Answer:
And for this case we have a significance level and then:
So then we have enough evidence to reject the null hypothesis. And we can conclude in favor the alternative hypothesis.
Step-by-step explanation:
For this case we have the following hypothesis:
And for this case we got the following hypothesis:
And for this case we have a significance level and then:
So then we have enough evidence to reject the null hypothesis. And we can conclude in favor the alternative hypothesis.
The answer is nonproportional.
Easy you have to subtract 95 by 8 then you get your answer hope it helped!
Answer: s= -8
Step-by-step explanation:
The gradient of the ski slope can ge used as the slope (literally) of a line equation:
y = mx + b,
where m is the slope and b the y-intercept (the value of y when x = 0).
The first slope would be y = -(1/3)x + b.
The slope is (-1/3) since the ski run is headed downhill. The second ski slope is assumed to have the same gradient ("two parallel straight ski slopes").
y' = -(1/3)x' + b
We may assume that b is the same for both slopes - they start and end at the same point.
We can find b by using the given point (2,-3):
y' = -(1/3)x' + b
-3 = -(1/3)(2) + b
-3 = -(2/3) + b [Add -(2/3) to both sides: (-3 + 2/3 = -9/3 + 2/3 = -7/3]
-7/3 = b
b = -(7/3)
The second ski slope, y', thus has the equation
y' = (1/3)x' -(7/3)
We want the value of s in (s, -5).
y' = (1/3)x' -(7/3)
-5 = (1/3)s -(7/3)
(1/3)s = -5 +(7/3) [-15/3 + 7/3 = -8/3]
(1/3)s = -(8/3) [Multiply both dies by 3]
s = -(24/3)
s = -8
I’d make the spinner slices into thirds that are even because there would be an equal chance for each slice to be chosen. If I were to spin the spinner, I would have an equal 33.33% chance that it would land on $3, $5, or -$6. This makes it fair because they would all have an equal chance to be chosen!
