You flip three coins. What is the probability that you get three tails, given that you get at least two tails?

1 answer:

6 0

It’s still 50/50. Flipping coins is purely chance. There isn’t an actual pattern, our brain just create one to make sense of things!

WZ and XR are diameters of circle C. The diagram is not drawn to scale. What is the measure of ZWX?

Inessa05 [86]

Answer:

Measure of arc ZWX is <u>230°.</u>

Step-by-step explanation:

Given:

arc WX = 50°

Now

The diameter divide a circle into two equal parts

$arc\ ZWX=arc\ ZRW+arc\ WX$

Since WZ is diameter of the circle.

$arc\ ZRW=180\°$

substituting in above equation we get

$arc\ ZWX=180\°+50\°=230\°$

Hence Measure of arc ZWX is <u>230°.</u>

Quadrilateral DEFG - quadrilateral KLMN. Find the given side length.

Delvig [45]

Answer:

Step-by-step explanation:

By the diagram FG = MN.

3y + 3 = 5y - 25 Add 25 to both sides

3y + 3 + 25 = 5y Subtract 3y from both sides

28 = 5y - 3y Combine

28 = 2y Divide by 2

28/2 = 2y/2

y = 15

15 is not your answer. It is just the value of y.

3y + 3 = 3*15 + 3 = 45 + 3 = 48
