Because a quadrilateral has 360 degrees total
Answer:
a) 0.778
b) 0.9222
c) 0.6826
d) 0.3174
e) 2 drivers
Step-by-step explanation:
Given:
Sample size, n = 5
P = 40% = 0.4
a) Probability that none of the drivers shows evidence of intoxication.
b) Probability that at least one of the drivers shows evidence of intoxication would be:
P(X ≥ 1) = 1 - P(X < 1)
c) The probability that at most two of the drivers show evidence of intoxication.
P(x≤2) = P(X = 0) + P(X = 1) + P(X = 2)
d) Probability that more than two of the drivers show evidence of intoxication.
P(x>2) = 1 - P(X ≤ 2)
e) Expected number of intoxicated drivers.
To find this, use:
Sample size multiplied by sample proportion
n * p
= 5 * 0.40
= 2
Expected number of intoxicated drivers would be 2
Answer:
Step-by-step explanation:
5.13 - 4.75 = 0.38
4.75 / 0.38 = 12.5
Answer:
1/8
Step-by-step explanation:
first multiply 2 x 2 and you get 4
then multiply 2x2x2x2x2 and you get 32
simplify 4/32
4 divided by 4 = 1
32 divided by 4 = 8
1/8
I hope this is clear!
10(1/2x+6)=8
Is the equation. Hope this helped!
