An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation: 29.8 49.3 30.6 28.1 29.0 26.5 33.2 29.3 23.8 31.6

Compute the following. (Round your answers to four decimal places.)

a. The sample range 25,5 mL/kg/min
b. The sample variance s2 from the definition (i. e., by first computing deviations, then squaring them, etc.) mL2/kg2/min2
c. The sample standard deviation mL/kg/min
d. s2 using the shortcut method mL2/kg2/min2

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!
