Answer:
a) 0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.
b) 0.996 is the probability that more than half of the vehicles carry just one person.
Step-by-step explanation:
We are given the following information:
A) Binomial distribution
We treat vehicle on road with one passenger as a success.
P(success) = 64% = 0.64
Then the number of vehicles follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 10
We have to evaluate:
0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.
B) By normal approximation
Sample size, n = 92
p = 0.64
We have to evaluate the probability that more than 47 cars carry just one person.
After continuity correction, we will evaluate
Calculation the value from standard normal z table, we have,
0.996 is the probability that more than half out of 92 vehicles carry just one person.
Answer:
from the picture the answer is D.
Step-by-step explanation:
to find x subtract 18x from 4x which will give you -14x=-36
divide both sides by -14
3) y = x + 3
Slope-intercept form is y = mx + b when m is the slope and b is the y-intercept
b = 2 (line hits y-axis at 2)
m = so
and the line is negative, so
Write our equation by putting the parts together, and we get:
y = x + 3
4) y = x - 1.67
Point slope form is y - y1 = m (x - x1) when y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate of the point
y - y1 = m (x - x1)
Finding the slope (same as above) results in
