Answer:

Step-by-step explanation:
The rate of change is measured by the slope of the line in this linear table.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table
m =
=
=
← rate of change
Answer:
Option D is correct
Step-by-step explanation:
Alex has 7 textbooks.
=>The number of ways to place 4 out of 7 books on the shelf is 7P4.
=> Option D is correct
Hope this helps!
So they get $2 on day 0, $2 on day 2, $3 on day 4, $5 on day 5, $2 on day 6, $1 on day 7, $2 on day 8, $4 on day 10, $1 on day 11, $2 on day 12 and $1 on day 15.
$2 appears 5 times
$1 appears 3 times
$4 appears once and $5 appears once
The median would be ($2*5 + $1*3 + $4 + $5)/(5+3+1+1) = $22/10 = $2.2
The range of the allowances is highest - lowest = $5-$1 = $4
Edit: It might also have a range of $5 and a median of $1.37 because the lowest it goes to is $0 on some days though. Try both.
Answer:
Two accounts each began with a deposit of $10,000. Both accounts have rates of 6.5%, but one account compounds interest once a year while the other account compounds interest continuously. Make a table that shows the amount in each account and the interest earned after one year, five, years, ten years, and 20 years.

Answer:
B-91%
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: arriving home after 7 p.m.
Event B: getting home by bus.
When he chooses to get home by bus, he arrives home after 7 p.m. 25 percent of the time.
This means that 
Because the bus is cheaper, he uses the bus 70 percent of the time.
This means that 
Probability of getting home after 7 p.m.
70% of the time he uses bus, and by bus, he arrives arrives home after 7 p.m. 25 percent of the time.
100 - 70 = 30% of the time he uses the car, and by car, he arrives home after 7 p.m. 6 percent of the time.
So

What is the approximate probability that Matthew chose to get home from work by bus, given that he arrived home after 7 p.m.?

Rouding up, 91%.
So the correct answer is:
B-91%
