Answer:

-5/3

Step-by-step explanation:

In order to add or subtract fractions, the denominators need to be the same. In this case, the lowest common denominator would be 15abc.

So to get to that, you'll end up with 20abc/15abc - 45abc/15abc. Now you can subtract the numerators, which will give you -25abc/15abc. Once divided and simplified, your answer will be -5/3.

At a local high school football game, 150 randomly selected people were surveyed about the location of the concession stand. 108
Nesterboy [21]

Answer:

Option B

<em>The best point estimate of the proportion of people attending the game who believe that the concession stand should be closer to the stands is:</em>

<em>p = 0.72.</em>

Step-by-step explanation:

We want to estimate the proportion of people who feel that the stand should be closer to the stands.

We have a sample of 150 people, of which 108 think that the stand should be closer to the stands.

A point estimator for the proportion p is p\¨.

Where

p\¨ = \frac{x}{n}

Where n represents the size of the sample and represents the number of favorable cases.

We know that n = 150 and x = 108.

Then we can estimate p by the estimator p\¨

p\¨= \frac{108}{150}

p\¨ = 0.72

What is the value of x in the following equation, x/4 = -120? (Btw, it's x over 4 not division :)
Sergio039 [100]
If you mean by x over 4 that it is fraction then there is no different between it and divisions
x/4 = -120
x = -120 × 4 ( when division goes to the other side of equal it turns into multiplication)
x = -480

A. -480
