A researcher is interested in estimating that average commute time of people in a city. assume that the commute time follows a normal distribution with a standard deviation of 9.4 minuets. the researcher takes a sample of 10 people and obtains the average communte time of 26.3 minuets. estimate 99% confindence interval for the population mean, that is the error term

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
