my answer is a bit different but kinda similar ig.

254.34in^2

Step-by-step explanation:

Radius = Diameter/2 18/2 = 9

Area of circle= pi(3.14) x r^2

A= (3.14) x 9^2

A= (3.14) x 81

Answer:

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a sample size larger than 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

So

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

Choose the equation that has solutions (5,7) and (8,13).

Alekssandra [29.7K]

<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

$(x_{1},y_{1})$ is called solution of a equation if $(x_{1},y_{1})$ satisfies the equation.

Consider the equation $y=2x-3$ ,

For point $(5,7)$ ,

$LHS=y=7$

$RHS=2x-3=2(5)-3=10-3=7$

So, $RHS=LHS$

The point $(5,7)$ satisfies the equation.

For point $(8,13)$ ,

$LHS=y=13$

$RHS=2x-3=2(8)-3=16-3=13$

So, $RHS=LHS$

The point $(8,13)$ satisfies the equation.

So,both the points satisfy the equation $y=2x-3$
