Answer:
y=3/4x-4.5
Step-by-step explanation:
know that -4.5 is the intercept
and you can calculate the slope by seeing the rise/run between the two marked points
P(two boys and one girl)
P(at least two girls)
I don't care if you cab only answer one, I would very much appreciate it if you still answered that one instead of nothing.
Answer:
1)
2)
3)
Step-by-step explanation:
Given : Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%.
To Find : The probability of each event.
1) P(at least one boy and one girl)
2) P(two boys and one girl)
3) P(at least two girls)
Solution :
Let's represent a boy with B and a girl with G
Mr. and Mrs. Romero are expecting triplets.
The possibility of having triplet is
BBB, BBG, BGB, BGG, GBB, GBG, GGB, GGG
Total outcome = 8
1) P(at least one boy and one girl)
Favorable outcome = BBG, BGB, BGG, GBB, GBG, GGB=6
2) P(at least one boy and one girl)
Favorable outcome = BBG, BGB, GBB=3
3) P(at least two girls)
Favorable outcome = BGG, GBG, GGB, GGG=4
Let's represent a boy with B and a girl with G
For example BBB is three boys and BGB is two boys and one girl.
These are all the possibilities
1) BBB
2) BBG
3) BGB
4) BGG
5) GBB
6) GBG
7) GGB
8) GGG
There is in total 8 different possibilities.
Now let's analyze the conditions
p (at least one boy and one girl)
That excludes only BBB and GGG so they are 6 possibilities out of 8
p = 6/8 = 3/4
p (two boys and one girl).
Those are 3 out of 8
p = 3/8
p (at least two girls)
Those are 3 (two girls) + 1(three girls) = 4
P = 4/8 = 1/2
Please, let me know if this was satisfactory for you.

Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Step-by-step explanation:
Step 1: Simplify the equation
7.22−4.9(5.1+3.1)
=51.84−4.9(5.1+3.1)
=51.84−(4.9)(8.2)
Step 2: Solve and subtract the numbers
=51.84−40.18
=11.66
Explanation in words:
- To solve this equation, the first step is to simplify the equation and at the end, the answer will result as = 51.84-(4.9)(8.2).
- To solve this equation, the second step is to solve that equation and break it down so we will have to subtract and at the end, the answer for this whole equation will result as = 11.66.
Answer:
= 11.66
Hope this helps.
