Answer:
C. 13
Step-by-step explanation:
from on online source, the question should be placed as thus:
Of the following integers, which is the closest approximation to (√2 + √5)^2 ?
A. 7
B. 10
C. 13
D. 15
E. 17
This is known as Algebraic expression. So we have to expand to simplify further
using this identity th (a+b)^2 = a^2 + b^2 +2ab
(√2 + √5)^2 =
(√2 + √5)(√2 + √5)
................Expansion of the above
2 + 5 + 2√10
~ 2 +5 + 2(3)
C. 13
Answer:
The value of the test statistic is
Step-by-step explanation:
Our test statistic is:
In which X is the sample mean, is the expected value,
is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that
Test Statistic:
The value of the test statistic is
2 ounces
using the conversion
1 pound = 16 ounces ⇒ = 8 ounces
Divide 8 by 4 to calculate amount for each cone
amount = 8 ÷ 4 = 2 ounces
