Answer:
Probability both are nervous around strangers = 0.0049
Probability at least one is nervous around strangers = 0.1302
Step-by-step explanation:
Let probability a person selected in the population is nervous around strangers = P
P = 7%
P =
P = 0.07
Let probability a person selected in the population is not nervous around strangers = P'
P' = 1 - P
P' = 1 - 0.07
P' = 0.93
(i) probability of the first person selected is nervous around strangers = P
probability of the second person selected is nervous around strangers = P
Probability both are nervous around strangers = (P × P)
= 0.07 × 0.07
= 0.0049
(ii) Probability at least one is nervous around strangers = ( probability the first person is nervous around strangers AND the second person is not nervous around strangers ) OR ( probability the second person is nervous around strangers AND the first person is not nervous around strangers)
This implies,
Probability at least one is nervous around strangers = (P × P') or (P × P')
= (0.07 × 0.93) + (0.07 × 0.93)
= 0.0651 + 0.0651
= 0.1302
Answer:
72
Step-by-step explanation:
number of children tickets purchased = c
number of adult tickets purchased = a
c+a= 164
(5.10 x c) + (9.40 x a) = 1232
c + a - a = 164 - a
c = 164 -a
(5.10 x (164-a)) + (9.40 x a) = 1232
836.40 - 5.10a + 9.40a = 1232
836.40 + 4.30a = 1232
4.30a = 395.60
4.30a/4.30 = 395.60/4.30
a = 92
c = 164 - 92
c = 72
Answer:
Oil is not renewable because it uses fossil fuels from dinos, which do not exist anymore, so they are limited
Step-by-step explanation:
Answer:
1111
Step-by-step explanation:
808/8=101
101x11=1111
Adults: $22
Children: $22 - $5 = $17
22a + 17c = t
22(12) + 17(15) = t
264 + 255 = $519
The total cost of admission is $519.
Hope this helped!
