/year ≈ 60.8 yards/year
Therefore, the speed in yards per year is 60.8.

- Make a decision using the p-value approach
We can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.
Two-Hypotheses:
H0: The mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is not significantly less than the overall mean waiting time of 13 minutes.
Ha: The mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.
Test Statistic: t = (11 - 13) / (8/√50) = -2.5 and the Critical Value Approach is: The critical value for a one-tailed test at alpha = 0.05 is 1.645. Since the test statistic (-2.5) is less than the critical value (1.645), we can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes, and the P-Value Approach: The p-value for the one-tailed test is 0.0062. Since this p-value is less than alpha = 0.05, we can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.

Consider continuous functions f and g. then complete the statement. function g is the sum of 2 and the cube root of the sum of three times x and 1. select the correct answer from each drop-down. the x-intercept of function f is the x-intercept of function g.
The x-intercept of the function f is greater than the x-intercept of function g is the correct statement.
What is x-intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
How to find x-intercept?Setting y = 0 will provide the x-value at which the line crosses the x-axis, allowing us to find the x-intercept
Function g(x) is defined as:
g(x)=2+[tex]\sqrt[3]{3x+1}[/tex]
and f(x)=0
To find x-intercept let g(x)=0
So
2+[tex]\sqrt[3]{3x+1}[/tex]=0
[tex]\sqrt[3]{3x+1}[/tex]=-2
Taking cube on both sides we get
3x+1= -8
3x=-9
x=-3
The x-intercept of g(x) + -3, which is less than the x-intercept of function f(x), hence, the correct statement is:
The x-intercept of the function f is greater than the x-intercept of function g.

Inez heard that a a general rule, he hould pend no more than 30% of her take-home pay on rent. If Inez' take-home pay i $46. 800 per year, what i the maximum amount per month that he hould pent or rent?
The maximum amount per month that Inez would spent on rent is $1170 knowing that he could spend no more than 30% of the take home pay.
Here Inez heard that a a general rule, he should pend no more than 30% of her take-home pay on rent. If Inez' take-home pay i $46. 800 per year.
The term Take-home pay is the net amount of income received after the deduction of taxes, benefits, and voluntary contributions from a paycheck. It is the difference resulting from the subtraction of all deductions from gross income.
Pay = $46,800
Total allowed = 46,800 x 0.30
Total allowed = $14,040
Now since we know that there are 12 months in a year, we need to divide the Total allowed by 12 to find how much Inez can pay in rent per month.
14,040 / 12 = $1,170
Following the rule that he could not spend more than certain of the take home pay he should rent $1170.

what is the probablity that six consecutive integers will be chosen as the winning lottery numbers where each number chsoen is an integer between 1 and 40
The probability is 0.00000911843.
The number of terms is 40 because the number selected falls within the range of integers 1 through 40 (inclusive).
Thus; n = 40
The combination formula, which is; gives the probability that 6 integers (r = 6)—the number of possible outcomes—will be obtained without repetition.
C(n, r) = n!/((n - r)!(n - r)!)
C(40, 6) = 40!/(6!(40 - 6)!)
C(40,6) = 3838380

adam has collected the birth rates, gender, age, and total population numbers for akron, ohio. what population statistic could adam calculate with this information?
By the age of four, Adam knows that changing one's exterior characteristics does not change one's gender. Adam has "acquired" or "learned" gender constancy.
Which of the three stages of gender constancy are you?
A child's developing sense of the permanency of being a boy or a girl, which happens in stages: gender identification, gender stability, and gender consistency. Gender constancy is similar to Piaget's concept of physical property conservation in that gender constancy relates to the awareness that gender is an invariant human property that is stable through time and superficial changes in appearance. It starts at the age of six or seven, when a youngster realizes that gender remains consistent across settings (e.g. if a man puts on a dress he is still a man).

find it using angles
Step-by-step explanation:
Angle ABC is a straight angle.
Angles ABD and DBC are right angles.
Angles CBE and DBE are acute angles.
Angle ABE is an obtuse angle.
Angles
The sum of the three angles in any triangle is always 180°.
a + b + c = 180°
Knowing that the sum of the angles of triangle is 180° can help you to solve problems about triangles.
Angles
In this triangle, angle b is a right angle and angle c = 40°. What is the measure of angle a?
a + b + c = 180°
Since b is a right angle, b = 90°.
The problem states that c = 40°.
Therefore, a + 90° + 40° = 180°
a + 130° = 180°
a + 130° − 130° = 180° − 130°
a = 50°
Angle a measures 50°.
