Answer:
Renee has 9 Chocolate chip cookies and 3 peanut butter cookies.
Step-by-step explanation:
This is a system of equations:
C + p = 12
C = 3P
All you need to do is substitute C for 3P in the first equation.
C + P = 12
3P + P = 12
4P = 12
Divide both sides by 4
4P/4 = 12/4
P = 12/4
P = 3
Now, substitute P for 3 in the first equation.
C + P = 12
C + 3 = 12
Subtract 3 from both sides
C + 3 - 3 = 12 - 3
C = 12 - 3
C = 9
C = 9, P = 3
Answer:
a
Step-by-step explanation:
Answer:
y ≤ 1x-1
Explanation:
line is not dotted = ___ than or equal to
shaded area below line = less than
so: ≤
--
y=mx+b
y intercept -1 (line intersects y line on -1)
y=mx-1
points (1,0) (0, -1)
find slope
---
in conclusion, y ≤ 1x - 1
For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

What is the combination?</h3>
A combination is a mathematical technique that determines the number of possible arrangements.
Let's we have to define
A, B, and C, as the regions in the spinner.
So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:
The outcome of spin 1, the outcome of spin 2, outcome of spin 3.
The total number of different outcomes will be:
3^3 = 27

Answer:
Step-by-step explanation:
8 .) Probability of students has no pets in senior = No. of outcomes favourable / Total no.of outcome
= 15 / 24
9.) Probability of students has pets in junior = No.of outcomes favourable / Total no. of outcomes
= 37/52
