Represent the division expression using unit form.
Answer:
I think the question you are trying to say is . . . A baker bought some flower. He used 2/5 of the flour to make bread and used the rest to make batches of muffins. If he used 16lb of flour making bread and 2/3 lb for each batch of muffins, how many batches of muffins did he make?
So I have provided the answer and explanation below.
Step-by-step explanation:
He make 36 batches of muffins.
Consider the provided information.
It is given that he used 2/5 of the flour for bread, and he used 16lbs for bread.
Let total amount of flour is x lbs, now convert above statement into mathematical form.
2/5 x = 16
2x/5 = 16
x = 5 • 16/2 = 80/2
x = 40
Therefore, he bought 40 lbs of flour.
He used 16 lb out of 40.
So for muffins he left with 40-16=24 lbs of flour.
It is given that he used 2/3 lb. For each batch of muffins.
Divide 24 with 2/3 lb.
24/2/3 = 24 • 3/2
72/2 = 36
Hence, he make 36 batches of muffins.
Which set of numbers represents the RANGE for the following table
x -3 4 6 -12
y 5 -6 2 0
A
{−6,0,2,5}
B
{4, 5, 6, 12}
C
{−3,4,6,12}
D
{0, 5, 6, 2}
Answer:
The range of the table is:
Range R = {-6, 0, 2, 5}
Hence, option A is true.
Step-by-step explanation:
Given the table
x -3 4 6 -12
y 5 -6 2 0
Determining the range:
We know that the range of a table consists of all the y-values of the given points.
From the given table, it is clear that the y-values are:
y = 5, -6, 2, 0
Thus, the range of the relation in ascending order is:
Range R = {-6, 0, 2, 5}
Please note that the duplicated elements in the range, if any, are written only once.
Therefore, the range of the table is:
Range R = {-6, 0, 2, 5}
Hence, option A is true.

Prove that segment DE is parallel to segment AB.
Answer:
Proof below
Step-by-step explanation:
To prove DE and AB are parallel, we compare the slopes of both segments
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Segment AB goes through the points (0,0) and (x2,0), thus:
[tex]\displaystyle m_{AB}=\frac{0-0}{x_2-0}=0[/tex]
The slope is 0 because the line is horizontal.
Now for the segment DE, the endpoints are
[tex]\displaystyle (\frac{x_1}{2},\frac{y_1}{2}),\ (\frac{x_1+x_2}{2},\frac{y_1}{2})[/tex]
The slope is:
[tex]\displaystyle m_{DE}=\frac{\frac{y_1}{2}-\frac{y_1}{2}}{\frac{x_1+x_2}{2}-\frac{x_1}{2}}[/tex]
[tex]\displaystyle m_{DE}=\frac{0}{\frac{x_2}{2}}=0[/tex]
Segment DE is also horizontal, thus is parallel to segment AB.

The ground temperature at an airport is 11 °C. The temperature decreases by 6.4 °C for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?
Answer:
-21°C
Step-by-step explanation:
Since the plane is flying at an altitude of 5 kilometers, then we have to multiply 6.4 by each kilometer that the plane's altitude increased (5). After that, we will end up with 32°C that we have to subtract from the ground temperature of 11°C. Once we do that, we get -21°C which means that the temperature at an altitude of 5 kilometers is -21°C.

Assume that X is Normal with mean $ 240 and standard deviation $60 . the probability that , in a randomly selected week , Dan will make less than $ 255
Answer:
The probability of Dan making less than $255 is 0.5987 or 59.87%
Step-by-step explanation:
Given that:
Mean = μ = $240
SD = σ = $60
We have to find the probability that Dan will make less than $255
First of all, we have to find the z-score of 255
z-score is denoted by z and is given by the formula
[tex]z = \frac{x-mean}{SD}[/tex]
Here,
x = 255
Putting the values
[tex]z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25[/tex]
Now we have to look at the z-score table to find the probability of 0.25
P(x<255) = 0.5987
Converting into percentage
59.87%
Hence,
The probability of Dan making less than $255 is 0.5987 or 59.87%
A student borrows a total of $5400 in student loan from two lenders. Bank One charges 4.3% simple
interest and Bank Two charges 5.9% simple interest. She is not required to pay off the principal for 3
years. However, at the end of three years, she will owe a total of $888.60 for interest from both loans.
How much did she borrow from Bank One?
non
9514 1404 393
Answer:
$1400
Step-by-step explanation:
Let x represent the amount borrowed from Bank 1. For each loan, the interest is given by I=Prt, where P is the principal borrowed at rate r for t years.
Then the total interest over 3 years is ...
3(4.3%·x +5.9%(5400 -x)) = 888.60
-1.6%·x +318.60 = 296.20 . . . . . . . . . . . divide by 3, simplify
-1.6%·x = -22.40 . . . . . . . . . . . subtract 318.60
x = 22.40/0.016 = 1400
The student borrowed $1400 from Bank 1.

Teen Court is a juvenile diversion program designed to circumvent the formal processing of first-time juvenile offenders within the juvenile justice system. An article reported on a study in which offenders were randomly assigned either to Teen Court or to the traditional Department of Juvenile Services method of processing. Of the 57 Teen Court individuals, 18 subsequently recidivated during the 18-month follow-up period, whereas 11 of the 54 Department of Juvenile Services individuals did so. Does the data suggest that the true proportion of Teen Court individuals who recidivate during the specified follow-up period differs from the proportion of Department of Juvenile Services individuals who do so
Answer:
Z-statistic = 1.4017 < 1.96 at 0.05 level of significance
Null hypothesis is accepted
The data suggest that the true proportion of Teen Court individuals who recidivate during the specified follow-up period differs from the proportion of Department of Juvenile Services individuals
Step-by-step explanation:
Step(i):-
Given first sample size (n₁ ) = 57
Of the 57 Teen Court individuals, 18 subsequently recidivated during the 18-month follow-up period
First sample proportion
[tex]p^{-} _{1} = \frac{x_{1} }{n_{1} } = \frac{18}{57} =0.3157[/tex]
Second sample proportion
[tex]p^{-} _{2} = \frac{x_{2} }{n_{2} } = \frac{11}{54} =0.2037[/tex]
Null Hypothesis : p₁⁻ = p₂⁻
Alternative Hypothesis : p₁⁻ ≠ p₂⁻
Step(ii):-
Test statistic
[tex]Z = \frac{p_{1} ^{-} -p^{-} _{2} }{\sqrt{PQ(\frac{1}{n_{1} } +\frac{1}{n_{2} } )} }[/tex]
where
[tex]P = \frac{n_{1}p^{-} _{1} +n_{2} p^{-} _{2} }{n_{1} +n_{2} }[/tex]
[tex]P = \frac{57 X0.3157+0.2037X54}{54+57} = 0.2612[/tex]
Q = 1 - P = 1 - 0.2612 = 0.7387
[tex]Z = \frac{0.3157-0.2037}{\sqrt{0.2612 X0.7387 (\frac{1}{57} +\frac{1}{54} )} }[/tex]
Z = 1.4017
Level of significance ∝ =0.05
The tabulated value Z₀.₀₅ = 1.96
Z-statistic = 1.4017 < 1.96 at 0.05 level of significance
Null hypothesis is accepted
The data suggest that the true proportion of Teen Court individuals who recidivate during the specified follow-up period differs from the proportion of Department of Juvenile Services individuals

Answer:
Store A
Step-by-step explanation:
Store A: 5% of 50 is 2.5. If we subtract the discount from the original price, we get $47.50 as the discounted price
Store B: 20% of 60 is 12. If we subtract the discount from the original price, we get $48 as the discounted price
47.50 < 48
(hope this helps)
Answer:
Store A
Step-by-step explanation:
5% of $50 is $2.50, which means that store A is $2.50 off.
20% of 60 is %12, which means store B is $12.00 off.
However, store A has an original price that is $10 less than store A, and if you do $50 - $2.50 = $47.50 and Store B's price equals out to $60 - $12 - $48.00
this means that the full price with discount is lower for store A than it is for store B

Step-by-step explanation:
Sales personnel for Skillings Distributors submit weekly reports listing the customer contacts made during the week. A sample of 35 weekly reports showed a sample mean of 19.5 customer contacts per week. The population standard deviation was 5.2. Provide a 99% confidence interval for the population mean number of weekly customer contacts for the sales personnel.
Answer:
The answer is below
Step-by-step explanation:
Given that:
Confidence interval (C) = 99%, mean (μ) = 19.5, standard deviation (σ) = 5.2, sample size (n) = 35
α = 1 - C = 1 - 0.99 = 0.01
α/2 = 0.005
The z score of α/2 (0.005) is the same as the z score 0.495 (0.5 - 0.005) which is equal to 2.576.
The margin of error (E) is given as:
[tex]E=Z_\frac{\alpha}{2}*\frac{\sigma}{\sqrt{n} } \\\\E=2.576*\frac{5.2}{\sqrt{35} } \\\\E=2.264[/tex]
The confidence interval = (μ ± E) = (19.5 ± 2.264) = (17.236, 21.764).
The confidence interval is between 17.236 and 21.764.

the difference of the
ages of two brothers is 4 years 5 years ago if the product of their ages was 96 find their present ages
Answer:
OB - Older Brother
YB - Younger Brother
A) OB -YB = 4
B) OB * YB = 96
B) OB = 96 / YB
Multiplying A) by -1
A) -OB + YB = -4 then we add B)
B) OB = 96 / YB
YB = -4 + 96 / YB
Multiplying both sides by YB
YB^2 = -4YB +96 then re-arranging
YB^2 + 4YB -96 = 0 solving by quadratic equation
AS OF 5 years AGO:
Younger Brother's age = 8
Older Brother's age = 12
NOW THEIR AGES ARE:
8 + 4 = 12 YB and
12 + 4 = 16 OB

Determine the next three terms in the following sequence: -1, 1/2, - 1/4, 1/8
Answer:
-1/16, 1/32, and -1/64.
Step-by-step explanation:
Basically, all you have to do is find the pattern in the sequence in front, which in this case is division by -2. Hence, you can apply this onwards to get (1/8) / -2 = -1/16, (-1/16) / -2 = 1/32, and (1/32) / -2 = -1/64.
Hope this helped! Merry Christmas!
