Unfortunately, you haven't shared the instructions for this problem. My guess is that you are to evaluate <span>P(x)= x^3+4x^2-8x-6 for x = a = -2.
If that's the case, then
P(-2) = (-2)^3 + 4(-2)^2 - 8(-2) - 6. This simplifies to:
= -8 + 16 + 16 - 6 = 18 (answer)</span>
Answer:
solution given a-d ,a, a+d, a+2d are in A.P
according to the question
sum of 4 terms =12
a-d+a+a+d+a+2d=12
4a+2d=12
2a+d=12/2
d=6-2a
again
3rd + 4rt term =14
a+d+a+2d=14
2a+3d=14
substituting value of d
2a+3(6-2a)=14
2a+18-6a=14
18-14=4a
a=4/4=1
again
d=6-2×1=4
first term =a-d=1-4=-3
second term =a=1
third term =a+d=1+3=4
forth term =a+2d=1+3×2=7
Answer:
the method we follow is area of the triangle is 12bh b is base and h is the height of the triangle
Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
The lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
