A population of deer had 200 individuals and 15% were lost in one year. We can calculate the number of deer that were lost with proportion:
200 deer ------------------------100%
x deer ------------------------ 15%
-----------------------------------------------
200 : x = 100 : 15
200 * 15 = 100 x
3,000 = 100 x
x = 3,000 : 100
x = 30
Answer: 30 deer were lost in one year.
Answer: HOPE THIS HELPS YOU! :D
For 13 it’s 1
Step-by-step explanation:
Because the dot on one is the farthest from the rest of the dots.
if the $1 is 75%, then there are 300 of the one dollar prizes
if the $5 is 15%, then there are 60 of the five dollar prizes
so 300 $1 prizes And 60 $5 prizes
360 prizes are either worth $1 or $5
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.
