Answer:
(a) 25
(b) 9.27
Step-by-step explanation:
Step 1
We have to rearrange the given days set from least to highest
35, 40, 45, 55, 60
(a) the range
Range = The highest number - The least number
= 60 - 35
= 25
(b) the standard deviation of the data set
35, 40, 45, 55, 60.
We find the Mean
Mean = Sum of values/Number of values
= 35+40+45+55+60/5
= 235/5
= 47
We can find the standard deviation now.
The formula =
√(x - Mean)²/n
= √(35 - 47)²+ (40 + 47)² + (45 - 47)² + (55 - 47)² + (60 - 47)²/5
= √144 + 49 + 4 + 64 +169/5
= √430/5
= √86
= 9.273618495
Approximately = 9.27

Answer:
The statement that best describes how the author of "The Train to Somewhere" alters historical details to tell her story is option B;
B. The author describes the experiences and feelings of an imaginary orphan who was sent west on an orphan train
Step-by-step explanation:
The author included the experiences of one of the children who according to the historical details in the historical account of the Orphan Train Riders were aided by the minister, Charles Loring Brace, to be taken from the New York City streets on the East to other states and Canada to the West
The child, a 5 year old girl, who had lost both parents had been living on the street with her brother for some months

Which expressions are equivalent to the one below? Check all that apply 5^x
Answer:
5 * 5^(x - 1) ; (15/3)^x ; 15^x / 3^x
Step-by-step explanation:
From the options, equivalent expressions include :
(15/3)^x
This is the same as ;
(15/3)^x
15 ÷ 3 = 5 ; then to the power of x = 5^x
15^x / 3^x ; since they are both raised to the same power, we can divide directly to obtain :
5^x
5 * 5^(x - 1)
5 = 5^1
5^1 * 5^(x-1)
5^(1 + x - 1) = 5^x

Notice that the weird figure looks like a rectangle that is missing a piece.
In this case, find the area of the rectangle... then subtract the area of the missing piece from that area of the rectangle.
-----------------------------------------------------------------------
Area of rectangle: 4 x 5 = 20 sq. inches
-----------------------------------------------------------------------
How to find the area of the missing piece:
Notice that the other side is 2 inches while the left side is 4 inches, which means that if I subtract 2 from 4... then I will know the width of the missing piece. [4 - 2 = 2 inches is the width of the missing piece.]Notice that the top side is 4 inches while the bottom side is 5 inches, which means that if I subtract 4 from 5... then I will know the length of the missing piece. [5 - 4 = 1 inch is the length of the missing piece].So, the area of the missing piece: A = lw = (1)(2) = 2 sq. inches
-----------------------------------------------------------------------
Now, subtract the area of the missing piece from the area of the rectangle:
20 - 2 = 18 sq. inches
-----------------------------------------------------------------------
ANSWER: 18 sq. inchesfactor the trinomial 16x2 + 14x + 3
Answer:
Step-by-step explanation:
16x²+14x+3
=16x²+8x+6x+3
=8x(2x+1)+3(2x+1)
=(2x+1)(8x+3)
The number of bagels sold daily for two bakeries is shown in the table.
Bakery A Bakery B
53 34
52 40
50 36
48 38
53 41
47 44
55 40
51 39
Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Why? Select the correct answer below. (5 points)
Mean for both bakeries because the data is symmetric
Mean for Bakery B because the data is symmetric; Median for Bakery A because the data is not symmetric
Mean for Bakery A because the data is symmetric; Median for Bakery B because the data is not symmetric
Median for both bakeries because the data is not symmetric
Answer:
“Mean for both bakeries because the data is symmetric.”
Step-by-step explanation:
This is correct because the numbers shown in this problem is all in the same range. Meaning that on bakery A and B there are no stray numbers, also known as outliers. No outliers means that the data is symmetric. If you search up, you can see that when the data is symmetric, you use “mean.”
also I got it right on my test
Answer:
Mean for both bakeries because the data is symmetric.

Rico and Darla each measured a side and height on the triangle below to find its area.
Rico’s side measured 7.5 m and Darla’s side measured 9 m.
Choose True or False for each statement.
A triangle with two base and side length measurements. One side length is nine meters, and the height from that side is five meters. The other side length is seven and five-tenths meters and the height from that side is six meters.
Darla can use either the height of 6 meters or the height of 5 meters to find the area of the triangle.
Choose...
If Darla uses the height of 6 meters and Rico uses the height of 5 meters, they will find the same area of the triangle.
Choose...
If Rico uses the height of 6 meters and Darla uses the height of 5 meters, they will find the same area of the triangle.
Choose...
The area of the triangle is 22.5 square meters.

Wesley walked 11 miles in 4 hours. If he walked the same distance every hour, how far did he walk in one hour? Using only feet
Answer:
14,520
Step-by-step explanation:
The computation is shown below:
Given that
Wesley walked 11 miles in 4 hours
Now we can say that
1 miles = 5280
So, 11 miles would be
= 5280 × 11
= 58,080
And, the number of hours is 4
So, for one hour he would be far of
= 58,080 ÷ 4
= 14,520

Question 98 Unleaded gas is $2.80 per gallon. Which equation best represents y, the total cost at x pounds of plum?
Answer:
y = $2.80x
Step-by-step explanation:
Based in the information given :
Cost per gallon = $2.80
Number of gallons = x
The total cost, y which is the total cost of x gallons of gas will be :
Cost per gallon * number of gallons
$2.80 * x
Hence,
y = $2.80x

A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situation. Use $x$ to represent the number of roast beef sandwiches. Then determine how many sandwiches the customer buys.
Amount Used for Payment $80
Change Received $19.25
An equation that represents this situation is
.
The customer buys
sandwiches.
Answer:
[tex]\frac{80-19.25}{6.75} = x[/tex]
Step-by-step explanation:
Subtract $19.25 from the Amount Used for Payment ($80) to get the amount spent, then divide the amount of each sandwich to get the amount of sandwiches bought.
