Answer:

129

Step-by-step explanation:

8^2 + 9 (12/3 x 2) -7 Parentheses first 12 : 3 is the same as 12/3

8^2 + 9 (4x2)-7 Parentheses:

8^2 + 9 (8) - 7 Exponent 8 x 8:

64 + 9(8) - 7 Multiply:

64 + 72- 7 Add :

136 - 7 Subtract:

129

The answer is 129.

Hope this helps :)

Which phrase describes a nonlinear function?

Lorico [155]

The only non-linear equation from your choices is the area of a circle as it is:

A=πr^2 and if you take the derivative of A you have:

dA/dr=2πr

So the rate of change changes as r changes, it is not constant thus the function has acceleration, so velocity changes.

This is in contrast to any linear equation which is of the form:

y=mx+b now taking the derivative you see that:

dy/dx=m, now m is a constant value, which means that there is no acceleration and the velocity remains constant.

In a population, 11% of people are left handed. In a simple random sample of 160 people selected from this population, the propo

castortr0y [4]

Answer:

The claimed proportion (population) is

$p=0.11$

The sample proportion (p-hat) is

$\hat{p}=0.10$

Step-by-step explanation:

In the population, we have the parameter p that is 11%.

$p=0.11$

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

$\hat{p}=0.10$

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.
