The probability would be 0.9738.
We first find the z-score for each end of this interval:
z = (x-μ)/(σ/√n) = (100-110)/(18/√49) = -10/(18/7) = -3.89
z = (x-μ)/(σ/√n) = (115-110)/(18/√49) = 5/(18/7) = 1.94
Using a z-table (http://www.z-table.com) we see that the probability that a score is less than the first z-score is 0. The probability under the curve to the left of, less than, the second z-score is 0.9738. Subtracting these we find the area between them:
0.9738 - 0 = 0.9738.
A = LW
A = 188
W = 4
188 = 4L
188/4 = L
47 = L....so the length is 47 meters
First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi
Next, we are going to use the Pythagorean theorem to find the distance from

to

:


d^2=1665


mi
Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi
We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved
16.2 miles.</span>
Answer:
The required probability is 0.04411
Step-by-step explanation:
The number of female grey mice = 5.
The number of males grey mice = 4.
The number of female white mice = 2.
The number of male white mice = 6.
The number of mice = 17.
The probability of first mice be male grey = 
The probability of second mice be male grey = 
The probability of two mice be male grey =
= 0.04411
Answer:
33 1/3%
Step-by-step explanation:
When you buy 20 ads, the per-ad rate is
$1200/20 = $60 . . . per ad
When you buy 80 ads, the per-ad rate is
$3200/80 = $40 . . . per ad
The percentage change to the $60 price is ...
((new price) - (original price))/(original price) × 100%
= ($40 -$60)/$60 × 100% = -20/60 × 100%
= -1/3 × 100% = -33 1/3%
The higher volume purchase comes with a 33 1/3% discount.
