The answer is 26, the average is found by adding all the numbers and dividing by how there are. you are given 2 sets (25,12) and need to find X, the average should be 21. 25+12 is 37, 37+(c) which is 26 = 63 , you then divide 63 by how many numbers you had , which is 3 and the answer is 21.
Answer:
The probabilty of selecting a red or yellow marble is 7/12
Step-by-step explanation:
To know the probability we have to divide the number of favorable events by the number of possible events
F = Favorable events: red or yellow marble
P = Possible events: red, yellow or blue
F = 4 + 3
F = 7
P = 5 + 4 +3
P = 12
7/12
The probabilty of selecting a red or yellow marble is 7/12
Well, i don't see the answer on the listed so i will simply type it. The opposite of 5 1/5 is -5 1/5.
If you are looking for the reciprocal, the answer is 5/26(i'm adding this in too since reciprocals are often confused with opposites where i live).
Question 2.
(1,0) would go (-1,0)
(3,0) would go (-3,0)
(5,3) would go (-5,3)
(1,3) would go (-1,3)
question 4. (i think)
(0,-1) would go (-1,0)
(0,-2) would go (-2,0)
(-2,-2) would go (-2,2)
(2,0) would go (0,2)
question 5.
(-1,4) would go to (1,4)
(-1,2) would go to (1,2)
(-3,2) would go to (3,2)
(-4,4) would go to (4,4)
hope this helps! good luck!
