You move the decimal 3.4, 2 places to the right and get 340 then you move the decimal 4.37, 2 placeto the right and you multiply 340 and 437 and you get 14858 and you move 3 decimal place to the left because you moved 3 decimal place so you have to move it back and you get 14.858
The answer are (1, 5) and (1, 3)
Answer:
56
Step-by-step explanation:
The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)
The number of both spiners land on red is 84.
So we have:
X——>100%
84——->30%
X=8400/30
X=280
The total number of all spines A and B for onse.
The probability to both spiners land on blue is:
0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)
The number of both spiners land on blue is:
280*0,2=56
2x - 5 = 7
2x = 7 + 5
2x = 12
2x/2 = 12/2
x = 6
to check:
2x - 5 = 7
2(6) - 5 = 7
12 - 5 = 7
7 = 7
