I am 100% sure the answer is a.4
Because it was (2,3) then became (8,12)
2*4= 8 and 3*4= 12
The numbers 2 and 3 were multiplied by 4 to get 8 and 12
The sales last year of the company is 5617
<h3>How to determine the sales last year?</h3>
The given parameters are:
Company sales = 6740
Percentage increase = 20%
The sales of the company last year (x) to date is calculated as:
Company sales = (1 + Proportion) * Last year sales
Substitute the known values in the above equation
6740 = (1 + 20%) * x
Evaluate the sum
6740 = 1.2 * x
Divide both sides by 1.2
x = 5617
Hence, the sales last year is 5617

A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.
Answer: The given z-score is false.
Explanation: We are given:
Mean, 
,
Variance, 
The z-score formula is given below:
Therefore, the z-score corresponding x=100 is 2
Therefore, the given z-score = 0.4 is false.
8x-32=8(x-4)
the lower common denominator is 8(x-4)², or 8(x-4)(x-4)
Answer:
There isn't one
Step-by-step explanation:
√q differs from √(q+1) by 1 only when q=0. The difference gets smaller as q gets larger.
___
Here, q=7x. The same logic applies.
