Answer:

D. 154

Step-by-step explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154

What is the mean absolute deviation of her math scores?<br> 5.4<br> 6.4<br> 7.8.<br> o<br> 8.8
lara [203]

Answer:

The mean absolute deviation (MAD) of her Math scores would be 1.2.

Step-by-step explanation:

Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1

7.1 - 5.4 = 1.7

7.1 - 6.4 = 0.7

7.1 - 7.8 = 0.7

7.1 - 8.8 = 1.7

Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2

hope this helps :)

The Tigers lost 15% of the 60 games that they played this season. How many games did they win?
ludmilkaskok [199]
The first step, would be to make the percent a fraction. 15%=15/100.

So, if they played 60 games, and you want to find how many they lost, you would write x/60, when x=games lost.

15     x
___=___
100   60

Simplify the fraction on the left. Divide the numerator (top) and the denominator (bottom) by 5, leaving you with 3/20.

3/20=x/60

Make the denominators (bottom) similar

9/60=x/60

x=9

Based on the graph, what is the initial value of the linear relationship?
yuradex [85]

Answer:

The initial value of the linear relationship is y=-2

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The initial value is the value of the linear function when the value of x is equal to zero

therefore

The initial value is the y-coordinate of the y-intercept of the linear function

Observing the graph

The y-intercept is the point (0,-2)

so

For x=0

The value of y is equal to y=-2
