Answer:
segment BC is located at B (4, 0) and C (4, 12) and is twice the size of segment B prime C prime.
is the answer all you have to do to find the dilation is multiply it by the number factor if its getting bigger and divide if its getting smaller or add or subtract if decimal
The correct statement that describes the pre-image is - 'segment BC is located at B (1, 0) and C (1, 3) and is one-half the size of segment B prime C prime.'
What is dilation?"changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors."
For given question,
Segment B'C' has endpoints B'(2, 0) and C'(2, 6).
Segment BC was dilated at a scale factor of 2 from the origin.
To find the dilation,
Multiply original dimension by the scaling factor if its getting bigger and divide if its getting smaller.
We know that, if the scale factor is more than 1, then the image stretches.
This means, the image B'C' is larger than the pre-image BC
So, to find the pre-image that is, segment BC, we need to divide the dimensions of the image.
\(\Rightarrow B=\frac{1}{2}B'~~~and~~~C=\frac{1}{2}C'\\\\\Rightarrow B=\frac{1}{2}(2,0)~~~and~~~C=\frac{1}{2}(2,6)\\\\\Rightarrow B=(1,0)~~~and~~~C=(1,3)\)
Therefore, the correct statement that describes the pre-image is - 'segment BC is located at B (1, 0) and C (1, 3) and is one-half the size of segment B prime C prime.'

a painter mixes 4 quarts of blue paint with every 3 quarts of red paint to make purple paint. How many quarts of red paint will he need to make 17.5 quarts of the same shade of purple
To make the same shade of purple paint, the painter needs to mix 4 quarts of blue paint with every 3 quarts of red paint. If the painter wants to make 17.5 quarts of purple paint, he will need approximately 13.125 quarts of red paint.
According to the given information, the ratio of blue paint to red paint required to make purple paint is 4:3. This means that for every 4 quarts of blue paint, the painter needs 3 quarts of red paint.
To determine how many quarts of red paint the painter needs to make 17.5 quarts of purple paint, we can set up a proportion. Let's call the unknown quantity of red paint "x" quarts:
4 quarts of blue paint / 3 quarts of red paint = 17.5 quarts of purple paint / x quarts of red paint
Cross-multiplying the equation, we get:
4x = 3 * 17.5
Simplifying further:
4x = 52.5
Dividing both sides by 4:
x = 52.5 / 4 = 13.125
Therefore, to make 17.5 quarts of the same shade of purple paint, the painter will need approximately 13.125 quarts of red paint.

Last week a painter painted 6 houses in 2 days. this week she painted 5 houses in 4 days. in which week was the painter more productive?
Answer:
The painter was more productive in week a.
Step-by-step explanation:
Find the unit rate. How many houses could be painted in 1 day?
6/2 means that she could paint 3 houses per day
5/4 means that she could paint 1.25 houses per day.
The painter was more productive in the last week.
Explanation:In this problem, we need to find in which week did the painter paint the most.
To find the solution to this problem, first, we need to divide 6 by 2 (last week)
which equals 3.
Next, divide 5 by 4 (this week)
which equals 1.25
Now, compare the two quotients and identify the larger number (3 and 1.25).
Basically, we can see that the number 3 is larger.
This means that the painter could paint 3 houses per day in the last week, and 1.25 houses per day in this week.
Therefore, we can say that the painter was more productive in the last week.

Priya is buying raisins and almonds to
make trail mix. Almonds cost $5.20 per
pound and raisins cost $2.75 per pound.
Priya spent $11.70 buying almonds and
raisins. The relationship between
pounds of almonds a, pounds of raisins
r, and the total cost is represented by
the equation 5.20a + 2.75p = 11.70
How many pounds of raisins did Priya
buy if she bought the following amounts
of almonds:
1. 2 pounds of almonds
2. 1.06 pounds of almonds
3. 0.64 pounds of almonds
4. a pounds of almonds
Using the equation, the pounds of raisins Priya bought, spending a total of $11.70 if she bought the following amounts of almonds are:
1. 2 pounds of almonds and pounds of raisins will be 0.473 pounds.
2. 1.06 pounds of almonds and pounds of raisins will be 2.47 pounds.
3. 0.64 pounds of almonds and pounds of raisins will be 3.04 pounds.
4. A pound of almonds and pounds of raisins will be 2.36 pounds.
What is an equation?An equation is a mathematical statement that lays the claim that two mathematical expressions are equal or equivalent.
Cost per unit (Almonds) = $5.20
Cost per unit (Raisins) = $2.75
Total cost spent for Almonds and Raisins = $11.70
Equation relationship:
Let pounds of almonds = a
Let pounds of raisins = r
Total cost equation: 5.20a + 2.75r = 11.70
Pounds of Raisin to Almonds:1. 2 pounds of almonds and pounds of raisins will be:
5.20(2) + 2.75r = 11.70
10.40 + 2,75r = 11.70
2.75r = 11.70 - 10.40
2.75r = 1.30
r = 0.473 (1.30/2.75)
r = 0.473 pounds
2. 1.06 pounds of almonds and pounds of raisins will be:
5.20(1.06) + 2.75r = 11.70
4.90 + 2.75r = 11.70
2.75r = 6.80
r = 2.47 pounds
3. 0.64 pounds of almonds and pounds of raisins will be:
5.20(0.64) + 2.75r = 11.70
3.33 + 2.75r = 11.70
2.75r = 11.70 - 3.33
2.75r = 8.372
r = 3.04 pounds
4. A pound of almonds and pounds of raisins will be:
5.20(1) + 2.75r = 11.70
5.20 + 2.75r = 11.70
2.75r = 11.70 - 5.20
2.75r = 6.5
r = 2.36 pounds

Tekan-Tekan Sdn. Bhd. has order for 200 Model AS-120 calculator for delivery on day 200. The calculator consists of three parts. Components 2 and 3 form subassembly 1 . Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

3.27 Underage drinking, Part II. We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008. We now consider a random sample of fifty 18-20 year olds. (a) How many people would you expect to have consumed alcoholic beverages? And with what standard deviation? (b) Would you be surprised if there were 45 or more people who have consumed alcoholic beverages? (c) What is
Answer:
a) Number of people expected to have consumed alcoholic beverages in the sample = 35.
Standard deviation = 3.24
b) 45 or more people consuming alcoholic beverages in the sample is about 3 standard deviations from the mean (35), hence, it would be surprising if this happened since most of the possible values in a distribution stay well within a few standard deviations of the mean.
c) The probability that 45 or more people in this sample have consumed alcoholic beverages = 0.0017
The mathematical and statistical chances of 45 or more people who have consumed alcoholic beverages in the sample is very low (0.0017), hence, it will be very surprising if this happened.
Step-by-step explanation:
Concluding part of the question
What is the probability that 45 or more people in this sample have consumed alcoholic beverages? How does this probability relate to your answer to part (b)?
a) The expected number of people that take alcoholic beverages in a sample of people is the mean of a binomial distribution and it is given as
Mean = np
where n = sample size = 50
p = population proportion of youths that take alcoholic beverages = 70% = 0.70
Number of people expected to have consumed alcoholic beverages in the sample = 0.70 × 50 = 35
The standard deviation is given as
σ = √[np(1-p)] = √(50×0.70×0.30) = 3.24
b and c) To investigate whether one should be surprised if 45 or more people out of the sample take alcoholic beverages, we first find the probability of this happening.
If the probability is very small or minute.
Using the normal approximation to the binomial distribution,
μ = 35
σ = 3.24
If X denotes the number of people that will take alcoholic beverages in the sample.
And we need P(X ≥ 45)
we first introduce the continuity correction factor.
P(X ≥ 45) = P(x ≥ 44.5)
We normalize or standardize the number 44.5
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (44.5 - 35)/3.24 = 2.93
To determine the required probability
We'll use data from the normal distribution table for these probabilities
P(X ≥ 45) = P(x ≥ 44.5) = P(z ≥ 2.93)
= 1 - P(z < 2.93)
= 1 - 0.99831
= 0.00169 = 0.0017 to 4 d.p.

A segment is m units long. Find the distance between the midpoints of the first and last parts if the segment is divided into 5 equal parts.
The midpoints of the first and last parts are 4/5m units apart
How to determine the distance between the midpoints?The length of the line segment is given as
Length = m units
From the question, the number of partitions is given as
Partition = 5
So, the length of each partition is
Each partition = Length/Partition
This gives
Each partition = m/5
The midpoint of a partition is
Partition midpoint = m/5 x 1/2
Evaluate
Partition midpoint = m/10
The distance between the midpoints of the first and last segments is then calculated as
Distance = Length - 2 x Partition midpoint
So, we have
Distance = m - 2 x m/10
Evaluate
Distance = m - m/5
This gives
Distance = 4/5m
Hence, the distance is 4/5m units
