Answer:
Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.
Step-by-step explanation:
There are 36 possible ways of throwing two dices. The following lists are shown in ordered pair:
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
a) a pair of 3's
The probability is 1/36 because there is only one pair which is (3,3).
b) any pair
The probability is 6/36 or 1/6 because the number of pairs are (1,1) (2,2) (3,3) (4,4) (5,5) and (6,6).
c) at least one 4
The probability is 10/36 or 5/18 because there would be (4,1) (4,2) (4,3) (4,5) (4,6) (1,4) (2,4) (3,4) (5,4) (6,4) for any combination.
d) a total of 9
The probability is 4/26 or 2/13 because (4,5) (5,4) (3,6) (6,3) are the totals of 9.
5) a total greater than 8
The probability is 10/36 or 5/18. Just find the ordered pair having a sum greater than 8.
Hope this helps.
Ok sooo if you get the exponents all together and then divide then you should get your answer but since you’re on here and you need it then I’ll give it to you : f(x)=4 ; sine the past (x)2years there has been f(x) 4 times as much as lions.
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8 or 8.5
