According to the chart, from 1976-1986, unintentional drug overdose deaths per 100,000 population stayed relatively stable. the numbers for each year are, roughly, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2. what is the mean of these statistics?

1.09

Step-by-step explanation:

Given that according to a chart from  1976-1986, unintentional drug overdose deaths per 100,000 population stayed relatively stable.

The numbers for each year are, roughly, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2.

We know that mean =

Thus the means of these statistics= 1.09

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

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.
