Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 7, 3, 2, 1, 13, 8, 1, 5, 14, 11,
zysi [14]
Answer:
Mean = 7.3, median = 7, mode = 1.
Step-by-step explanation:
First arrange the data in order:
1 1 2 3 5 7 8 11 13 14 15
There are a total of 11 values.
Median = middle value = 7.
Mode = the most common number = 1.
Mean = sum / 11
= 80 / 11
= 7.3.

The angle for this triangle is more than 89°.
An acute triangle is a triangle that is smaller than an 90° triangle.
Answer:
-203
Step-by-step explanation:
We know that by formula
p^3 – q^3 = (p – q) (p^2 + pq + q^2 ) -------(1)
(p-q)^2 = p^2 -2pq +q^2 --------(2)
Solving eq(1)
(-7)^2 = p^2 -2(-10) +q^2
49 = 10 +p^2 + q^2
p^2 + q^2 = 39--------(3)
Given:
p-q = -7
pq = -10
Put all given values and eq(3) in eq(1)
p^3 - q^3 = (-7) (39-10)
p^3 - q^3 = (-7) (29)
p^3 - q^3 = -203
