Answer:
4/3
Step-by-step explanation:
2(5y-7) > -24
distributive property: 10y - 14 > -24
add 14: 10y > -10
divide by 10: y> -1
Answer:
3, 75
Explanation:
You divide the fraction and you put it next to the number
I'm not exactly sure what kind of answer you are looking for but angle L would also be 72 degrees. This is because 36 (K) + 72 (J) = 108 and a triangle's angles must add up to 180 so 180 - 108 = 72 (L) . This also makes sense because it is an isosceles triangle so two of the angles must be the same because two of the sides are the same length.
Answer:
The 99% lower confidence bound for the true average weight loss is 3.98 pounds.
This means that we can be 99% sure that the mean weight loss for all obese adults on a low-carb diet is positive.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 11 - 6.02 = 3.98 pounds
The 99% lower confidence bound for the true average weight loss is 3.98 pounds.
This means that we can be 99% sure that the mean weight loss for all obese adults on a low-carb diet is positive.
