To solve this problem, we should note that there are:
total questions = 100
questions answered correctly = 90
questions that needed additional clues = 10
1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:
Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)
Probability = (90/100)*(89/99)*(10/98)
Probability = 0.08256 = 8.26%
2. The second question finds for the probability that two consecutive needs additional clue, therefore:
Probability = (question 1 needed clue) * (question 2 needed clue)
Probability = (10/100)*(9/99)
Probability = 9.1*10^-3 = 0.91%
Answer:
1. The estimated probability that it would take at least three questions for Mary to need additional clues is 0.24
2. The estimated probability that Mary needed additional clues to answer two consecutive questions is 0.06

b) The graph of y = x^2 + 1 is drawn on
the axes on the left.
Use the graph to estimate the
values of x when y = 4.
Give your answers to 1 decimal
place.
Answer:
(-1.7,1.7)
Step-by-step explanation:
OK, first draw the line y=4.
It's a bit misleading- where you think 4 should go is actually 2!
Check the scale and draw down where the two points meet on the line. They should be the same.
You get -1.7 and 1.7
The value of x is [tex]x=\pm\sqrt{3}[/tex]

Answer:
y =-4
x = 1
Step-by-step explanation:
Add the two equations
4x - y + 6x + y = 8 + 2 add like terms
10x = 10 divide both sides by 10
x = 1 now to calculate y replace x in first equation by 1
4x - y = 8
4 - y = 8 subtract 4 from both sides
-y = 4 and y = -4

Answer:
1) $575
2) They'll markup the price by $3,240. After the markup, the retail price is $15,240
Step-by-step explanation:
1)
6% = 0.06
3750(0.06) = 225
225 + 350 = 575
2)
27% = 0.27
12000(0.27) = 3240
Profit = 3240
Price for retailer = Cost Price + Profit
Price for retailer = 12000 + 3240
Price for retailer = 15,240
Based on the table, how much more money would a person with a bachelor's degree earn than a person with an associate's degree over a 30 year career?
A) $16,000
B) $480,000
C) $1,095,000
D) $1,575,000
Answer:
B) $480,000
Step-by-step explanation:
Annual salary of a person with associate's degree
= $36,500
Over a 30 year career the person would earn;
= 30 × 36500
= $10,95,000
Now, annual salary of a person with bachelor's degree = $52,500
Over a course of 30 years he would earn;
= 30 × 52500
= $15,75,000
Difference = $15,75,000 - $10,95,000 = $480,000
So the person with bachelor's degree would earn $480,000 more than a person with associate's degree.

How many solutions does this equation have?
8z − 5 = 8z
Answer:
Zero
Step-by-step explanation:
Solve the equation by subtracting 8z from both sides:
8z − 5 = 8z
-5 = 0
-5 [tex]\neq[/tex] 0
This is a false statement, because -5 is not equal to zero.
This means that there are no solutions to the equation.
So, the equation has zero solutions
Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.
