Answer:
1. 1/2(5)(2) = 5 yd squared
2. 1/2(6)(8) = 24 ft squared
3. 1/2(12.4)(18) = 111.6 cm squared
4. 1/2(3.5)(6) = 10.5 m squared
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

Hello,
Please, see the attached file.
Thanks.
Answer:
1. 12
2. Multiply
3. 27
Step-by-step explanation:
These make the most sense because you are supposedly trying to find factors of 12, that multiply to 27. It can't be negative numbers I don't think. And there can't be factors of 27 that multiply to 12.
I'm so sorry if this is incorrect, but I hope it helps!
