For a certain urban area, in a random sample of 7 months, an average of 28 mail carriers were bitten by dogs each month. The standard deviation of the sample was 3.5. Find the 99% confidence interval of the true mean number of mail carriers who are bitten by dogs each month. Assume the variable is normally distribute.
a. (29.38)
b. (25, 33)
c. (23,33)
d. (23.35)
Answer:
C
Step-by-step explanation:
Mean = 28
S = 3.5
N = 7
We use the t distribution here.
Level of significance = 99%
Degree of freedom = 7-1 = 6
Using the t table at 99%, and df of 6
T' = t tabulated = 3.7
Confidence interval =[ (mean - t's)/√n , mean + t's)/√n]
= 28-3.7*3.5/√7 , 28+3.7*3.5/√7
= 23.11, 32.89
When approximated
= 23, 33 after rounding to the nearest integer
Therefore option c is the answer

“ Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division”
Answer and equation: If we choose two whole numbers; 8 and 10
We want to divide certain numbers by 8 and 10 to get 9 remainder 5.
In this case; 77 divided by 8 is equal to 9 rem 5
and 95 divided by 10 is equal to 9 rem 5
To justify which is greater, we use decimal division;
= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)
and
= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)
Therefore; the first case is greater since 9.625 is greater than 9.5
That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.
A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (6, -3). What is the vertex of the function defined as
g(x) = f(-x) - 3?
Answer: (-6, - 6)
Step-by-step explanation:
Here we have two transformations, and the first step will be to explain those transformations:
Reflection over the y-axis.
For a function f(x), the reflection over the y-axis is written as:
g(x) = f(-x)
Then if we initially had a point (x, y), the transformed point will be (-x, y).
Vertical translation.
We can define a vertical translation of N units as:
g(x) = f(x) + N
if N > 0, the translation is up.
If N < 0, the translation is down.
Then if we start with a point (x, y), the transformed point will be (x, y + N)
In the case of this problem we have g(x) = f(-x) - 3
This means that N = -3
Then if we initially had the vertex at the point (6, - 3)
The transformed point will be: changing the sign of the x-component and subtracting 3 in the y-component, then the transformed vertex point is:
(-6, -3 - 3) = (-6, - 6)
The vertex of the resulting parabola will be (-6, -6)
Rule of reflectionGiven the function y= f(x), plotted on a graph and the vertex of the resulting
parabola is (6, -3), if this coordinate is reflected over the y-axis, the reflection rule will be:
[tex](x,y) \rightarrow (-x, y)[/tex]The coordinate (6, -3) under this translation will give (-6, -3)To get the corresponding function [tex]g(x) = f(x) - 3\\[/tex]
[tex]g(x) = [(-6, -3) - 3]\\g(x) = (-6, -3-3)\\g(x) =(-6, -6)[/tex]
Hence the vertex of the resulting parabola will be (-6, -6)

Write a linear equation that is parallel to 5x+2y=-8 and passes through the point (8,-9)
Answer:
y= -5/2x+11
Step-by-step explanation:
You want to first reorder the equation into slope intercept form
First subtract 5x from both sides
5x-5x+2y = -8-5x
It should look like:
2y = -5x - 8
Then isolate your y variable
Since the y is multiplied with 2 divide by 2 to isolate and remember to divide the other side as well
It should look like:
2y/2 = -5/2x -8/2
This will result in y = -5/2x - 4
Now since the line is parallel the slope will be the same but to pass through a different point the y intercept will have to change.
Re make your equation and you have:
y = -5/2x + b
Now plug in your (x,y) value for the x and y in the slope intercept form.
-9 = -5/2(8) +b
Now solve for b:
-9 = -40/2 +b
-9 = -20 +b
Isolate your y intercept by adding 20 to both sides
-9 + 20 = -20 + 20 +b
which results with b = 11
Now you have all components to your final slope intercept form giving you the answer
y = -5/2x + 11

Explanation
Rule: The longest side of any triangle is always opposite the largest angle.
Angle T = 98 is the largest angle, so the longest side is SU since it is opposite angle T.

The ratio of boys to girls in a choir is
3 to 8. There are 32 girls in the choir. How many
members are in the choir?
Answer:
there are 12 boys because 32/8 =4 and the ratiots 3 to 8 which means you need to multiply 3 by 4 which gives you 12
Step-by-step explanation:
Answer:
44 members
Step-by-step explanation:
Because to find out the number of members first you have to find out the number of boys in choir
Divide total number of girls (32) by ratio number (8) and you get 4
Multiply the 4 you got by the ratio of boys (3), you get 12 when you multiply these together
Add the total number of boys in choir (12) and number of girls (32) and you get 44 members!

SI ME AYUDAN CON UNA CAPTURA PORFA !
Answer:
A
Step-by-step explanation:
The solution is solved using Equalization methods. Hence the answer to A is such that y= -2 and x = 12
What is the Equalization method?The Equalization method refers to a method whereby a quantity that is unknown in two equations is isolated and equated.
The solution to equation one is thus given below:
[tex]\{ \mathrm{}_{x + 3y = 6}^{2x + 5y = 16}[/tex]
Step I - Isolate any two variables.
In this case, we will isolate x. Hence we will have:
2x + 5y = 16 → x = (16 - 5y)/2 .............................1
x + 3y = 6 → x = (7 - 3y) .............................2
From 1 and 2 above, we can see that both equations are now equal to x, Using the principle of transitivity, we can state that:
Since both formulas are now equal to x, therefore:
(16 - 5y)/2 = (7 - 3y)...............................3
Simplifying and collecting like terms from 3 above, we now have:
(16 - 5y) = 2(7 - 3y)
that is 16 - 5y = 14-6y
This will give us:
6y-5y= 14-16
y = -2
Step II - Substitute Y into any of the original equations to get x.
Recall that we have x + 3y = 6
Therefore, x = 6-3y
That is x = 6-3(-2)
x = 6 + 6 = 12
Hence, for Equation A, x = 12; y = -2
Equation B:
Using the same method, we arrive at: x =45; and y = -3
Equation C:
Using the same method, we arrive at: x = 2; and y = 0

The first 5 terms of a sequence are shown below:
3, -2, -7, -12, -17
Which expression can be used to find the nth term?
Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =
[tex]T_2-T_1 \\ - 2 - 3 \\ = - 5[/tex]
Common ratio =
[tex]T_2/T_1 \\ \frac{ - 2}{3} [/tex]
The common difference applies to the other given numbers for example :
[tex]T_3- T_2 = - 7 - ( - 2) \\ = - 7 + 2 = - 5[/tex]
this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
What would be the correlation between the ages of husbands and wives if men always married woman who were(a) 3 years younger than themselves?(b) 2 years older than themselves?(c) half as old as themselves?
Answer:
the correct answer is a
The correlation between the ages of husbands and wives if men always married woman who were :
(a) 3 years younger than themselves
Correlation occurs as two variables or factors are related, and therefore the change in one variable affects another. In the situation presented there are 2 variables: According to our constitution, the legal age of men is 21 years and 18 years for women is 18 years.So according to the question the correlation between the ages of husbands and wives if men always married woman who will always be 3 years younger than themselves.Therefore, the correct answer is a.

The value of a ratio
Answer:
Students understand the value of a ratio A: B is A/B. ... If two ratios are equivalent, they have the same value. Grade 6, Module 1, Lesson 8: Classwork. Recall that when given a ratio A: B, where B ≠ 0, we call the quotient, A/B, the value of the ratio.
Step-by-step explanation:
For example, the most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.
