Lisa saw a scale drawing of a picture in a museum (figure A). She drew a picture that
was proportional to the painting (figure B). She used the scale 1 centimeter : 2 feet. If
Lisa's picture is 4 centimeters long, what is the length in feet of the actual painting?
1 cm:
ft

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

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.
