We are to find the predicted and relative frequency of the defective calculators.
a) The company claimed that there is 1% probability of defective calculators out of 1000.
So predicted frequency = 1% of 1000
= 0.01 x 1000
= 10
b) 15 defective calculators were found in 1000 calculators.
Relative Frequency = Observed Frequency / Total Number
= 15/1000 x 100%
= 1.5%
Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
Yes the ratio of a right angle is 1:4
First you need to work out what (8.12×105=?) Then (5.27×105=?) And add them together so (8.12×105)+(5.27×105)=the answer to your question
