Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean
Step-by-step explanation:
In the figure attached, the distribution of data is shown.
From the picture we can see that:
- The data has a standard deviation of 0.15 (= 0.5 - 0.35 = 0.65 - 0.5)
- The mean of the data is 0.5
- A value of 0.7 is more than 1 standard deviation of the mean.
- A value of 0.9 is more than 2 standard deviations from the mean (0.8 is 2 standard deviations from the mean)
Answer:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
we know angle RLP= 100⁰
also
angle RLP+ angle RLB=180⁰(Linear pair)
=>100⁰+angleRLB= 180⁰
=> angle RLB=80⁰
since BR and LR are equal, angle RBL and angle RLB are equal
therefore angle RBL is also equal to 80⁰
using angle sum property of triangles we know that the sum of all angles in a triangle is equal to 180⁰
=>angle BRL+angle RBL+angle RLB= 180⁰
=> angle BRL+80⁰+80⁰=180⁰
=>angle BRL = 180⁰-160⁰
=>angle BRL= 20⁰
