Lowest score earned to be qualified for an interview is 92.82
X : Marks scored in interview
X ~ N(80,100)
Here we need to find x such that P(X > x) = 0.10
using standard normal table,
we get P( z > 1.282) = 0.10
It's always easy to use Standard normal distribution to solve questions of normal distribution because standard normal is special case of normal distribution with mean 0 and standard deviation 1.
To convert x (which follows Normal distribution) to standard normal use: 
so, 
<em>hence,</em>
<em> </em>
Hence Lowest score earned to be qualified for an interview is 92.82

Answer:
Step-by-step explanation:
Use the order of operations.
Note: PEMDAS or BODMAS stands for:
<u>PEMDAS</u>
- <u>Parentheses</u>
- <u>Exponents</u>
- <u>Multiply</u>
- <u>Divide</u>
- <u>Add</u>
- <u>Subtract</u>
<u>BODMAS</u>
- <u>Brackets</u>
- <u>Order</u>
- <u>Divide</u>
- <u>Add</u>
- <u>Subtract</u>
<u>First, do parentheses.</u>
3+6*(5+4)÷3-7
(5+4)=9
<u>Do multiply and divide.</u>
6*9=54
54/3=18
<u>Then, rewrite the problem down.</u>
<u>Add.</u>
- <u>Therefore, the correct answer is "C. 14".</u>
I hope this helps, let me know if you have any questions.
that is 7X=10
= 1.42857143 or about1.42
Answer:
option (B) I'm certain of.
but if you are required to choose more than one then option (B) and (C) since polynomials are coefficients with power 2.
Step-by-step explanation:
Hope this helps.
Good luck.
Answer:
55th term
Step-by-step explanation:
Let Tn = -269
Then -269 = -5n + 6
-275 = - 5n
n = 55
