Angle 1 is 60 because angle 2 and 3 add up to 90. 2 is vertical to 30 degrees. Vertical angles are congruent(equal). 90-30=60

Answer:

Step-by-step explanation:

Complementary angles are 2 angles when added together = equal 90 * degrees.

The verticle angles theorem states angles opposite each other are the same degree*.

30* degrees is opposite angle 2 .

So angle 2 = 30* too

angle 2 and 3 together +equal 90* degree.

90 - 30 (angle 2) = 60*

Angle 3 is 60*

Add and simplify the result, if possible. x/18 + 3/18

Slav-nsk [51]

$\frac{x}{18}$ and $\frac{3}{18}$ both have a common denominator, so you can combine them into a single fraction:

$\frac{x}{18}+\frac{3}{18}=\frac{x+3}{18}$

You cannot simplify this fraction further:

Answer:

$\boxed{\frac{x+3}{18}}$

A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form?

Alisiya [41]

Answer:

$y = \frac{1}{4} x$

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula $m= \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of the given points into the formula and solve:

$m = \frac{(2)-(1)}{(8)-(4)} \\m = \frac{2-1}{8-4}\\m = \frac{1}{4}$

Thus, the slope is $\frac{1}{4}$ .

2) Now, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for $m$ , $x_1$ , and $y_1$ .

Since $m$ represents the slope, substitute $\frac{1}{4}$ for it. Since $x_1$ and $y_1$ represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.

$y-(1) = \frac{1}{4} (x-4)\\y-1 = \frac{1}{4} x-1\\y = \frac{1}{4} x+0\\y=\frac{1}{4}x$

Find the probability of having 2,3, or 4 successes in five trials of a binomial experiment in which the probability of success i

Georgia [21]

Answer:

65.3%

Step-by-step explanation:

Binomial distribution PMF below (along with a description)

the probabilty of getting 2, 3, or 4 successes in 5 trials is just

p(2)+p(3)+p(4)

p(2)= 5C2*.4²*(1-.4)³ = .3456

p(3)= 5C3*.4³*(1-.4)²= .2304

p(4)= 5C4*.4⁴*(1-.4)=.0768

.3456+.2304+.0768= .6528
