Hoping to get information that would allow them to negotiate new rates with their​ advertisers, Natural Health magazine phoned a random sample of 600 subscribers.​ 64% of those polled said they use nutritional supplements. Which is​ true? I. The population of interest is the people who read this magazine. II.​ '64%' is not a​ statistic; it's the parameter of interest. III. This sampling design should provide the company with a reasonably accurate estimate of the percentage of all subscribers who use supplements.

step-by-step explanation:

because that's the answer

one peck is 9.309 quarts

9.309x 2

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b
