Just substitute 5 into a and -2 into k
Answer:
8
Step-by-step explanation:
It depends what mathematics you know
Perhaps the most basic way would be by approximation. You could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.
Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.
Try 8: 8*8*8=512.
Answer: A) 0.016
Step-by-step explanation:
The standard error is also known as the standard deviation of sampling distribution.
Formula : 
Given : The proportion of respondents approve the job that President Barack Obama was doing handling the economy : 
Sample size : n= 1000
Then, the standard error (SE) of
is

Hence, the standard error (SE) of
is 0.016 .
Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102
Best of Luck!
The decimal representation for 4/5 would be,
0.8
Hope it helped. It's all I could do.
