Answer:
The 95% confidence interval for the population mean is between $140.89 and $159.11.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{36}{\sqrt{150}} = 9.11[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 150 - 9.11 = $140.89
The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11
The 95% confidence interval for the population mean is between $140.89 and $159.11.

April is making necklaces using beads
that are 6 millimeters in diameter.
What is the diameter of each bead in
centimeters?
Step-by-step explanation:
To convert millimeters to centimeters we divide
As, 10 millimeters = 1 centimeter
So 1 centimeter = 1/10 millimeter
So here of we have 6 millimeters, so centimeters = 6/10 = 0.6cm
So the diameter of each bead in the necklace = 0.6cm
The diameter of bead in a necklaces is 0.6 centimeters.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Given that, April is making necklaces using beads that are 6 millimeters in diameter.
We know that, both millimeters and centimeters is the unit to measure the length. One millimeter is equal to 0.1 centimeters and 1 cm is equal to 10 mm.
Here, 6 millimeters
= 6×0.1
= 0.6 centimeters
Therefore, the diameter of a bead is 0.6 centimeters.

hope this helps!!:)
Step-by-step explanation:
Let us denote by P the set of all people, by S the set of people who are single, by C the set of people who have children, by W the set of women and by M the set of men. For each question below, write down an expression that represents the set being described. Write exactly one expression for each question.
a. Women who are either married with children, or single and do not have children.
b. All possible married heterosexual couples, i.e., all possible pairings of married men and married women.
c. The number of all possible married heterosexual couples.
Solution :
Given :
The events are as follows :
P : Set of all the people
S : Set of people those who are single
C : Set of people having children
W : Set of women
M : Set of men
a). Now set of married women having children is given by :
[tex]$\left( (P-S)-M \right) \cap C $[/tex]
And set of single women who do not have any children : (S -C) - M
Thus the set of women those who are either married and have children or they are single and they do not have any children is represented by :
[tex]$\left( (S-C)-M\right) \cup \left( ((P-S)-M) \cap C \right) $[/tex]
b). Set of Married men : [tex]$\left( (P-S) \cap M$[/tex]
Set of Married men : [tex]$\left( (P-S) \cap W$[/tex]
Set of all possible married who are heterosexual couples, that is, all possible pairings of the married men and the married women is represented by :
[tex]$((P-S) \cap M) \cap ((P-S) \cap W )$[/tex]
c). The number of all the possible married heterosexual couples will be represented by the cardinality of the above set, which represents the number of the elements in the set.
Thus the number of the married heterosexual couples is given by :
[tex]$n[((P-S) \cap M) \cap ((P-S) \cap W)]$[/tex]
If f(x)= x/2-2 and g(x)= 2x^2+x-3, find (f+g)(x).
Answer:
2x^{2} + \frac{3}{2} x - 5
Step-by-step explanation:
(f+g)(x) = f(x)+g(x)
(f+g)(x)= [tex]\frac{x}{2} -2[/tex] + [tex]2x^{2} +x-3[/tex] = [tex]2x^{2} + \frac{3}{2} x - 5[/tex]

Use shifts and scalings to graph the given function. The
p(x)= x² + 2x - 6
What is the original function?
y =
(Type an expression. Simplify your answer.)
Answer:
x^2+2x
Step-by-step explanation:
This function was shifted down 6 units.
It does not seem like this function was shifted horizontally since the x value is not being subtracted nor added inside the parentheses. Therefore, the original function would just be p(x) + 6, which would give us x^2+2x.
