A particular group of men have heights with a mean of 174 cm and a standard deviation of 6 cm. Earl had a height of 192 cm. a. W
Sati [7]

Answer:

a) 18 cm

b) 18

c) 3

The Earl's height is unusual because the  z score does not lies in the given range of usual i.e -2 and 2

Step-by-step explanation:

Given:

Mean height, μ = 174 cm

Standard deviation = 6 cm

height of Earl, x = 192 cm

a) The positive difference between Earl height and the mean = x - μ

= 192 - 174 = 18 cm

b) standard deviations is 18

c) Now,

the z score is calculated as:

z=\frac{x-\mu}{\sigma}

or

z=\frac{192-174}{6}

or

z = 3

The Earl's height is unusual because the  z score does not lies in the given range of usual i.e -2 and 2

I need help to the attachment down below, first answer gets 5 stars and a thanks!
Gekata [30.6K]

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = \frac{base*height}{2}

52.5 = \frac{base*height}{2}

52.5 = \frac{base*7}{2}

52.5 * 2 = base × 7

105 = base × 7

base = 15

STatiana [176]

Answer:

y=69

Step-by-step explanation:

first step:when y=26 and x=21

c=y-x

c=26-21

c=5

second step: when y is unknown and x=64

To find y we simply add the value of c to x

y=x+c

y=64+5

y=69
