Answer:
Option C) 0.2358
Step-by-step explanation:
We are given the following data set:
0.23105, 0.4725, 0.8765, 0.4865, 0.5326, 0.7976
Formula:
where are data points, is the mean and n is the number of observations.
Sum of squares of differences = 0.1122752556 + 0.008765640625 + 0.09633264063 + 0.006340140625 + 0.001123925625 + 0.05358067562 = 0.2784182787
Thus, the standard deviation for given data is
Option C) 0.2358
Answer:
s≥22
Step-by-step explanation:
49-5
2s≥44
divide both sides of the inequality by 2
so 2s≥44 then turn into s≥22
11x12-(-8)x(-1)
132+8x(-1)
132-8
124
Answer: 35
Step-by-step explanation:
Triangle BDC is an equilateral triangle
Triangle ABD is an isosceles triangle
so the length of BD is 8
because BDC is equilateral all sides are 8
then you add your numbers up
8+8+8+11
=35
Answer:
Step-by-step explanation:
1. The solid line passes trough the points (0,4) and (-2,0). The equation of this line is:
The origin doesn't belong to the shaded region, so its coordinates do not satisfy the inequality. Thus,
2. The dotted line passes trough the points (0,2) and (2,0). The equation of this line is:
The origin belongs to the shaded region, so its coordinates satisfy the inequality. Thus,
Hence, the system of two inequalities is
