As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others

8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^
Answer:
The probability that a randomly selected x-value lies between μ − 2σ and μ is the shaded area under the normal curve shown. P(μ − 2σ ≤ x ≤ μ) = 0.135 + 0.34 = 0.475
Step-by-step explanation:
6a^3+228a^2+4a^2b+152ab-2ab-76b^2
Answer:
14
Step-by-step explanation:
If x is -18, then we can change the equation to this:
17 + -18/6
14
Answer:
0.061
Step-by-step explanation:
Number of days Protestants
0 50
1 27
2 6
3 16
The proportion of protestant remain calm for 2 days= number of protestant calm for 2 days/ Total number of protestant calm for 0-3 days
The proportion of protestant remain calm for 2 days =6/50+27+6+16=6/99=0.061 (rounded to 3 decimal places)
Thus, 6.1% of protestant remain calm for 2 days.
