At the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music. Of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical. Determine the empirical probability that the next person entering the store favors
(a) rock music.
(b) country music.
(c) something other then rock, country, or classical music.
Answers
Answer:
A) 20%.
B) 26.66%.
C) 40%.
Step-by-step explanation:
Since at the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music, and of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical, to determine the empirical probability that the next person entering the store favors (a) rock music, (b) country music, and (c) something other then rock, country, or classical music, the following calculation must be performed:
A)
60 = 100
12 = X
12 x 100/60 = X
1200/60 = X
20 = X
Therefore, the probability that the next person favors rock music is 20%.
B)
60 = 100
16 = X
16 x 100/60 = X
1600/60 = X
26.66 = X
Therefore, the probability that the next person favors country music is 26.66%.
C)
60 = 100
24 = X
24 x 100 / 60 = X
2400 / 60 = X
40 = X
Therefore, the probability that the next person favors another type of music is 40%.

482 – 412 + 286 - 12 x 204solve
Answers
Answer:
70,176
Step-by-step explanation:
Given that
482 - 412 + 286 - 12 × 204
We need to solve the above equation
= 482 - 412 + 286 - 12 × 204
= 70 + 286 - 12 × 204
= 356 - 12 × 204
= 344 × 204
= 70,176
Hence, the answer to the given equation is 70,176

[tex]\frac{1}{16}[/tex]
Step-by-step explanation:
Answer:
1/16
Step-by-step explanation:
Anytime you divide fractions by whole numbers, remember this:
Same, change, reciprocal (flip)
In the equation:
3/4 / 12
KEEP 3/4 as it is.
CHANGE the division sign to a multiplication sign.
FLIP 12/1 to 1/12.
The final equation: 3/4 x 1/12
3/4 x 1/12 = 3/48
3/48 simplified: 1/16
Therefore, 3/4 / 12 = 1/16

A. Center C and scale factor 4
B. Center A and scale factor 4
C. Center A and scale factor 5
D. Center C and scale factor 5
Answers
Answer:
B.
Step-by-step explanation:
Center is the point that does not change and that point is A. To find the scale factor you just divide the translated length by the original, in this case, 8÷2 which gives a scale factor of 4.

Step-by-step explanation:
4/10 can be made into an equivalent fraction by multiplying each number by 10. This is because we need to change the denominator into 100 and 10x10=100.
10(4/10)=40/100
40/100 is the answer

In a class othe ratio of the number of boys to the number of girls is 5:6.if there are 20 boys in the xlass, how any pupils are in the class
Answers
5:6 is equal to the proportion 20:24. You know that the number of boys is 20, which is 4 times the ratio of boys, so you multiply 6 by 4 to get 24.
Let the number of girls be x.
According to the question,
[tex] \implies \: \dfrac{5}{6} = \dfrac{20}{x} [/tex]
[tex] \implies \: 5x = 20 \times 6[/tex]
[tex] \implies \: 5x = 120[/tex]
[tex] \implies \: x = \cancel\dfrac{120}{5} [/tex]
[tex] \implies \: x = 24[/tex]
[tex] \cal \therefore \: Number \: of \: girls \: are \: 24.[/tex]
Now,
Pupils in the class = Boys + Girls
[tex] \rightarrow20 + 24[/tex]
[tex] \rightarrow44[/tex]
Total number of pupils are 44 .
12. If DH = HE, MBG = (9x – 20) and
MGC = (5x + 28), find mAB.
Answers
Answer:
176degrees
Step-by-step explanation:
Find the diagram attached. From the diagram;
arcGC = = arc BG
5x + 28 = 9x - 20
5x - 9x = -20 28
-4x = -48
x = -48/-4
x = 12
Get <AB
Since <AB = <BC
<BC = arcGC +arc BG
<AB = arcGC+ arc BG
<AB = 5x + 28 + 9x - 20
<AB = 14x + 8
<AB = 14(12) + 8
<AB = 168 + 8
<AB = 176degrees
Hence the arc AB is 176degrees
Round to the nearest hundredth if necessary.

The average size of a new house built in a Hays county in 2010 was 1,872 square feet. A random sample of 40 new homes built in Hays County were selected in 2014. The average square footage was 2,031 with a standard deviation of 373 square feet. Does this sample provide enough evidence to conclude that the average house size has increased in the Hays County since 2010? Test at an alpha level of 0.05. Find the test statistic.
Answers
Answer:
The test statistic is z = 2.7.
The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.
Step-by-step explanation:
The average size of a new house built in a Hays county in 2010 was 1,872 square feet. Evidence that it has increased?
This means that the null hypothesis is:
[tex]H_0: \mu = 1872[/tex]
And the alternate hypothesis is:
[tex]H_a: \mu > 1872[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
1872 is tested at the null hypothesis:
This means that [tex]\mu = 1872[/tex]
Sample of 40. The average square footage was 2,031 with a standard deviation of 373 square feet.
This means that [tex]n = 40, X = 2031, \sigma = 373[/tex]
Value of the test-statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{2031 - 1872}{\frac{373}{\sqrt{40}}}[/tex]
[tex]z = 2.7[/tex]
Pvalue and decision:
The pvalue of the test is the probability of finding a sample mean above 2031. This is 1 subtracted by the pvalue of z = 2.7.
Looking at the z-table, z = 2.7 has a pvalue of 0.9965
1 - 0.9965 = 0.0035
The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.

Area of sector of a circle = 28.26 meter²
Step-by-step explanation:
Given:
Side of cube = 12 meter
One white section = sector of a circle
Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2
Radius of circle = 6 meter
One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
Area of sector of a circle = 28.26 meter²
