X=16
Divide 44 by 11 you get 4
Same with 52 and 13
Multiply 4 and 4
Answer:
d. H0:
vs.
Step-by-step explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
On this case the Management try to determine if there is a difference in the average investment/quad between using electricity and using gas. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.
Null hypothesis :
Alternative hypothesis:
Or equivalently:
Null hypothesis :
Alternative hypothesis:
Other important thing is that on the alternative hypothesis we never can have the symbol equal.
So on this case the best options is:
d. H0:
vs.
Answer:
The perimeter is 22.
Step-by-step explanation:
If you turn this shape into a rectangle, the perimeter doesn't change.
The width is given, it is 7.5. The height is BC+DE = 3.5
Then the perimeter is twice the width plus twice the height:
7.5*2 + 3.5*2 = 15+7 = 22
Answer:
since each item costs rs1263 we say
rs1263×22
27786
this means he spent rs27786
Her we now say rs47500-rs27786
=rs19714
This is to say that he has rs19714 left with him.

Answer:
D.
Width = 11 yards
Length = 15 yards
Step-by-step explanation:
P = 2(l + w)
Consider the width to be x.
The length would then be x+4.
We know that P = 52 yd
52 = 2(x + x + 4)
52 = 2(2x + 4)
52 = 4x + 8 (Subtract 8 from both sides)
44 = 4x (Divide both sides by 4)
x = 11
The width is x, so the width is 11 yards.
The length is x+4, so the length is 15 yards.
