The solution to the compound inequality are____​

Answer:

[tex]m = 0.2[/tex]

Step-by-step explanation:

To solve this equation we're basically trying to isolate m on one side.

The equation is [tex]m^2=0.04[/tex].

If we want to make it [tex]m=x[/tex], we have to find the square root of both sides, as the square root of something squared is just that something.

[tex]\sqrt{m^2} = \sqrt{0.04}[/tex]

To find the square root of 0.04, we need to think "what number multiplied by itself get us 0.04?"

This number is 0.2.

So:

[tex]m = 0.2[/tex]

Step-by-step explanation:

The cube of something to the 1/3 power is the original something. The cube of a cube root of something is the original something. Since the cube of a cube root is the same as the cube of a 1/3 power, the 1/3 power is equivalent to the cube root.

Answer:

C. [tex] z = 82 [/tex]

Step-by-step explanation:

To find z, find x first:

[tex] 105 = \frac{1}{2}(x + 120) [/tex] (angle of intersecting chord theorem)

Solve for x

[tex] 105*2 = \frac{1}{2}(x + 120)*2 [/tex]

[tex] 210 = x + 120 [/tex]

[tex] 210 - 120 = x + 120 - 120 [/tex]

[tex] 90 = x [/tex]

[tex] x = 90 [/tex]

Find z:

Full circle = 360°

Therefore,

[tex] x + z + 68 + 120 = 360 [/tex]

[tex] 90 + z + 68 + 120 = 360 [/tex]

[tex] z + 278 = 360 [/tex]

[tex] z + 278 - 278 = 360 - 278 [/tex]

[tex] z = 82 [/tex]

Answer:

75°

Step-by-step explanation:

In a parallelogram, any two adjacent angles are supplementary. In other words, they total 180.

Angle D and Angle E are adjacent. Thus, they are supplementary. In other words:

[tex]\angle D +\angle E =180[/tex]

Substitute them for the equations:

[tex]7x+21+15+5x=180[/tex]

Combine like terms and add on the left:

[tex]12x+36=180[/tex]

Subtract 36 from both sides:

[tex]12x=144[/tex]

Divide both sides by 12:

[tex]x=12[/tex]

Thus, the value of x is 12.

Note that Angle D and Angle C are also adjacent. Thus, their angles also equal 180.

So:

[tex]\angle D+\angle C =180[/tex]

Substitute the equation for D:

[tex]7x+21+\angle C=180[/tex]

Plug in 12 for x:

[tex]7(12)+21+\angle C =180[/tex]

Simplify:

[tex]84+21+\angle C =180\\105+\angle C =180[/tex]

Subtract 105 from both sides:

[tex]\angle C =75\textdegree[/tex]

Thus, Angle C is 75 degrees.

Answer:

A -3 − 4i C 13 + i

Step-by-step explanation:

We add the real part and the imaginary part separately.

Adding A and C will give us 10 - 3i:

-3 - 4i + 13 + i

= -3 + 13 - 4i + i

Answer:

the answer is c: 44

hope it helps

:)

The value of m in the equation one-half m minus three-fourths n equals 16, when n equals 8 is 44.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The equation form;

1/2m - 3/ 4n = 16

Substituting the value of n in the equation, we have;

½m - ¾n = 16

½m - (¾×8) = 16

½m - 6 = 16

½m = 16 + 6

½m = 22

m = 44

Hence, The value of m in the equation one-half m minus three-fourths n equals 16, when n equals 8 is 44.

Distance covered by Sean

= 540-x-y inches

Distance covered by Hannah =x

Step-by-step explanation:

Sean and Hannah are 540 inches apart and begin walking towards each other. Sean walks 2.6 times as fast as Hannah

Distance covered by Hannah =x

Distance between sean and Hannah= y

Distance covered by Sean= 540-x-y

Sean speed= (540-x-y)/t

Hannah speed= x/t

(540-x-y)/t /(x/t )= 2.6

(540-x-y)/x = 2.6

(540-x-y)= 2.6x

Answer:

r = -7

Step-by-step explanation:

Solve for r:

8 r + 9 = -4 (3 - r) - 7

-4 (3 - r) = 4 r - 12:

8 r + 9 = 4 r - 12 - 7

Grouping like terms, 4 r - 12 - 7 = 4 r + (-7 - 12):

8 r + 9 = 4 r + (-7 - 12)

-7 - 12 = -19:

8 r + 9 = 4 r + -19

Subtract 4 r from both sides:

(8 r - 4 r) + 9 = (4 r - 4 r) - 19

8 r - 4 r = 4 r:

4 r + 9 = (4 r - 4 r) - 19

4 r - 4 r = 0:

4 r + 9 = -19

Subtract 9 from both sides:

4 r + (9 - 9) = -9 - 19

9 - 9 = 0:

4 r = -9 - 19

-9 - 19 = -28:

4 r = -28

Divide both sides of 4 r = -28 by 4:

(4 r)/4 = (-28)/4

4/4 = 1:

r = (-28)/4

The gcd of -28 and 4 is 4, so (-28)/4 = (4 (-7))/(4×1) = 4/4×-7 = -7:

Answer:

x  = - 2 is confirmed to be the real solution of the equation.

Step-by-step explanation:

We are tasked with the following activities

Conjecture: How many solutions do [tex]x^3 - 5x^2 + 28 = 0[/tex]  have?

Find the real solution(s) of the equation.

Then use polynomial long division to find the other solution(s).

To start with the how many solutions that  [tex]x^3 - 5x^2 + 28 = 0[/tex]  have

suppose that -2 happens to be a root of the equation, we can easily replace x = - 2 in the given equation. Then , we will have :

[tex](-2)^3 - 5(-2)^2 + 28 = 0[/tex]

[tex]-8 - 5\times 4 + 28 = 0[/tex]

-8 - 20  + 28 = 0

-28 - 28 = 0

0 = 0

The equation resulted to 0 = 0 when x = -2 , as such -2 happens to be one root of the equation

So , as x = - 2

x + 2 = 0  

x  = - 2 is confirmed to be the real solution of the equation.

A picture showing the polynomial long division method used for solving the polynomial equation and other solution(s) can be found in the attached file below.

Step-by-step explanation:

Answer:

The point estimate = 0.507

Margin error of  a given confidence interval = 0.032

Step-by-step explanation:

The point estimate is calculated by using the sample statistics of a population.

Thus; point estimate can be expressed with the formula:

[tex]\overline x = \dfrac{\sum \limits ^n _{i=1} \ x _i}{n}[/tex]

Given that : 0.475 < p < 0.539

[tex]\overline x = \dfrac{0.475+0.539}{2}[/tex]

[tex]\overline x = \dfrac{1.014}{2}[/tex]

[tex]\overline x = 0.507[/tex]

The point estimate = 0.507

The margin of error  which shows  the percentage of points that the derived results would differ from that of the given population value can be calculated with the formula:

Margin error of  a given confidence interval = [tex]\mathtt{\dfrac{upper \ confidence \ limit - lower \ confidence \ limit }{2}}[/tex]

Margin error of  a given confidence interval =  [tex]\dfrac{0.539-0.475}{2}[/tex]

Margin error of  a given confidence interval = [tex]\dfrac{0.064}{2}[/tex]

Margin error of  a given confidence interval = [tex]0.032[/tex]

Complete Question

A biologist reports a confidence interval of (3.5,4.9) when estimating the mean height (in centimeters) of a sample of seedlings. What is the estimated margin of error and the sample mean?

Answer:

The  margin of error is  [tex]E = 0.7[/tex]

The  sample mean is  [tex]\= x = 4.2[/tex]

Step-by-step explanation:

from the question we are told that

   The  upper limit is  [tex]k = 4.9[/tex]

    The  lower limit is  [tex]r = 3.5[/tex]

Generally the margin of error is mathematically represented as

      [tex]E = \frac{k - r}{ 2}[/tex]

      [tex]E = \frac{ 4.9 - 3.5 }{2}[/tex]

     [tex]E = 0.7[/tex]

Generally the sample mean is mathematically evaluated as

        [tex]\= x = k - E[/tex]

=>    [tex]\= x = 4.9 - 0.7[/tex]

=>    [tex]\= x = 4.2[/tex]
