PLS HELPLO Find the change in x for ordered pairs (6,-3) and (5, 1) *

Ghella [55]

Answer:

The change in x = Δx = -1

Step-by-step explanation:

Given the ordered pairs

(6, -3)

(5, 1)

Here,

x₁ = 6

x₂ = 5

y₁ = -3

y₂ = 1

Change in x can be calculated by subtracting the value of x₁ = 6 from x₂ = 5.

Change in x = Δx = x₂ - x₁ = 5 - 6 = -1

Thus, the change in x = Δx = -1

A survey found that women's heights are normally distributed with mean 63.2 in. and standard deviation 2.4 in. The survey also

Effectus [21]

Answer: 99.51%

Step-by-step explanation:

Given : A survey found that women's heights are normally distributed.

Population mean : $\mu =63.2 \text{ inches}$

Standard deviation: $\sigma= 2.4\text{ inches}$

Minimum height = 4ft. 9 in.= $4\times12+9\text{ in.}=57\text{ in.}$

Maximum height = 6ft. 2 in.= $6\times12+2\text{ in.}=74\text{ in.}$

Let x be the random variable that represent the women's height.

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x=57, we have

$z=\dfrac{57-63.2}{2.4}\approx-2.58$

For x=74, we have

$z=\dfrac{74-63.2}{2.4}\approx4.5$

Now, by using the standard normal distribution table, we have

The probability of women meeting the height requirement :-

$P(-2.58$

Hence, the percentage of women meeting the height requirement = 99.51%
