From there we can see that because x equals both to a and b, it must be that a = b.
The answer would be 97 when rounded to the nearest mile (if you were were going for length)
Answer:
This was an observational study.
Step-by-step explanation:
Given is that parents of children completed a questionnaire on the child’s light exposure both at present and before the age of 2 years.
This was an observational study since there is no treatment or control group.
We know that treatment, control groups or treatment groups are not specific to randomized control experiments.
This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5. x^2-10x+25 = (x - 5)(x - 5). Note how (-5)(-5) = +25, and how -5x - 5x = -10x.
The roots are { (x-5), (x-5) }.
Answer:
$15.35104
Step-by-step explanation:
Step 1
Calculate how much is 7.2% raise
$14.32 × 7.2%
= $14.32 × 7.2/100
=$ 1.03104
Step 2
Jack's hourly rate after his raise is
$14.32 + $ 1.03104
= $15.35104
