The heights of women aged 20 to 29 are approximately normal with mean 64 inches and standard deviation 2.7 inches. men the same
Artyom0805 [142]
<span>To find the z-scores, find the difference in the number of inches for each value from the mean and then divide that by the standard deviation. For women at 72 inches (6'), this would be (72-64) / 2.7, or a z-score of +2.963. For a male at 72 inches, this would be (72-69.3)/2.8, or +0.964. This shows that the woman at 6 feet tall is more rare in the distribution than a man at 6 feet tall.</span>

2/3×3/2=1
8×3/2=12
So 1 to 12

The value of y varies directly with x and y=12 when x=-6 find y when x=-4
FinnZ [79.3K]

Answer:

B)8

Step-by-step explanation:

That is the right answer because when y=12,  x=-6

12/-6 = -2

This means that x = y/-2

or y = x * -2

-4 * -2 = 8

Great Amusements Park has been raising its ticket prices every year, as shown in the table below
Fiesta28 [93]
1.)

Between year 0 and year 1, we went from $50 to $55.

$55/$50 = 1.1

The price increased by 10% from year 0 to year 1.

Between year 2 and year 1, we went from $55 to $60.50.

$60.50/$55 = 1.1

The price also increased by 10% from year 1 to year 2. If we investigate this for each year, we will see that the price increases consistently by 10% every year.

The sequence can be written as an = 50·(1.1)ⁿ

2.) To determine the price in year 6, we can use the sequence formula we established already.

a6 = 50·(1.1)⁶ = $88.58

The price of the tickets in year 6 will be $88.58.
