Answer:
sine 70 = opposite / hypotenuse
sine 70 = 12 / x
x = 12 / sine 70
x = 12 / 0.93969
x = 12.7701688855 cm
x = 12.8 cm (rounded to nearest tenth.
Step-by-step explanation:
Answer:(−∞,-13)
Step-by-step explanation:
solve for x the convert to interval notation
<em>x<-13 → </em>(−∞,-13)

Since it's a < and not a ≤ you use a parentheses instead of a bracket
The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.
According to my TI-83 calculator,
normalcdf(110,120, 100, 15) = 0.16, or 16%.
