QUESTION POSTED AT 14/12/2019 - 06:05 PM

Please help me answer this ASAP! The two-way table shows the number of ninth and tenth graders who prefer going to sporting events or going to the movies. Among tenth graders, what is the relative frequency of preferring sporting events? Express your answer as a decimal, and round to the nearest hundredth if necessary

Answer

0.43

Explanation

Remember that RelativeFrecuency=\frac{Frecuency}{SumOfAllFrecuencies}

Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so Frecuency=6. Now, the sum of all frequencies will be the sum of all the 10th graders, so SumOfAllFrecuencies=6+8=14. Let's replace the values:

RelativeFrecuency=\frac{Frecuency}{SumOfAllFrecuencies}

RelativeFrecuency=\frac{6}{14}

RelativeFrecuency=0.4285

And rounded to the nearest hundredth:

RelativeFrecuency=0.43

QUESTION POSTED AT 14/12/2019 - 05:57 PM

Please help with mathematics

First question:-

Order from least to smallest.

9,3, 9 1/3, 37/4, 9.34

Now, let us get all the numbers in the same format.

37/4 = 9  1/4

9 1/4 = 9.25

9.34 

9.3 = 9.30

9 1/3 = 9.33

Now order them.

Final answer:   37/4, 9.3, 9 1/3, 9.34     DONE!

Second question:- 

6 1/2 + 5 1/5   =    6  5/10 + 5  2/10  =   11   7/10

11   7/10  +  2   4/5   =  11  7/10 +  2  8/10  =  13  15/10   =  14 1/2

14.5 =  n + 10 

Now solve for n

14.5 - 10 = n + 10
               -10

4.5 = n 

Final answer:    n = 4  1/2 


Third question:-

Reciprocity of 1 1/2

first, we make the mixed number an improper fraction.

1 1/2  =  1*2 = 2 + 1 = 3

3/2  the reciprocal of it is 2/3

Final answer: 2/3

Fourth question:- 

solve the proportion.

2 2/5 minutes to run 1.5 miles.

2.4/1.5 = 1/x

Cross multiply.      2.4*x = 1.5*1

2.4x = 1.5
-------------
   2.4

x = 2.4/1.5

Final answer:    x= 1  3/5

Fifth question:-

x/10 = 2 2/10        <--------- i made sure the denom's are the same!

22/10 = x/10 

x = 22

Final answer: x = 22

YES...WE HAVE OUR ANSWERS...AND THIS TOOK ME FOREVER. :D

Identify the arc length of TV in terms of π. (image is attached) The answers for this question were: ≈0.67pi in., ≈1.83pi in., ≈3.67pi in., or ≈1.33pi in.

Use the formula of arc length that is
s = rθ
where s = arc length, r = radius, θ = angle (unit must be in radian)
Given r = 5 in and θ = 48°( π /180°) = (4/15)* π = 0.2667 π,
s = 5 in (0.2667π) = 1.333 π in

QUESTION POSTED AT 14/12/2019 - 05:50 PM

6d 1 = 15-d I really don't understand thisssss and my teacher won't help

You required to find the value of d.
Always remember the concept that if you transpose "+" sign to the other side, it becomes "-" sign, and vice versa. Make sure that you arrange the like terms and constants. Solving the equation,
6d + 1 = 15 - d
6d + d = 15 - 1
7d = 14
d = 14/7 = 2

When transposing a multiplication, you divide it to the other side.

Verifying the solution,
6(2) + 1 = 15 - 2
12 + 1 = 13
13 = 13

QUESTION POSTED AT 14/12/2019 - 05:50 PM

A merry-go-round has a radius of 10 ft. To the nearest tenth of a foot, what distance does the merry-go-round cover when it rotates through an angle of 72°? For my first try, I got 62.9 as my answer, and it was marked wrong. I did this a second time, and got 12.6. I would like to check with anyone else to see if I got the answer right. The answers for this question were: 62.9, 12.6, 25.1, or 125.7

Yes, the correct answer is 12.6 ft.

Using the formula of arc length, that is
s = rθ
where s = arc length, r = radius, θ = angle (unit must be in radian)
With r = 10 ft and θ = 72 deg ( π/180 deg) = 1.26 rad,
s = (10)(1.26) = 12.6 ft

QUESTION POSTED AT 14/12/2019 - 05:50 PM

How does the definition of percent help you write fraction and decimal equivalents

A percent is a ratio of a number to 100. It is often used to communicate a relative amount. Per cent means "per 100".

12% means 12 out of 100 or 12/100 in fraction or 0.12 in decimal equivalents.

If a percentage is converted into a fraction without a whole number given, the denominator is always 100 and the fraction can be simplified by dividing both numerator and denominator by the common factor.
Example:
25% becomes 25 / 100. It can be simplified to 1 / 4.

If a percentage is converted into a decimal, based from the percent sign (%) move the decimal point to places to the left.

Example:
25% becomes  0.25  two places to the left from the % sign.
OR
125% becomes 1.25

To find f(4), you just replace wherever x is with 4.

f(x) = 3x - 1
⇒ f(4) = 3*(4) - 1
⇒ f(4)= 12-1
⇒ f(4)= 11.

f(4) = 11 is the final answer.

What is the solution to the equation? 4x - 26 - 3x = 16 - 20 (I got my answer as 22, and that was correct, but I had completely forgotten how I did it. Help please)

Question:  4x - 26 - 3x = 16 - 20

Answer and Explanation:- 

First, we combine like terms.

4x - 3x = x

Now, rewrite the equation.

x - 26 = 16 - 20

16 - 20 = -4

x - 26 = -4
  
Apply the inverse operation.

x - 26 = -4
   +26    +26

x = 22

Final answer: x equals 22, so the solution is 22.
