A cable car begins its trip by moving up a hill. As it moves up, it gains elevation at a constant rate of 50 feet/minute until i

asambeis [7]

Answer:

he cable car's elevation will be 750 feet after 15 minutes

Step-by-step explanation:

Given:

elevation, e =2,000 feet

rate, I = 50 feet/minute

The equation that models the car's elevation, e, after t minutes is e = |t

The cable car's elevation will be 750 feet after how many minutes?

since, e = It

for 2,000 feet = 50 feet/minute * t

t = 2000/50 =40minutes

using the same constant rate, I for 750ft, T =

since, e = It

for 750 feet = 50 feet/minute * t

t = 750/50 =15minutes

A manufacturer of televisions subjects the equipment to a comprehensive testing process for all essential functions before the t

Vikki [24]

Answer:

The value is $P(X \ge 9) = 0.9138$

Step-by-step explanation:

From the question we are told that

The probability of passing the test is $p = 0.95$

The sample size is n = 10

Generally the distribution of the comprehensive testing of equipment follows a binomial distribution

i.e

$X \~ \ \ \ B(n , p)$

and the probability distribution function for binomial distribution is

$P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}$

Here C stands for combination hence we are going to be making use of the combination function in our calculators

Generally the probability that at least 9 pass the test is mathematically represented as

$P(X \ge 9) = P(X = 9 ) + P(X = 10 )$

=> $P(X \ge 9) = [^{10}C_9 * (0.95)^9 * (1- 0.95)^{10-9}] + [^{10}C_{10} * (0.95)^{10} * (1- 0.95)^{10-10}]$

=> $P(X \ge 9) = [0.3151] + [0.5987]$

=> $P(X \ge 9) = 0.9138$
