The history club surveyed 75 students about the number of history courses in which they were enrolled and the length of time it took them to complete an exam. Classify the random variables from the survey.
Number of history courses, continuous; length of time to complete exam, continuous
O Number of history courses, continuous; length of time
complete exam, discrete
Number of history courses, discrete; length of time to complete exam, continuous
Number of history courses, discrete; length
f time to complete exam, discrete
O Unable to determine from information given

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

wow ok so the answer is 1k or just k

because of combining like terms xd
