40.8 because u take 15 percent of 48 and subtract it from 48
7.2 - 48 = 40.8
The answer is c. 0.10. Week 4 is plotted at 0.35 and Week 2 is plotted at 0.25. Difference means subtract. 0.35 - 0.25 = 0.10. Hope this helps!
Answer:
So the answer for this case would be n=247 rounded up to the nearest integer
Step-by-step explanation:
We know that the standard deviation is :
represent the deviation
The margin of error is given by this formula:
(a)
And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be 
, replacing into formula (b) we got:
So the answer for this case would be n=247 rounded up to the nearest integer
Okay. Since we know that the customer before them bought one of each type of bulb, we can subtract one bulb from each type so now, here is what the store has:
5 amaryllis
6 daffodils
3 lilies
2 tulips
Next, let’s find the probability of the customer picking an amaryllis.
We know there are 5 amaryllis, so we can put that as the numerator.
Next, we have to add up all the flowers to get the denominator.
5+6+3+2
I got 16.
So now we have 5/16
So, that is our answer! 5/16, or as a decimal 0.3125, or as a percentage 31.25%.
Hope this helps! Comment if you have any questions! :)
