Step one:
Given data
Jennifer had $256.86
She made a deposit of $43.78
Required
The total amount in the account

Answer:
-7,340,032
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
b= -2, b2 +6b +9
=-2(2)+6(-2)+9
=-4-12+9
=4+9-12
=13-12
=1
So we are given that the mean is 42% and the sd (standard deviation) is 8%
Assuming our data is normal we can use the 68-95-99 rule
So one thing you should realize is that 42% + 8% is 50% which is passing. That is one standard deviation higher. So we use:
100 - 68 - 13.5 - 2.35 - 0.15 = 16. That means 16% of students passed the test. Which is terrible. They probably need to hit the books more.
Anyways if you have any question feel free to message me!
Hopes this helps!
