Reason:
The numerator is [tex](2.1)^5[/tex]
Raising that to the third power gives
[tex]((2.1)^5)^3 = (2.1)^{5*3} = (2.1)^{15}[/tex]
We multiply the exponents. The general rule is
[tex](a^b)^c = a^{b*c}[/tex]
Use that same rule to cube the denominator.
[tex]((0.9)^4)^3 = (0.9)^{4*3} = (0.9)^{12}[/tex]
Therefore,
[tex]\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{((2.1)^5)^3}{((0.9)^4)^3}\\\\=\frac{(2.1)^{5*3}}{(0.9)^{4*3}}\\\\=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\[/tex]
In short

A histogram shows the number of magazines read last month by the students in a class. What percent of the students read less than six magazines?
can you find the mean and median of the data? Explain.
Answers
This is because there are 20 students (all frequency numbers added 15+3+2=20) and 17 if those 20 read less than 6 so
17/20=0.85
0.85(100)=85%
You can not find the mean number of magazines read because it is the middle number but the numbers are given in ranges.
You can not find the median because it is the total total number magazines read divided by number of students and you once again can't find the exact number of magazines because they are in ranges.
74% percent of the students read less than six magazines
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
A histogram shows the number of magazines read last month by the students in a class
The total number of students are 2+15+3
Number of students=23
Number of students read less than six magazines is 17
Now let us find 17 is what percent of 23
x/100×23=17
23x=1700
Divide both sides by 23
x=1700/23
x=73.9
x=74%
Hence, 74% percent of the students read less than six magazines

Answer:
163/40
Step-by-step explanation:
multiply 4x40
then add 3
= 163
then put it over 40
163/40
Answer:
To simplify 4 3/40, we need to convert the mixed number to an improper fraction and then simplify:
4 3/40 = (4 × 40 + 3) / 40 (convert to improper fraction)
= 163 / 40
Now, we can simplify this fraction by finding the greatest common factor (GCF) of the numerator and denominator, which is 1:
163 / 40 = (163 ÷ 1) / (40 ÷ 1)
= 163 / 40
Therefore, 4 3/40 in simplest form is 163/40.

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player. Josiah predicted the number of rock songs on his MP3 player to be 300 songs. Which statements about his solution are true? Select three choices. Josiah’s Music Sample 1 Sample 2 R & B 5 R & B 4 Pop 4 Pop 3 Classical 3 Classical 5 Jazz 2 Jazz 4 Rock 6 Rock 4 Josiah’s work: StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x. He should have found the average of the number of rock songs by averaging 4 and 6 to get 5. He did not multiply the numerator and denominator by the correct number to equal 1,500. His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion. He can only solve the proportion by multiplying the numerator and denominator by a common multiple. He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500
Answers
Answer:
Answer is B)
Step-by-step explanation:
Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500
The proportion is given as:
Multiply both sides by 1500
Evaluate the expression on the right-hand side
Multiply 10 by 1500 on the left-hand side
Divide 15000 by 20 on the left-hand side
Rewrite the equation as:
From the question, we can see that the products are not well carried out.
Hence, Josiah's mistake is (b)
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.
What is Fraction ?What is fraction and example?
A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts
Types of Fractions Proper fraction,Improper fraction,Mixed fraction,Like fractions,Unlike fractions,Equivalent fractions.
The statements that are true about Josiah's solution are:
He correctly found the proportion of rock songs by setting the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:
Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.
Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.
300 = x.
He didn't hit the average of the rock songs right because the average of 4 and 6 is 5, not 300.
He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:
Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.

A circular circus tent has a diameter of 5 meters. What is the approximate area of the floor of the circus tent? Use 3.14 for pi.
Answers
Answer:
[tex]\text{A}=19.6 \ \text{m}^2[/tex]
Explanation:
We are given a circular circus tent
diameter = 5m
we know that
[tex]\text{radius}=\dfrac{\text{diameter}}{2}[/tex]
[tex]\text{radius}=\dfrac{\text{5}}{2}[/tex]
[tex]\text{radius}=2.5[/tex]
so, [tex]\text{r}=2.5[/tex]
now, we can use area formula
[tex]\text{A}=3.14(\text{r})^2[/tex]
now, we can plug values
[tex]\text{A}=3.14(\text{2.5})^2[/tex]
[tex]\text{A}=19.625[/tex]
so,
[tex]\text{A}=19.6 \ \text{m}^2[/tex]
Answer:
Step-by-step explanation:
The approximate area of the floor of the circus tent is 19.625 square metres.
The area to be found is that of a circle. The data given in the question is
the diameter of the circle. To calculate the area of the circle, we need to first find the radius. The radius is half of the diameter. By calculation, d/2, we get 5/2= 2.5m. The formula for finding the area of the circle is πR². By substituting the values, we get A(Area) = 3.14 (given) * 2.5 * 2.5 square metres. The area comes out to be 19.625 square metres.

Answer: 76.5
Step-by-step explanation: First of all, you should divide all of the shapes into 1 shape. That leaves you with 3 separate shapes to find the area to. First, let's start at the bottom rectangle. The area of that rectangle is 42. Now, lets to the middle rectangle. 4x7=28, which is the area of that rectangle. Now, we do the triangle. We have to find out the side length, but we know that the bottom length is 13. So, we add 6+7 to get that specific length (13). Because this shape is a triangle, we divide 13 by 2 (6.5). Finally, we add 42+28+6.5, and we get 76.5. Hope this helped!
