Ok so the hint is very useful and it says to divide the figure into 2 rectangles so if we do so the shorter rectangle's side lengths would be 9, 5, 9, and 5 because that last little bit of length is equal to the longer rectangle and it is also exactly half of 10. so to find the area of a rectangle the formula is a=length* width. so if you were to plug it in it would be a= 9*5 and it equals 45 so you have the area of the first rectangle. Then to find the area of the second rectangle you would do the same thing as the first one. and you would end up with 75. Then just add those two numbers up to get the area

6)
2(9+10) = 38
2(5+6) = 22

P = 38+22=60 in

14)
9 x 10 = 90
6 x 5 = 30
A = 90+50 = 140 in^2

Solve the equation and show all work please show steps!!<br> m/9 - 17=21

masya89 [10]

Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.

The amounts of sugar (grams of sugar per gram of cereal) and calories (per gram of cereal) were recorded for a sample of 16 diff

tigry1 [53]

Answer:

The best predicted calorie count for a cereal with a measured sugar amount of 0.40 g is 3.864

Step-by-step explanation:

Consider the provided information.

he linear correlation coefficient is r= 0.765 and the regression equation is $\hat y= 3.46 + 1.01\times x$

The mean of the 16 amounts of sugar is 0.295 grams and the mean of the 16 calorie counts is 3.76.We need to find the best predicted calorie count for a cereal with a measured sugar amount of 0.40 g

Substitute x = 0.40 in the given equation.

$\hat y= 3.46 + 1.01\times 0.40$
