Answer:C. 38.14
Step-by-step explanation:
The required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.
Given that,
The number of hours the employee worked each week for seven consecutive weeks was 38, 37. 5, 38. 25, 35. 75, 39. 5, 39. 5, and 38. 5.
The mean of the values is the ratio of the total sum of values to the number of values.
here,
According to the question,
Mean = Sum of the working hours/number of weeks
Mean = 38 + 37. 5 + 38. 25 + 35. 75 + 39. 5 + 39. 5 + 38. 5 / 7
Mean = 267/7
Mean = 38.14
Thus, the required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Consider this dilation.
Hint: Remember the notation for the original figure and the figure after it has undergone transformation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain and show your work.
Answer:
(a) Reduction
(b) scale factor = 1/2
Step-by-step explanation:
(a) A reduction is a dilation that creates a smaller image.
As A'B'C'D' is smaller than ABCD, image A'B'C'D' is a reduction of image ABCD.
(b) To find the scale factor:
find the center of dilation by connecting the corresponding points from the original and dilated image and finding where these lines intersect (see attached image)measure from the center of dilation to a point on the original image.measure from the center of dilation to the corresponding point on the dilated image.Divide the distance to the dilated image by the distance to the original image.center of dilation = (0, 0)
(0, 0) to point C = 4 units
(0, 0) to point C' = 2 units
⇒ scale factor = 2/4 = 1/2

Hint:
Rewrite 3x − (7 − x) as
3x + −1(7 − x)
and then use the Distributive Property to simplify.
6x = 45
6x = 60
6x = 46
6x = 54
Answer:
54
Step-by-step explanation:
3x -(7-x) = 29 remove the parens
3x - 7 + x = 29 simplify
4x -7 = 29 add 7 to both sides of the equation
4x = 36 divide by

The probability of a customer purchase popcorn at the movie theater is 0.3. What is the probability that a customer will not purchase popcorn
Reason:
There's a 30% chance they buy the popcorn, which means there's a 70% chance they don't buy it.
100% - 30% = 70%
Then convert the 70% to 0.7
Answer:
0.7 or 70%
Step-by-step explanation:
0.3 * 100 = 30%
100%-30% = 70%
You either buy or not. If 30% you don't then 70% you do.

Urgent. There are 12 coloured counters in a bag. The counters are black, white or grey A counter is chosen at random. The probability that the counter is not black is 3/4. The probability that the counter is not white is 2/3. Work out the probability that the counter is grey.
Answer:
1/12
Step-by-step explanation:
Needed information
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
The sum of the probabilities of all outcomes must equal 1
Solution
We are told that the probability that the counter is not black is 3/4.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is black by subtracting 3/4 from 1:
[tex]\sf P(counter\:not\:black)=\dfrac34[/tex]
[tex]\implies \sf P(counter\:black)=1-\dfrac34=\dfrac14[/tex]
We are told that the probability that the counter is not white is 2/3.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is white by subtracting 2/3 from 1:
[tex]\sf P(counter\:not\:white)=\dfrac23[/tex]
[tex]\implies \sf P(counter\:white)=1-\dfrac23=\dfrac13[/tex]
We are told that there are black, white and grey counters in the bag. We also know that the sum of the probabilities of all outcomes must equal 1. Therefore, we can work out the probability the counter is grey by subtracting the probability the counter is black and the probability the counter is white from 1:
[tex]\begin{aligned}\sf P(counter\:grey) & = \sf1-P(counter\:black)-P(counter\:white)\\\\ & =\sf 1-\dfrac14-\dfrac13\\\\ & = \sf \dfrac{12}{12}-\dfrac{3}{12}-\dfrac{4}{12}\\\\ & = \sf \dfrac{12-3-4}{12}\\\\ & = \sf \dfrac{5}{12}\end{aligned}[/tex]

Answer:
x = 5
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
21x + 5 is an exterior angle of the triangle , then
21x + 5 = 5 + 13x + 40
21x + 5 = 13x + 45 ( subtract 13x from both sides )
8x + 5 = 45 ( subtract 5 from both sides )
8x = 40 ( divide both sides by 8 )
x = 5
Answer:
x=5
Step-by-step explanation:
Angles Q and R are supplementary
13x + 21x +5 = 180
10+34x =180
34x=170
x = 5
Given circle O with diameter AB find x
A circle is a curve sketched out by a point moving in a plane. The measure of x is 60°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given that the measure of the arc AC is 120°. Now, as we know, the diameter divides the circle into two equal chords of 180° each. Therefore, the measure of x can be written as,
[tex]x = {\rm arcAB-arc AC}\\\\x = 180^o-120^o\\\\x = 60^o[/tex]
Hence, the measure of x is 60°.
