3x+2=20 PLEASE ANSWER AND EXPLAIN PLEASE I DON’T UNDERSTAND MATH

cluponka [151]

Answer: 6

Step-by-step explanation: okay. Here we go. This will be long.

You have to use the inverse operation. That means use the opposite operation. For example, the opposite operation of addition is subtraction. So let’s ignore the 3x for now. That means the equation is +2=20. The inverse operation of addition is subtraction. So we subtract 2 from 20. That equals 18. Then we subtract 2 from 2. That equals 0. Now our equation is =18. Now remember 3x? You bring that back in. So our equation is 3x=18. See what I did? I simplified the equation. 3x means “3 times x” because x is a variable. And the opposite of times (multiplication) is division. So you divide 3 from 18. That equals 6. And we divide 3 from 3x. That equals 1x. Ax is basically the same thing as x. So now what doe we have left? X= 6. Your answer is 6.

Determine the point estimate of the population mean for the confidence interval of (15, 32). Enter up to 1 decimal place. Point

netineya [11]

Answer:

The point estimate of the population mean for the confidence interval of (15,32) is 23.5

Step-by-step explanation:

We are given the following information in the question:

Confidence interval for population mean is (15, 32).

We have to find the point estimate for population mean.

Formula:

$\mu = \displaystyle\frac{\mu_1+\mu_2}{2} = \frac{15+32}{2} = 23.5$

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5

A source of laser light sends rays AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B an

Nataly [62]

Answer:

The distance between the walls is 70 m.

Step-by-step explanation:

Given: A source of laser light is at point A on the ground between two parallel walls BE and CD . The walls are perpendicular to the ground that is

BE ⊥ ED and CD ⊥ ED

AB is a ray of light which strikes the wall on the left at point B which is 30 meters above the ground. that is BE = 30 m

AC is a ray of light which strikes the wall on the right at point C. The length of AC = 80 meters.

The ray AB makes an angle of 45 degrees with the ground that is m∠BAE = 45°

The ray AC makes an angle of 60 degrees with the ground that is m∠CAD = 60°

As shown is figure attached below.

WE have to find the distance between the walls that is Length of ED

Length of ED = EA + AD

Consider the Δ AEB,

Using trigonometric ratio,

$\tan\theta=\frac{perpendicular}{base}$

Here $\theta=45^{\circ}$ , perpendicular = 30 m and base we can find.

thus,

$\tan 45^{\circ}=\frac{30}{EA}$

We know $\tan 45^{\circ}=1$

thus, EA = 30 m

Consider the Δ AEB,

Using trigonometric ratio,

$\cos\theta=\frac{base}{hypotenuse}$

Here $\theta=60^{\circ}$ , hypotenuse = 80 m and base we can find.

thus, $\cos 60^{\circ}=\frac{base}{80}$

We know, $\cos 60^{\circ}=\frac{1}{2}$

thus, Base = 40 m

AD = 40 m

Thus, the distance between the walls that is the length of ED = 30 + 40 = 70 m
