Leona [35]

Answer:

The right answer is "0.70".

Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒ $P[(X$

By putting the values, we get

$=\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}$

$=\frac{(0.20+0.15)}{1-0.20-0.30}$

$=\frac{0.35}{0.5}$

$=0.70$

The formula for the surface area, S, of a cylinder, is S = 2tr2 + 2trh, where h is

kykrilka [37]

Answer:

H = 2 S = 50 A = 50.2

Step-by-step explanation:

A=2πrh+2πr2

S = 2tr2 + 2trh

S = 2 (t x r) + (h x 2t) x r Try out ^2 for Radius

S = 2t x r^2 + r x h x 2t Rearrange back and cross out for square^2

S = 6t x 4 + 6t x r x h Cross out for t

S = 6 x 4 + 6 x 2 x h Balance out...

S= 24 + 12 x 2 Find h = 2

S = 36 + 24

S= 50 sq2

A = 50. 2

R = 2

H = 2

Checker

Area = 6.28318530718 x 4 + 6.28318530718 x 2 x 2 = 50.27sq2

85% of the people survey thought the price of the car wash was reasonable. If 164 people thought the cost of the car wash was re

8090 [49]

192 people were survey

Step-by-step explanation:

The given is:

85% of the people survey thought the price of the car wash was reasonable
164 people thought the cost of the car wash was reasonable

We need to find how many people were survey

Assume that x people were survey

∵ There were x people survey

∵ 85% of them thought the price of the car wash was reasonable

∴ The number of the people who thought the price of the car wash

was reasonable = 85% × x

∵ 85% = $\frac{85}{100}$ = 0.85

∴ The number of the people who thought the price of the car wash

was reasonable = 0.85 x

∵ 164 people thought the cost of the car wash was reasonable

- Equate 0.85 x and 164

∴ 0.85 x = 164

- Divide both sides by 0.85

∴ x = 192.94

∵ x represents a number of people, then it must be integer

∴ The number of people were survey = 192

192 people were survey
