How much money does the average professional football fan spend on food at a single football game? That question was posed to 60 randomly selected football fans.
The sampled results show that the sample mean was $70.00 and prior sampling
indicated that the population standard deviation was $17.50.
Use this information to create a 95 percent confidence interval for the population mean.

based on context clues you gave i'm assuming the answer would be c.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

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.

pi x^2

step-by-step explanation:

pi times x squared
