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?
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.

The area of shaded rectangle is 8/3 square units.
To find the area of shaded rectangle.
What is rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees.
Given that:
length=4 units
width= 1-unit
The rectangle is subdivided into 3 parts parallely.so 1 units is unshaded and rest are shaded.
Area of rectangle =length*width
Area of bigger rectangle =length*width
=4*1 square units
=4 square units
width is subdivided into 3 parts .
so, 1/3,1/3,1/3 are the width.
Area of un shaded rectangle=length*width
=4*1/3 square units
=4/3 square units
so, Area of bigger rectangle=Area of un-shaded rectangle+ Area of shaded rectangle
4 =4/3+Area of shaded rectangle
Area of shaded rectangle=4-4/3
Area of shaded rectangle=12-4/3
Area of shaded rectangle=8/3 square units
Therefore, the area of shaded rectangle=8/3 square units.

An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__
Answer:
Profit = $(700 - 42x - 56y)
Step-by-step explanation:
For large candles, the selling price is $10 and its making cost is $x.
So, by selling a large candle the profit is $(10 - x)
Again for small candles, the selling price is $5 and its making cost is $y.
So, by selling a small candle the profit is $(5 - y)
Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)
⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}
⇒ P = $(700 - 42x - 56y) (Answer)

Which expression would be easier to simplify if you used associative property to change the grouping.
A. 4+(1.2+(-0.2))
B. 85+(120+80)
C. [-40+(60)]+52
D (2+3/7)+4/7
(I'll give brainliest for the correct and most accurate answer.)
Answer:
D. (2 + 3/7) + 4/7
Step-by-step explanation:
In B and C, the numbers involved in expressions are integers.
Hence, they can be easily added or subtracted.
In D, the numbers involved in expression are fractions which are not grouped together.
They can be added but by using associative property, it becomes much more easier.
That is, grouping fractions.

1. The relationship between a distance in yards (y) and the same distance in miles (m) is
described by the equation y = 1760m.
a. Find measurements in yards and miles for distances by filling in the table.
distance measured in miles
distance measured in yards

3,520
17,600
b. Is there a proportional relationship between a measurement in yards and a
measurement in miles for the same distance? Explain why or why not.
Therefore, the ratio of yards to miles is always constant, making it a proportional relationship.
What is equation?An equation is a mathematical statement that shows the equality between two expressions. It typically includes one or more variables, which are unknowns that can take on different values. An equation can be solved by finding the value or values of the variable(s) that make both sides of the equation equal.
Here,
a. Using the equation y = 1760m, we can fill in the table as follows:
distance measured in miles distance measured in yards
1 1,760
5 8,800
3.520 6,195.2
17,600 30,800,000
b. Yes, there is a proportional relationship between a measurement in yards and a measurement in miles for the same distance. The equation y = 1760m shows that the number of yards is always 1760 times greater than the number of miles. This means that if you double the number of miles, the number of yards will also double, and if you triple the number of miles, the number of yards will triple, and so on.

What is the danger zone for bacteria? A. Below 40 B. Between 40 and 140 C. Above 140 D. The only safe temperatures are between 40
Answer:
B
Explanation:
Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours.
Answer:
B. Between 40 and 140 Fahrenheit
Step-by-step explanation:
This is called the "Danger Zone" because between these temperatures bacteria grow the fastest. Doubling time can be as little as 20 minutes.

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
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.
