Answer:
a) 0.59871
b) 0.22663
e) 0.95994
Step-by-step explanation:
The height of adult males on a given South Pacific Island is approximately normally distributed with mean 65 inches and standard deviation of 4 inches.
We solve using z score
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 65 inches
σ is the population standard deviation = 4 inches
a). Taller than 64 inches
This means x > 64
Hence,
64 - 65/4
=- 1/4 = -0.25
P-value from Z-Table:
P(x<64) = 0.40129
P(x>64) = 1 - P(x<64) = 0.59871
b.) shorter than 62 inches
Hence,
62 - 65/4
=- 3/4 =- 0.75
P-value from Z-Table:
P(x<62) = 0.22663
c.) between 64 inches and 68 inches
Hence,
for 64 inches
64 - 65/4
=- 1/4 = -0.25
P-value from Z-Table:
P(x = 64) = 0.40129
For 68 inches
Hence,
68 - 65/4
= 3/4= 0.75
P-value from Z-Table:
P(x = 68) = 0.77337
d.) between 58 and 68 inches
e.) taller than 58 inches
Hence,
58 - 65/4
= -6/4 = -1.5
P-value from Z-Table:
P(x<58) = 0.040059
P(x>58) = 1 - P(x<58) = 0.95994

Determine the niinimum and maximum value of the following trigonometric
function.
f(x) = 5 cos 3x – 3
9514 1404 393
Answer:
maximum: +2
minimum: -8
Step-by-step explanation:
The cosine has a minimum of -1 and a maximum of +1. Then the extremes of f(x) are ...
5(±1) -3 = -3±5 = +2, -8
The maximum of f(x) is +2; the minimum is -8.

Answer:
x = 622 (rounded to the nearest whole number value)
Step-by-step explanation:
=> Step 1: Solve for the base of top triangle;
Tan(39) = [tex]\frac{base1}{521}[/tex]
Tan(39) * 521 = base1
421.897 = base1
=> Step 2: Solve for the base of the bottom triangle;
Tan(21) = [tex]\frac{Base2}{521}[/tex]
Tan(21) * 521 = Base2
199.993 = Base2
=> Step 3: Finding x;
Base1 + Base2 = x
421.897 + 199.993 = x
621.89 or 622 = x

9514 1404 393
Answer:
042
Step-by-step explanation:
The first clue tells you the possibilities are ...
6__, _8_, or __2
The second clue eliminates 6__ and tells you the possibilities are ...
18_, _81, 1_2, 48_, _42
The third clue tells you two of the correct digits are 0 and 2, since 6 has already been eliminated by the first two clues. This only leaves 042.
042 is consistent with the last 2 clues.
The 3-digit key is 042.

What is the shape of this distribution?
A. Bimodal symmetric
B. Uniform
c. Unimodal symmetric
D. Bimodal skewed
E. Unimodal skewed
Answer:
Uniform
Step-by-step explanation:
We don't have any peaks in the histogram, so its neither unimodal or bimodal leaving only uniform as the answer.
The shape of this distribution, histogram is Unimodal skewed type. The correct option is E.
What is histogram?A histogram represents the graphical representation of the distribution of data. The histogram is indicated by using a set of rectangles adjacent to each other where each bar represent a kind of data. The histogram doesn't involve any gaps between the two successive bars.
The histogram would be classified into different types based on the frequency distribution of the data.
Based on the direction of the tail, the skewed distribution may be either right-skewed or left skewed.
Since skewed distribution is asymmetrical as a limit which is natural resists end results on one side.
Threfore, the correct option is E.

Is 72 Inches greater less or equal to 2 yd and why
Answer:
72 is equal to 2 yards.
Explanation:
There are 36 inches in one yard.
(another way to look at this is there are 3 feet in one yard, each feet is 12 inches. So, 12 multiplied by 3 is equal to 36 inches, or one yard)
Then, since in this question we are finding out in relation to 2 yards, add 36 inches + 36 inches, and that is equal to 72 inches.
72 and 72 are equal :)
