This is really easy, because 8m is 200% you have to divide it in half to figure out the 100% which is 4... now you have to find the 75%. all you have to do is divide 4 by 25% which is 3.
| X | 1 | 2 | 4 | 5 | 10 |
| Y | 4 | 8 |16|20| 40 |
Answer:
-2.8
Step-by-step explanation:
Given that:
Mean, μ = 78
Standard deviation, σ = 5
Omar's score, x = 64
The Zscore of Omar's score :
Zscore = (x - μ) ÷ σ
Zscore = (64 - 78) / 5
Zscore = - 14 / 5
Zscore = - 2.8
Hence, Omar's exam score is - 2.8
Answer:
The answer is 463 inch cubed
Step-by-step explanation:
you do 8 x 8 x 7 which will give you 448 volume for just the cube.
then you do 5 x 3 x 1 = 15
you add 448 with 15 you will get 463
So what you do is see all the denomenators and factor them (denomenaotrs are the bottom numbres)
10,4,10,25
10=2 times 5
4=2 times 2
10=2 times 5
25=5 times 5
we need to include all of them so we need at leas two 2's, and two 5's
2 times 2 times 5 times 5=100
leact common denomator is 100
