The equation of the line of best fit relating age (in years) and the median height (in cm) of boys is given. y
=
6.5
x
+
75.5
y=6.5x+75.5
Which statement below best interprets the slope in the context of the problem?

The slope is 6.5, this means that the median height for boys at age 0 is 6.5 cm.

The slope is 75.5, this means that the median height for boys at age 0 is about 75.5 cm.

The slope is 75.5, this means that each boys grow approximately 75.5 cm.

The slope is 6.5, this means that each year boys grow approximately 6.5 cm.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
