Can someone help me with number 135?
Nat2105 [25]

so from accidental deaths we have

30 from falls

47 from fires

200 from drowning

1950 car accidents


so the total of those is 30+47+200+1950, or 2227.


the ones that weren't car accidents will be 2227 - 1950, or 277.


if we take 2227 to be the 100%, how much is 277 off of it in percentage?


\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 2227&100\\ 277&x \end{array}\implies \cfrac{2227}{277}=\cfrac{100}{x}\implies x=\cfrac{277\cdot 100}{2227} \\\\\\ x\approx 12.4382577~\hspace{7em}\stackrel{rounded~up}{x=12}

Which table represents a linear function that has a slope of 5 and a y-intercept of 20?
Novay_Z [31]

Answer:

The table in the attached figure

Step-by-step explanation:

we know that

The equation of a line into slope-intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

m=5

b=20

the equation is equal to

y=5x+20

Construct the table

a) For x=-4

Find the value of y

y=5(-4)+20=0

b) For x=0

Find the value of y

y=5(0)+20=20

c) For x=4

Find the value of y

y=5(4)+20=40

d) For x=8

Find the value of y

y=5(8)+20=60

The table in the attached figure
