Answer is 18
I found it by multiplying 20 by .90
Answer:
10.5%
Step-by-step explanation:
The tangent of the angle is the ratio of rise to run.
tan(angle) = grade
tan(6°) ≈ 0.105 = 10.5%
The grade will be 10.5% for an angle of elevation of 6°.
Answer:
0.032109
Step-by-step explanation:
From the given information
the estimate of those afflicted with diabetes = 0.0826
the estimate of those that are not afflicted with diabetes = 1 - 0.0826
= 0.9174
From adult with 40
Pr (correct diagnoses) = 0.945
Pr(incorrect diagnoses) = 0.035
The objective that the probability of a randomly selected adult which is over 40 and does not have diabetes, and is diagnosed as having diabetes (false positive) is = 0.9174 × 0.035
= 0.032109
Answers are: 83 and 77
Notice how...
The jump from 98 to 97 is a decrease of 1
The jump from 97 to 95 is a decrease of 2
The jump from 95 to 92 is a decrease of 3
The jump from 92 to 88 is a decrease of 4
The pattern of decreases so far is: 1, 2, 3, 4
So the next decrease is 5
88-5 = 83
And the decrease after that is 6
83-6 = 77
