1). You will have to divide 256/8 because you will need to know how many buses are needed. By dividing these two the total Number of us is needed for a total of 256 people are 32 buses in total.
2). Just divide 350/27 and you will get approximately 13 cupcakes per student. Multiply your answer to 350 divided by 27 by 27 and you will get 324. Then subtract 324 from 350 and you will get 26. So each student receives 12 cupcakes and the teacher receives 26 cupcakes. I’m sorry I’m not that sure but I answered the rest for you
3). Find the common denominator of 2/3 and 1/5 which is 15.
2/3=10/15 and 1/5=3/15
The answer will be 13/15
4). Sane thing for number 4, find a common factor between 8 and 6 which is 24
3/8=9/24
And 5/6=20/24
Add them and you will get 29/24
Since 29/24 is an improper fraction write this improper fraction as a mixed number which will be 1 5/24.
Hope this really helps for your review and good luck! :)
< 1 and < 2......adjacent angles...because they have a common side and a comon vertex
< 1 and < 2.....complimentary angles....because when added, they equal 90
Answer:
0.07378
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ/√n, where
x is the raw score = 65 inches
μ is the population mean= 64.5 inches
σ is the population standard deviation = 2.99
n = 75
z = 65 - 64.5 /2.99/√75
z = 0.5/0.345255461
z = 1.4482
Probability value from Z-Table:
P(x<25) = 0.92622
P(x>25) = 1 - P(x<25)
= 1 - 92622
= 0.07378
The probability that the mean height for the sample is greater than 65 inches is 0.07378
Answer:
20
Step-by-step explanation:
5x4= 20
1. The slope is 12 and the y-int. Is -4 2. The slope is 1 and the y int. Is 3 3. The slope is 3 and the y-int. Is -6
