noname [10]

The following histogram shows the relative frequencies of the height recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches

(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work

Answer:

0.22268

Step-by-step explanation:

z-score is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work

At least means equal to or greater than 67 inches

z = 67 - 64.97/2.66

z = 0.76316

P-value from Z-Table:

P(x<67) = 0.77732

P(x>67) = 1 - P(x<67) = 0.22268

The probability that the selected woman will have a height of at least 67 inches is 0.22268

Elliott is standing at the top of a store escalator that leads to the ground floor below. the angle of depression from the top o
a_sh-v [17]

The top of the escalator exists 9 feet far from the ground floor.

<h3>How to estimate how far is the top of the escalator from the ground floor? </h3>

Let h denote the distance between the top of the escalator from the ground floor.

We have existed given that the angle of depression from the top of the escalator to the floor stands 36.84°, and the escalator exists 15 feet long.

The side h exists opposite side and 15 feet side exists hypotenuse of a right triangle.

$&\sin =\frac{\text { Opposite }}{\text { Hypotenuse }} \\

$&\sin \left(36.84^{\circ}\right)=\frac{h}{15} \\

$&\sin \left(36.84^{\circ}\right) * 15=\frac{h}{15} * 15 \\

$&0.599582468446 * 15=h \\

8.993737 = h

$&h \approx 9

Therefore, the top of the escalator exists 9 feet far from the ground floor.
