The function y=f(x is graphed below. What is the average rate of change of the function f(x)on the interval 0≤x≤5?

Answer:

A. c = 60 / p

Step-by-step explanation:

If p=2, the equation would read... c = 60 / 2, which mean c = 30. If c = 12, the equation would read... 12 = 60 / p, and p = 5, and so on, 20 = 60 / 3, and 15 = 60 / 4.

Answer:

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

They randomly survey 391 drivers and find that 319 claim to always buckle up.

This means that [tex]n = 391, \pi = \frac{319}{391} = 0.8159[/tex]

85% confidence level

So [tex]\alpha = 0.15[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.15}{2} = 0.925[/tex], so [tex]Z = 1.44[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 - 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.7877[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 + 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.8441[/tex]

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).

D. 2x+71=180

Step-by-step explanation:

Six angles are represented, three are marked. The six angles add up to 360 (360 degrees in a circle). We know that the sum of all the marked angles equals 180, because each marked angle has an equal, unmarked, vertically opposite angle, and half of 360 is 180. Therefore we can write:

76+(x-5)+x=180

2x+71=180

Answer:

force (f)= 14000N

acceleration (a)=5m/s²

mass (m)=?

we have,

f=ma

14000=m×5

14000/5=m

2800=m

therefore Mass is 2800kg

The sampling technique is used to make observation about entire population. The sampling may be misleading if the graphs are not properly drawn. This could mislead the reader and the sampling technique will not be scientific.

Sampling may be unscientific when the graphs are drawn in a way to mislead the reader.

Sampling is a simple way of carrying out scientific studies. In a sampling technique, a small fraction of the whole is selected for study in such a manner that represents the whole.

Answer:

Area = 20.28 cm^2

Perimeter = 16.28 cm

Step-by-step explanation:

The figure is composed of a half circle and a rectangle,

The circle has a diameter of 7 - 2 - 1 = 4cm and the rectangle is of side 2 cm and 7 cm.

Therefore the area is :

Area = A rectangle + Acircle/2 = 2*7 + pi*r^2/2 = 20.28 cm^2

The perimeter is :

Perimiter = 1 + 2 + 7 + Pcircle/2 = 1 + 2 + 7 + 2*pi*r/2 = 16.28 cm

Answer:

y = 0.44 x - 0.1

Step-by-step explanation:

Using the points (2.5, 1) and (27.5, 12) (first and last points of the plot - please see attached image), we obtain the following slope:

slope = (y2 - y1) / (x2 - x1)

slope = (12 - 1 ) / (27.5 - 2.5) = 0.44

Now we use this slope to complete the equation of the line through those points:

y = 0.44 x + b

1 = 0.44 (2.5) + b

1 = 1.1 = b

b = 1 - 1.1

b = - 0.1

Therefore, the equation of the line becomes:

y = 0.44 x - 0.1

Answer:

y = 0.44x + 0

Step-by-step explanation:

I am going to use the first and lowest and highest points on the graph to make an equation representing the approximate slope of this graph.

(2.5,1) and (27.5,12)

To find slope I am going to calculate change in y over change in x.

12 - 1 over 27.5 - 2.5 = 11/25 = 0.44

So far we have y = 0.44x + 0

To find "b" (the y-intercept) we are going to plug zero in for x, because the defintion of y-intercept is "the value of y when x = 0"

We get that the y intercept equals 0.

y = 0.44x + 0 or just y = 0.44x

Answer:

It is a linear equation

Answer:

Option B, The mean will increase, but the median will remain the same.

Step-by-step explanation:

Given

Mean value is  [tex]31.52[/tex] dollars

Median Value is [tex]32[/tex] dollar.

Mean is the average of all the units in a given set of data. Change in any of the number will change the mean.

Here the mean is 31.25

Total money would be [tex]31.25 * 25 = 781.25\\[/tex]

A number is changed from 2 to 20 , i.e addition of 18 dollars

the new mean would be 781.25 + 18/25 = 31.97

However, the median value is the value of the unit at the center of the arrangement. Hence, it will not change.

Option B is correct

Answer:

(12x + 18)/(x+9)

Step-by-step explanation:

We have: (x + 11x + 18)/(x+9). First simplify this equation by adding like terms.

(12x + 18)/(x+9), which is your answer. This is the final answer because we can't simplify this expression anymore.

Answer:

12.5x+10

Step-by-step explanation:

I'm assuming that you want to simplify this, because there is no equal sign.

If you want to simplify, first combine like terms.

First solve the first half of the equation: 20x-7.5x=12.5x

Now solve the second half of the equation: 12-2=10, so we have 12.5x+10.

That's your answer: 12.5x+10

Answer:

x = 0.8

Step-by-step explanation:

Your equation is 5(4x - 1.5x) + 12 - 2. Simply, you have to solve for x.

First, you have to do distributive property. 5 x 4 and -1.5 (1.5 is negative as I plus-minus.) This will now lead you to have the equation 20x + -7.5x + 12 - 2.

Next, you subtract 12 - 2. Then add 20x + -7.5x. Your equation should be 12.5x = 10.

Since you want x by itself, you will divide all by 12.5 in which 10 divided by 12.5 is 0.8. So your final answer is

x = 0.8
