The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of

bezimeni [28]

Answer:

C. The normal distribution can be used because the original population has a normal distribution.

Step-by-step explanation:

When the original population has a normal distribution, we can use the normal distribution to solve the exercise.

In this problem, we have that:

The original population are the adult females.

The problem states that:

The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of

7.8 cm.

So the correct answer is

C. The normal distribution can be used because the original population has a normal distribution.

Help me please!!!!!!

lara [203]

Answer:

a. $b=2$

b. $b = 2a$

c. $a = \frac{1}{2}b\\$

d. $b = 10$

Step-by-step explanation:

Gradient is just another similar term for slope l, $m$ , and it can be calculated by $m = \frac{y_2 -y_1}{x_2 -x_1}\\$ where $x_n$ and 1 $y_n$ is the $xy$ -coordinates of point $n$

We let $(0,0)$ be point $1$ and $(a,b)$ be point $2$ , we can then write the equation:

$m = \frac{b -0}{a -0}\\ m = \frac{b}{a}$ .

It also says that the points are with a gradient of $2$ so $m = 2$ . We can then write the equation:

$2 = \frac{b}{a}\\$

Finding $b$ If $a = 1$ :

$2 = \frac{b}{a} \\ 2 = \frac{b}{1} \\ 2 = b \\ b = 2$

Writing an expression for $b$ in terms of $a$ .

$2 = \frac{b}{a} \\ \frac{b}{a} = 2 \\ \frac{b}{a} \times a = 2 \times a \\ b = 2a$

Writing an expression for $a$ in terms of $b$

$2 = \frac{b}{a} \\ \frac{b}{a} = 2 \\ \frac{a}{b} = \frac{1}{2} \\ \frac{a}{b} \times b = \frac{1}{2} \times b \\ a = \frac{1}{2}b$

Finding $b$ if $a = 5$

$2 = \frac{b}{a} \\ 2 = \frac{b}{5} \\ \frac{b}{5} = 2 \\ \frac{b}{5} \times 5 = 2 \times 5 \\ b = 10$

This table gives a few (x,y) pairs of a line in the coordinate plane

blagie [28]

Answer:

The x-intercept of the line is the point (12,0)

Step-by-step explanation:

step 1

Find the slope of the lime

Take the points

(22,36) and (32,72)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{72-36}{32-22}$

$m=\frac{36}{10}$

$m=3.6$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=3.6$

$point (22,36)$

substitute

$y-36=3.6(x-22)$

step 3

Find the x-intercept

we know that

The x-intercept of a line is the value of x when the value of y is equal to zero

For y=0

substitute in the equation and solve for x

$0-36=3.6(x-22)$

$0-36=3.6x-79.2$

$3.6x=79.2-36$

$3.6x=43.2$

$x=12$

therefore

The x-intercept of the line is the point (12,0)
