Step-by-step explanation:
<u>Step 1: Define
</u>
y = home runs
x = hits
[Best Line of Fit] y = 0.15x - 1.5
<em>We can use this to predict the average of the scatter plot.
</em>
home runs = y = 35
<u>Step 2: Solve for </u><em><u>x</u></em><u> hits</u>
-
Substitute [BLF]: 35 = 0.15x - 1.5
- Add 1.5 on both sides: 36.5 = 0.15x
- Divide 0.15 on both sides: 243.333 = x
- Rewrite: x = 243.333
Remember that this is a <em>prediction</em>. According to the best line of fit, we would need approximately ~243 to get 35 home runs.
This would be C. 60$
This is because if she got the bag for 50% off, 30 divided by 2 is 15$, 45 divided by 2 is 22.5, 60 divided by 2 is 30$ so option C. Would be your answer.
Answer:
Step-by-step explanation:
WY is the diameter.
WX and XY sum to 180° as half the circle.
<u>Central angle is equal to intercepted arc:</u>
- mXY = m∠XVY = 87°
- mWX = 180° - mXY = 180° - 87° = 93°
Correct choice is C
Given that AB has been dilated by scale factor 3 to form A'B', and by laws of dilation, the image is congruent to the pre image. This implies that the image will not change in any way whatsoever apart from the size. Hence the slope will remain the same. That means the slope of A'B' will be 3
Answer:
1/27
Step-by-step explanation:
[(3^-5)(3^4)]^3
= [(3^(-5+4)]^3
= [3^-1]^3
= 3^-3
= 1/3^3
= 1/27
