The probability of winning a game is 10%. how many times should you expect to win if you play 80 times? 5 times 10 times 8 times

Darya [45]

8 times.

If you play 80 times and have a 10% chance of winning, divide 80 by 10 you get 8, therefore you win 8 times.

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your way home, you travel at an average r

kenny6666 [7]

Answer:

14 miles

Explanation:

The relation that will be used to solve this problem is:

$Distance = Velocity*Time$

which can be rewritten as:

$Time = \frac{Distance}{Velocity}$

Assume that:

Distance from your house to your friend's house is d

Time taken from your house to your friend's house is t₁

Time taken from your friends house to your house is t₂

1- From your house to your friend's house:

Average rate = 35 miles/hour

Therefore:

$t_{1} = \frac{d}{35}$

2- From your friend's house to your house:

Average rate = 40 miles per hour

Therefore:

$t_{2} = \frac{d}{40}$

3- Round trip:

We know that the round trip took 45 minutes which is equivalent to 0.75 hours

This means that:

t₁ + t₂ = 0.75 hours

$\frac{d}{35}+\frac{d}{40}=0.75\\ \\\frac{40d + 35d}{1400}=0.75\\ \\\frac{75d}{1400}=0.75\\ \\ 1050 = 75d\\ d=14 miles$

Hope this helps :)

Help please 2x-3y=12 find y if x is 0

mafiozo [28]

For this, you simply plug in 0 for "x" and solve:

2(0) - 3y = 12 multiply 2x0 to get 0
0 - 3y = 12 0 - 3y is -3y
-3y = 12 Isolate your variable by diving both sides by -3
y = -4 you're left with y = -4

Answer: if x is 0, y is -4
