Answer: 10.09 or 15.03
explanation:
Formula for confidence interval(CI) is CI = x ± z * (sd/ Sqrt(n))
Where x is mean = 12.56
z is value for normal distribution 99% confidence =2.58
sd is standard deviation=3.03
Sqrt is square root
n is sample population = 10
CI =12.56±2.58*(3.03/sqrt(10)
=12.56±2.47
=15.03 or 10.09
With 99% confidence, the average number of commercial minutes is between 10.09 and 15.03 minutes, based on sample data.
C/D is the answer i think
Answer:
The value of polynomial for x = 2 that is f(2) will be 32
Step-by-step explanation:
We have given polynomial
We have to find the value of f(2)
We have to find the value of polynomial for x = 2
So for finding this value we have to just put x = 2 in polynomial
So f(2) will be
So the value of polynomial for x = 2 will be 32
If we were to view the ramp from its side, the profile would resemble a right triangle with a 90 degree angle where the sofa meets the floor.
In this case, the two legs of the right triangle are 55 inches and 28 inches, and we looking for the length of the hypotenuse.
We can use Pythagorean Theorem which states:
where a and b are the legs, and c is the hypotenuse.
c = 61.717 inches
To the nearest tenth, the answer is 61.7 inches.
Answer:
24-6x
Step-by-step explanation:
To distribute, you multiply the number outside the parenthesis by each number inside, keeping in mind the signs.
So, 6(4-x) = 6(4) - 6(x) = 24-6x
