Answer: a. 0.9876
Step-by-step explanation:
Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.
and 
sample size : n= 25
Let x denotes the total body protein in healthy adult men in the sample.
Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-

∴ The correct answer is a. 0.9876
PART A:
The option that would be equal to figure ABC would be A scalene triangle with only one angle that measures 80* because the other angle is not shown in this phrase so we could say that the other angle is 50* then it would be equal to figure ABC, and a scalene triangle is a triangle with three uneven, unequal sides,
Therefore the answer would be,
C. A scalene triangle with only one angle that measures 80*
Given exponential expression :
.
<em>According to exponents of exponent rule, we need to distribute whole exponent over exponents of inside terms of parenthesis.</em>
We are given whole exponent 2 there.
We can apply exponents of exponent rule.
Therefore,



Therefore, 
<h3>Correct option is second option

</h3>
From the figure, segment QP is in the ray RP and RP contains N and Q in between
so from the options, the two rays will be : ray QP and ray NP
For SU :
segment SU is in the ray RU and RU contains S and T in between,
so from the options again, the two rays will be : ray RU and ray SU
