Answer:
z = 16
y = 9
Step-by-step explanation:
14.87
Step-by-step explanation:
use the Pythagorean theorem
a^2+b^2=c^2
C being the longest side of the triangle
14^2+5^2=C^2
196+25=C^2
221=C^
find the square root of 221
C=14.866
rounded to nearest tenth
C=14.87

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!
