Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

$y = a(b)^x$

In which a is the value of y when x = 0.

In this question:

When $x = 0, y = 3$ . Thus, we have that a = 3.

Find the area of this triangle.

Katyanochek1 [597]

Answer:

120 ft²

Step-by-step explanation:

The formula to find the area of a triangle is :

Area = $\frac{1}{2}$ × base × height

Given that,

base ⇒ 30 ft

height ⇒ 8 ft

Let us solve it now.

Area = $\frac{1}{2}$ × base × height

Area = $\frac{1}{2}$ × 30 ft × 8 ft

Area = $\frac{1}{2}$ × 240 ft²

Area = 120 ft²

The number of siblings an individual has varies from student to student. The distribution of the number of siblings is strongly

ivanzaharov [21]

Answer:

(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
