To find the mean, add all of the values and then divide by how many numbers
to get the median, you have to write out every number, how many ever times it appears and cross them out from the side to get to the middle number. Essentially the median is the middle number. if there are 2 middle numbers, add together and divide by 2
<span>the proccess of choosing is independent so probability of choosing from machin1 is:300/1000 =0.3
choosing from machin2 is:707/1010=0.7
the total result is 0.3*0.7=0.21 ;</span>
195- (9x25)-30. there ya go!
B is the answer.............
Answer:
54
Step-by-step explanation:
3x -(7-x) = 29 remove the parens
3x - 7 + x = 29 simplify
4x -7 = 29 add 7 to both sides of the equation
4x = 36 divide by
x = 9
then 6x = 6 * 9 = 54
