14. A cellular telephone company recently conducted research into the length of calls (in
minutes) made by customers. In a random sample of 30 calls, the sample mean was
x= 18.6 minutes and the standard deviation was s=5.2 minutes. Construct and interpret
a 90% confidence interval for true mean call length. (4-step process)
Answer:
The correct answer is "16.987, 20213".
Step-by-step explanation:
Given that,
[tex]n=30[/tex]
[tex]\bar x=18.6[/tex]
[tex]s = 5.2[/tex]
[tex]df=30-1[/tex]
[tex]=29[/tex]
[tex]\alpha = 0.10[/tex]
By using the table, the critical values of t will be:
= [tex]\pm 1.699[/tex]
Now,
The confidence interval will be:
= [tex]\bar x \pm \frac{t\times s}{\sqrt{n} }[/tex]
By putting the values, we get
= [tex]18.6 \pm \frac{1.699\times 5.2}{\sqrt{30} }[/tex]
= [tex]16.987,20.213[/tex]
Q. Find missing angle
Answer:
c =√a2 + b2=√152 + 122=√369=19.20937
∠α =arcsin(a)c= arcsin(15)19.209372712299=arcsin(0.78086880944303) = 51.34° = 51
answer is C
Answer:
Tan x = opp/ adj
Tan x = 15 / 12
Tan x = 1.25
Angle = 51.34
C. 51 degrees

Find the value of g in the figure given below.
Assume that the lines are parallel.
Answer:
d=60-degree (Vertically opposite angles)
e=d=60-degree (Alternate angles)
e+g=180-degree (Being in a straight line)
60+g=180
g=180-60
g=120-degree
Answer:
angle g = 20 degree
Step-by-step explanation:
60 degree + angle g = 180 degree (being co exterior angles)
angle g = 180 - 60
angle g = 120 degree
Note : co interior angles are the angles formed on the exterior of the two parallel lines and which are on the same side of the transversal .
129x-33=112
solve for x
Answer:
x =145/129
Step-by-step explanation:
129x-33=112
Add 33 to each side
129x-33+33=112+33
129x = 145
Divide each side by 129
129x/129 = 145/129
x =145/129

Question 10 of 10 Classify the following triangle. Check all that apply. 7 A. Right B. Acute C. Isosceles D. Scalene E. Equilateral F. Obtuse
D & F
Step-by-step explanation:
D scale because all sides are different lengths
F obtuse because one angle is greater than 90 degrees
Look up definition of the other properties and you will see they don't apply
The given triangle is a obtuse and scalene triangle
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The given triangle is an obtuse triangle and scalene triangle.
A triangle whose any one of the angles is an obtuse angle or more than 90° is known as obtuse triangle.
A triangle in which all the three sides have different lengths then it is called as scalene triangle.
Hence, the given triangle is a obtuse and scalene triangle.

I NEED HELP WITH THESE TWO QUESTIONS ASAP PLEASE!!!
Answer:
6. (2,1) 7. (2,2)
Step-by-step explanation:
Number 6, Since it is a dilation of .5 you divide the x and y coordinate by 2 to get (2,1). X - 4/2=2, Y - 2/2=1
Number 7, Since it's rotating 90 degrees counterclockwise you switch the x and y coordinates. So from (x,y) to (y,x) and also when going counterclockwise you have to make the y coordinate becomes negative, so the counterclockwise equation is (-y,x) plug in your numbers and you get (2,2) as your 90 degree counterclockwise rotated coordinates.

What is m angle KNL?
Enter your answer in the box.
Answer:
KNL = 102
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
5x+2 = 3(x+14)
5x+2 = 3x+42
Subtract 3x from each side
5x-3x+2 = 3x+42-3x
2x+2 = 42
Subtract 2 from each side
2x+2-2 = 42-2
2x = 40
Divide by 2
2x/2 = 40/2
x = 20
We want to find KNL
KNL = 3(x+14) = 3(20+14) = 3 ( 34) = 102

Answer:
I'm not sure what you are looking for but I'm assuming you are finding r.
r is equal to 4.
Step-by-step explanation:
6 = r + 2
In order to find r, you have to subtract 2 from 6.
So, r = 6 - 2 = 4
