Answer:
The correct answer is C, P < 0.005 and the conclusion is that the data given gave convincing evidence (P∠0.005) that the three tilts differs.
Step-by-step explanation:
If we go ahead to test the null hypothesis in the narrative given, we will achieve a chi-distribution of
Distribution Strikes expected frequency of strike
0.333 31 17.6667
0.333 14 17.6667
0.333 8 17.6667
If we complete the table above, and decide to determine the P-value using the table D, then the difference will be = c-1=3-1=2
Thus, p∠0.005.
Then we can conclude that C, is the answer.
x/3 -3 = x/9 +3
Subtract x/9 from both sides:
x/3 -3 -x/9 = 3
Simplify the left side:
2x/9 -3 = 3
Add 3 to each side:
2x/9 = 6
Multiply both sides by 9:
2x = 54
Divide both sides by 2:
x = 54/2
x = 27
Answer:5ft and 4in
Step-by-step explanation:
12 inches in foot
12÷3=4
1/3 of a foot is 4inches
Answer:
x=5
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 2: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 3: Divide both sides by 2.
2x2=102
x=5
Answer:
7/100
Step-by-step explanation:
This is literally what the percent sign means: "per hundred".
