Answer:
So the correct system of hypothesis for this case would be:
Null hypothesis:
Alternative hypothesis:
On the other way would be:
Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
1) Previous concepts
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".
2) Solution to the problem
On this case we want to test is but we can rewrite this expression like this:
And if we reorder this las expression we got this:
So the correct system of hypothesis for this case would be:
Null hypothesis:
Alternative hypothesis:
On the other way would be:
Null hypothesis:
Alternative hypothesis:
Answer:
2.5, 2.75, 3.7, 4¾ (4.75), 5.5, 29/5 (5.8), 6, 21/4 (7)
Step-by-step explanation:
I converted the fractions into decimals to make it easier to order. Hope this helps.
We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us with 27.75 and a shirt cost 14 and 50 cent .
SO you need to divide 27.75 in 14 and 50 cents which is equal to
14 plus 14 equals 28
75 plus 50 equals 1 and 25 cents

Answer:
y = -x +8
Step-by-step explanation:
The slope intercept form of a line is given by
y = mx+b where m is the slope and b is the y intercept
4x + 4y = -32
Subtract 4x from each side
4x-4x + 4y =-4x -32
4y = -4x -32
Divide each side by 4
4y/4 = -4x/4 -32/-4
y = -x +8
The slope is -1 and the y intercept is 8
