Answer:
1. x = 12
2. x = 5
Step-by-step explanation:
1. -222 = -2x - 12x - 54
-222 = -14x - 54
-168 = -14x
x = 12
2. 154 = 2x + 12x + 84
154 = 14x + 84
70 = 14x
x = 5
Answer:
1. 80
2. 80
3. 40
Step-by-step explanation:
The question requires us to Use the sample size of 200 to find the expected frequency for categories A, B and C
1. (Category proportion)(sample size)
eA = 0.40x200
= 80
2. (Category proportion)(sample size)
eB = 0.40x200
= 80
3. (Category proportion)(sample size)
eC = 0.20 x 200
= 40
The answers are 80, 80 and 40 respectively.

Answer:
1.875
Step-by-step explanation:
Because your - 12 from 10=2 and subtracting another 1/8 so your answer is
10 7/8
And 7/8=87.5 or 0.875 or just 7/8.
So put those together 1.875 or 10 7/8
Hope this helps have a great day:)
Plug in numbers. if originally, it was V=1/2 * 1 * 1 * 2=1
<span>tripling the dimensions would be V=1/2 * 3 * 3 * 6=27 </span>
<span>it would be 27 times larger. this could also be found by 3^3, just as doubling would render 2^3
