The probability of event A is 0.42, and the probability of event B is 0.39. If A and B are independent events, what is P(A and B)?
Answer:
0.1638
Step-by-step explanation:
P(A and B) or simply the probability of both events happening is the product of their individual probabilities.
P(A and B)= (0.42×0.39)= 0.1638

Answer:
8 m is the answer.
Step-by-step explanation:
a = ?
b (Brennan and Hannah) = 6 m
c (Jayce and Hannah) = 10 m
According to the Pythagoras theorem,
a² + b² = c²
a² + 6² = 10²
a² + 36 = 100
a² = 100 - 36
a² = 64
a = 8 m
∴ Jayce and Brennan are 8 m apart.
what is the area of the triangle? no links just the answer plz.
Answer:
A = 25
Step-by-step explanation:
Base = |-2-(-7)| = |-2+7| = 5
equation of the line that includes the base
x = 6 (because it is parallel to y axis)
the height passes to the point (-4,-4) and must be perpendicular to the base
the equation of the line of the base hasn’t the slope expressed, so the line of the height has a slope equal to 0
so the equation of the line is y= -4
the point (6,-4) is where the two lines intercept and it is the point where the height hit the base
height = |-4-6| = 10
A = (base x height)/2 = (5x10)/2 = 25

The perimeter of an isosceles triangle is 45 feet. The length of the shortest side is 11 feet. Find the length of the other two sides (in feet)
9514 1404 393
Answer:
17 feet
Step-by-step explanation:
The sum of the three side lengths is the perimeter.
s + s + 11 = 45
2s = 34 . . . . . . subtract 11
s = 17 . . . . . . . . divide by 2
Each of the other two sides is 17 feet.

Step-by-step explanation:
Joseph drove to his grandmother's house which is 279 miles away in 4.5 hours. If he continues at the same speed, approximately how long will it take him to drive 325 miles?
Answer:
5.24 hours
Step-by-step explanation:
I like to set these up as ratios.
279 miles/4.5 hours = 325 miles/ x hours
Then cross multiply
279x = 4.5 x 325
279x = 1462.5
divide both sides by 279
x = 5.24 hours
You can also solve 279 miles/4.5 hours to get the miles per hour driven, then divide 325 by that number:
279/4.5 = 62mph
325/62 = 5.24
Do you think the answer is A, B, C, or D.

$410 is invested in an account earning 4.2% interest (APR), compound quarterly. Write a function showing the value of the account after t years, where the annual growth rate can be found from constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.
Which expression is equivalent to 5 (4x+3)-2
To simplify an expression means to write it in the simplest way possible. Ideally, there would be no parentheses and everything has been 'expanded'.
Solving the QuestionWe're given:
[tex]5 (4x+3)-2[/tex][tex]5 (4x+3)-2[/tex]
Open up the parentheses by multiplying each term by 5:
[tex]=5*4x+5*3-2\\=20x+15-2\\=20x+13[/tex]
Answer[tex]20x+13[/tex]

Find the value of x in each figure
Answer:
Value of variable 'x' is 18.
Step-by-step explanation:
From the picture attached,
In right triangle XYZ,
m(∠YXZ) = (3x + 11)°
m(∠XYZ) = 90°
m(∠XZY) = 25°
By applying triangle sum theorem in the given triangle,
m(∠YXZ) + m(XZY) + m(∠XYZ) = 180°
(3x + 11)° + (25)° + (90)° = 180°
3x + 126 = 180
3x = 54
x = 18
Therefore, value of variable 'x' is 18.
Kate asked her friend what her favorite class at school is  how could she changed her questioning so that she can collect statistical data
Answer:
If Kate is trying to ask multiple people, Making a bar graph would be smart in order to know how much people liked what.
Step-by-step explanation:
Kate could ask all of the sixth grade students what their favorite class is.
What is a Statistical Data?Statistical data is defined as the data which are collected and interpreted in statistics.
These data are the information about something.
Given that,
Kate asked her friend what her favorite class at school is.
In order for her to collect statistical data, there must be more data related to the same question.
Then she can interpret the data with a conclusion.
So, she has to ask more people the same question that she asked with her friend.
So she could ask all of the sixth grade students what their favorite class is.
Hence the question can be changed as Kate could ask all of the sixth grade students what their favorite class is.

How do I solve for d(real answers only please)
9514 1404 393
Answer:
multiply by (d/cos(36°))
Step-by-step explanation:
As with any division problem, the equation remains true if you swap the divisor and the quotient (short answer).
cos(36°) = 16/d
d = 16/cos(36°) = 16/0.8090169943749475 ≈ 19.77708763999635
d ≈ 19.78
__
Here is the longer answer, with respects to the properties of equality. The multiplication and division properties of equality tell you equality only holds if the same operation is performed to both sides of the equal sign. So, when we say "multiply by __", we mean that operation to be performed on boths sides of the equation.
[tex]\cos{(36^{\circ})}=\dfrac{16}{d}\qquad\text{given}\\\\d\cdot\cos{(36^\circ)}=\dfrac{d\cdot 16}{d}=16\qquad\text{multiply by $d$}\\\\\dfrac{d\cdot\cos{(36^\circ)}}{\cos{(36^\circ)}}=\dfrac{16}{\cos{(36^\circ)}}\qquad\text{divide by $\cos{(36^\circ)}$}\\\\d=\dfrac{16}{\cos{(36^\circ)}}\qquad\text{simplify}[/tex]
__
The two operations, multiply by d and divide by cos(36°) can be combined into one: multiply by d/cos(36°). Once you realize this has the effect of the quotient (cos(36°)) and the divisor (d) trading places, you realize you don't need to take 3 steps to do what you can do in 1 step.

jack surveyed students at his school about whether they use computers or cell phones more. He found that of the 74 seventh-graders he surveyed, 53 said they used their cell phones more. In the 8th grade, 59 students used their cell phone more, compared to 38 who used their computer more. What number should be placed in the orange box below?
Answer:
Number of student of 7th grade using computer = 21
Total number of 8th grader student surveyed = 97
Step-by-step explanation:
The complete question is attached herewith
Solution
As we can see in the table
Total number of 7th grader student = 74
Out of these 74 student, 53 use cell phone
Hence, the number of student of 7th grade using computer = 74-53 = 21
Like wise, total number of 8th grader student surveyed = 59 +38 = 97

a.2x^2 and 4y^2
b.xy and yz
c.3x and and 7x
Answer:
C) 3x and 7x
Step-by-step explanation:
Both terms in C have the same variable in which you can combine the terms to make 1. The other ones don't.
Answer:
c. 3x and 7x
Step-by-step explanation:
We have three pairs of two terms and are asked to determine which option has "like terms."
Like terms are two numbers with variables that are the same.
With this information, we can determine which is and which isn't like terms.
a. 2x^2 and 4y^2 are incorrect because the variables within the number do not match, 2x^2 and 4y^2.
b. xy and yz are incorrect because the variables also do not match, xy and yz.
c. is correct because the variables within the two numbers are the same. 3x and 7x.

Answer:
Slope = -8/5
Step-by-step explanation:
Use the slope formula:
m = y2 - y1 / x2 - x1
Plug in the numbers from the ordered pairs given in the graph: (-1, 4) and (4, -4).
m = -4 - 4 / 4 - - 1
m = -8 / 5
m = -8/5
m = rise/run, meaning verticl units/horizontal units
Check your work by counting it out on the graph:
From the first black dot at (-1, 4), count 8 units down and then 5 units to the right. After counting, I ended at the second ordered pair at (4, -4) which means my slope is correct.
