Answer:
233.5 in²
Step-by-step explanation:
First we have to find the slant height.
5²+14²=c²
25+196=c²
221=c²
c=14.866
Now we can find the lateral area.
rl
(5)(14.866)
=233.51566
To the nearest tenth=
233.5 in²
The relationship between variance and standard deviation is :
Standard deviation = sqrt (variance),
Variance = standard deviation^2.
hope this help
Answer:
2.
Step-by-step explanation:
-10 divided by -5 is 2. The two negatives cancel each other out.
A 95% confidence interval on the z-table is 1.96.
Now find the standard error using the formula: standard deviation / square root sample size:
0.7 / √100 = 0.07
Multiply to the confidence interval: 1.96 x 0.07 = 0.137 = 0.14
Now add and subtract tot he average weight:
14 - 0.14 = 13.86
14 + 0.14 = 14.14
The answer is 13.96 ≤ u ≤ 14.14
