Answer:
E. 55 hours.
Step by step:
Multiple $15x40, equals $600
Subtract $600 from $937.50, equals $337.50
50% more over 40 hours is $22.50
Divide $337.50 by $22.50, equals 15
Add 15 to 40, equals 45
So she worked 55 hours to get paid $937.50
<span>Defective rate can be expected
to keep an eye on a Poisson distribution. Mean is equal to 800(0.02) = 16,
Variance is 16, and so standard deviation is 4.
X = 800(0.04) = 32, Using normal approximation of the Poisson distribution Z1 =
(32-16)/4 = 4.
P(greater than 4%) = P(Z>4) = 1 – 0.999968 = 0.000032, which implies that
having such a defective rate is extremely unlikely.</span>
<span>If the defective rate in the
random sample is 4 percent then it is very likely that the assembly line
produces more than 2% defective rate now.</span>
Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%

Step-by-step explanation:
The factored form would be (3x-9)(x-1)
The picture should help a bit
A=7 is what I got since this was a equation problem
