Question 7 (1 point) On a certain day, the national average for the cost of a gallon of gasoline is $2.74. An official at a gasoline company selects an SRS of 25 gas
stations and finds an average cost of $2.71 per gallon. Which of the following statements is true?
$2.74 is a statistic and $2.71 is a parameter.
Oь $2.74 is a parameter and $2.71 is a statistic.
Od $2.74 and $2.71 are both parameters.
Od $2.74 and $2.71 are both statistics.
a

i believe the answer is letter c) 8

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.
