Answer:
mode = the most
mean =average of the numbers: a calculated "central" value of a set of numbers. ... add up all the numbers, • then divide by how many numbers there are.
median=The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
<h3>
Mark</h3>
Now we arrange all Mark's test scores first (arrange in a sequence), so it will become :
71, 74, 76, 82, 83, 94, 94
mode = 94
mean = (71 +74+76+82+83+94+94) over 7
= 574 over 7
= 82
median = 82
<h3>
Irina</h3>
Now we arrange all Irina's test scores first (arrange in a sequence too) , so it will become :
79, 79, 82, 83, 89, 95, 95
mode (there are 2 modes in Irina test) which is 79 and 95 because both of them appears twice.
mean = (79+79+82+83+89+95+95) over 7
= 602 over 7
= 86
median = 83

Answer:
m<V = 11.2 degrees
Step-by-step explanation:
In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet.
From the triangle;
UV = hypotenuse = 6.2feet
WU = opposite = 1.2feet
Required
m<V
Using the SOH CAH TOA identity
sin m<V = opp/hyp
sin m<V = WU/UV
sin m<V = 1.2/6.2
sin m<V = 0.1936
m<V = arcsin(0.1936)
m<V = 11.16
m<V = 11.2 degrees ((to the nearest tenth of a degree)
