Answer:
the average probability of all possible outcomes of a future event occurring, weighted by each possible outcome individually
Step-by-step explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In Statistics, an expected value can be defined as the average probability of all possible outcomes of a future event occurring in an experiment, weighted by each possible outcome individually. Thus, an expected value in theory refers to the outcome an individual expect to obtain from an experiment in the long-run.
Mathematically, an expected value can be calculated by summing the products of each distinct outcome and their probability respectively.
Answer:
1) 8.5
2) 60
3) 69.3
4) 6.8
5) 3.6
6) 10.5
Step-by-step explanation:
Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 <em>or </em>276)
Answer:
100 times
Step-by-step explanation:
25000/250= 100

Answer: 7</h2>
<h3>
Step-by-step explanation:</h3>
32256 ÷ 2688 - (4 +1)
4 +1 = 5
32256 ÷ 2688 = 12
<h2>FINALLY, 12 - 5 = 7</h2>
*Hope this Helps :) Mark me brainliest :)
No solution:
3/2x + 2.3 - 1/2x = 4.3 + x
5r + 2 = 6r + 3 - r
one solution:
2x + 2/3 = 2x + 4/5 - 4x
3.2p - 2.5 + 2.1p = 5p - 7/2
infinitely many:
17/4 + 4.2y - 9/4 = 2.2y + 6 + 2y - 4
-2z + 2 + 4z = 16/5 + 2x - 6/5
