Answer:
B) n3 + 4n2 + 8n - 16
Step-by-step explanation:
combine 2n3 - n3 = n3
4n2 stays the same
combine -7 - 9 = -16
8n stays the same
n3 + 4n2 + 8n - 16
Answer:
x^12
Step-by-step explanation:
when multiplying with exponents, keep base and add exponents
when dividing with exponents, keep base and subtract exponents
Solution
To find Which two numbers on the number line has an
absolute value of 3
Absolute value means " how far a number is from
zero " .
"3" is 3 away from zero .
and " -3 " is also 3 away from zero .
i.e
| 0 - 3 | = 3
| 3 - 0 | = 3
So , the absolute value of "3 " is 3
similarly , absolute value of "3 " is 3 .
Hence , the two numbers are -3 and 3
The standard deviation will be 6816.9645.
<h3>How to compute the standard deviation?</h3>
From the information given, the mean is 74000 and X is given as 60000.
P[(Z < (-60000 - 74000)/SD] = 0.02
Note that 0.02 will be -2.0537 under the normal distribution table.
-14000/SD = -2.0537
SD = -14000/-2.0537
SD = 6816.9645
