Given that the length of one leg is 6 and the angle is 40°

The hypotenuse is x.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trigonometric ratio.

Thus, we have;

$cos \ \theta=\frac{adj}{hyp}$

Substituting the values, we get;

$cos \ 45^{\circ}=\frac{6}{x}$

Simplifying, we have;

$x=\frac{6}{cos \ 45^{\circ}}$

$x=\frac{6}{0.766}$

Dividing, we get;

$x\approx7.83$

Therefore, the value of x is 7.83(app.)

Hence, Option A is the correct answer.

The following data points represent the number of children in each household on Maple Street. \qquad 0, 1, 2, 1, 20,1,2,1,20, co

zaharov [31]

Answer:

The mean number of the children is 1.2

<em></em>

Step-by-step explanation:

Given

Children: 0, 1, 2, 1, 2

Required

Determine the Mean number

The mean of a set is calculated as follows;

$Mean = \frac{\sum x}{n}$

Where x is the given set and n is the number of sets

In this case, n = 5 children

Hence;

$Mean = \frac{0 + 1 + 2 + 1 + 2}{5}$

$Mean = \frac{6}{5}$

$Mean = 1.2$

<em>Hence, the mean number of the children is 1.2</em>
