Answer:
y = 1/3x - 4
Step-by-step explanation:
Lol lemme just write out the steps and if you're confused just comment and i'll get back to u.
x - 3y = 12
<u>-x.........-x</u>
-3y = -x + 12
<u>*-1...........*-1</u>
3y = x - 12
<u>/3........../3</u>
y = 1/3x - 4
<u />
And that is the equation in fully simplified slope/intercept form. I hope this helps!
Answer:
$13.16
Step-by-step explanation:
For each individual spin, there are two possible outcomes:
- There is a 1 in 38 chance of winning $175.
- There is a 37 in 38 chance of losing $5.
The expected value for each spin is the sum of the products of each outcome by their respective probability.
In 50 spins, the expected value is:
You can expect to lose $13.16 if you spin the wheel 50 times.
Answer:
Size of groups known: First and last questions (The rice and cups ones)
Number of groups known: Second and third questions (Cars and hats)
Step-by-step explanation:
In the first problem, you know that one sack is one group, and it tells you that each sack weighs 3 kg. Therefore, you know the size of the group (or a sack).
In the last one, you know that a table is one group and each table fits 4 cups. So, you know that the size of the group is 4 cups.
In the second and third questions, you know that each group is a row (cars) or "equal group" (hat) and that there are 4 of each. So, you know that there are 4 of each group, meaning you know the "number of groups"
Do not bring the 10 in first. 8x15 and 4x3.
Assuming that f(n+1) = f(n) is the full recursive definition, and that there are no typos, then this means that the nth term is equal to the (n+1)th term for any n where n is a positive whole number.
So
f(1) = f(2)
f(2) = f(3)
f(3) = 9
By the transitive property, f(1) = f(3) = 9. Therefore the answer is 9.
