A random sample of 144 observations has a mean of 20. The population standard deviation is known to equal 4.8. The 95.44% confidence interval for the population mean is
Answer:
The population mean is 19.2 to 20.8.
Step-by-step explanation:
The formula of Confidence interval is
CI = mean ± z*[tex]\frac{s}{\sqrt{n} }[/tex]
where
n = sample size
s = Population standard deviation.
mean = Sample mean
z(α/2) = Two tailed z-value for significance level of .
Given : Confidence level = 95.44% = 0.9544
Significance level = α = 1-0.9544 = 0.0456
Now we Use standard z-value table
z-value for Significance level of 0.0456 :
z(α/2) = z(0.0228) = 1.99 = 2(approximately)
And we are given
n=144
s = 4.8
mean = 20
so the required Confidence interval is
CI = 20± 2*[tex]\frac{4.8}{\sqrt{144} }[/tex]
= 20 ± 2*[tex]\frac{4.8}{12}[/tex]
= 20 ± (0.8)
= (20-0.8, 20+0.8 )
= (19.2 , 20.8)
Therefore the 95.44% CI value for the population mean of 20 is 19.2 to 20.8.

What is the quotient of 480 divided by -60
The quotient when 480 is divided by -60 is 8.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
The numbers given are 480 and -60.
Both are in opposite signs, that is one negative and other positive.
So the quotient will be negative.
Now divide 480 by 60.
Since both of the numbers contain 0 at the end, cancel it.
Then it becomes 48 divided by 6.
48 / 6 = 8
Hence the quotient is 8.

what fraction is equivalent to 1.5/9
Answer:
1.5/9 = 1 1/2 / 9 = 3/2 /9 = 3/18 = 1/6
Step-by-step explanation:
The fraction that is equivalent to 1.5 / 9 is expressed as:
3/18.
How to Find the Equivalent Fraction?Equivalent fractions are different fractions that represent the same value or proportion, although they may have different numerators and denominators.
To find an equivalent fraction for 1.5/9, divide both the numerator and denominator by their greatest common divisor (GCD), which in this case is 0.5.
Dividing 1.5 by 0.5 and 9 by 0.5, we will have the following:
(1.5 ÷ 0.5) / (9 ÷ 0.5) = 3/18
Hence, the equivalent fraction for 1.5/9 is 3/18.

Find the value off(5) for each function
f(h) = - h/10
f(m)=1-4(m/2)
f(m)=2(m-3)
The value of f(5) for each function provided in the reference picture attached hereby with the question statement are as follows:
13. f(5) = 21
14. f(5) = -12
15. f(5) = 20
16. f(5) = (-1/2)
17. f(5) = (-9)
18. f(5) = 4
As per the reference picture attached hereby with the question statement, we are provided with 6 functions.
We are required to find the value of f(5) for each function.
To solve this question, we simply have to replace the the variable of individual functions with 5 and then, perform the operations as per the function to obtain our desired answer.
Starting with [tex][f(x)=6+3x][/tex], substituting (x = 5) in the equation, we will get,
[tex]f(5)=6+(3*5)\\or, f(5)=6+15\\or,f(5)=21[/tex]
Substituting (x = 5) in the second function [tex][f(x)=-2(x+1)][/tex], we get,
[tex]f(5)=-2(5+1)\\or, f(5)=-2(6)\\or,f(5)=-(2*6)\\or, (5)=-12[/tex]
Substituting (x = 5) in the third function [tex]f(a)=[3(a+2)-1][/tex], we get,
[tex]f(5)=[3(5+2)-1]\\or, f(5)=[(3*7)-1]\\or,f(5)=(21-1)\\or,f(5)=20[/tex]
Substituting (x = 5) in the fourth function [tex][f(h)=(\frac{-h}{10})][/tex], we get,
[tex]f(5)=(\frac{-5}{10})\\ or,f(5)=\frac{-1}{2}[/tex]
Substituting (x = 5) in the fifth function [tex]f(m)=[1-4(\frac{m}{10})][/tex], we get,
[tex]f(5)=[1-4(\frac{5}{2})]\\ or,f(5)=[1-(\frac{4*5}{2})]\\ or, f(5)=[1-(2*5)]\\or,f(5)=(1-10)\\or,f(5)=(-9)[/tex]
Finally substituting (x = 5) in the last function [tex]f(m)=[2(m-3)][/tex], we get,
[tex]f(5)=[2(5-3)]\\or,f(5)=(2*2)\\or,f(5)=4[/tex]

A fishing shop charges $8 to rent fishing gear and $35 per hour to rent a boat Write a function to model the cost, y, to rent fishing gear and a boat for x hours.
Answer:
y= 35x + 8
Step-by-step explanation:
the $35 is an hourly charge so it goes with x and the $8 is a one time charge so it just gets added on
The required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
We have been given that a fishing shop charges $8 to rent fishing gear and $35 per hour to rent a boat.
According to the given situation, we can write the function as:
⇒ y = 35x + 8
Here the $35 is an hourly rate, so it corresponds to x, and the $8 is a one-time charge, so it is simply put on.
Therefore, the required function is y = 35x + 8 to model the cost, y, to rent fishing gear and a boat for x hours.
