parallel lines have the same slope

y = 4x-5 the slope is 4

slope intercept form

y= mx+b

the slope is 4 and the y intercept is 3

y = 4x +3

The slope intercept form is:

y = mx + b

"m" being the slope, "b" being the y-intercept (the y value when x = 0)

For lines to be parallel, the slope has to be the same.

The slope of the given equation is 4, so your parallel line's slope is also 4.

y = 4x + b

The y-intercept is at (0,3), so your y-intercept (y value when x = 0) is 3

y = 4x + 3

4 - The area of a rectangle is 256.5m. If the length is 18m what is the perimeter of the rectangle? -

attashe74 [19]

The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter

ACT scores have a mean of 20.8 and 9 percent of the scores are above 28. The scores have a distribution that is approximately no

dimaraw [331]

Answer: 5.37

Step-by-step explanation:

Let x = ACT scores.

Given: ACT scores have a mean of 20.8 and 9 percent of the scores are above 28. The scores have a distribution that is approximately normal.

i.e. P(X>28)=0.09 (i)

Now,

$P(X>28)=P(\dfrac{X-\mu}{\sigma}>\dfrac{28-20.8}{\sigma})\\\\= P(z>\dfrac{7.2}{\sigma})\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]$ (ii)
