Answer:
A) it increases the mean value of the prizes.
Step-by-step explanation:
The median is resistant to large outliers, so it does not change if there is an especially large or small value. So, we can eliminate choices C and D.
I am actually not sure whether the data in the table count $100 as a large prize or a small one, but I am <em>assuming</em> it is a large prize. So, an extremely large prize would increase the mean value of the prizes.
Hope this helps!
8g + 10 = 35 + 3g
8g + 10 - 3g = 35
5g + 10 = 35
5g + 10 - 10 = 35 - 10
5g = 25
5g/5 = 25/5
g = 5
Answer:
A
Step-by-step explanation:
the last number is the y intercept so the intercept in the line is -3.5 so I just matched them up.
set up an equation to solve for x
2-x ≥ 0
subtract 2 from each side:
-x≥ -2
multiply both sides by -1 ( to make x positive) and reverse the sign
x≤2
Answer:
129 physics textbooks, 183 biology textbooks
Step-by-step explanation:
Let x be the number of biology textbooks and x-54 the numbers of physics textbooks.
So:
x+(x-54)=312
2x-54=312
2x=366
x=183
So 129 physics textbooks and 183 biology textbooks were sold.
