Mr Davis has displayed data using box and whisker plots representing the scores on the first exam in his two calculus classes. Using these plots, what can Mr Davis correctly deduce about how the two classes compare?
Answers
Answer: The first and third choices are deductions that Mr. Davis can make from the data displayed.
Step-by-step explanation: The last choice is partly true. The highjest individual score was a student in third period, but most schools consider failing to be somewhere below 60 to 67%. There are several of scores below those numbers. The dots at the left end are "outliers."
The second choice may be true, but the data is about the scores on the test, not the number of students in the classes.

A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.
Answers
greater because 1.6 is larger than 1
Answer:
higher than
Step-by-step explanation:
The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:
110 km hour÷1.6 km mile=110÷1.6 miles hour.
We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit is higher than 65 mph

The Farmers Market sells apples by the bushel, and each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples? It’s says show work
Answers
Answer: 4 apples in 1 lb
Step-by-step explanation: There are twice as many small apples as large apples, so multiply 2 × 84 = 168
to find apples per pound, divide the total number of apples, 168, by the weight of the bushel: 42 lbs.
168 /42 = 4 apples/lb
The required number of small apples in one pound is 4.
Given that,
Each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples, is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Large apples in 1 pound = 84 / 42 = 2
Now, according to the question,
Number of small apples = 2 (number of large apples)
Number of small apples = 2 (2)
Number of small apples = 4
Thus, the required number of small apples in one pound is 4.

Isabelle takes the bus to work. The bus ride to work costs her $2.50 each time. She could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. How many times would she have to take the bus for the cost to be the same?
Answers
y = total cost
x = amount of times she takes the bus
Let's create two equations to model the data in the problem above.
y = $2.50x
y = $1x + $15
Now, let's set them equal to each other and solve for x.
$2.50x = $1x + $15
Subtract $1x from both sides.
$1.50x = $15
Divide both sides by $1.50
x = 10
She would have to ride the bus 10 times for the cost to be equal.
Answer:
10 Trips
Step-by-step explanation:
Create 2 algebraic Equations, X is the number of trips and y is the total cost. y=2.5x, and y=x+15. Set them equal to eachother and solve for X. 2.5X=X+15. Subtract X from both sides to get 1.5X=15. Divide by 1.5 to get 10. X=10, 10 Trips!

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)

The common difference, d, is 3, because the number of squares goes up by 3 each time.
d = 3
Number of squares in nth figure is:
a(n) = 4 + d(n - 1)
4 is the initial number of squares, d is how many it goes up each time, and we take n-1 because you need to account for the initial number of squares.
a(n) = 4 + d(n - 1)
For n = 200
a(n) = 4 + d(n - 1)
a(200) = 4 + 3(200-1)
a(200) = 4 + 3(199)
a(200) = 4 + 597
a(200) = 601

Answer: The slope is 6.
Step-by-step explanation:
One way to see the slope is to look at the graph and find places where the graphed line crosses the corners formed by the grid lines. Then count the number from top to bottom and divide that number by the number of blocks left to right (IF the scale is the same for both the x-axis and y-axis!) Then divide up-down number by left-right number. If it is the same, the slope is 1.
Here the line crosses the y axis at -1 exactly: (0, -1) The next place where it crosses the corner exactly is at (1, 5). Counting blocks: 6 from top to bottom, only 1 left to right 6/1
Or do it with the numbers: Find the difference in y-values, them divide by the difference in x-values, Using Coordinates (0,-1) and (1,5) the difference in y-values is 5-(-1) = 5+1 = 6 The difference in x-values is 1 - 0 = 1 6÷1 = 6
