Answer:
0.001709
Step-by-step explanation:
The probability of getting 9 tails then 1 head is:
(½)⁹ (½)¹ = (½)¹⁰
The probability of getting 10 tails then 1 head is:
(½)¹⁰ (½)¹ = (½)¹¹
The probability of getting 11 tails then 1 head is:
(½)¹¹ (½)¹ = (½)¹²
The total probability is:
(½)¹⁰ + (½)¹¹ + (½)¹²
0.001709
Answer:
0.2m+37≤95
Step-by-step explanation:
I don't understand the last part of the question, but I do know the inequality if that helps. in the inequality 0.2m+37≤ 95, m is the variable that represents the miles driven.
Answer:
D&B
Step-by-step explanation:
turn 6 to a fraction which is 6/1
So you keep the first fraction the same
change the division sign to a multiplication sign
change 3/4 to 4/3
so 6/1x4/3
multiply straight across the top and bottom
you get 24/3
simplified is 1/8lbs
Answer:
d. The width of Elly's interval will be less than the width of Drew's interval.
Step-by-step explanation:
The confidence level and the width of the confidence interval are direct proportional. This means that a confidence interval with a higher confidence level has a higher width.
For example, a 99 percent confidence interval is wider than a 90 percent confidence interval.
The midpoint of the confidence interval is the mean of the population, no matter the confidence level.
In this problem, we have that:
Elly: 90 percent CI
Drew: 99 percent CI
The correct answer is:
d. The width of Elly's interval will be less than the width of Drew's interval.
Answer:
x=0, y=0
x=8, y=4
Step-by-step explanation:
y= 1/2x
y=1/2(0)
y=0
y=1/2x
y=1/2(8)
y=4
