A study has shown that the daily amount of milk produced by dairy cow is normally distributed with a mean of 6.2 gallons in a standard deviation of 0.7 gallons on a given day 95% of the cows will produce the amount of milk within which of the following ranges

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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.

table 3 represents a direct variation function. : )
