Find the perimeter of this figure to the nearest hundredth

Answer:

Mean = 9

Step-by-step explanation:

The mean is the average of a data set.  Given the values, 2, 9, 10, 12, 12:

Add all the numbers in the data set, and divide its sum by the number of items in the set:

Mean = [tex]\frac{2+9+10+12+12}{5}[/tex] =  [tex]\frac{45}{5}[/tex] = 9

Therefore, the mean of the given data set is 9.

Answer:

x + y + z - 3

Step-by-step explanation:

Basically, putting a negative sign before parentheses signifies that you want to flip the sign of everything within the parentheses. This can also be explained by the negative sign representing -1.

Knowing this, we can just multiply everything within by -1.

-y -> y

-z -> z

3 -> -3

We now have y + z - 3, just put this into the original expression and we have our final answer of:

x + y + z - 3

According to the question given,

[tex]\sf\longmapsto \: emigrants=-5000[/tex]

[tex]\sf\longmapsto \: Immigrants = 100000[/tex]

[tex]\sf\longmapsto \: Death -350000[/tex]

[tex] \sf \longmapsto \: Birth=600000[/tex]

Now let's solve out and get the result!

The change of population:

[tex] \sf \longmapsto600000-350000 + 100000 - 5000=350000[/tex]

The total population at the end of the year:

[tex]\sf\longmapsto \:2000000 + 350000 [/tex]

[tex]\sf\dashrightarrow2350000[/tex]

At the end of the year, the population will be 20,345,000.

The rate of change in population is 1.75%.

Rate is a measurement to determine the change in one quantity with respect to another quantity.

The given information are,

Total population of the country initially = 20,000,000

Total number of births during the year = 600,000

Total number of deaths during the year = 350,000

Number of immigrants = 100,000

And number of emigrants = 5,000

The population at the end of the year

= 20,000,000 + 600,000 - 350,000 + 100,000 - 5,000

= 20,345,000

At the end of the year the population will be 20,345,000.

The increase in population  = 20,345,000 - 20,000,000

                                              = 345,000

the rate of increasing = 345000/20000000)x100  = 1.75%

The rate of change per year is 1.75%.

Answer:50000000000000000000000000000000000000000000000000000

Answer:

4

Step-by-step explanation:

( 5x - 6 ) and ( 3x + 2 ) are alternate interior angles.

Alternate interior angles are equal,

So,

5x - 6 = 3x + 2

5x - 3x = 2 + 6

2x = 8

x = 8 / 2

x = 4

The total pies Anna can bake is 22.

The total pies Anna can bake would be determined by the amount of cups of sugar she has. Anna has already baked 17 pies. From the question, one cup of sugar can bake two pies. This means that the number of additional cups she has would be multiplied by two in order to determine the total number of pies she can bake.

Pies Anna can bake = additional cups of sugar x 2

11 x 2 = 22 pies

Step-by-step explanation:

mark me brainlist amswer.

Answer:

112°

Step-by-step explanation:

1. The angle with 112 degrees and angle x are corresponding angles, which mean they have the same relative position. Corresponding angles are congruent.

2. Given the information above, m∠x = 112°.

In this problem, first we find the sample mean and the standard deviation, and then, we use the normal distribution. Then, we get that:

a) The mean is of 199.69 and the standard deviation is of 25.02.

b) 0.2148 = 21.48% probability that, on a randomly selected day, the early morning trading volume will be less than 180 million shares.

c) 0.1131 = 11.31% probability that, on a randomly selected day, the early morning trading volume will exceed 230 million shares.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Item a:

The mean is the sum of all observations divided by the number of observations, thus:

[tex]\mu = \frac{214 + 163 + 265 + 194 + 180 + 202 + 198 + 212 + 201 + 174 + 171 + 211 + 211}{13} = 199.69[/tex]

The standard deviation is given by the square root of the sum of the difference squared between each observation and the mean, divided by the number of values. Thus:

[tex]\sigma = \sqrt{\frac{(214-199.69)^2 + (163-199.69)^2 + (265-199.69)^2 + (194-199.69)^2 + ... + (211-199.69)^2}{13}} = 25.02[/tex]

The mean is of 199.69 and the standard deviation is of 25.02.

Item b:

This probability is the p-value of Z when X = 180, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{180 - 199.69}{25.02}[/tex]

[tex]Z = -0.79[/tex]

[tex]Z = -0.79[/tex] has a p-value of 0.2148.

0.2148 = 21.48% probability that, on a randomly selected day, the early morning trading volume will be less than 180 million shares.

Item c:

This probability is 1 subtracted by the p-value of Z when X = 230, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{230 - 199.69}{25.02}[/tex]

[tex]Z = 1.21[/tex]

[tex]Z = 1.21[/tex] has a p-value of 0.8869.

1 - 0.8869 = 0.1131

0.1131 = 11.31% probability that, on a randomly selected day, the early morning trading volume will exceed 230 million shares.

Answer:

The center of the circle is at: C=(−2,3).

The radius of the circle is r=5.

Step-by-step explanation:

A circle with center at (h,k) and a radius of r has equation (x−h)2+(y−k)2=r2.

In this example our circle equation can be written as:

(x−(−2))2+(y−3)2=(5)2

So, we have: h=−2 , k=3 and r=5.
