I’m guessing it’s going to be third power
That would be C because there are two zeros right?
So you move two decimal places from 67.
And you get 0.67
Answer:
Answer:
Step-by-step explanation:
(a) 4x2 -- 3x - 2 = 0
x1,2 = -b ± √b²- 4ac
---------------------
2a
x1,2 = 3 ±√41
--------------
8
(b) (2x - 3)2 = 6
4x² -12x + 9 -6 = 0
4x² - 12 x + 3 = 0

Answer:
a) P=0.019
b) P=0.263
c) P=0.794
Step-by-step explanation:
We assume that the poll gives the population's proportion of respondents said that their jobs were sometimes or always stressful (p=0.8).
Then, a sample of size n=190 is taken.
The sample mean is:

The sample standard deviation is:

The probability that 140 or fewer workers find their jobs stressful is:

Note: a correction for continuity is applied.
The probability that more than 155 workers find their jobs stressful is

The probability that the number of workers who find their jobs stressful is between 145 and 158 inclusive is:

To solve this problem, we need to find out how much 8% is. Then discount it.
First we should turn 8% into a decimal which would be .08 now we can multiply .08 by 1,333.91 to get 106.71. Now subtract the two to get the discounted price!
Hope this helped:)
