Answer:
0%
Step-by-step explanation:
We have the following information:
mean (m) = 208 days
standard deviation (s) = 15 days
We have that the z value would be:
z = (x - m) / sd
replacing we have:
z = (308 - 208) / 15
z = 6.66
However,
P (x> 308) = 1 - (x <308)
P (x> 308) = 1 - (z <6.66)
if we look for this value of z in the table we assume that it is 1, since the table reaches 3 and the value is 1. Therefore:
P (x> 308) = 1 - 1
P (x> 308) = 0
Which means that the probability is 0%, therefore it is a very unusual pregnancy.
Answer:
D. Swordfish treat: 20%
Lizard Lollies : 50%
Puffer pops: 30%.
Step-by-step explanation:
We are told that Matrix is handing out treats at a local protest to promote his new detective agency.
Since he replaces the chosen treat each time with the same treat, so number of each treat remains same and it will not affect the probability for next person to choose the treat.
We know that 
.
Let us find probability of choosing each type of treat one by one.
Therefore, the probability of choosing swordfish treat is 0.20 or 20%.
Therefore, the probability of choosing lizard Lollies is 0.50 or 50%.
Therefore, the probability of choosing puffer pops treat is 0.30 or 30%.
Upon looking at our given choices we can see that option D is the correct choice.
Yes that’s correct. I’m doing flvs too!
Unsure of what you want here. If you want the square of 3 3/8, convert
3 3/8 to 27/8 and square that improper fraction: (27/8)^2 = 729/64.
And so on.
The cube of 3 3/8 is (27/8)^3 = 19683/512. You could also write that as 38.44 (which has been rounded off).
Answer:
2534.4 revolutions
Step-by-step explanation:
There's 63360 inches in a mile. Divide that by 25, which is the revolutions and that equals <em>2534.4 revolutions</em>.
