Answer:

The left end of the cable is 15 m above the roadway

Step-by-step explanation:

Let

x----> the horizontal distance from left end of cable (m)

y----> the height above roadway (m)

we know that

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The y-intercept is the height above roadway (m) when the distance from end of cable is equal to zero

so

The y-intercept is the point (0,15)

so

The left end of the cable is 15 m above the roadway

The expected values of the binomial distribution are given as follows:

1. 214.

2. 21.

3. 31.

<h3>What is the binomial probability distribution?</h3>

It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

For item 1, the parameters are:

p = 3/7, n = 500.

Hence the expected value is:

E(X) = np = 500 x 3/7 = 1500/7 = 214.

For item 2, the parameters are:

p = 0.083, n = 250.

Hence the expected value is:

E(X) = np = 250 x 0.083 = 21.

For item 3, the parameters are:

p = 1/13, n = 400.

Hence the expected value is:

E(X) = np = 400 x 1/13 = 31.

What is the value of x in the equation 7(4x+1)−3x=5x−13?
Citrus2011 [14]

Answer:

x = -1

Step-by-step explanation:

7(4x+1)−3x=5x−13

Distribute

28x +7 -3x = 5x -13

Combine like terms

25x+7 = 5x-13

Subtract 5x from each side

25x-5x +7 = -13

20x +7 = -13

Subtract 7 from each side

20x+7-7 = -13-7

20x = -20

Divide by 20

20x/20 = -20/20

x = -1
