Which shape has only one pair of parallel sides?
Answer:
The answer is C.
Step-by-step explanation:
This is because that shape only has the top and bottom lines which are parallel. The sides are not vertical and leaning outwards, which are not parallel. Leaving that shape to only have one pair of parallel sides.
Answer:
C.
Step-by-step explanation:
A & B both have 2 pairs of parallel lines, so they're not a choice. D has three sides, making it a triangle. Meaning it has no pairs of parallel lines. That leaves us with C. The reason why C is the answer is because, we can see that both top and bottom lines are parallel to each other. However, the left and right lines are not.

In the first week of Georgia's job, she earned $125.25 for working 15 hours. During her second week, she earned $167.00 for working
20 hours. How much does she earn in dollars for each hour she works?
Answer:
Georgia earns $8.35 per hour
Step-by-step explanation:
$125.25 / 15 hours = $8.35
$167.00 / 20 hours = $8.35
You can also find how much Georgia makes an hour by:
15 hours + 20 hours = $125.25 + $167.00
OR...
15x + 20x = $125.25 +$167.00
35x = $292.25
x = $292.25 / 35
x = $8.35 earned per hour

Answer:
1) 1/2, 2) 2Step-by-step explanation:
#1Number of total outcomes is 12 (numbers 1 through 12)Favorable outcomes are 2, 3, 7, 10, total number is 4Unfavorable outcomes are the rest of numbers, total number is 8The 'odds' is
Odds for (2, 3, 7, 10) = 4/8 = 1/2#2Number of total outcomes is 12 Number of favorable outcomes is 4 (numbers less than 5)Number of unfovorable outcomes is 8 (the rest of numbers)The 'odds against' is
Odds against (< 5) = 8/4 = 2/1 or 2Answer:
Question 1"Odds for" - Number of successes : Number of failures
Number of success = 2, 3, 7 or 10
Number of failures = 1, 4, 5, 6, 8, 9, 11, 12
⇒ odds for stopping on 2, 3, 7 or 10 = 4/8 = 1/2
Question 2"Odds against" - Number of failures : Number of successes
Number of success = 1, 2, 3, 4
Number of failures = 5, 6, 7, 8, 9, 10, 11, 12
⇒ odds against stopping on 1, 2, 3 or 4 = 8/4 = 2

The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of 8.9 cm.
a. Find the probability that an individual distance is greater than 212.50 cm
b. Find the probability that the mean for 25 randomly selected distances is greater than 201.00 cm
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
a. The probability is
(Round to four decimal places as needed)
b. The probability is I
(Round to four decimal places as needed.)
c. Choose the correct answer below.
O A The normal distribution can be used because the mean is large.
B. The normal distribution can be used because the finite population correction factor is small.
OC. The normal distribution can be used because the probability is less than 0.5
OD. The normal distribution can be used because the original population has a normal distribution
Answer:
I am not sure if you're accustomed to using a z-score and table of probabilities or technology, so I will answer using both!
a) Since you're choosing one person from the population, you will use the mean and standard deviation from the population. z= (210.9-197.5)/8.6 = 1.56 Using a table of normal probabilities,
P(x>210.9)= 1-P(z<1.56)= 1- 0.9406=0.0594
Using technology: normalcdf(210.9, 1E99, 197.5, 8.6)=0.0596
b) Since you're calculating the population for a sample to occur, you need to get a mean of the sampling distribution and standard deviation of the sampling distribution.
Meanpop=Meansampling dist.=197.5
St. Devsampling dist.= Stdpopulation/√n = 8.6/√15 = 2.22
Using technology, P(X>196.20)= normalcdf( 196.20, 1E99, 197.5, 2.22) = 0.7209
c) You only have to worry about the sample size in a sampling distribution if you either do not know the shape of the distribution of the population or if the distribution of the population is not normally distributed. Since this population is normally distributed (as stated in the given information), then your sample size does not have to be greater than 30.

Fiona is paid $11 an hour to work as a referee. The amount of money he earns depends on how many hours he works. Which is a dependent variable, and which is an independent variable?
Answer:
Number of hours worked = independent
Money earned = dependent
Step-by-step explanation:
The money earned is dependent because "the amount of money he earns depends on how many hours he works." Since the money earned is dependent, the number of hours worked is independent.
We can also think of it another way. You can pick how many hours you work (theoretically) so this is indepdent. The amount of money earned depends on the hours you worked.
Summary:
Looking at the wording, we can answer the question with the following:
Number of hours worked = independent
Money earned = dependent
A company is going to make a storage container with sheet steel walls. The container will be in the shape of a rectangular prism, as shown below. If the sheet steel costs $20 for each square meter, how much will the sheet steel cost in total?
Answer :-
The value of all the steel sheet is $2080
Solving steps:-
⇢ A=2(wl+hl+hw)
Where,
Length = 6mWidth or breath = 5mHeight = 2m⇢ A = 2((5)(6)+(2)(6)+(2)(5))

Write an expression to represent the area of each figure
Answer:
A = 4x² + 3x - 1
Step-by-step explanation:
Area of trapezoid = (a + b)(h)/2
a = 5x - 4b = 3x + 2h = x + 1A = [((5x - 4) + (3x + 2)) · (x + 1)] ÷ 2
A = [(8x - 2) · (x + 1)] ÷ 2
A = (8x² + 8x - 2x - 2) ÷ 2
A = 4x² + 4x - x - 1
A = 4x² + 3x - 1
Hope this helps and God bless!
To setup an equation for the area of the figure:
⇒ must know the formula for the area of a trapezoid
[tex]\frac{1}{2}*(base1+base2)*height[/tex]
base 1 --> 5x - 4base 2 --> 3x + 2height --> x + 1Now's lets set up the equation:
[tex]Area =\frac{1}{2}(5x-4+3x+2)(x+1) =\frac{1}{2}(8x-2)(x+1)=\frac{1}{2}*(8x^2+8x-2x-2)\\Area = \frac{1}{2} *(8x^2+6x-2)\\Area = 4x^2+3x-1[/tex]
Thus the equation is [tex]4x^2+3x-1[/tex]
Answer: [tex]4x^2+3x-1[/tex]
Hope that helps!

It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away. During the return journey, it took him 15 hours. Assume the pack ice was drifting at a constant rate, and that Fred’s snowmobile was traveling at a constant speed relative to the pack ice. What was the speed of Fred’s snowmobile?
Using the relation between velocity, distance and time, it is found that the speed of Fred’s snowmobile was of 27 miles per hour.
What is the relation between velocity, distance and time?
Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away, when the ice was drifting in the same direction, hence:
[tex]v_i + v_s = \frac{360}{12}[/tex]
[tex]v_i + v_s = 30[/tex]
[tex]v_i = 30 - v_s[/tex]
In the return trip, with the ice in opposite direction he took 15 hours, hence:
[tex]v_s - v_i = \frac{360}{15}[/tex]
[tex]v_s - v_i = 24[/tex]
Since [tex]v_i = 30 - v_s[/tex]:
[tex]v_s - 30 + v_s = 24[/tex]
[tex]2v_s = 54[/tex]
[tex]v_s = 27[/tex]
The speed of Fred’s snowmobile was of 27 miles per hour.
