Answer:
Francine is 13
Sonya is 23
Joey is 23
Step-by-step explanation:
J = 10 + F
S=2F-3
J=S
10+f=2F-3
10+F-F= 2F-F-3
10+3=F-3+3
F=13
S=2(13)-3
S=26-3
S=23
First, you would need to find out how much 1 sun visor would cost. To do this, you would divide $90 among the 12 sun visors.
$90 ÷ 12 = $7.50
It costs $7.5 per sun visor.
Next, you would need to create an equation to find out how much it will cost to buy 15 more sun visors.
($7.50 × 15) + $90 = $202.50
It will cost $202.50 in total to buy 12 visors plus another 15.
Now, the last thing you would need to do is calculate how much it would cost to buy 16 sun visors.
$7.50 × 16 = $120
It would cost $120 to buy 16 sun visors.
I hope this helps!

Answer:
34% of scores should fall between your score and the mean.
Step-by-step explanation:
Let <em>X</em> denote the score.
It is provided that X follows a normal distribution with mean 110 and standard deviation 15.
A students score, <em>x</em> = 95.
Compute the probability of scores that should fall between the student's score and the mean as follows:
Thus, 34% of scores should fall between your score and the mean.
The difference (subtraction) would be 3/6
