Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 148148 millimeters, and a variance of 3636. If a random sample of 4040 steel bolts is selected, what is the probability that the sample mean would be less than 147.2147.2 millimeters

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

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.
