The transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).
What is the dilation of the figure?Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.
When a figure is dilated, the size of the original figure is changed.
A figure is graphed in the coordinate plane. Let's check all the option for the transformation of original figure.
A. Reflect the figure over the line y = x and then translate it 2 units up- Reflection and translation of a figure does not changes its shape and size.B. Translate the figure 3 units to the left and then dilate by a scale factor of 4- With the scale factor of dilation, the size of the figure will be changed for this case.C. Rotate 90 degrees counterclockwise and then dilate by a scale factor of 1- In this case, there the figure is dilated with a scale factor of 1. This will change the size of the original figure.D. To state the figure 180 degrees counterclockwise about the origin and then reflect it over the y-axis- In this case the shape and size does not change.Hence, the transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).

A camp program charges a registration fee and a daily amount.
The total bill for 12 days is $338. The total bill for 19 days is
$506. Slope can be represented by cost per day. Use x as the
number of days and y as the total cost to represent this
situation.
a. Find the slope for this situation. What does it represent?
b. Write a linear equation that models this situation.
Using the information given, it is found that:
a) The slope is of 24, which means that for each day, the total bill increases by $24.b) The linear equation is: [tex]y = 24x + 50[/tex]Linear functions:A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.Item a:
The total bill for 12 days is $338.The total bill for 19 days is $506.The slope is given by the change in y(total bill) divided by the change in x(number of days), hence:
[tex]m = \frac{506 - 338}{19 - 12} = 24[/tex]
The slope is of 24, which means that for each day, the total bill increases by $24.
Item b:
The total bill for 12 days is $338, hence, when [tex]x = 12, y = 338[/tex], and this is used to find b.[tex]y = 24x + b[/tex]
[tex]338 = 24(12) + b[/tex]
[tex]b = 50[/tex]
Hence, the linear equation is: [tex]y = 24x + 50[/tex]

Step-by-step explanation:
Identifying a binomial experiment In a study conducted by the sponsoring organization of an academic conference, attendees were classified during registration into one of three categories according to their field of interest: General, Applied, or Theoretical. Of the 400 people in attendance, 200 were classified as General, 60 were classified as Applied, and 140 were classified as Theoretical. You randomly select three registration cards (with replacement) of attendees of the conference and record their fields of interest.
This experiment _________ binomial experiment.
When you select a registration card, the probabilities associated with each outcome are:
Outcome Probability
General 0.35
Applied 0.45
Theoretical 0.20
binomial random variable with mean E(X) = and Let X be the number of card selections with outcome "General." Then X is a standard deviation o =________
Answer:
1, this is a binomial experiment.
Step-by-step explanation:
this is a binomial experiment. Since it is general outcome, the probability of success is 0.50, that is 50 percent.
we have that X follows the binomial distribution
X ~ Binomial(n = 3, p = 0.50)
we have 3 outcomes( general, applied, theoretical).
mean = E(X)
= np
= 3(0.5)
= 1.5
standard deviation = σ = √np(1-p)
= √3(0.5)(1-0.5)
= √1.5(0.50)
= √0.75
= 0.8660
the mean = 1.5
the standard deviation = 0.8660

Answer:
Nathan must order 21 sets of forks for the restaurant.
Step-by-step explanation:
Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:
(571 - 361) / 10 = X
210/10 = X
21 = X
So Nathan must order 21 sets of forks for the restaurant.

Answer:
14 one fourths
Step-by-step explanation:
First, we convert 7/2 into a fraction with the denominator of a four. To do this, we multiply the top and bottom by 2. 7*2 is 14, and 2*2 is 4, which gives us 14/4. This means that there are 14 one fourths in 7/2. Hope this helps!
Answer:
14 fourths
Step-by-step explanation:
Hey There!
So to solve this problem we need to divide 7/2 by 1/4
[tex]\frac{7}{2}divided by\frac{1}{4} =14[/tex]
Therefore 14 fourths can go into 7/2
