Answer:
c + (a + 1.70) = 6.70
Step-by-step explanation:
you start the equation by Subtracting how much more alan has to the total
(this will only be set as an equation do not actually solve it)
then add 1.70 to a
"
6.70 - 1.70 = a + c
(1.70 + a)
c + (a + 1.70) = 6.70 "
Answer:
5/4
Step-by-step explanation:
(2/3)/(8/15)
= (2/3)(15/8)
= (2*15)/(3*8)
= 30/24
= 5/4
Answer:
0.21
Step-by-step explanation:
Given that Jane is a better tennis player than Jack is. If the probability that Jane will beat Jack in any given game is 0.7,
Probability for Jane beating Jack is 0.7 and hence
Probability for Jack beating Jane is 0.3
We find that each game is independent of the other
If two games are played
Probability that they will each win one game if they play two games
= Prob that Jack wins one game * Prob that Jane wins one game
= 0.7*0.3
= 0.21
(Since if A and B are independent events P(AB) = P(A) *P(B)
Answer:
first one
Step-by-step explanation:
yes, the interval does increase at -2. however, you can see it decreases again but starts rising up again at the interval 1.
Answer:
Robyn model makes more sense and Marks is nonsense.
Step-by-step explanation:
In this question ,calculations not required .All we have to do is consider each model logically .
Marks
Marks model shows 20 rather than 2 which means 200 is 10 times as much as 20. It does not make any sense.
Robyn
Robyn model shows 2 which means 200 is 100 times as much as 2 and this is not only correct but also makes sense because 100 *2=200
