Answer:

3/4

Step-by-step explanation:

1½ = 3/2

3/2 _ 3/4 =

\ \frac{3 \times 2}{2 \times 2}  -  \frac{3}{4}

\frac{6}{4}  -  \frac{3}{4}  =  \frac{6 -  3}{4}  =  \frac{3}{4}

The height of adult males on a given South Pacific Island is approximately normally distributed with mean 65 inches and standard
zvonat [6]

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

Answer: 300.

Step-by-step explanation: 225/(No denominator) = 75/100.

225 doesn't go in 75. So, 75/100 divided by 5 = 15/20.

I want to find what number you multiply from 15/20 to get 225/(No

denominator). So, I divide 225 by 15. = 15, so multiply 15 x 15 = 225, and

the denominator, 20 x 15= 300.

(Sorry if you don't understand, I don't really know how to explain things.)

But here's your answer!
