Hi if you can help me that’d be great! Just show me the work/steps you took to answering the question and your explanation!

Answer:

a) The mean is 0.05 and the standard deviation is 0.0218.

b)  v. The sampling distribution of p is not approximately normal because n(1 - p) is less than 10.

Step-by-step explanation:

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex].

If [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], the sampling distribution of the sample proportion p will be approximately normal.

Consider the population consisting of all adult Americans age 65 and older who prefer to watch the news, and suppose that for this population the actual proportion who prefer to watch online is 0.05.

This means that [tex]p = 0.05[/tex]

A random sample of n = 100 people

So [tex]n = 100[/tex]

(a) What are the mean and standard deviation of the sampling distribution of p?

Mean [tex]\mu = p = 0.05[/tex]

Standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.05*0.95}{100}} = 0.0218[/tex]

The mean is 0.05 and the standard deviation is 0.0218.

(b) Is the sampling distribution of p approximately normal for random samples of size n 100? Explain.

[tex]np = 100*0.95 = 95 > 10[/tex]

[tex]n(1-p) = 100*0.05 = 5 < 10[/tex]

As n(1-p) < 10, it is not approximately normal, option v.

Answer:

The Least Common Multiple (LCM) is:   19 x 43 = 817

Step-by-step explanation:

Answer:

y=45x+115

Step-by-step explanation:

We can find the slope of a line tangent to a curve at a point by evaluating the derivative of the function at that point.

We are given the function

f ( x ) = 4 x 3 + 12 x 2 + 9 x + 7

= f ( x ) = 4 x 3 + 12 x 2 + 9 x 1 + 7 x 0

Using the power rule, let's now compute the derivative of  f( x )

f ' ( x ) = ( 3 ⋅ 4 x 2 ) + ( 2 ⋅ 12 x ) + ( 1 ⋅ 9 x 0 ) + 0 ⋅ 7 x − 1

f ' ( x ) = 12 x 2 + 24 x + 9

We can now find the slope of  f ( x )  at  x = − 3  by substituting this value into f ' ( x )

f ' ( − 3 ) = 12 ( − 3 ) 2 + 24 ( − 3 ) + 9

f'(-3)=12(9)+24(-3)+9

f'(-3)=108-72+9

f'(-3)=45(slope of the tangent line at  x = − 3

Now that we have a slope for the tangent line, we need to identify a point on the line.

We know the tangent line touches the function  f ( x )  at the point  x = − 3 , so let's find the value of  f ( x )  at this point:

f(-3)=4(-3)3+12(-3)2+9(-3)+7

f(-3)=4(-27)+12(9)+9(-3)+7

f(-3)=108+108-27+7

f'(-3)=-20

So we know the tangent line goes through the point

(-3,-20)

Finally, we can use the point-slope formula for a line to find the equation of the tangent line.

y=mx+b

To find the value of  b , substitute the values we have calculated for the point and slope of the tangent line:

(-20)=(45)(-3)+b

-20=-135+b

b=115

So our final answer for the equation of the tangent line is:

y=45x+115

10% of 50 is 5. So that means 5 questions were answered correctly.

Each row cannot have the same number of trees.

In mathematics, the term "divisibility" describes a number's ability to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.

As per the given data:

Number of apple trees = 987

Number of rows = 9

To find whether each row has the same number of trees:

If 987 is divisible by 9 then, the same number of trees can be there else not.

= (987/9) = (329/3) = 109.667

Not divisible, so same number of trees cannot be there.

Hence, each row cannot have the same number of trees.

y = StartFraction 7 Over 9 EndFractionx + StartFraction 17 Over 9 EndFraction

Step-by-step explanation:

Find two points and draw a line through them

y = 1/2(2) + 5

y = 1 + 5, 6

One point is (2,6)

y = 1/2(0) + 5

y = 5

Second point is (0,5)

I inserted a graph on desmos for example

Step-by-step explanation:

Rewrite in slope-intercept form.

[tex]y = \frac{1}{2} x + 5[/tex]

Use the slope-intercept form to find the slope and y-intercept.

Slope is : 1/2

y-intercept: (0,5)

Any line can be graphed using two points. Select two x values, and plug them into the equation in order to find the corresponding y values.

Answer:

a) 94

b) 56

Step-by-step explanation:

a)

Supplement means it adds up to 180 so:

180 - 86 = 94

b)

Complement means it adds up to 90 so:

90 - 34 = 56

Answer:

7.5 more push-ups

Step-by-step explanation:

From the dot plot attached :

Last month mean :

Σfx/Σf

Σfx = [(10*2)+(15*2)+(25*3)+(35*1)] = 160

Σf = (2 + 2 + 3 + 1) = 8

Mean = 160 / 8 = 20

This month mean :

Σfx/Σf

Σfx = [(10*1)+(15*1)+(25*1)+(30*3)+(40*2)] = 220

Σf = (1 + 1 + 1 + 3 + 2) = 8

Mean = 220/8

Mean = 27.5

Difference in mean :

This month mean - Last month mean

27.5 - 20

= 7.5

(0,0) (1,45) (2,90) (3, 135) (4, 180) etc, etc

Answer:

(4, 180)

Step-by-step explanation:

Choices: (3,5), (4,60), (4,180), (5,9)

y = 45x

The value of y is 45 times the value of x.

The only point in which that is true is (4, 180) since 45 * 4 = 180.

Answer: (4, 180)

Answer:

The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Centered at the the origin

Center (0,0), which means that [tex]x_0 = 0, y_0 = 0[/tex]

radius of 1/2

This means that [tex]r = \frac{1}{2}[/tex]

Equation:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - 0)^2 + (y - 0)^2 = (\frac{1}{2})^2[/tex]

[tex]x^2 + y^2 = \frac{1}{4}[/tex]

The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]
