Answer:
22 pi cm ( 69.12 cm)
Step-by-step explanation:
pi * d = circumference = pi * 2 * r = pi * 2 * 11 = 22pi cm
Answer:
A) a small variance for the difference scores and a small standard error
Step-by-step explanation:
Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.
Answer:
-3c^2 +6
Step-by-step explanation:
The equation will be an identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combining the c^2 terms.
The contents of parentheses simplify as follows:
... (4c^2 -7c^2 +6) = (c^2(4 -7) +6) = (-3c^2 +6)
The product is 10√14 +8√21 +30√3 +36√2
Step-by-step explanation:
Given the question as;
( 2√7 +3√6)(5√2+4√3)
Distribute
2√7(5√2+4√3) + 3√6 (5√2+4√3)
open brackets
2√7 × 5√2 + 2√7 × 4√3 + 3√6×5√2+3√6×4√3
2×5×√7×√2 + 2×4×√7×√3+3×5×√6×√2 + 3×4×√6×√3
10×√14 +8√21+15√12+12√18-----------------------------simplify √12 and √18 further
10√14+ 8√21 + 15×√4×√3 + 12×√9×√2
10√14 +8√21 +15×2×√3 + 12×3×√2
10√14 +8√21 +30√3 +36√2

Answer:
<em>The 95% confidence interval for the mean waste recycled per person per day for the population of Montana.</em>
<em>(0.58701 , 1.41299)</em>
Step-by-step explanation:
<u><em>Step:-1</em></u>
Given that the size of the sample 'n' =12
Given that mean of the sample x⁻ = 1.0 pounds
Given that the standard deviation of the sample (S) = 0.65 pounds
<u><em>Step:- 2</em></u>
<em>The 95% confidence interval for the mean waste recycled per person per day for the population of Montana.</em>
