Answer:

y represents the amount in the bank account after 7 months.

Step-by-step explanation:

Let karma gets x money on his birthday.

He has 60 in his account initially

He deposits teh same money for the seven months

So, the money he has after the seven months is 7 x + 60  

According to the question,

y =7 x + 60

It shows that the amount after seven months is y.

Subtract.(8j³ + 9j² + 6j + 8) - (j² + 8)
german

As we did in the previous problem, we need to remove the parenthesis using distributive property so as to be able to combine like terms.

The first paranthesis is positive, so nothing changes as we remove it:

8 j^3 + 9 j^2 + 6 j + 8 - (j^2 + 8)

before removing the second parenthesis, we realize it is preceded by the negative sign of the indicated subtraction. Then as we remove the parenthesis, we flip the signs of all terms inside it:

8 j^3 + 9 j^2 + 6 j + 8 - j^2 - 8

now we combine like terms + 8 and - 8, rendering a zero "0". and we also combine the terms that contain j^2 : 9 j^2 - j^2 = 8 j^2.

Therefore, our final expression becomes:

8 j^3 + 8 j^2 + 6 j

Find the probability of each event. Answer IN FRACTION form.
IgorLugansk [536]

Answer:

= 8/6435

Step-by-step explanation:

Number of black balls = 8

Number of Brown balls = 5

Total number of balls = 8+5 = 13

Pr (8 balls picked at random are black ) =

Number of black balls / Total number of balls.

1st Pr ( 8 balls picked are black) = 8/13

Pr (2nd random pick) = 7/12

Pr (3rd random pick) = 6/ 11

Pr (4th random pick) = 5/10

Pr (5th random pick) = 4/9

Pr (6th random pick) = 3/7

Pr (7th random pick) = 2/6

Pr (8th random pick) = 1/5

Pr (8 balls picked at random are black ) = 8/13 * 7/12 * 6/11 * 5/10 * 4/9 * 3/7 * 2/6 * 1/5

= 8/13 * 7/12 * 6/11 * 1/2 * 4/9 * 3/7 * 1/3 * 1/5

= 8/6435

But pls note, I solved it such that there wasn't a replacement after each pick.

Math is fun

What is the result when the number 10 is increased by 3%?
Monica [59]
So if we are increasing a number, we are increasing its percentage value. The normal percentage value for an item is 100% or 1. We can take 3% and turn it into a decimal.
3% is the same as 0.03 as a decimal. The next step is to add 0.03+1 .00 to get 1.03. We have to always add the 1.00 whenever we are increasing the value. I’ll give you a reason why, let’s say you want to buy a skateboard and there are no sales so that you can get it for cheaper. The price will always be 1.00% no matter what.
So lastly we have to multiply 1.03 by 10

Which will give us 10.30
