Answer:
the average distance from the mean is 84.8
Step-by-step explanation:
The computation of the average distance from the mean is shown below;
= Total sum ÷ number of observations
= (80 + 76 + 88 + 96+ 75 + 83 + 68 + 94 + 99 + 89) ÷ (10)
= 848 ÷ 10
= 84.8
Hence, the average distance from the mean is 84.8
The probability of drawing an ace and rolling a "2" is = 0.077 × 0.167
you just multiply and get the answer.
Answer:
First, we need to know when the function is increasing, and when is decreasing.
When a function is increasing, it's because to higher <em>x-values </em>belong higher <em>y-values. </em>On the other hand, a function is decreasing when to higher <em>x-values </em>belong lower <em>y-values. </em>The effect in the graph will be a upwards direction of the function when is increasing, and a downwards direction when is decreasing.
So, according to the given graph, we see that between 0 and 4 is increasing, the higher x-values are, higher y-values are. Between 4 and 6 is decreasing, is downwards. Between 6 and 8 is increasing. Between 8 and 10 is decreasing. In finally, between 10 and 14 is neither decreasing or increasing, it remains horizontal.
All these interpretations we can expressed using math language, specifically inequalities:
- 0 < x < 4: increasing.
- 4 < x < 6: decreasing.
- 6 < x < 8: increasing.
- 8 < x < 10: decreasing.
- 10 < x < 14: neither increasing or decreasing.
