<span>The list of
scores will be: 30 60 63 65 65 67. To get the median, you have to
arrange the scores from lowest to highest. The middle number is the median. In
this, case there are two numbers in the middle so you have to add the two and
then divide by two.</span>
<span>Therefore, 63 +
65 = 128 / 2 = 64.</span>
Answer:
A
Step-by-step explanation:
on the left of the equation, (6^4)^-5 = 6^-20
the right side you add the exponents so it would be (-7-3) =-10
so it would be 6^-10, which is greater than 6^-20
Answer:
2 =x
Step-by-step explanation:
f(x) = 9 - 4x
Let f(x) = 1
1 = 9 -4x
Subtract 9 from each side
1-9 = 9-4x-9
-8 = -4x
Divide by -4
-8/-4 = -4x/-4
2 =x
Answer:
No, he is not correct.
Step-by-step explanation:
For a linear equation, the equation is y=mx+b. The "b" is the initial value or the y intercept. He's missing that part. For example, y=2x. If you plug in 2, you won't get 8. The correct equation is y=2x+4. If you plug in 2, it'll give you the correct y value, 8.
Answer:
(x+1)(x+20)
Step-by-step explanation:
1) find two factors of 20 that sum up to 21.
2) 1 and 20 are two facts of 20 that sum up to 21.
