Answer:
B
Step-by-step explanation:
Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).
You can also do this
\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\
(y2-y1)/(x2-x1) (the numbers are subscripts)

The required value of mean and variance is 203 and 3942 respectively.
Hence option B is correct.
The sample includes the following claims: 192, 113, 200, 287, and 225.
<h3>What is Statistic?</h3>
The statistic is the study of mathematics which deal with relations between comprehensive data.
Mean(x) = 192+113+200+287+225/5
x = 203
variance =
=summation of squared value/n^2−1
=15769/25−1
=15769/24
=3942
Thus, the required value of mean and variance is 203 and 3942 respectively.

Answer:
a
Step-by-step explanation:
Probabilty usally ends in a %
if probability of a coin landing on heads is 50% and if and
a doesnt describe probability which is why a should be the anwser
though d says 120% the person running the race has full convidence describing themselves that they will win
a doesnt describe any probability it just says 1!! but thats why a is the anwser because its inncorrect!
