Answer:

ok so the probility of gettting one white fish is

13/23

and if we take out one white fish the problity is

12/22

so we just multiply

12/22*13/23=0.30830039525

so the problity is 0.30 if you choose two fish you will get white for both

True or False: If your friend wants to take 6 hours for the 300 mile drive and you want to take 6 hours for the 240 mile drive,
Mila [183]

Answer: I'm pretty sure this is false.

Step-by-step explanation:

If you are driving the same amount of time as your friend, then you travel the same distance, unless you are going different speeds. The person that travels the most amount of distance would be going faster, in this case your friend.

Please don't quote me on this, I only THINK this is right, not 100%

Find the slope of the line that passes through (10, 8) and (1, 9)?
sdas [7]

Answer:

The answer is

<h2>-  \frac{1}{9}</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(10, 8) and (1, 9)

The slope is

m =  \frac{9 - 8}{1 - 10}  =  \frac{1}{ - 9}  \\  =  -  \frac{1}{9}

We have the final answer as

-  \frac{1}{9}  \\

Hope this helps you

Two groups of friends go to a movie. Each ticket costs the same amount. One group spends ​$57. The other group spends ​$95. List
kenny6666 [7]

Answer:

1) All possible number tickets for group that spends $57: A, B, C, D

2) All possible number tickets for group that spends $95: B, C, E, F

3) Each ticket will cost at most $19

Step-by-step explanation:

We are told that one group spends $57 dollars while the other group spends $95.

Now,we want to find all possible whole number ticket prices for each group and at most how much each ticket​ costs.

To do this, let's first find the factors of both amounts which will give us all possible whole number ticket prices for each group.

57: 1, 3, 19, 57

95: 1, 5, 19, 95

Since each ticket costs same amount, to find out at most how much each ticket costs, we will select the highest common factor of both groups which is 19.

Thus,each ticket will cost at most $19

PLZZZZ HELLPP  50 POINTS TO WHO CAN ANSWER CORRECTLY
finlep [7]
For this case we are going to assume that Nina wrote:
 3/4 (1440) + 295.25 + (-33.50).
 The expression is correct since we have:
 ticket sales were three-fourths as much as yesterday. That means
 3/4 (1440)
 food sales were down by $ 33.50, that means:
 295.25 + (-33.50)
 Therefore, today's sales were:
 3/4 (1440) + 295.25 + (-33.50).
 answer
 Nina's expression is correct
