Answer:
0.183
Step-by-step explanation:
This is a question on Binomial Probability
Formula =nCx × p^x × q^n - x
p = 0.72
q = 1 - p
= 1 - 0.72
= 0.28
x = number of successes = 9
n = 10
The probability that at least nine out of ten people used an online travel website when they booked their airline ticket
At least 9 out of 10 means
x ≥ 9 = x = 9 and x = 10
Hence,
P(x ≥ 9) = 10C9 × (0.72^9 × 0.28^10 - 9) + 10C10 × ( 0.72^10 × 0.28^10 - 10)
P(x ≥ 9) = 0.14559635388 + 0.0374390623
= 0.18303541631
≈ 0.183
<em><u>Answer:</u></em>
Around 4 : 3 because the measurements might not be perfect.
<em><u>Step-by-step explanation:</u></em>
So the ratio of the NEW : ORIGINAL is just one side of the rectangle to the other side of the original one.
We know that the newer rectangle (or the larger one) has 4 cm as its side and that the original one (the smaller one) has 3cm as its side. Then we can create the ratio of NEW : ORIGINAL as: 4 : 3
This question is basically a ratio 1 : 42
so then it would be 2 : 84 then 3 : 126
So your answer is D 3 Gallons for 126 miles.

Answer:
x=58
Step-by-step explanation: Since there is a right angle, you add 22 and 10 and get 32. then you subtract from 90, because 90 degrees is what a right angle measures so you should get 58
