Item 4 A manager drew this box-and-whisker plot to represent the weights, in pounds, of the 19 crates he is shipping. Every crate weighs a different amount. Box-and-whisker plot ranging from 80 to 180 with ticks at increments of 2.5. Plot defined by points at 84, 99.5, 113, 143, 170. How many crates weigh less than 99.5 pounds? Enter your answer in the box.
Answers
Answer:
4
Step-by-step explanation:
i took the test :)
The number of crates that weigh less than 99.5 pounds is 4 crates.
How does a boxplot shows the data points?A box plot has 5 data description.
The leftmost whisker shows the minimum value in the data.The rightmost whisker shows the maximum value in the data.The leftmost line in the box shows the first quartile.The middle line shows the median, also called second quartile.The last line of the box shows the third quartile.What are quartiles?When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.Similarly, second quartile (also called median) is approximately in mid of the data.Third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.Left to right is said in assumption that data was arranged increasingly from left to right
For this case, we're specified that:
Plot defined by points at 84, 99.5, 113, 143, 170
So, we have:
Minimum at 84, first quartile = 99.5, second quartile = median = 113, third quartile = 143, maximum value = 170
We want to know the amount of crates that weigh less than 99.5 pounds.
Assuming that data of the weights of the crates was arranged increasingly from left to right, as the first quartile is 99.5 and first quartile has 25% of data in its left, we get that 25% of the crates weigh less than 99.5 pounds.
Now, since there are 19 crates, so its 25% is:
[tex]\dfrac{19}{100} \times 25 = 4.75[/tex]
Total 4 crates completely lie below fist quartile(99.5), so total 4 crates out of 19 crates considered weigh less than 99.5.

2 and 9
Step-by-step explanation:
-4 - (-6) = 2
6 - (-3) = 9
Hope this helps :)
Answer: 2, 9
Step-by-step explanation:
Equation 1
-4 - (-6)
-4+6= 2
This is because whenever you have a number minus a negative number like x - (-y), you cross out the 2 minuses and make them a +. Let's do the same for the 2nd equation:
6-(-3)
As I mentioned, the 2 minuses become a plus, so you just get rid of them. Now, we have 6+3
6+3= 9
What is the area of this figure?
Select from the drop-down menu to correctly complete the statement.
The area of the figure is 'blank' cm².
Answers
Answer:
The area is 146cm squared
Step-by-step explanation:
Starting with the top portion, The formula for the area of a trapezoid is a = (base 1 + base 2) / 2 * h | (14 + 4) /2 *10 = 90.
Now for the bottom part, We know that the height of the top of the figure is 10 and that the overall figure height is 18. To find the height of the triangle at the bottom we would do 18 - 10 = 8.
The formula for finding the area of a triangle is b x h / 2 = a. 14 * 8 / 2 = 56.
Finally, we add our results. 90+56=146.

Answer:
y = 3n - 2
Step-by-step explanation:
so to find the slope or rate of change we use the equation
y 2 - y1 / x2 - x1
soo lets use the points
(1, 1) and (2, 4)
4 - 1/ 2 - 1
3/1
3
y = 3n + b
now we substitute a point we did not use yet
(3, 7)
7 = 3(3) + b
7 = 9 + b
b = -2
y = 3n - 2
now check
(4,10)
10 = 3(4) - 2 ?
10 = 12 - 2 ?
10 = 10
Answer:
y = 3n - 2
Step-by-step explanation:
y = mx + b or y = nx + b
Where m or n represents the slope
[tex]m\ or\ n=\frac{y_2-y_1}{x_2-x_1} \\\\m\ or\ n=\frac{4-1}{2-1} \\\\m\ or\ n=\frac{3}{1} \\\\m\ or\ n=3[/tex]
y = 3n + b
(n, y) ==> (2, 4)
y = 3n + b
4 = 3(2) + b
4 = 6 + b
-6 -6
-2 = b
y = 3n - 2
Check your answer using (2, 4):
y = 3n - 2
4 = 3(2) - 2
4 = 6 -2
4 =4
This statement is correct

where do y = -x + 8 and y = x - 2 intersect
Answers
Answer:
(5,3)
Step-by-step explanation:
To find where two lines intersect you let them equal to each other.
-x + 8 = x -2
Add 2 on both side
-x + 10 = x
Add x on both sides
10 = 2x
Divide 2 on both sides
5 = x
Now plug x into both equations
y = -5 + 8 = 3
y = 5 - 2 = 3
so y = 3
The point they intersect is (5,3)
1). y=x;(2,3) Tell whether the ordered pair is a solution of the equation. 2) Y=3x -2; (1,1)
Answers
Answer:
1) no, (2,3) is not a solution of y=x.
2) yes, (1,1) is a solution of y=3x-2
Step-by-step explanation:
When you have a point, the first number is x and the second number is y, (x,y).
If you substitute the numbers in for x and y, you will get a true statement if the point is a solution.
Look at y = x, put in 2 for x and 3 for y.
You get 3 = 2, that's false. So (2,3) is NOT a solution of y = x.
Then consider
y = 3x - 2; fill in 1 for x and 1 for y
You get
1 = 3(1) - 2
1 = 1 , a true statement. So (1,1) IS a solution.
Answer:
(2, 3) is not an ordered pair for y = 3x - 2.
Step-by-step explanation:
(2,3)
y = 3x - 2
3 = 3(2) - 2
3 = 6 - 2
3 = 4
This means that (2, 3) is not an ordered pair for y = 3x - 2.

4. if a cleaning service charges $1000 for 20 offices then divide 1000 by 20 and 20 by 20 to have an answer of $50 for every one office.
5. to find the answer to this problem you need to divide 320 by 4 to find out organes per bag so 80 oranges per bag.
6. if the baker ca bake 12 cakes every 45 minutes then he can bake 4 cakes every 15 minutes because divide both 12 and 45 by three so in conclusion the baker can bake 16 cakes every hour.

x = customers
1 = the elevator operator
< 17 = the amount of people that can be in the elevator at a time
Together, we get our inequality:
x + 1 < 17
The customers + the operator in the elevator should not be greater than 17.
