2 is the answer im pretty sure
Answer:
100
Step-by-step explanation:
40 / 100= .4
.4 x 45 = 18
18/18= 1
1x 100= 100
That is a direct division, if you are confused by the decimal point, lets get rid of it! We can get rid of the decimal point multiplying the upper and lower parts of the division by 10, lets do it:
<span>62.8 / 3
= 10*</span><span>62.8 / 10*3
= </span><span>628 / 30
we can try to reduce the fraction dividing by 2 the upper and lower parts:
= 314/15
and now we have to make the operation:
= 20.93</span>
Answer:
Step-by-step explanation:
Sum = -14
Product = - 32
So, the factors = -16 , 2
When we add -16 +2 = -12 and when we multiply it is -32
w⁴ - 14w² - 32 = w⁴ - 16w² + 2w² - 16 * 2
= w²(w² - 16) + 2(w² - 16)
= (w² - 16)(w² + 2)
= (w² - 4²)(w² + 2)
= (w + 4)(w - 4)(w² + 2)
Answer:
The sample is the 150 randomly selected customers.
Step-by-step explanation:
When you survey a group of people, to gauge whaever you are interested, these people are what makes your sample.
In this question:
Nick surveys 150 randomly selected customers to determine whether or not they were satisfied.
