Hello!
First of all, we need to find the mean. To find it, we add up all of the scores and divide by the number of tests.
85+93+78+90+88+97+88=619
619/7≈88.43
Mean≈88.43
Now we need to find the median. First we order the numbers from least to greatest.
78,85,88,88,90,93,97
Now we have to find the middle number. As you can see, the number in the middle is 88.
Median: 88
Finally, we need to find the mode. This is the number that appears the most. As you can see, 88 appears twice, while all of the others appear only once. Therefore, our mode is 88.
Mode:88
I hope this helps!
Answer: -4x^3 y^10
-2x^3 • 2 = 4 (because 2•2 is 4, they don’t share the same variable so you just multiply the base)
y^9 • y^1 (9+1=10)
-4x^3 y^10
It's D, $49.00/wk for x weeks is 49x, plus $18.00 bonus is 49x+18, add the fact that Mini worked for y weeks, 49y.
Read it slowly and out loud till you get it.
The second one. The very top of the graph is at (6,3). The axis of symmetry is always the x value of the vertex, so x = 6
