Answer:

1st one:

37 - 25 = 12

2nd one (to the right of the one on the top-left):

(19 - 10) - 7 = 2

3rd one (below the one of the top-left):

Since BD = 13 and CD = 10, BC must equal 3.

AC would equal the sum of 8 and 3.

8 + 3 = AC

11 = AC

4th one:

Not exactly sure what you want to find here, add more info.

But if you want to find the middle or mid-point:

10 + 3x + 5 = 25

15 + 3x = 25

3x = 10

Divide by 3 on both sides:

x = 3.33 or 31/3 or 10/3

5th one (bottom-left):

*First find x*

9 + x + 2x - 3 = 30

6 + 3x = 30

3x = 24

Divide both sides by 3:

x = 8

*Now that you have x, you can find the length of DE:

2(8) - 3 = DE

16 - 3 = DE

13 = DE

Two friends argue about the calculated probability of flipping a coin to show heads three times in a row. steve mentions that ea

den301095 [7]

Solution:

A coin is flipped three times,resulting three heads in a row.

Since Steve has mentioned that , each flip of a coin is unconnected to the previous flip.

Two or more events are said to be independent if occurrence of one of them is not affected by the Occurrence of other.

This is an example of independent events.

In terms of probability, P (A∩B∩C)= P(A)×P(B)×P(C)

I cant add mixed fractions with whole numbers

butalik [34]

If you add the whole number to the whole number part of the mixed number, and then add the fraction from the mixed number on to the end of that, you get a new mixed number which is your answer.
