Answer:
Step-by-step explanation:
A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 108, and the sample standard deviation, s, is found to be 10. (a) Construct a 96% confidence interval about μ if the sample size, n, is 17. (b) Construct a 96% confidence interval about μ if the sample size, n, is 12. (c) Construct a 90% confidence interval about μ if the sample size, n, is 17. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
Plzzzz help ASAP. What is an equation of the line that passes through the point (1,6) and is perpendicular to the line x+3y=27
Answer:
y = 3x + 3
Step-by-step explanation:
x + 3y = 27
3y = -x + 27
y = [tex]\frac{-1}{3}x +\frac{27}{3}[/tex]
y = [tex]\frac{-1}{3}x + 9[/tex]
m₁ = -1/3
the slope of the line perpendicular to x + 3y = 27 is m₂ = -1/m₁
m₂ = [tex]-1 * \frac{-3}{1}[/tex] = 3 , Point (1 , 6)
y - y1 = m (x -x1)
y -6 = 3(x - 1)
y - 6= 3x - 3
y = 3x - 3 +6
y = 3x + 3
Answer:
3x-y=27
Step-by-step explanation:
perpendicular is making a 90 degree angle, so it would need to be a slope of 3 if the other is -1/3.
y=9, x=27
3x-y=27 is the polar opposite, and should work, sorry if wrong. hard to do in my head without a graph to help.

Step-by-step explanation:
HOW DO YOU EVALUATE
(To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.)

f(6) means that you look at x = 6 and notice the y-axis, then you will get the answer.
If you don't know. f(6) = -6 (Look at x = 6 then look at y = -6.)
Also for g(5), same with f(6). Look at x = 5 and notice the y-axis. When x = 5, y = -5.
Now we know that f(6) = -6 and g(5) = -5
Substitute f(6) = -6 and g(5) = -5 for easier look.
[tex]-6-6*(-5) = -6+30 = 24[/tex]
So the answer is 24.
What's the slope? Help plssss
Answer:

If 4(r+2)-13=11, what is the value of r ?
Answer:
r=4
Step-by-step explanation:
First you multiply 4 by r which gives you 4r. Then you multiply 4 by 2 to give you 8.So it looks like this now
4r+8-13=11
Now you add thirteen to both sides and get
4r+8= 24
Then you subtract both sides by 8 to get 16
4r=16
Then you divide both sides by 4 to get 4
r=4
The value of r for equation 4(r+2)-13=11 is 4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
4(r+2)-13=11,
Add 13 in both the sides,
4(r+2)-13+13=11+13,
4(r+2) + 0 = 24
4(r+2) = 24
Divide by 4 both sides,
r+2 = 6
r= 4
The value of r is 4.

Find the area of the shape shown below.
Answer:
32 units²
Step-by-step explanation:
Area of trapezoid = [tex]\frac{b_{1} +b_{2} }{2} h[/tex]
A = [tex]\frac{4+12}{2} 4[/tex] = 32 units²
Answer:
The area of the trapezoid is 32 units squared
Step-by-step explanation:
You can use the formula A = [tex]\frac{a + B}{2} *h[/tex] to find the area of a trapezoid.
In this case a = 4, B = 12, and h = 4. Plug the numbers into the formula and you will get 32.

In the diagram triangle XYZ is congruent or equal to triangle MNL. Copy and complete the statement.
Answer:
5. 124 degrees
6. 23
7. 8
8. LN with a line over the top
9. Triangle symbol ZYX
10.Triangle symbol NML
Step-by-step explanation:
5. You are working with congruences. Therefore, for #5 it is asking about the angle Y. Look at the diagrams. Angle Y is congruent with angle N therefore your answer is 124 degrees.
6. In 6 they want to know what angle M is. Well, you already know that the interior of a triangle is 180 therefore, you would subtract 180-124=56. You then subtract angle L which is the same as angle X and therefore is 33. 56-33=23. So angle M is 23.
7. For 7 they want to know what the line YX is. Again, we are working with congruences and therefore line YX is the same as line NM so the answer is
8. In 8, the want to know what the line YZ is equal to. Working with congruences, you know that line YZ=LN. Make sure you put the line over LN as they did with YZ.
9.Working with congruencies, they want to know what triangle LNM is equal to. Looking at the diagram, you know that since they are congruent, triangle LNM is equal to triangle ZYX. Make sure you use the triangle symbol.
10. Again, they what to know what the triangle is equal to. Look at your diagram. Line YX is equal to line NM. Line XZ is equal to line ML. Line ZY is equal to line LN. to triangle YXZ is equal to triangle NML. I think they just want you to put the letters in the corresponding order.
I hope these are correct and that this helps you.
