Answer:
A. x=4 y=11
Step-by-step explanation:
y=x+7
y=-2(y-7)+19
y=-2y+14+19
y=-2y+33
y+2y=33
y(1+2)=33
y=33/3
y=11
x=4
Answer:
A random sample is a sample drawn in such a way that is random and does not favor another party. For example if a bakery owner is conducting a survey on what his customers would like to add to the menu, it would not be a random sample if he only asked customers 50 years old and older. Instead he would have to ask all ages for it to be accurate.
We will find the numerator step by step for each expression:
For 10/15 = x / 60
x = (10/15) * (60)
x = 40
For x / 108 = 4/9
x = (4/9) * (108)
x = 48
For 7/11 = x / 121
x = (7/11) * (121)
x = 77
For x / 144 = 2/6
x = (2/6) * (144)
x = 48
The answer is -42.
Hope it helps.
