We know that
[scale factor ]=[real]/[drawing]
[real]=[drawing]*[scale factor ]

step 1
find the real values

if the base of Riley's drawing is 10 centimeters
 [real]=[drawing]*[scale factor ]--------> 10*3-------> 30 cm
the base of the triangular clock face is 30 cm

the  height of Riley's drawing is 15 centimeters 
[real]=[drawing]*[scale factor ]--------> 15*3-------> 45 cm
the  height of the triangular clock face is 30 cm

the  area of the triangular clock face is-----> 45*30/2-------> 675 cm²

the answer is the option C. 675 square centimeters

1. A sample consists of 75 TV sets purchased several years ago. The replacement times of those TV sets have a mean of 8.2 years.
Greeley [361]

Answer:

8.2+/-0.25

= ( 7.95, 8.45) years

the 95% confidence interval (a,b) = (7.95, 8.45) years

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 8.2 years

Standard deviation r = 1.1 years

Number of samples n = 75

Confidence interval = 95%

z value(at 95% confidence) = 1.96

Substituting the values we have;

8.2+/-1.96(1.1/√75)

8.2+/-1.96(0.127017059221)

8.2+/-0.248953436074

8.2+/-0.25

= ( 7.95, 8.45)

Therefore the 95% confidence interval (a,b) = (7.95, 8.45) years
