At a ski area in northern Vermont, the daytime high temperature in January is normally distributed with a mean of 22°F and a standard deviation 10°F. What is the probability that a randomly selected day in January will have a daytime high of A. greater than 45°F?
B. between 30°F and 40°F?
C. lower than 15°F?

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

pls ask

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
