Interesting question about feet and inches. The best way to solve this problem is to ask yourself how many inches are in a foot. Since there are 12 inches in every foot then the length of 2'8" can be written as (2*12)" + 8". Which is 24+8 or 32 inches. The second number (1'6") can be written as (1*12)"+6" which is 18 inches. 32 + 18 = 50 inches. Or, if you want to change this back into feet and inches just divide it by 12. 50/12 is 4 R. 2. So 4'2".
The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24
Answer:
D
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Construct a perpendicular bisector of segment AB.
Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.
So, points A and B will be at the same distance from the intersection point.
If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.
