Answer:

Option B) add 5 to both sides of the equation

Step-by-step explanation:

we have

$x^{2}+18x+76=0$

step 1

Add 5 to both sides of the equation

$x^{2}+18x+76+5=0+5$

$x^{2}+18x+81=5$

step 2

Rewrite as perfect squares

$(x+9)^{2}=5$

Morton needs to have his car repaired. The auto repair shop charges a fixed dollar amount for labor, plus another dollar amount

Mrrafil [7]

The y-intercept of the function is $50 and it represents the fixed amount for the labor charges.

<h3>How to find the y-intercept of a graph?</h3>

From the attached graph, we see that the x-axis is represented by time in hours while the y-axis is represented by labor charges in dollars.

Now, from the graph we see that the coordinates are;

(0, 50), (1, 125), (2, 200), (3, 275), (4, 350)

Now, the y-intercept of a linear graph is simply the point at which the graph crosses the y-axis.

In this graph attached, we see that the y-intercept is at the coordinate (0, (0, 50).

Thus, we conclude that the y-intercept of the function is $50 and it represents the fixed amount for the labour charges.

Nitella [24]

Answer:

Option A is correct.

A uniform distribution.

Step-by-step explanation:

Complete Question

T-Mobile sells 6 different models of cell phones and have found that they sell an equal number of each model. The probability distribution that would describe this random variable is called:

A) Uniform Distribution

B) Continuous Distribution

C) Poisson Distribution

D) Relative Frequency Distribution

Solution

A uniform distribution is one in which all the variables have the same probability of occurring.

It is also known as a rectangular distribution, as every portion of the sample space has an equal chance of occurring, with equal length on the probability curve, leading to a rectangular probability curve.

And for this question, 6 different models of phones sell an equal number, hence, the probability of selling each model is equal to one another, hence, this is evidently a uniform distribution.

Hope this Helps!!!
