(3x + 1) + (4x - 17) + (5x - 20) = 180
12x - 36 = 180
12x = 216
x = 18
angle a = 55
angle b = 55
angle c = 70
This is an acute isosceles triangle.
14 / 1.8 = 7.77777778
about 7.77777778 miles
but it depends on what the initail fee is
Answer:
<h3>
The mean is 3.74</h3>
Step-by-step explanation:
Answer:
9.9
Step-by-step explanation:
The table tells you numbers who "want" a job. The question asks you for numbers "looking for a job". Those may be different things. The question cannot be answered from the table, unless you make the assumption that those wanting a job are actually looking for a job.
total looking = (working and looking) + (not working and looking)
= 5.2 million + 4.7 million
= 9.9 million . . . . looking for a job
Answer:
The 99% confidence interval for the mean amount of money spent on lunch per week for all college students is between $41.40 and $44.60.
Step-by-step explanation:
A confidence interval has two bounds, a lower bounds and an upper bound.
These bounds depend on the sample mean and the margin of error.
The lower bound is the sample mean subtracted by the margin of error.
The upper bound is the margin of error added to the sample mean.
In this problem, we have that:
The sample mean is $43.
The margin of error is $1.60 for a 99% confidence interval.
Lower bound: 43 - 1.60 = $41.40
Upper bound: 43 + 1.60 = $44.60
The 99% confidence interval for the mean amount of money spent on lunch per week for all college students is between $41.40 and $44.60.
