Answer:
-S = 15
Step-by-step explanation:
You are asked to find the opposite of the given value.
<h3>Opposite</h3>
The opposite of an integer value is obtained by changing its sign.
S = -15
-S = -(-15) = 15

<em>Additional comment</em>
Equivalently, you are multiplying by -1. The product of an even number of minus signs is a plus sign. We usually don't write the plus sign for a numerical value.
Answer:
f(3) = 9
Step-by-step explanation:
when we have f(x) that means function of any number. when we have a number in that function we plug it in our equation for all X's. Therefore, when we have f(3) we plug it in to all X's which looks like this
notice how I multiplied at the top first. you also want to apply the rules of PEMDAS.

Answer:
H0 : μ = 0.75
H1 : μ > 0.75
Step-by-step explanation:
Given :
Sample size, n = 125
x = 99
Phat = x / n = 99 / 125 = 0.792
Population proportion, P = 0.75
The hypothesis :
Null hypothesis :
H0 : μ = 0.75
Alternative hypothesis ;
Egates the null hypothesis ; since the sample proportion is greater than the the population proportion or claim "; then we use the greater than sign.
H1 : μ > 0.75
The answer in decimal is 1.75; and the answer in fraction form is 1 and 3/4. when you really think about it, fractions are just fancy ways of dividing. With this problem you can divide 21 by 12 on your calculator and get the 1.75.
