Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.
The above given is for sample of 27 size.
For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.
But once population std deviation is given, we use only that as that would be more reliable.
So here we can use population std deviation 1.4 only.
If population std deviation is used we can use normality and do Z test

What is Steve's mean speed if he bikes 55.5 miles in 3.7 hours? Round your answer to two decimal places, if necessary.
Answer:
15m/s
Step-by-step explanation:
Given data
DIstance= 55.5 miles
time= 3.7 hours
Required
the speed
We know that
Speed= distance/time
Substitute
Speed= 55.5/3.7
Speed= 15 m/s
Hence the speed is 15m/s
The legs of the drafting table form vertical angles. Find the measures of ∠1, ∠2 and ∠3.
Answer:
m∡1 = 95°
m∡2 = 85°
m∡3 = 95°
Step-by-step explanation:
m∡1 + 85 = 180; m∡1 = 95°
m∡2 = 85° because it is vertical and congruent to the angle measured 85°
m∡3 = m∡1 = 95° because they are vertical and congruent
Answer:
1 = 95, 2 = 85, 3 = 95
Step-by-step explanation:
2 is an opposite angle of 85 degrees so 2 is 85 degrees
a line is always 180 degrees:
1 = 180 - 85 = 95 degrees
1 is an opposite angle of 3 so 3 is also 95 degrees
x^2 – 2x – 54 = 0
I need it in completing the square form
Completing the Square:
x^2 - 2x = 54
x^2 - 2x + 1 = 54 + 1
(x-1)^2 = 55
x - 1 = ±[tex]\sqrt{55\\}[/tex]
x = 1 ± [tex]\sqrt{55}[/tex]

What is a Fraction?In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.
As per the given data:
Brownies in each box = 15
Boxes handed out = 1 [tex]\frac45[/tex]
Brownies with nuts = (1/9) of the brownies
Boxes handed out = 1 [tex]\frac45[/tex] = (9/5) boxes
Total brownies handed out = (9/5) × 15 = 27 brownies
Total brownies with nuts = (1/9) of 27 = (27/9) = 3 brownies with nuts.
Hence, 3 brownies had nuts.

Answer:
(11+x)-3
Step-by-step explanation:
11 more than x is another way of saying 11+x
And "less than 3" means subtracting 3 from the terms
So if you put that together it would be
(11+x) -3

Answer:

Step-by-step explanation:
On a large college campus, the students are able to get free copies of the school newspaper,the local newspaper, and a national paper. Ninety percent of the students read at least one of thepapers, 40% read only the school newspaper, 20% read only the local paper, 5% read only thenational paper, and 2% read all three papers. Fifty percent read the school newspaper, and 5%read the school and national newspapers. A randomly selected student is asked whether he orshe reads the school, local, or national paper. Express each of the following events in setnotation and find the percentage of students represented by each.a The student does not read any paper.b. The student reads the local paper.c. The student reads exactly two papers.d. The student reads at least two papers.
Answer:
a) The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper is 40%
c) the percentage that the student reads exactly two papers is 23%
d) the percentage that the student reads at least two papers is 25%
Step-by-step explanation:
Given the data in the question;
as illustrated in the Venn diagram below,
a)The student does not read any paper;
The percentage that the student does not read any paper will be;
100% - 90% = 10%
Therefore, The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper;
from the Venn diagram below;
⇒ ( 20 + 15 + 3 + 2 )%
= 40%
Therefore, The percentage that the student reads the local paper is 40%
c) The percentage that the student reads exactly two papers
⇒ ( 15 + 5 + 3 )%
= 23%
Therefore, the percentage that the student reads exactly two papers is 23%
d) The percentage that the student reads at least two papers;
⇒( 15 + 5 + 3 + 2 )%
= 25%
Therefore, the percentage that the student reads at least two papers is 25%
A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?
Answer:
The equation is: [tex]f(x) = 52000 - 8000x[/tex]
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.
[tex]Amount = Initial - Rate* Years[/tex]
We used minus (-) because, the amount reduces as the student pays.
Let
[tex]y = Amount[/tex]
[tex]x = Years[/tex]
So, we have:
[tex]y = Initial - Rate * x[/tex]
Substitute values for Initial and Rate
[tex]y = 52000 - 8000 * x[/tex]
[tex]y = 52000 - 8000x[/tex]
Express as a function:
[tex]f(x) = 52000 - 8000x[/tex]
