Step-by-step explanation:
x * 5 - 17 = 103
x * 5 = 120
x = 24
Answer:
5.93 * 10^7
7 represents the amount of times you moved the decimal
Work shown above! Box a is 240 lbs Box b is 120 and Box c is 150 lbs hope this helps c:
first qn
4/36=1/9
total no. of ways to roll a dice=36
no. of ways to produce 7=3
(1+6=7, 2+5=7, 3+4=7)
no. of ways to produce 11=1
(5+6=11)
there are 4 ways in total. 4/36 simplify it to be 1/9
second qn im not sure but i think its
1/9 x 50 = 50/9 = 5 x (5/9)
round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
