8y-3=13 so what does y equal

2 answers:

8 0

Add 3 on both sides

8y - 3 + 3 = 13 + 3

8y = 13 + 3

8y = 16

Divide 8 on both sides

8y/8 = 16/8

y = 16/8

y = 2

y = 2

Answer:

Step-by-step explanation:

i used 1980 and 1985. I subtracted 42.1 by 33.4, got 8.7, divided that by 5 since theres been 5 years since, then multiplied by 6 since theres a 6 year difference from 2005 and 2011, then added them.

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is

ser-zykov [4K]

Answer:

(a) $\frac{1}{17}$ (b) $\frac{1}{16}$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.

SOLUTION:

(a)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

As sampling is done without replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{12}{51}$

$=\frac{4}{17}$

Probability that first card is club and second card is club $=P(A)\times P(B)$

$=\frac{1}{4}\times\frac{4}{17}=\frac{1}{17}$

(b)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

As sampling is done with replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

Probability that first card is club and second card is club $=P(A)\times P(B)$

$=\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}$

The sum of 8 and B is greater than 22

Alinara [238K]

Given:

The sum of 8 and B is greater than 22.

To find:

The inequality for the given statement and its solution.

Solution:

We know that, sum of two number is the addition of two numbers.

Sum of 8 and B = 8+B

It is given that, the sum of 8 and B is greater than 22.

$8+B>22$

Subtracting 8 from both sides, we get

$8+B-8>22-8$

$B>14$

Therefore, the required inequality for the given statement is $8+B>22$ and the solution is $B>14$ .

1.5 cups per day how many gallons per weeek? (1gallon =16cup)

anyanavicka [17]

So as you know, one gallon has 16 cups, and there's 7 days in a week. So, if you multiple 1.5 by 7 you would get 10.5 cups per week, then divide that by 16 and get .65625 gallons per week.
