A survey was conducted among 400 students of age
groups 7-12 years and 13-18 years to find their
favorite music genre. The students had to select any
one genre out of jazz, rock, and pop. Out of the 200
students in the age group 7-12 years who participated
in the survey, 142 liked rock or pop music. The total
number of students of both age groups who liked jazz
was 72.
Using a two-way table, compute the total number of
students in the age group 13-18 years who liked rock
or pop music.

Answers

Answer 1

Answer:  186

Step-by-step explanation:

                     Jazz                      Rock or Pop  

7-12:          200 - 142 = 58                  142

13-18:        72 - 58 = 14                200 - 14 = 186

It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.

Therefore, 200-142 = 58 in that age group like Jazz.

Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.

There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18.  200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.

The claim that the mean amount of sleep for adults is less than 7 hours. Choose the correct statement about null and alternative hypothesis.
a) H0: µ > 7 hours (null hypothesis)

c) H0: µ = 7 hours (null hypothesis)
H1: µ < 7 hours (alternative hypothesis and original claim)
d) H0: µ < 7 hours (null hypothesis)
H1: µ ≥≥ 7 hours (alternative hypothesis and original claim)

Answers

Answer:

c) H0: µ = 7 hours (null hypothesis)

H1: µ < 7 hours (alternative hypothesis and original claim)

Step-by-step explanation:

The hypothesis test is performed in order to see if a sample outcome gives evidence to reject a null hypothesis and support the researchers claim.

In this case, the claim is that the mean amount of sleep for adults is less than 7 hours.

For this claim, the alternative hypothesis will state the researcher's claim: the mean amount of sleep for adults is significantly less than 7 hours.

The null hypothesis will state the opposite: the mean amount of sleep for adults is not significantly less than 7 hours. In this case, it is the same to claim that the mean amount is 7 hours.

Then, the null and alternative hypothesis are:

p is a rectangle with lengths 60cm and width x cm q is a rectangle with width y cm. the length of q is 20% more than the length of p the area of p is 15% less than the area of q work out the ratio x:y

Answers

Answer:

The ratio of x to y is

1.02/1 = x/y

1.02:1= x:y

Step-by-step explanation:

Rectangle p

Length = 60 cm

Width = x cm

Area = length* breadth

Area = 60 *x

Rectangle q

Length = 20% more than length of rectangle p

Length = (60*0.2) + 60

Length = 12 +60

Length = 72cm

Width = y cm

Area = 72*y

(72*y)-(72*y *0.15)= 60*x

72y - 10.8y = 60x

61.2y = 60x

61.2/60 = x/y

15.3/15= x/y

5.1/5 = x/y

1.02/1 = x/y

According to a polling​ organization, 22% of adults in a large region consider themselves to be liberal. A survey asked 200 respondents to disclose their political​ philosophy: Conservative,​Liberal, And Moderate. Treat the results of the survey as a random sample of adults in this region. Do the survey results suggest the proportion is higher than that reported by the polling​organization? Use an alpha =0.05 level of significance.
75- Liberal
65- Moderate
61- Conservative

Answers

Answer:

Step-by-step explanation:

Using the proportion test

Null hypothesis: p <= 0.22

Alternative hypothesis: p > 0.22

Using the formula

z score = p - P /√ (P(1-P)/n)

Where p is 74/200= 0.37, P = 0.22, n = 200.

0.37-0.22 / √(0.22(1-0.22)/200)

0.15 / √(0.22(0.78)/200)

0.15 / √(0.1716/200)

0.15/ √0.000858

0.15 / 0.02929

= 5.1212

To help arrive at a conclusion, we have to find the p value, using a p value calculator at the 0.05 level of significant, the p value is less than 0.00001... Thus we would reject the null as there is sufficient statistical evidence to prove that the proportion is higher than that reported by the polling ​organization.

Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antiderivative.) f(x) = 8x3/5 + 3x−4/5

Answers

Answer:

[tex]\dfrac{8x^{4}}{20}+\dfrac{3x^{2}}{2}-\dfrac{4}{5}x+C[/tex]

Step-by-step explanation:

Given the function: [tex]f(x)=\dfrac{8x^3}{5}+3x-\dfrac{4}{5}[/tex]

To take the antiderivative (or integral) of a function, we follow the format below.

[tex]f(x)=x^n\\$Then its antiderivative\\Antiderivative of f(x)$=\dfrac{x^{n+1}}{n+1}[/tex]

Therefore, the antiderivative of f(x) is:

We want to check our result by differentiation.

[tex]\dfrac{d}{dx}\left(\dfrac{8x^{4}}{20}+\dfrac{3x^{2}}{2}-\dfrac{4}{5}x+C\right)\\=\dfrac{d}{dx}\left(\dfrac{8x^{4}}{20}\right)+\dfrac{d}{dx}\left(\dfrac{3x^{2}}{2}\right)-\dfrac{d}{dx}\left(\dfrac{4}{5}x\right)+\dfrac{d}{dx}\left(C\right)\\\\=\dfrac{32x^{3}}{20}+\dfrac{6x}{2}-\dfrac{4}{5}+0\\\\=\dfrac{8x^{3}}{5}+3x-\dfrac{4}{5}[/tex]

Answer: Hope this helps <3

Step-by-step explanation:

Graphs can be used to represent functions.

See attachment for the graphs of [tex]\mathbf{x^2 + y = 2}[/tex] and [tex]\mathbf{x^2 + y^2 = 9}[/tex]

The functions are given as:

[tex]\mathbf{x^2 + y = 2}[/tex]

[tex]\mathbf{x^2 + y^2 = 9}[/tex]

Rewrite [tex]\mathbf{x^2 + y^2 = 9}[/tex] as:

[tex]\mathbf{x^2 + y^2 = 3^2}[/tex]

The above equation represents a circle of radius 3, and that has its center as the origin.

Similarly, we have:

[tex]\mathbf{x^2 + y = 2}[/tex]

Make y the subject

[tex]\mathbf{y = 2 -x^2}[/tex]

Rewrite as:

[tex]\mathbf{y = -x^2 + 2 }[/tex]

The above is a square function, that is reflected over the y-axis, and then shifted up by 2 units.

A model for​ consumers' response to advertising is given by the equation N(a)=2600 + 470ln (a) Where​ N(a) is the number of units​ sold, a is the amount spent on​ advertising, in thousands of​ dollars, & a≥1.

Required:
a. How many units were sold after spending ​$1,000 on​ advertising?
b. Find N′(a).
c. Find the maximum​ value, if it exists.
d. Find lim a→[infinity] N′(a).

Answers

Answer:

a. [tex]N(1)=2600[/tex]

b. [tex]N'(a) = 470/a[/tex]

c. N(a) has no maximum value, max N'(a) = 470 (when a = 1)

d. lim a→[infinity] N′(a) = 0

Step-by-step explanation:

a.

the variable 'a' is the amount spent in thousands of dollars, so $1,000 is equivalent to a = 1. Then, we have that:

[tex]N(1)=2600 + 470ln(1)[/tex]

[tex]N(1)=2600 + 470*0[/tex]

[tex]N(1)=2600[/tex]

b.

To find the derivative of N(a), we need to know that the derivative of ln(x) is equal (1/x), and the derivative of a constant is zero. Then, we have:

[tex]N'(a) = 2600' + (470ln(a))'[/tex]

[tex]N'(a) = 0 + 470*(1/a)[/tex]

[tex]N'(a) = 470/a[/tex]

c.

The value of 'ln(a)' increases as the value of 'a' increases from 1 to infinity, so there isn't a maximum value for N(a).

The maximum value of N'(a) is when the value of a is the lower possible, because 'a' is in the denominator, so the maximum value of N'(a) is 470, when a = 1.

d.

When the value of 'a' increases, the fraction '470/a' decreases towards zero, so the limit of N'(a) when 'a' tends to infinity is zero.

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

where a and b are the legs and c is the hypotenuse.

6 and 16 are the legs, because they form the right angle. c is the hypotenuse because it is opposite the right angle.

[tex]6^2+16^2=c^2[/tex]

Evaluate the exponents.

6^2= 6*6= 36

16^2= 16*16= 256

[tex]36+256=c^2[/tex]

Add 36 and 256.

[tex]292=c^2[/tex]

Since c is being squared, take the square root of both sides of the equation. The exponent and square root will cancel and leave c by itself

[tex]\sqrt{292} =\sqrt{c^2}[/tex]

[tex]\sqrt{292}=c[/tex]

[tex]17.0880075=c[/tex]

Round to the nearest tenth. The 8 in the hundredeth place tells us to roung the 0 in the tenth place up to a 1.

Determine whether the sequence converges or diverges. If it converges, find the limit. an = 9 + 14n2 n + 15n2 Step 1 To find lim n → [infinity] 9 + 14n2 n + 15n2 , divide the numerator and denominator by the highest power of n that occurs in the fraction. This is n .

Answers

Answer:

The sequence Converges

Step-by-step explanation:

Given the sequence [tex]a_n = \frac{9+14n^{2} }{n+15n^{2} }[/tex]

To find the limit of the sequence, we will first divide the numerator and the denominator through by the highest power of n which is n² as shown;

[tex]\lim_{n \to \infty} \frac{9/n^{2} +14n^{2}/n^{2} }{n/n^{2} +15n^{2}/n^{2} }\\ \lim_{n \to \infty} \frac{9/n^{2} +14 }{1/n +15n^{2}/n^{2 }}\\[/tex]

As [tex]n[/tex] tends to [tex]\infty[/tex], [tex]\frac{a}{n}[/tex] tends to zero where n is any constant, The limit of tyhe sequence as n tends to infinity becomes;

[tex]= \frac{9/\infty+14 }{1/\infty+15 }\\= \frac{0+14}{0+15} \\= 14/15\\[/tex]

Therefore [tex]\lim_{n \to \infty} \frac{9+14n^{2} }{n+15n^{2} } = 14/15[/tex]

Since the limit of the sequence gave a finite number , the sequence converges.

Note that the only case when the sequence diverges id when the limit of the sequence is infinite

Consider a data set containing the following values:

The mean of the preceding values is:

70.75.

The deviations for the mean have been calculated as follows:

-0.75, -5.75, 0.25,7.25,18.25,-2.75,-20.75, and 4.25

a. If this is the sample data, the sample variance is _____ and the sample standard deviation is ___
b. If this is a population data, the population variance is_____ and the population standard deviation is_____

Answers

Answer:

a. 125.0714; 11.1835.

b. 109.4375; 10.4612.

Step-by-step explanation:

Given the following data;

70, 65, 71, 78, 89, 68, 50, 75.

Mean = 70.75

The deviation for the mean of the data is -0.75, -5.75, 0.25,7.25,18.25,-2.75,-20.75, and 4.25.

We would then find the square of this deviation;

[tex]=(-0.75)^2+(-5.75)^2+( 0.25)^2+(7.25)^2 +(18.25)^2+(-2.75)^2+(-20.75)^2 +(4.25)^2[/tex]

[tex]=0.5625+33.0625+0.0625+52.5625+333.0625+7.5625+430.5625+18.0625[/tex]

= 875.5

Next is to find the population variance;

[tex]V = \frac{875.5}{8}[/tex]

Variance, V = 109.4375

The population standard deviation is the square root of the population variance;

[tex]Sd = \sqrt{109.4375}[/tex]

Standard deviation, Sd = 10.4612

To find the sample variance;

[tex]V = \frac{875.5}{8-1}[/tex]

[tex]V = \frac{875.5}{7}[/tex]

Variance, V = 125.0714

The sample variance is;

[tex]Sd = \sqrt{125.0714}[/tex]

Standard deviation, Sd = 11.1835

Therefore,

a. The sample variance is 125.0714 and the sample standard deviation is 11.1835.

b. If this is a population data, the population variance is 109.4375 and the population standard deviation is 10.4612.

Hey there! :)

Answer:

f(15) = 29 ft.

Step-by-step explanation:

We can write an arithmatic equation for this pattern:

Where:

[tex]n_{1}[/tex] = 1, [tex]n_{2}[/tex] = 3

Find the rate of change. This is constant because this is an arithmatic sequence.

3 - 1 = 2.

We can begin to write an explicit function for this situation:

f(n) = [tex]n_{1}[/tex] + d(n-1) where d is the rate of change:

f(n) = 1 + 2(n-1)

Substitute 15 for n to solve for the distance traveled after 15 seconds:

f(15) = 1 + 2(15-1)

f(15) = 1 + 2(14)

f(15) = 1 + 28

f(15) = 29 ft.

Therefore, the distance traveled after 15 seconds is 29 ft.

Step-by-step explanation:

Given the equality y > -½, it means the values of y is greater than -½.

The values of y would range from 0 upwards. I.e. 0, ½, 1, 1½, 2. . .

Thus, when graphed on a number line, the circle that appears like "o" would start from -½, and the "o" would not be full or shaded to indicate that -½ is not included in the values of y, which are greater than -½. Since the values of y are greater than -½ the direction of the arrow that indicates values of y would point towards our far right, to indicate the values included as y.

Therefore, the graph that indicates the inequality y > ½ is A

LJ = 3.5

Step-by-step explanation:

To find LJ we use the sine rule

From the picture

LK / sin J = LJ / sin K

LK = 9

J = 89°

K = 23°

So now LJ is

9 / sin 89° = LJ / sin 23°

Make LJ the subject

That's

LJ = 9 sin 23° / sin 89°

LJ = 3.51

The final answer is

LJ = 3.5

Hope this helps you.
