The interval of 95% confidence, for normally distributed variables, is average +/- 2 * standard deviation:
(-2*standard deviation + average , average + 2*standard deviation)
(-2*18 + 62.5 , 2*18 + 62.5) = (-36 + 62.5 , 36 + 62.5) = (26.5 , 98.5)
Answer: option D)
We shall have to use distribution here.
The number outside the parenthesis gets distribute with the numbers inside.
This is called distributive property.
We know the distributive property is
a(b+c) = a × b + a ×c
Using this property for
5(4 x+2)
= 5× 4x + 5 × 2
Now 5 times 4x = 20x
5 times 2 = 10
So we get
5(4 x+2) = 20 x + 10
Option A) is the right answer.

Answer:
7
Step-by-step explanation:
We can see that x is equal to 7 and that is we use the exponent of 2 it equals 49 if we divide this by 2 we get 24. 5 and add this by the left over 3.5 gives us 28 and divide this by 2 and we get 14. After this you always need to remember to divide your answer by 2 which gives us 7.
