Answer:
10 and 42
Step-by-step explanation:
The difficulty with word problems is translating them into math.
Let's do that
---------------------
The sum of a number and two times a smaller number is 62.
let's call the bigger number b, and the smaller number s
b + 2s = 62
Three times the bigger number exceeds the smaller number by 116
3b = s + 116
-----------------------
Now manipulate one of the equations to isolate the variable
3b = s + 116
Subtract 116 from both sides
3b - 116 = s
substitute for s = 3b - 116 in
b + 2s = 62
b + 2(3b - 116) = 62
Distribute
b + 6b - 232 = 62
combine like terms
7b = 294
Divide both sides by 7
b = 42
to find s plug in b = 42 into
b + 2s = 62
42 + 2s = 62
subtract 42 from both side
2s = 20
divide both sides by 2
s = 10
7.3 ------ 8.1 8.5 8.9
let us try to find the common difference here using last three terms
8.5-8.1=0.4
8.9-8.5=0.4
so it is clear that common difference is 0.4
so adding 0.4 to 7.3 will give the next term
7.3+0.4=7.7
Answer : missing number is 7.7
The probability of hitting it once is the ratio of the bullseye area to the whole target.
So 144/484=.2975
For it to happen twice in a row, would be this squared which is .088=.09 or 9%
