Answer:
Mean = 15.15
Standard deviation = 0.6062
Step-by-step explanation:
We are given a uniform distribution of quantity to be put in each bag.
Low and high filling weights:
14.1 pounds and 16.2 pounds
a = 14.1
b = 16.2
a) Mean:
b) Standard Deviation:
Answer:
He washed 4 cars.
Step-by-step explanation:
1. The variable that was unknown x amount of cars washed.
2.The equation I used was 110-50=15x
3. To solve this you subtract the 50$ from 110$ you get sixty dollars you do that to take out what he earned for his allowance. Then your equation is 60=15x so you divide each side by 15 and when you do that x=4
Answer:
y = 8
General Formulas and Concepts:
<u>Algebra I</u>
- Reading a Cartesian Plane
- Coordinates
- Functions
Step-by-step explanation:
What the question is asking is for the y-value when the x-value is equal. According to the graph, when x = 6, y = 8. Therefore, y = 8.
I'll do 22 for you. 22, 24, 26, 28, and 30, are very similar to each other.
PROPORTIONS:
Draw it out.
5/7 = either c/6, or b/5.
I'll do c/6
5/7 = c/6
solve for c
7c=30
c=30/7
now do the same thing to the remaining side, b.
there!
Answer is
When it's powered numbers, remember to choose the one with the largest power. For example,
And
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.
Hope this helps. - M
