Answer:
-3.248
Step-by-step explanation:
hope this helps (*^▽^*)
The original median is the number in the middle of 60, 70, 80, 80, 100, so the median is 80.
the new median is the number in the middle of 0, 60,70,80,80,100, the median is between 70 and 80, so it is 75
the original mean is (60+70+80+80+100)/5=78
the new mean is (0+60+70+80+80+100)/6=65
so the mean decreases more than the median. C is the answer. <span />
Answer:
D. 2040
Step-by-step explanation:
population increases by about 1 million every 10 years
in 2010, it's about 8
11 - 8 = 3
2010 + 30 = 2040
Answer:
4x^2-x-4
Step-by-step explanation:
f(x) = 4x^2-3 and g(x) = x+1,
(f - g)(x)= 4x^2-3 -( x+1)
Distribute the minus sign
=4x^2-3 - x-1
Combine like terms
=4x^2-x-4
To solve this problem, we have to manually
solve for the value of x for each choices or equations. The correct equation
will give a value of -1 since the linear equations intersects at point (-1,
-4).
<span>1st: 7x + 3 = x + 3</span>
7x – x = 3 – 3
6x = 0
<span>x = 0 (FALSE)</span>
<span>2nd: 7x − 3 = x – 3</span>
7x – x = 3 – 3
6x = 0
<span>x = 0 (FALSE)</span>
<span>3rd: 7x + 3 = x − 3</span>
7x – x = - 3 – 3
6x = -6
<span>x = -1 (TRUE)</span>
<span>4th: 7x − 3 = x + 3</span>
7x – x = 3 + 3
6x = 6
<span>x = 1 (FALSE)</span>
Therefore the answer is:
<span>7x + 3 = x − 3</span>
