Answer:
747ft
Step-by-step explanation:
split the shape into two rectangles. First one has length of 25 and has width of 10 because 20ft plus the 10ft ill give you the whole 30ft at the top. Multiply 25 by 10. So area for first shape is 250ft. Second shape area is 497 because you multiply 7 by 20. Then add 497 and 250 you get 747.
Answer:
Im pretty sure its 0.2
Step-by-step explanation:
Answer: 44% of the students are boys.
Step-by-step explanation:
We know the total number of students is 25 and the total number of boys is 11 so you divide 11 by 25 then multiply by 100 to get the percentage. Ex. 11/25=0.44 0.44 x 100= 44. Answer 44%
Answer:
(a)
The expected number in the sample that treats hazardous waste on-site is 0.383.
(b)
There is a 0.000169 probability that 4 of the 10 selected facilities treat hazardous waste on-site.
Step-by-step explanation:
Professional Geographer (Feb. 2000) reported the hazardous waste generation and disposal characteristics of 209 facilities.
N = 209
Only eight of these facilities treated hazardous waste on-site.
r = 8
a. In a random sample of 10 of the 209 facilities, what is the expected number in the sample that treats hazardous waste on-site?
n = 10
The expected number in the sample that treats hazardous waste on-site is given by
Therefore, the expected number in the sample that treats hazardous waste on-site is 0.383.
b. Find the probability that 4 of the 10 selected facilities treat hazardous waste on-site
The probability is given by
For the given case, we have
N = 209
n = 10
r = 8
x = 4
Therefore, there is a 0.000169 probability that 4 of the 10 selected facilities treat hazardous waste on-site.
Start with $7.25 x 10= $ 72.50
105.50-72.50= 37.00 leftover after admission paid
37.00/5.50= 6 ride passes with some money left over
So 6 got ride passes
