Answer:
C
Step-by-step explanation:
Null hypothesis: hypthesis to test that there is no significant difference between the specific characteristic of a population. Analysts look to reject a null hypothesis
A. the shipping company's average delivery time is different from 3 days. This is an example of alternative hypothesis. Null hypothesis is writtien as a claim
B. This again is an example of alternate hypthesis. The claim that mean is 0.03 is rejected with the results
C. This is a claim
D. This is rejection of a claim that mean is 1 pound
E. This is rejection of claim that average delivery time is 3 days.
Use formula a squared equals to c squared minus b squared
40^2-24^2 is 1024
Square root of 1024 is 32.0
well, the subtotal or pre-tax bill is $23.50, now let's add the 8% tax and
so the post-tax bill is 23.50 + 1.88 = 25.38, and Jackie's tip is 20% of that
Answer: A = 112km^2
Explanation:
A = L x W
A = 14km x 8km
A = 112km^2
Answer: X=1
Explanation: When solving an equation, the goal is to isolate the variable (X). In order to do so, you must move everything else on the same side of the equation to the other side. So, in the equation 4=3+x, 3 is on the same side of the equation as X, so you must move it to the other side. When moving a number from one side of an equation to the other, you change the operation to the opposite: “+” becomes “-“, multiplication becomes division. Since the 3 in your equation is positive (+3), when you move it to the other side, it becomes “-3”. Thus:
4-3=x
1=x or x=1
