Step-by-step explanation:

you have to add the numbers including 90 which is 210 then subtract from 180 because angles on a straight-line sum to 180 and you'll get 30 hope its correct

Answer:

x = 60

Step-by-step explanation:

We notice that the angle with 120° is adjacent and supplementary to Angle X, so they add up to 180°. We can write this algebraically as 120 + x = 180 and solve for x.

Step 1: Subtract 120 from both sides.

$120 + x - 120 = 180 - 120$
$x = 60$

Step 2: Check if solution is correct.

$120 + 60 = 180$
$180 = 180$

Therefore, x = 60.

Which calculation can be used to find the value of q in the equation q3 = 64?

alexandr402 [8]

To isolate the variable q, divide both sides by 3:
q3 ÷ 3 = 64 ÷ 3
q = 21.33 or 21 1/3

If the q is cubed(I can't really tell), however, you would use the cube root:
³√q³ = ³√64
q = 4

Find the slope of the line that contains the following points. R(-3, 5), S(3, -2) 7/6 7/6 undefined

Musya8 [376]

Answer:

-\frac{7}{6}

Step-by-step explanation:

We can use the slope formula for the segment that joins any two points $(x_1, y_1)$ and $(x_2, y_2)$ :

$slope=\frac{y_2-y_1}{x_2-x_1}$

which in our case gives:

$slope=\frac{y_2-y_1}{x_2-x_1} = \frac{-2-5}{3-(-3)}=\frac{-7}{6} =-\frac{7}{6}$

Answer:

The point estimate for this problem is 0.48.

Step-by-step explanation:

We are given that a University wanted to find out the percentage of students who felt comfortable reporting cheating by their fellow students.

A survey of 2,800 students was conducted and the students were asked if they felt comfortable reporting cheating by their fellow students. The results were 1,344 answered "Yes" and 1,456 answered "no".

Let $\hat p$ = proportion of students who felt comfortable reporting cheating by their fellow students
