Answer:
Solid formed will be a CONE
Radius of the cone = 3 units
Step-by-step explanation:
Given points of a triangle are A(0, 0), B(3, 5) and C(0, 5).
Given triangle is a right triangle.
When the given triangle ABC is rotated about a line AC, a 3D image of a solid will be created in the form of a CONE.
This cone will have the radius = BC
Length of side BC = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
= [tex]\sqrt{(3-0)^2+(5-5)^2}[/tex]
= 3
Therefore, radius of the cone = 3 units
A random sample of 48 was taken from a shipment of 10,080 light bulbs from Light Bulbs Express. Out of the 48 light bulbs, 5 were red. How many red bulbs would you expect in the entire shipment?
______________red bulbs (Round answer to the nearest whole number).
A random sample of 62 was taken from another shipment of 15,500 from Light Bulbs R Us. There were 6 red bulbs in the sample. How many red bulbs would you expect in the entire shipment?
_____________red bulbs (Round answer to the nearest whole number)
Which company has the highest ratio of red bulbs in their shipment?
Company ______ (Type either A or B)
Company A = Light Bulbs Express
Company B = Light Bulbs R Us
Answer:
1. Expected(Red) in Shipment A = 1,050
2. Expected(Red) in Shipment B = 1,500
3. Company A has highest ratio of red bulbs
Step-by-step explanation:
Given
Shipment A (Light Bulb Express):
Total Light Bulb = 10,080
Sample Size = 48
Red Bulbs = 5
To calculate the expected number of Red bulbs;
We start by calculating the probability of Red;
P(Red) = Number of Red / Sample Size
P(Red) = 5/48
Expected Number of Red Bulbs is calculated as follows;
Expected(Red) = P(Red) * Total Light Bulb
Expected(Red) = 5/48 * 10,080
Expected(Red) = 50400/48
Expected(Red) = 1,050
Hence, the expected number of red light bulbs in the entire shipment is 1,050
Given
Shipment B (Light Bulb R Us):
Total Light Bulb = 15,500
Sample Size = 62
Red Bulbs = 6
To calculate the expected number of Red bulbs;
We start by calculating the probability of Red;
P(Red) = Number of Red / Sample Size
P(Red) = 6/62
Expected Number of Red Bulbs is calculated as follows;
Expected(Red) = P(Red) * Total Light Bulb
Expected(Red) = 6/62 * 15,500
Expected(Red) = 93000/62
Expected(Red) = 1,500
Hence, the expected number of red light bulbs in the entire shipment is 1,050
The company with highest probability has the highest ratio;
For Company A (Light Bulb Express)
Probability = 5/48
Probability = 0.1042
For Company B (Light Bulb R Us)
Probability = 6/62
Probability = 0.0968
Since 0.1042 is greater than 0.0968, we can conclude that Company A has the highest ratio of red bulbs;

Melinda works at a cafe. Each day that she works, she records x, the total dollar amount of her customers’ bills and then y, her total daily wages. The table shows her data for 2 weeks. A 2-column table with 11 rows. The first column is labeled x with entries 50, 100, 75, 80, 90, 140, 150, 95, 125, 160, 165. The second column is labeled y with entries 36, 43, 38, 40, 42, 50, 60, 43, 46, 50, 55. A graph shows the horizontal axis numbered 40 to 160 and the vertical axis numbered 10 to 60. A line increases from 0 to 160. According to the line of best fit, what is the minimum amount, to the nearest dollar, Melinda will earn for each day of work, even if she serves no customers? $18 $26 $36 $40
Answer:
$26
Step-by-step explanation:
In the picture attached, the table, the plot and the line of best fit are shown. There we can see the next equation:
y = 0.177x + 25.936
where x is the total dollar amount of her customers’ bills and then y is her total daily wages.
This means that even if she serves no customers (x = 0) she will earn $26 ($25.936 rounded to the nearest dollar) for each day of work.
Answer:
$26
Step-by-step explanation:
Looking at the graph when x is 0 y is about a little more that 25 but less than 30. Meaning 26 fits the questions answer.

How do you find out a histograms least frequency interval
Answer:
Histograms are graphs of a distribution of data designed to show centering, dispersion (spread), and shape (relative frequency) of the data. Histograms can provide a visual display of large amounts of data that are difficult to understand in a tabular, or spreadsheet form.
They are used to understand how the output of a process relates to customer expectations (targets and specifications), and help answer the question: "Is the process capable of meeting customer requirements?"
To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping intervals of a variable.

Which set represents the same relation as the table below? x f(x) 0 5 4 2 6 9 9 10 StartSet (0, 5), (4, 2), (6, 9), (9, 10) EndSet StartSet (5, 0), (2, 4), (9, 6), (10, 9) EndSet StartSet 0, 2, 4, 5, 6, 9, 10 EndSet StartSet 2, 5, 9, 10 EndSet
Answer:
1) {(0,5), (4,2), (6,9), (9,10)}
Step-by-step explanation:
Lets right the table in more clearer view.
x f(x)
0 5
4 2
6 9
9 10
The relation in coordinates form is written as (x, y) , x being the first term and y being the second term.
For x = 0, y = 5, so it can be written as (0,5)
Similarly, we can write the next values as:
(4,2)
(6,9)
(9,10)
So the data in the table is:
(0,5), (4,2), (6,9), (9,10)
It can be written is a set form
{(0,5), (4,2), (6,9), (9,10)}
Which is the same as option 1.
Hence, Option 1 is correct.

Jesse is in a lab examining sizes of skin cells. Cell A has a diameter of 5.8 × 10 ^-9 mm. Cell B has a diameter of 4.2 × 10 ^-7 mm.
How much longer is the diamter of Cell B than Cell A?
A. 1.6 x 10 ^-2
B. 1.6 x 10 ^-16
C. 4.14 x 10 ^-7
D. 4.14 x 10 ^-9
Answer:
The diameter of Cell B is [tex]4.14 \times 10^{-7} mm[/tex] longer than Cell A
Step-by-step explanation:
Diameter of Cell A = [tex]5.8 \times 10^{-9} mm[/tex]
Diameter of Cell B = [tex]4.2 \times 10^{-7} mm[/tex]
Now we are supposed to find How much longer is the diameter of Cell B than Cell A?
So,Diameter of Cell A =[tex]5.8 \times 10^{-9} = 5.8 \times 10^{-7} \times 10^{-2}=5.8 \times 10^{-7} \times \frac{1}{10^2} = 0.058 \times 10^{-7}[/tex]
Diameter of Cell B = [tex]4.2 \times 10^{-7} mm[/tex]
So, Difference in diameters = [tex]4.2 \times 10^{-7} - (0.058 \times 10^{-7})=4.14 \times 10^{-7}[/tex]
So, Option C is true
Hence the diameter of Cell B is [tex]4.14 \times 10^{-7} mm[/tex] longer than Cell A

Four friends hosted a Graduation party: Genesis spent $21 for drinks, Mya spent $25 for food, Alina spent $16 for invitations, and Mylana spent $18 for decorations. The friends want to share the party expenses equally, and Alina will pay the entire amount she owes to one person. Who owes money to whom?
Answer:
Alina owes $4 to Mya and Mylana owes $1 to Mya and $1 to Genesis.
Step-by-step explanation:
As they want to share the party expenses equally, first you have to add all the expenses and divide them by 4 people to know the amount that each person has to pay:
$21+$25+$16+$18= $80/4= $20
As everyone has to pay $20 for the party expenses, we can see that Genesis spent $1 more and Mya $5 more, so they have to get the money back from the other 2 people.
Alina owes: $20-$16= $4. She owes $4 to Mya as she will pay the entire amount she owes to one person and Mya has to get $5 back.
Mylana owes: $20-$18= $2. She would have to pay $1 to Mya to complete the $5 she had to get back and $1 to Genesis.

Estimate 3 3/8 X 10 13/15
Answer:
36.70
Hope this helps!
Answer:
The estimation of this equation is the number 33
Step-by-step explanation:
First Estimate is defined as to roughly calculate or judge the value of a number or a quantity. In this case we are roughly calculating a number or otherwise known as a fraction. So 3 3/8 would be Rounded to the whole number 3 , due to the fact that the 3/8 is less then the 4/8 , and the 10 13/15 would be estimated to 11 , due to the fact that is more than the 7.5/ 15 . So, 3 times 11 would be the estimate of 33.

Ann increased the quantities of all the ingredients in a recipe by 60% She used 80 grams (g) of cheese How much cheese did the recipe require?
Answer:g = 50 g
Step-by-step explanation:
She used 60% more than required ⇒ she used (1+0.60)=1.60 times what was required.
x = grams required by the recipe
80 g = 1.60x
x = (80/1.60) g = 50 g
Factor completely 3x2 − 11x + 8
A. (x + 4)(3x - 2)
B. (x − 2)(3x − 4)
C. (x + 1)(3x − 8)
D. (x − 1)(3x − 8)
Answer:
The Answer is D. (x - 1) (3x - 8)
Step-by-step explanation:
So, we start with [tex]3x^2 - 11x +8[/tex].
First step is to break the expression into groups, by doing this, you get:
[tex]\left(3x^2-3x\right)+\left(-8x+8\right)[/tex]
Next, factor out the 3x from [tex]\left(3x^2-3x\right)[/tex]. By doing this, you should get:
3x(x - 1)
Then, factor out the 8x from [tex]\left(-8x+8\right)[/tex]. By doing this, you will get:
-8(x - 1)
Last, factor out the common term, x - 1, When you do this, you get:
(x - 1) (3x - 8)
Hope this helps!

The smallest number by which 192 should be multiplied to make it a perfect cube is
Answer:
[tex]9[/tex]
Step-by-step explanation:
The prime factorization of [tex]192[/tex] is [tex]2^6 \cdot 3[/tex], and since [tex]2^6[/tex] is already a perfect cube of [tex]4[/tex], we just have to deal with the [tex]3[/tex]. To make it a perfect cube, we have to multiply [tex]3[/tex] three times, and so we have to make it [tex]3 \cdot 3 \cdot 3[/tex], and we already have one three so we just add the other two threes, which equal [tex]3^2=9[/tex].
