Answer:

40°

Step-by-step explanation:

As sum of angles of the triangle is 180°

therefore the third angle will be 180 -( 75 + 65)=40°

x=40°= vertically opposite angle

Answer:

x = 40°

Step-by-step explanation:

a + 65 + 75 = 180 {Angle sum property}

a + 140 = 180

a = 180 - 140

a = 40

x = a {Vertically opposite angles}

x = 40°

At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.

My name is Ann [436]

x=8

Step-by-step explanation:

move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8

For the equation 8x + 2y = 16 What is the slope? What is the y-intercept (write as an ordered pair)? What is the x-intercept (wr

LiRa [457]

Answer:

y= -4x+16, (4,0), (0, 8)

Step-by-step explanation:

Let us rewrite the equation in slope intercept form, y=mx+b, where m is the slope:

2y= -8x+16

y= -4x+16

Therefore, -4 is the slope.

The x intercept can be found if we substitute 0 into the y:

0= -4x+16

4x=16

x=4

(4,0)

The y intercept can be found if we substitute 0 into the x:

2y= -8*0 +16

2y=0+16

2y=16

y=8

(0,8)

I hope this helps! :)
