Step-by-step explanation:
Carey creates the table to him determine 75% of 36
The table made is correct, so we conclude that 3/4 is equivalent of 75%. However, we must apply this percentage, or fraction, to the whole number we want to take the percentage of, that is, 36.
The number 27 is the actuall result of taking this percentage.
So, the correct expression would be:
[tex](\frac{3}{4})(36)[/tex]Thus, we need to change the 27 to 36, first alternative.
You're having a breakfast party for 483 of your closet friends and 271 like chocolate donuts. In a dozen donuts, the probability of getting a chocolate donut is 1/5. How many dozen donuts would you have to buy to ensure that all 271 people get a chocolate donut?
In a dozen donuts the probability of getting a chocolate donut is 1/5, meaning 1/5 of the 12 donuts are chocolate donuts.
Step 1.- Calculate how much 1/5 out of 12 is:
[tex]\frac{1}{5}(12)=\frac{12}{5}=2.4[/tex]In each dozen we would get 2.4 chocolate donuts
Step 2.- Calculate how many dozen are needed to get 271 chocolate donuts.
We divide 271 by 2.4 to get the answer:
[tex]\frac{271}{2.4}=112.92[/tex]Step 3: We round the answer to the nearest integer value, and we need 113 dozens of donuts to ensure that all 271 people get a chocolate donut.

When finding the composition of f (g (x) )substitute f (x) for the x in g (x)multiply f (x) by g (x)substitute g (x) for the x in f (x)
Okay, here we have this:
Considering that the composition of function is formed by taking the outputs of one function and converting them into the inputs of another function. We obtain that, f(g(x)), consists of taking the result obtained by evaluating g (x) and replacing it by x in f (x). Then the correct answer is the third option.

[tex]\begin{gathered} \frac{x}{2.1}=\frac{36000}{100} \\ x=\frac{36000\cdot2.1}{100} \\ x=756 \end{gathered}[/tex]That corresponds to the cost of living increase.
Try AgainAt the city museum, child admission is $6.00 and adult admission is $9.20. On Monday, twice as many adult tickets as childtickets were sold, for a total sales of $780.80. How many child tickets were sold that day?
32 child tickets were sold on that day
Explanation:Given:
The cost per child = $6.00
let the number of child tickets = c
The cost per adult ticket = $9.20
let the number of adult tickets = a
To find:
the number of child tickets sold
On Monday:
Adult tickets = 2(children tickets)
a = 2c
Total sales on Monday = $780.80
Total sales = The cost per child (number of child tickets) + The cost per adult (number of adults tickets)
780.80 = 6(c) + 9.2(a)
substitute for a:
780.8 = 6c + 9.2(2c)
780.8 = 6c + 18.4c
780.8 = 24.4c
divide both sides by 24.4:
[tex]\begin{gathered} \frac{780.8}{24.4}\text{ = }\frac{24.4c}{24.4} \\ \\ c\text{ = 32} \end{gathered}[/tex]Hence, 32 child tickets were sold on that day

What is a rectangle?
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
The total length of the side of the rectangle that has four patio pavers is sixty-three and two-tenths inches.
This means,
Length of the side with 4 patio pavers.
= 63(2/10) inches
= 632/10
= 63.2 inches
Now,
The length of one patio paver.
4 patio pavers = 63.2 inches
Divide both sides by 4.
1 patio pavers = 63.2/4
1 patio pavers = 15.8 inches.
Thus,
The length of one patio paver is 15.8 inches.

Answer:
The approximate value of the car after 7 years is;
[tex]\text{ \$9,565.94}[/tex]Explanation:
Given that the initial value of the car is;
[tex]P=\text{ \$20,000}[/tex]after 1 year its new value is;

Hudson uses a container in the shape of a right cylinder with a radius of 7.3 cm and a height of 12.2 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Hudson collected? Round your answer to the nearest tenth.
We have a water that has a concentration of 0.036 grams per cm³ of some trace element.
We have to find how much of this trace element will be in the container with the sample of water.
This amount will be equal to the volume of the container times the concentration of the trace element.
We start by calculating the volume.
The container is a cylinder. Its volume will be the base area times the height.
We can calculate it as:
[tex]\begin{gathered} V=A_bh \\ V=(\pi r^2)h \\ V=\pi(7.3)^2(12.2) \\ V=\pi(53.29)(12.2) \\ V\approx2042.4688\text{ }cm^3 \end{gathered}[/tex]We can multiply this volume by the concentration as:

What is the purchase price of a 50-day T-bill with a maturity value of S1,737 that eams an annual interest rate of 2 802% (Assume a 360 day year)The purchase price is (Round to two decimal places)
We need to use the next simple interest formula:
[tex]A=P(1+rt)[/tex]Where
P= Present value
r= annual interest rate in decimal form
T=time in years
A=amount after time

The given frequency distribution table is given .
Using the data from the table we have to find the mean
We know that :
Mean = sum of all data/ total frequency.
From the table we see that
Mean = 52 + 7 × 5 /37 = 52.94
Standard deviation:
The formula for calculating this is given by:
[tex]{\displaystyle s_{N}={\sqrt {{\frac {1}{N}}\sum _{i=1}^{N}\left(x_{i}-{\bar {x}}\right)^{2}}}.}[/tex]
substituting the values we get :
sd = √(73.67/37)×5
sd = 7.0056
sd ≈ 7.01
When that is not possible, the standard deviation is determined by analysing a sample of the population that is representative of the entire population and creating a statistic that is used to estimate the standard deviation of the population as a whole.
This type of statistic is called an estimator, and the estimator itself is known as a sample standard deviation .
Hence the mean of the grouped data is 52.94 and the standard deviation is 7.01 .
