The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

The answer is C) 15

What is 5 subtracted by 6 exponent 2 divided by 4 subtracted by 3? Show how u got the answer plz I know it’s negative 7 but i do

11111nata11111 [884]

Answer: The answer is not -7 it is in fact -31.

Step-by-step explanation:

5 - ( 6^2 ) / 4 - 3

6^2 = 36

5 - ( 6^2 ) = -31

4 - 3 = 1

5 - 36 / 1 = -31 / 1 = -31

So anything divided by 1 is = to itself.

Step-by-step explanation:

there is no mode because there is no 2 or more numbers that are the same

the median is 12 because if you put the number in order: 5,8,9,12,18,22,25 then the middle number is 12

n many population growth problems, there is an upper limit beyond which the population cannot grow. Many scientists agree that t

givi [52]

Answer:

$\frac{dP}{dt} = rP(1 - \frac{P}{K}) = 0.017P(1 - \frac{P}{16})$

Step-by-step explanation:

The logistic function of population growth, that is, the solution of the differential equation is as follows:

$P(t) = \frac{KP_{0}e^{rt}}{K + P_{0}(e^{rt} - 1)}$

We use this equation to find the value of r.

In this problem, we have that:

$K = 16, P_{0} = 2, P(50) = 4$

So we find the value of r.

$P(t) = \frac{KP_{0}e^{rt}}{K + P_{0}(e^{rt} - 1)}$

$4 = \frac{16*2e^{50r}}{16 + 2*(e^{50r} - 1)}$

$4 = \frac{32e^{50r}}{14 + 2e^{50r}}$

$56 + 8e^{50r} = 32e^{50r}}$

$24e^{50r} = 56$

$e^{50r} = 2.33$

Applying ln to both sides of the equality

$50r = 0.8459$

$r = 0.017$

The differential equation is

$\frac{dP}{dt} = rP(1 - \frac{P}{K}) = 0.017P(1 - \frac{P}{16})$

If the standard deviation is 7.3kg, what is the variance?

sasho [114]

Answer:

The variance is 53.29 kg²

Step-by-step explanation:

The standard deviation is the square root of the variance.

$S(X) = \sqrt{V(X)}$

In which problem, we have that:

$S(X) = 7.3$

$\sqrt{V(X)} = 7.3$

$\sqrt{V(X)}^{2} = (7.3)^{2}$

$V(X) = 53.29$

The variance is 53.29 kg²
