Hello!
First we have to find the measurement of angle SRU.
180 - 84 = 96
96/2 = 48
Angle SRU = 48 + 90 = 138
All angles in a triangle add the 180
180 - 138 - 30 = 12
The answer is B)12°
Hope this helps!
Step 1
Given; If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F and a standard deviation of 0.93°F.
Using the empirical rule, what is the approximate percentage of healthy adults with body temperatures between 96.34°F and 100.06°F?
Step 2
(3^0-(3^2)^3)/9^3
3^0=1
3^2=(3*3)=9->9^3=(9*9*9)=729
1-729=-728
9^3=(9*9*9)=729
-728/729
Answer:
59
Step-by-step explanation:
20+12=22
9+16=25
22+25=47
47+12=59
