Step-by-step explanation:
a = 5
b = -3
25 - -3/ -3 - 25
= 28 / -28
= -1
Answer:
Approximately 10.2 inches
Step-by-step explanation:
The area of a square is given by the formula:

Where A is the area and s is the side length.
Since we already know that the area A is 105, substitute:

Now, take the square root of both sides:

Use a calculator:

So, the side length is approximately 10.2 inches.
Answer: y= 66
Step-by-step explanation: Well first you would do +7 on both sides and then it would be Y/6=4+7, then you would multiply 6 on both sides which then you would have y=24+42 which simplified it would be y=66
Answer:
a) There are 8 possible combinations and each probability is 1/8.
b) The probability that it is a boy given that there are two girls is 3/8
Step-by-step explanation:
a) The sample space is given by:
BBB (3 boys)
BBG (Boy, boy, girl)
BGB (Boy, girl, boy)
BGG (Boy, girl, girl)
GBB (girl, boy, boy)
GBG (girl, boy, girl)
GGB (girl, girl, boy)
GGG (3 girls)
The probability of each combination is the same:
P(BBB)=P(B∩B∩B)=
2) There are three possible combinations in which there are 2 girls and 1 boy:
BGG, GBG, GGB
So the probability is given by:
P(BGG ∪ GBG ∪ GGB)=
I think is 22
sorry if i'm wrong
