Step-by-step explanation:
Slope, which is the same as gradient, is equal to
change in y axis ÷change in x axis
<h3>
</h3>
Our coordinates are (-12,-12) and (9,-9)
In (-12,-12),let the first -12 be <em>x1</em><em> </em>and the second one be <em>y1</em>
Same goes for the (9,-9), let 9 be <em>X2</em><em> </em>and -9l be <em>y2</em>
<em></em>
<em></em>
<em></em>
<em>=</em>0.1428571429
= 0.1429
Answer:
Step-by-step explanation:
Let X denote the amount of time spending exercise in a given week
Given that X normal (3.8, (0.8)²)
Thus we know that
i)P [ amount of time less than two hour ]
= P[x < 2]
ii)
= P[z > 2.25] ∴ symmetric
= P[0 ≤ z ≤ ∞] - P[0 ≤ z ≤ 2.25]
= 0.5 - 0.48778
= 0.0122
iii)
P[2 < x < 4]
