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?
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.

Find the Distance, d, across the lake
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]
[tex]d = \dfrac{15\times 14}{8}[/tex]
[tex]d = 26.25[/tex]
Hence, the Distance, d, across the lake is 26.25 feet.

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
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.
