A grocery store has three locations: Central, North, and South. The grocery store counted the number of cantaloupes sold at each of the three locations each day for a month. The table shows the mean and the mean absolute deviation of the number of cantaloupes sold each day. Which statements are correct? Select each correct answer.
The number of cantaloupes sold at North and South varied about the same amount.
The number of cantaloupes sold at Central varied less than did the number sold at North.
The number of cantaloupes sold at Central and South varied about the same amount.
The number of cantaloupes sold at Central varied more than did the number sold at South.
Store location Mean number of sales MAD Central 45 4.1 North 47 5.7 South 29 5.9
Answers
The correct option is The number of cantaloupes sold at Central varied less than did the number sold at North.
What is the mean absolute deviation?The means absolute deviation is the average distance of each of the data points about the mean.
The below-given table shows the data of the three different stores.
Store location Mean number of sales MAD
Central 45 4.1
North 47 5.7
South 29 5.9
As we know that the mean absolute deviation shows as the average of the difference in the mean data that can occur. Therefore, it shows us the amount by which the data can deviate from its mean.
Now, if we look at the option, the only option that is correct about the given data is "The number of cantaloupes sold at Central varied less than did the number sold at North".
The statement holds true because the Mean absolute deviation for the store in the center is least, therefore, it varies the least from all the given options.
Hence, the correct option is The number of cantaloupes sold at Central varied less than did the number sold at North.

A diner has a breakfast special. A customer can chose scrambled, fried, or poached eggs. The breakfast comes with a side of bacon, sausage, or fruit salad. The customer can choose coffee, tea, or milk. How many different combinations of eggs, side, and drink does a customer have to choose from?
Solution:
Number of ways the customer can choose eggs=3
Number of ways the customer can choose side=3
Number of ways the customer can choose drinks=3
So, total number of combinations for choosing eggs and side and drinks
=3(for eggs) and 3(for sides) and 3(for drinks)
=3 * 3 *3
=27
A customer has 27 combinations of eggs, side, and drink available.
A college entry exam has 38 questions worth 200 points. The test consists of multiple-choice questions, x, worth 4 points each and essay questions, y, worth 10 points each. Which system of equations can be solved to find the number of multiple-choice questions on the test?
Answers
There are no options listed in the question to choose from, but the equations should look like the following:
x= # multiple choice questions
y= # essay questions
QUANTITY EQUATION:
x + y= 38
VALUE EQUATION:
4x + 10y= 200
If we solved these two equations by elimination or substitution, we would find the number of multiple choice (x) and the number of essay (y) questions on the test.
ANSWER: x + y= 38; 4x + 10y= 200
Hope this helps! :)
Answer:
Let's use the variables x and y to represent the number of multiple-choice and essay questions on the test, respectively.
The total number of questions is 38, so we can write:
x + y = 38
The total number of points is 200, so we can write:
4x + 10y = 200
This gives us a system of equations:
x + y = 38
4x + 10y = 200
We can solve this system of equations to find the number of multiple-choice questions on the test.

What is the volume of a pyramid?The volume of a pyramid is [tex]\frac{1}{3} Ah[/tex] where A is the area of the base of the pyramid and h is the height.
Area of the base = area of a rectangle with dimensions 12cm*10cm
Area of the base =12*10 =120 cm²
Height of the pyramid =16cm
So, the volume of the pyramid = [tex]\frac{1}{3}*120*16[/tex] cm³

Susan gets paid x dollars per hour. After 40 hours she gets paid time and a half (1.5 times her normal hourly pay). Last month she worked 52 hours each week and earned $696 each week. How much does Susan get paid per hour?
Answers
Let x be the amount she gets paid per hour. Working 40 hours would then be represented by 40x.
Anything over 40 hours earns her 1.5 her normal rate, or 1.5x. Since she works 52 hours, this means 52-40=12 hours of overtime at 1.5x:
12(1.5x) = 18x
Together, she earned 696:
40x+18x = 696
Combining like terms,
58x = 696
Divide both sides by 58:
58x/58 = 696/58

You have to use similar figures to work this out.

You then times 1.875 by 6 = 11.25
The Distance, d, across the lake is 26.25 feet.
Similar TrianglesWhen two triangles have all the corresponding angles equal to each other, then their sides are in a ratio.
Given to us,AB = 8 feet,
BC = 15 feet,
BP = 6 feet,
PQ = d,
AP = AB + BP = 8 + 6 = 14 feet
In the figure, [tex]\triangle ABC \sim \triangle APQ[/tex]
[tex]\dfrac{BC}{AB}=\dfrac{PQ}{AP}[/tex]
[tex]\dfrac{15}{8}=\dfrac{d}{14}[/tex]

which of the following functions is continuous between x=-3 and x=0? choices on attachment
Answers
A: f(x) = (-x + 1)/(x + 2)
Now we don't actually need to know what the graph of this function looks like to see which values it is continuous for, instead we should look at which values of x will make this function undefined - in this case that would be x = -2. The reasoning behind this is that a number divided by 0 would be undefined, so when we search for which value of x would make the denominator of the equation 0, we get:
x + 2 = 0
x = -2
Since x = -2 is within the interval [-3, 0] we cannot say the function is continuous over this interval
B: f(x) = -2/(x + 1)
Using the same method as above we get:
x + 1 = 0
x = -1
x = -1 is again within the interval [-3, 0] and so the function is not continuous within this interval
C: f(x) = 3x/(x - 2)
x - 2 = 0
x = 2
x = 2 is outside the interval of [-3, 0] and so the function is continuous within this interval and C is the correct answer.
Just for the sake of it however we can look at D as well:
D: f(x) = 1/(2x + 1)
2x + 1 = 0
x = -1/2
-1/2 is within [-3, 0] and so D is not continuous over this interval
