Answer:
I think the answer is B. The equation has infinitely many solutions.
Step-by-step explanation:
4(3x + 4) = 15x + 12 - 3x + 4
*group like terms so 4(3x+4) = 15x - 3x + 12 + 4
*add similar elements 15x - 3x = 12x
*add the numbers 12 + 4 = 16
*Expand to 12x + 16 - 16 = 12x + 16 - 16
*You simplify 12x = 12x
*Subtract 12x from both sides
*Then Simplify which is 0
Which means Both sides are equal to 0
True for all X
Answer:
D. Alice used empirical probability, Mark used theoretical probability.
Step-by-step explanation:
Alice used empirical probability because she actually flipped the coin 100 times but Mark assumed the coin was fair and didn't actually test it, using theoretical probability.
Answer:
4 students
Step-by-step explanation:
Although I am not sure if I am completely correct. I’ll try my best.
<u>We know:</u>
The numbers 0-12 on the frequency table is the number of windows.
The numbers on the bottom is the amount of students.
-
<u>What we can see:</u>
As we can see..
- the 0-4 section in the table shows that only 0-4 students have 9 windows.
- The 5-9 sections shows that only 5-9 students have 10 windows.
- The 10-14 sections shows that 10-14 students have 0 windows.
- The 15-19 sections shows that 15-19 students have 4 windows.
- The 20-24 sections shows that 20-24 students have 2 windows.
-
<u>Calculations:</u>
Since the number of students that have the amount of windows less than 10 is 4 (0-4 section) and 0 (10-14 section)
Add.
4+0
= 4
Therefore, 4 students have less than 10 windows.

Answer:
The required amount is $94.23.
Step-by-step explanation:
It is given that Nolan began a savings account three years ago and the value of his account after x years is

Anias started an account today and the value of her account is

We have to find the amount of money that would she have had to invest to have the same amount of money she has now.
Let the required amount be P.
If Anias started saving x amount in the savings account three years ago, then today the value of her account is

The current value is 100.

Divide both sides by 0.0612.



Therefore the required amount is $94.23.
