Answer:
what are the answer choices
Step-by-step explanation:
Answer:
40 degrees
Step-by-step explanation:
There are always 180 degrees in a triangle, so add up the two known angles
114+26=140
then subtract this amount from 180 to get the last remaining angle
180-140=40 degrees
Answer:
0.125
Step-by-step explanation:
It could be a lot of things, but if you mean the decimal form then it would be 0.125. Just divide 1 by 8.
Answer:
103.68
Step-by-step explanation:
Answer:
0.0323 = 3.23%. Is unusual
Step-by-step explanation:
Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability
z = (x - mean)/standard deviation
z = (5-8.54)/1.91
z = -1.85
Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from
p = 1- 0.9677
p = 0.0323
An event with a probability less than 5% is considered unusual.
