find the values of x and y?
Answer:x=20 y=70
Step-by-step explanation:
Answer:
x=20, y=70
Step-by-step explanation:
∠40°+∠adjacent to it =180°
∠adjacent= 180-40=140°
we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well
because sum of angles in a triangle has to be 180,
140 +x+x=180 so x=20°
from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70
A consumer magazine wants to compare the lifetimes of ballpoint pens of three different types. The magazine takes a random sample of pens of each type and conduct an ANOVA test. After the calculation, the F statistic is 1.62 and the p-value is 0.26. What is a correct decision at significance level of 0.1?
Answer: Fail to reject H0
Step-by-step explanation:
Given that:
P value = 0.26
α = 0.1
The values of both p and α can be compared in other to make a decision on whether to reject or fail to reject the Null hypothesis
Decisions :
If the p value > α (fail to reject null)
If p value < α ( Reject null)
In the scenario above :
0.26 > 0.1 ; p value > α
Since the p value is greater than alpha ; we fail to reject the Null

Find the measure of angle 1
Answer:
∠1 = 116
Step-by-step explanation:
Find the inner angle first, the inner angle will be represented with x, also a triangle is 180 degrees, so:
57 + 59 + x = 180
116 + x = 180
subtract 116 from both sides
x = 64
So now u have the inner angle, and a straight line is also 180 degrees, so:
64 + ∠1 = 180
subtract 64 from both sides
∠1 = 116

65% of 80 82% of 50 170% of 30
The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)
Explanation:
The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.
1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:
80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know
2. 82% of 50 - Repeat the same process
50 / 100 = 0.5 x 82 = 41
3. 170% of 30
30 / 100 = 0.3 x 170 = 51
4. Finally organize the values
82% of 50 (41)
170% of 30 (51)
65% of 80 (52)
Based on the information given about the percentages ,the ordering will be 82% of 50, 170% of 30, and 65% of 80.
Percentages.It should be noted that 82% of 50 will be:
= 82% × 50
= 41
170% of 30 will be:
= 1.7 × 30
= 51
65% of 80 will be:
= 65% × 80
= 0.65 × 80
= 52

What is the slope-intercept equation of the line that is perpendicular to y-4=-2/3(x-6) and that passes through (-2, -2)?
Answer:
The slope-intercept equation is:
[tex]y=\frac{3}{2}x+1[/tex]
Step-by-step explanation:
Given the equation
[tex]y-4=-\frac{2}{3}\left(x-6\right)[/tex]
comparing it with the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
so the slope of the line is -2/3.As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 3/2
The point-slope form of the equation of the perpendicular line that goes through (-2, -2) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-2\right)=\frac{3}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]
writing the line equation in the slope-intercept form
[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=\frac{3}{2}\left(x+2\right)-2[/tex]
[tex]y=\frac{3}{2}x+1[/tex]
Thus, the slope-intercept equation is:
[tex]y=\frac{3}{2}x+1[/tex]
Here,
As the slope-intercept form is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so
[tex]y=\frac{3}{2}x+1[/tex]
m=3/2
b = y-intercept = 1
Therefore, the slope-intercept equation is:
[tex]y=\frac{3}{2}x+1[/tex]

Store A sells 3 t-shirts for $25. Store B sells the same t-shirts: 5 for $40. Which store has the better deal?
Show your work supporting your answer.
Answer:
Store B
Step-by-step explanation:
To figure out which store has the better deal, we need to figure out the price per unit. We can do this by dividing the price by the number of the shirts. Store A sells their t-shirts for 8.33 or 8 1/3 dollars per shirt, while Store B sells their shirts for 8 dollars a shirt. 8 < 8 1/3, therefore Store B has the better deal.
Answer:
B.
Step-by-step explanation:
If you do 3/25=5/x. You would get $41.6. Another way to show it is to divide 25/3 and 40/5, which would give us $8.3 and $8.

Step-by-step explanation:
Hey there!
We know that the slope intercept is; y = mx+b.
Where "m" represents the slope. And "b" represents the y-intercept.
Example:
If the question is as; y = 3x +8
Then your slope of the slope intercept form is "3" where as "8" is y-intercept.
So, the variable"m" represents the slope.

Part A
Based on the graph, how many zeros does the polynomial function, f(x) = -x^4 - 3x^3 + 6x^2 + 8x have?
Part B
What are the zeroes of the above polynomial function?
A. -4,0,2,3
B. 0, 2 only
C. -4,-1, 0, 2
D. -4, 2 only
Answer:
Part A: There are 4 zeros of the polynomial function f(x)
Part B: The zeroes of the polynomial function f(x) are -4, -1, 0, 2 ⇒ C
Step-by-step explanation:
The zeroes of a function are the x-coordinates of the point of intersection between the graph of the function and the x-axis (x-intercepts) which means values of x at y = 0
Part A:
In the given graph
∵ The graph of the function f(x) = -[tex]x^{4}[/tex] - 3x³ + 6x² + 8x intersects the x-axis
at 4 points
→ That means there are 4 values of x have y = 0
∴ The number of zeroes of the function is 4
∴ There are 4 zeros of the polynomial function f(x)
Part B:
∵ The graph intersects the x-axis at points (-4, 0), (-1, 0), (0, 0), (2, 0)
→ That means the values of x at y = 0 are -4, -1, 0, 2
∴ f(x) = 0 at x = -4, -1, 0, 2
∴ The zeroes of the polynomial function f(x) are -4, -1, 0, 2
