Answer:

Step-by-step explanation:

y=mx+b, equation for slope-intercept line

we can work out the equation based on given two points (1,1) and (7,4)

m=(y2-y1)/(x2-x1)= (4-1)/(7-1)= 3/6= 1/2

y=1/2x+b

For (1,1)

1= 1/2+b ⇒ b= 1/2

For (7,4)

4=7*1/2+b ⇒ b= 1/2

So we get

y= 1/2x+1/2

The answer is 1 for question mark

Say that you own property with a market price of $74,000. The state tax assessors have given it an assessed value of 48% of that

BigorU [14]

Answer:

Step-by-step explanation:

74,000 x .48 = 35520. 35520 is the amount of property you have to pay for.

35520 x 0.031 = 1,101.12. 1.101.12 is the amount you owe in property tax.

First we will go to the section that lists that students that like hotdogs. 76 students out of 150 like hotdogs. Out of those 76 students, which of them like burgers?
32 students like hotdogs and burgers. 32/76 is equal to .421..., which when multiplied by 100 is equal to approximately 42.1%. We found the conditional frequency, or the column frequency. The correct answer is C.
