Answer:
59 degrees is the answerr
Step-by-step explanation:
Find the area of the 5 sides (not 6 because the top is open).
The area is made up of a load of rectangles. 2 of each rectangle are present except the top and bottom.
(4 x 2 x 2) + (3 x 2 x 2) + (3 x 4) = 40yd²
Answer:
The percent error is 27.27%
Step-by-step explanation:
I did this by using the formula actual-estimated value/actual value
In this case it would be 3.75/13.75 and I got .2727 and then had to multiply by 100 (to find percent not decimal form) and got 27.27%
Answer: 0.8202
Step-by-step explanation:
Probability an adult was never in a museum = probability of success = p = 15% = 0.15
To find probability that 2 or fewer of the 10 samples selected were never in a museum is given by:
P(X=2) or P(X=1) or P(X=0).
Where
P(X=r) = nCr * p^r * q^n-r
and n=10, p =0.15, q=0.85
When r = 2
P(X=2) = 10C2 * 0.15² * 0.85^8 = 0.2759
When r = 1
P(X=1) = 10C1 * 0.15 * 0.85^9 = 0.3474
When r = 0
P(X=0)= 10C0 * 0.15^0 * 0.85^10 = 0.1969
Hence probability of having 2 or fewer adults who never visited the museum = 0.1969 + 0.3474+ 0.2759 = 0.8202
