trapecia [35]

Answer: 2514.28\ cm^3

Step-by-step explanation:

Given

The height of the cylinder is h=8\ cm

Circumference of the base is 20\pi \ cm

suppose 'r' is the radius of the cylinder

\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm

The volume of a cylinder is V=\pi r^2h

\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3

Carly wants to add texting to her cell phone plan. She has two choices in texting packages. The TURKEY plan charges $.15 per tex
alina1380 [7]

TURKEY 0.15xy+20y

GOBBLE 0.20xy+0y

x is the number of texts and y is the number of months

400 texts will need to be sent each month because solving the equation 0.15xy+20y=0.20xy+0y

0.15xy+20y=0.20xy

-0.05xy+20y=0

-0.05xy=-20y

turn -0.05xy into (-y/20)x

(-y/20)x=-20y

((-y/20)x=-20y)/-y/20

x=-20y/-y/20

x=400

TURKEY plan because 0.15(500)y+20y is 95y and 0.20(500)y+0y is 100y, meaning TURKEY would be cheaper.

Investing is a game of chance. Suppose there is a 36% chance that a risky stock investment will end up in a total loss of your i
Sergio039 [100]

Answer: P(x ≥ 1) = 0.893

Step-by-step explanation:

We would assume a binomial distribution for the outcome of the investment. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 36% = 36/100 = 0.36

q = 1 - p = 1 - 0.36

q = 0.64

n = 5

Therefore,

P(x ≥ 1) = 1 - P(x = 0)

P(x = 0) = 5C0 × 0.36^0 × 0.64^(5 - 0)

P(x = 0) = 1 × 1 × 0.107

P(x = 0) = 0.107

P(x ≥ 1) = 1 - 0.107 = 0.893
