Answer:
Step-by-step explanation:
We realize what we need to do and that is take the total and divide by 4
= 78/4 19.5 and multiply by 3 = 58.50 rounded up always last step to 59
Now we know wifey has 59 and her man has 1/3 = 19
59 +19 = 78 videos.
Now for x x= 19
4x -1x = 78 - x
4x -1x = 78 - x
78-19 = 3x
3x = 59
x = 19
Answer:
a) Mean = 1205
Standard Deviation = 2.89
b) P( 1192 < x < 1204) = 0.4
Step-by-step explanation:
We are given the following information in the question:
a = 1200, b = 1210
We are given a uniform distribution.
a) Mean:
Standard Deviation:
b) P( 1192 < x < 1204)
![=\displaystyle\int_{1192}^{1204} f(x) dx\\\\=\displaystyle\int_{1200}^{1204} (0.1) dx\\\\=0.1[x]_{1200}^{1204} = (0.1)(1204-1200) = 0.4](https://tex.z-dn.net/?f=%3D%5Cdisplaystyle%5Cint_%7B1192%7D%5E%7B1204%7D%20f%28x%29%20dx%5C%5C%5C%5C%3D%5Cdisplaystyle%5Cint_%7B1200%7D%5E%7B1204%7D%20%280.1%29%20dx%5C%5C%5C%5C%3D0.1%5Bx%5D_%7B1200%7D%5E%7B1204%7D%20%3D%20%280.1%29%281204-1200%29%20%3D%200.4)
Answer:
18 pieces
Step-by-step explanation:
divide 30 by 5
you'll get 6
so one-fifth is equivalent to 6 of the pieces
multiply 6 by 2
you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats
subtract 12 from 30
30 - 12 = 18
So she took 18 pieces to school.
Hello! Your answer was 19! There is no possible way for me to show you how to work this out using base ten blocks! Hopefully you can work it out in your head next time! :)
Borrowing money is a way to purchase something now and pay for it over time. But, you usually pay “interest” when you borrow money. The longer you take to pay back the money you borrowed, the more you will pay in interest. It pays to shop around to get the best deal on a loan.
