Answer:
the probability that a randomly selected South African man is taller than 72 inches is 0.2266
Step-by-step explanation:
The heights of South African men are Normally distributed with a mean of 69 inches and a standard deviation of 4 inches
population mean(m) = 69 inches
population standard deviation(s) = 4 inches
Therefore, the number of standard deviation above mean (z score) = (x - m)/s
In this case, x = 72 inches
z score = (72 - 69)/4 = 3/4 = 0.75
Probability that a randomly selected South African man is taller than 72 inches P(x>72) = 1 - P(x<72) = 1 - z(0.75) using the z table,
P(x>72) = 1 - 0.77337 = 0.2266
therefore, the probability that a randomly selected South African man is taller than 72 inches is 0.2266
Answer:
The pattern form is 8,15,34,71 which follows the rule 
Step-by-step explanation:
Given : Rule 
To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?
Solution :
Rule 
Put n=1,


Put n=2,


Put n=3,


Put n=4,


The pattern form is 8,15,34,71 which follows the rule 
Use same-length line segments to solve for x and y.
... PS = SR
... 4x +4 = 7x -17
... 21 = 3x . . . . . . . . . add 17-4x
... 7 = x . . . . . . . . . . . divide by 3
... PS = SR = 4·7+4 = 32
... PQ = QR
... 5y -31 = 2y +5
... 3y = 36 . . . . . . . . . add 31-2y
... y = 12 . . . . . . . . . . . divide by 3
... PQ = QR = 2·12 +5 = 29
... PT = TR = 6·7-2·12 = 18
Answer:
Greater than symbol.
2/3 > 2/4
Step-by-step explanation:
We have two fractions, 2/3 and 2/4
We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).
Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.
2/3 and 2/4
With 2/3 being greater than 2/4.
2/3 = 0.67
2/4 = 0.50
Succinctly, 2/3 > 2/4.
