Of Composite Shapes P5

1 answer:

8 0

It is 114, because you subtract 6 from 15. So, the bigger thing is 90, add the smaller one onto it, 6 times 4 equals 24, 90+24=114.

The diameter of a circle is 8 inches. What is the area?

Serggg [28]

A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2

You go to a restaurant and your bill is $8.00. If you leave a 15% tip, How much did u spend all together at the restaurant?

g100num [7]

Find 15% of $8
Simply do this by multiplying 0.15 and 8
0.15 * 8 = 1.2
This means you left a $1.20 tip on top of your original $8
$8 + $1.20 = $9.20

Find the value of x if (1.1)^x=100

iragen [17]

Answer:

x ≈ 48.3177

Step-by-step explanation:

This is what logarithms are for (among other things).

log(1.1^x) = log(100)

x·log(1.1) = 2

x = 2/log(1.1) ≈ 48.3177

In a multiple regression model involving 44 observations, the following estimated regression equation was obtained. Ŷ = 29 + 18x

icang [17]

Answer: D. .400

Step-by-step explanation:

Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

$\hat{Y}= 29 + 18x_1 + 43x_2 + 87x_3$

For this model,

Regression sum of squares =SSR = 600

and Sum of squares due to error =SSE = 400.

Total sum of squares = SST= SSR+SSE

SST= 600+400=1000

The multiple coefficient of determination is given by :-

$R^2=1-\dfrac{SSR}{SST}$

Substitute values , we get

$R^2=1-\dfrac{600}{1000}$

$R^2=1-0.600=0.400$

Thus, the multiple coefficient of determination for the above model is $R^2=0.400$

Hence, the correct answer is D. .400.
