Answer:
a) No, since 80 is less than 2.5 standard deviations above the mean; b) Yes, since 80 is more than 2.5 standard deviations above the mean.
Step-by-step explanation:
For part a,
The mean is 70 and the standard deviation is 5. This means that 2 standard deviations above the mean is 70+5+5 = 80.
This means that 80 is not an outlier, as it is not more than 2.5 standard deviations above the mean.
For part b,
The mean is 70 and the standard deviation is 3. This means that 2 standard deviations above the mean is 70+3+3 = 76; 3 standard deviations above the mean is 70+3+3+3 = 79. 80 is more than this, so yes, it is an outlier.
Answer:
A and C are similar
Step-by-step explanation:
The sum of a triangles angles = 180
If you calculate the remaining angles, you will see that both A and C have the same angles and therefore are similar.
Circumference = PI * diameter
diameter = circumference / PI
diameter = 25,000 / PI
diameter =

Answer:
( 300; 353) is on the line y=1.2x−7
Step-by-step explanation:
y=1.2x−7
Substitute the point into the equation and see if it is true
353=1.2(300)−7
353 =360-7
353 = 353
This point is on the line
Answer:
Step-by-step explanation:
Since tan is equal to the opposite over adjacent
Tan(angle G)= HI/IG
