Answer:

Step-by-step explanation:

red balls=3

blue balls=4

total balls=3+4=7

probability of selecting 3 red balls=3/7 ×2/6×1/5=1/35

selecting 1 red ball=3/7

after selecting there are two red balls and total balls are 6

so now P=2/6

and so on .

Solve the system algebraically<br> x+3y=11<br> 4x-4y=7
ololo11 [35]

Answer:

x = 65/16,   y = 37/16

Step-by-step explanation:

solve the system algebraically

x+3y=11

4x-4y=7

Try substitution.

let  x =  11 - 3y

Plug in.

4(11 - 3y) - 4y = 7

44 - 12y - 4y = 7

44 - 16y = 7

37 = 16y

y = 37/16

x = 11 - 3*y

x = 11 - 3*(37/16)

x = 11 -  111/16

x = 65/16

I didn’t pay attention in class help
Alona [7]

Answer:

The 1/4th power means the 4th root of a number.

Therefore for the first question, the answer should be 4th root of 1296 -4th root of 625. or \sqrt[4]{1296}

4

1296

-\sqrt[4]{625}

4

625

:D

For the second question just calculate? what to the 4th power is 1296 and what to the 4th power is 625?

They should respectively be 6 and 5. So the final answers we get is 6-5=1

If you have any questions about this just ask me in the comment and I will get to it as soon as I could.

hopecthis helps
