Answer:
75%
Step-by-step explanation:
You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Given the following
Total cards = 4 (6,7,8,9)
If the card is not 9, the required card will be (6,7,8)
Number of cards that are not 9 is 3
Probability = expected/total
Pr(not 9) = 3/4
express as percent
Pr(not 9) = 3/4×100
Pr(not 9) = 75%
B- 18 units to the left of zero
Answer:
Percentage of students who scored greater than 700 = 97.72%
Step-by-step explanation:
We are given that the College Board originally scaled SAT scores so that the scores for each section were approximately normally distributed with a mean of 500 and a standard deviation of 100.
Let X = percentage of students who scored greater than 700.
Since, X ~ N(
)
The z probability is given by;
Z =
~ N(0,1) where,
= 500 and
= 100
So, P(percentage of students who scored greater than 700) = P(X > 700)
P(X > 700) = P(
<
) = P(Z < 2) = 0.97725 or 97.72% Therefore, percentage of students who scored greater than 700 is 97.72%.

Answer:
option 2
Step-by-step explanation:
I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.
4 years = 12 x 4 = 48 months
Option 1: 500 + 195 (48) = 500 + 9360 = 9,860
Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310
If he can wait six months, it will save him about $3,500 to go with Option 2.
