Answer:
A
Step-by-step explanation:
B,.C and D are wrong because
B states all. The hypothesis stated above does not mention all samples
.
C. Mentions a mean. Per the hypothesis, the percentage of defective screens was an actual number and not a mean.
D. The question is not referring to a standard deviation
Answer:
C
Step-by-step explanation:
- means you go to the left on a graph (if the number is in the x position) or down on a graph (if it's a negative in the y's place) in this case it's a negative 3 in the x's place so we go left 3 times. Then we go up 4 where we will meet the C coordinate.
2 tsp for 4 cups flour
1 tsp for 2 cups
For 10 cups it would be 5tsp
Log^7(12)=log^7(2*2*3)=log^7(3)+log^7(2)+log^7(2)
so log^7(12)-log^7(3)=log^7(3)+log^7(2)+log^7(2)-log^7(3)
=log^7(2)+log^7(2)
true

Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
2(3x - 7) = 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Division Property of Equality] Divide 2 on both sides: 3x - 7 = 8
- [Addition Property of Equality] Add 7 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
