Answer: D. Park B showed faster growth between 2009 and 2014, at an average rate of 120 swallows per year.

Step-by-step explanation:

I did the math

The Park B showed faster growth between 2009 and 2014, at an average rate of 100 swallows per year i.e. option A.

The average rate is defined as a measure of how much the function changed per unit, on average, over that interval.

We have,

x is time, in years, since 2005,

and,

f(c) is population in hundreds.

Now,

For Park A,

at x = 4 ,

Swallows Population = 2370

and,

at x = 9,

Swallows Population = 2870

So,

Average Rate [tex]=\frac{2870 - 2370}{10} = 50[/tex]

Now,

For Park B,

at x = 4,

Swallows Population = 2200

and,

at x = 9,

Swallows Population = 2800

So,

Average Rate [tex]=\frac{2800- 2200}{10} = 60[/tex]

So,

Difference in average rate = 60 - 50 = 10

From the average rate of of both park A and Park B,

We can see that,

Park B has faster growth rate of 100 per year.

Hence, we can say that the Park B showed faster growth between 2009 and 2014, at an average rate of 100 swallows per year i.e. option A.

Answer:

1/5^3

Step-by-step explanation:

5 ^ -3 = 1 / 5^3 = 1 / 125

Difference means subtraction; in other words, the difference between data is calculated by subtracting the smaller value from the larger value.

The difference between the population living in the urban and the rural area of Mongolia are: 1195830

To continue, I will make the following observations dataset for Mongolians.

[tex]Population = 3.225\ million[/tex]

[tex]Rural = 31.46\%[/tex]

[tex]Urban = 68.54\%[/tex]

The difference (d) in the percentages is:

[tex]d = Urban - Rural[/tex]

[tex]d = 68.54\% - 31.46\%[/tex]

[tex]d = 37.08\%[/tex]

So, the actual difference (in numbers) is the product of the percentage difference by the population of Mongolia

i.e.

[tex]D = d * Population[/tex]

[tex]D = 37.08\% * 3.225\ m[/tex]

[tex]D = 1195830[/tex]

Hence, the difference between the population living in the urban and the rural area of Mongolia are: 1195830

Answer:

x = 25°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

The given triangle is a right triangle which means one of its angle has a measure of 90°

since thd other angle is given as 65 to calculate x we just add the given measures and subtract it from 180

90° + 65 + x = 180

155 + x = 180 subtract 155 from both sides

x = 25°

Answer:

Step-by-step explanation:

Angles BGC and FGE share vertex G and are composed of opposite rays. This makes them vertical angles.

Angle BGC and CGD make up a right angle, so they are complementary. That makes angle BGC equal to 90° -40° = 50°.

Vertical angles have the same measure, so ∠FGE = 50°.

Answer:

339.24

Step-by-step explanation:

To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2

The radius is half the diameter do r=3

3.14(3)^2 should give you about 28.27.

This is the area of the top and bottom of the cylinder.

Now, do 28.27x10=282.7 to find the height surface area.

282.7+28.27+28.27=Surface area.

SA= about 339.24

Answer:

The standard deviation of the comparison distribution is 0.5657.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this question:

Standard deviation of the population is 8, sample of 200. So

[tex]s = \frac{8}{\sqrt{200}} = 0.5657[/tex]

The standard deviation of the comparison distribution is 0.5657.

Answer:

(a). The length of the field is 1,300 - 2·x

(b) The area of the rectangular field is 1,300·x - 2·x²

(c) x leading to the maximum area is 325 meters

(d) The maximum area is 211,250 m²

Step-by-step explanation:

The given parameters are;

The length of fencing the compound owner has = 1,300 m

The shape of the field he wants to enclose = Rectangular field

The width of the field he wants to enclose = x

The fence on the side along the river = No fencing along the river

(a). Let 'l' represent the length of the field, we, have;

2·x + l = 1.300

∴ l = 1,300 - 2·x

The length of the field, l = 1,300 - 2·x

(b) The area of a rectangular field, A = Length of the field, l × Width of the field, w

Therefore;

The area of the rectangular field, A = x × (1,300 - 2·x) = 1,300·x - 2·x²

The area of the rectangular field = 1,300·x - 2·x²

(c) The coefficient of x² is negative, therefore, the graph of the area has a maximum point

The value of 'x' leading to maximum area is given by differentiating the function representing the area, equating the result to 0, and fining the value of 'x' as follows;

d(A)/dx = d(1,300·x - 2·x²)/dx = 1,300 - 4·x

d(A)/dx = 0 at the maximum point

∴ 1,300 - 4·x = 0

4·x = 1,300

x = 1,300/4 = 325

x leading to the maximum area = 325 meters

(d) The maximum area, [tex]A_{max}[/tex] is given by A = 1,300·x - 2·x², when x = 325

∴ [tex]A_{max}[/tex] = 1,300 m × 325 m - 2 × (325 m)² = 211,250 m²

The maximum area, [tex]A_{max}[/tex] = 211,250 m²

Step-by-step explanation:

My keyboard won't do pounds. I'll leave the units off and just use pure numbers.

Magazines

Number of magazines = 50

Commission                  = 10/100

Price of magazines       = 7

Books

Number of books    =      21

Cost per book          =     12

Commission             =      15/100

Solution

Income from magazines = 10/100 * 7 * 50 =                                      35

Income from books         = 15/100 * 12 * 21                                        37.80

Basic Pay                                                                                            150

10 miles in feet is 52800ft.

1 mile in feet is 5280 and when multiplying by 10, you usually just add a zero at the end of the number which makes 5280 turn into 52800!

The measure of the arc is 214 degrees

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The measure of the arc FE is 146 degrees.

Measure ED is 90 degrees.

To find the measure of the arc EDF we have to find the measure of DF.

146+90+x=360

236+x=360

Subtract 236 from both sides

x=360-236

x=124

Now let us find the arc measure EDF =Measure of ED + Measure of DF

=90+124

=214 degrees

Hence, the measure of the arc is 214 degrees
