Suppose you have already been waiting for one hour for a taxi. what is the probability that one arrives within the next 10 minut
Alona [7]

The probability of one arrives within the next 10 minutes when he already been waiting for one jour for a taxi is,

 

P (X > 70 | X > 60) = P (X > 10) = 1 – P (X ≤ 10) = 1 – {1 – e ^ -((1 / 10) 10)} = e ^ -1

= 0.3679

 

The probability of one arrives within the next 10 minutes when he already been waiting for one hour for a taxi is 0.3679

A rectangle has a perimeter of 204 feet. It's length is six feet longer than twice it's width. If L stands for the length of the
Ratling [72]

Answer:

L = 70

W = 32

Step-by-step explanation:

P = 2L + 2W

P 204 feet

W = x

L  = 2x + 6

P = 2L + 2W

P = 2*(2x + 6) + 2*x

P = 4x + 12 + 2x

P = 6x + 12

But we know that P = 204  So 6x + 12 = 204

6x + 12 = 204                    Subtract 12 from both sides

6x + 12 - 12 = 204 - 12       Collect like terms on the right

6x = 192                             Divide by 6

x = 192/6

x = 32

Answer

W = 32

L = 2*W + 6

L = 2*32 + 6

L = 64 + 6

L = 70

The sphere area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for pi. Round y
julsineya [31]

We are given

area of sphere is 200.96cm^2

it means that we are given surface area

so, we can use surface area formula

S=4\pi r^2

where S is surface area

r is radius

so, firstly we need to find radius or r

200.96=4\pi r^2

we can solve for r

r=3.9989cm

now, we can find volume

V=\frac{4}{3} \pi r^3

we can plug r

V=\frac{4}{3} \pi (3.9989)^3

now, we can find volume

V=267.86cm^3.............Answer
