First, we should change the first two into percentages to make ordering them easier-

Do 21/25, which equals .84 ; you then move the decimal a couple places to get 84. That’s 84%.

Next, do the same steps to find the percentage of 25 out of 27; you would get 92.6 (rounded from 92.59)

So, knowing the percentages of those two, you can now order them from greatest to least, which would be as following:

25/27, 92%, 88%, and 21/25.

Hope that helped!

Degger [83]

Answer:

a) $49.48

b) $220921.91

Step-by-step explanation:

(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48

(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91

(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be

20% of 4.95x

(20%=0.20)

0.20 × 4.95x

I need help with number 7 and 8
devlian [24]
7.

The point-slope form of the equation of a line is

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is a point on the line.

We are given two points, so we can find the slope.

slope = m = (y2 - y1)/(x2 - x1)

The slope of this line is

m = (-3 - 7)/(5 - (-15)) = -10/20 = -1/2

Since every choice has a 7 and a 15, we now use point (-15, 7) and slope -1/2.

y - y1 = m(x - x1)

y - 7 = -1/2(x - (-15))

y - 7 = -1/2(x + 15)

BigorU [14]

Answer:

0.5%

Step-by-step explanation:

The prevalence rate shows the proportion of people that have a disease in a population and to be able to calculate it, you have to divide the number of people that have a disease by the population:

Prevalence rate=(5/1,000)*100

Prevalence rate=0.005*100

Prevalence rate=0.5%

According to this, the answer is that if there are five cases of H1N1 in the community of 1,000 people, the prevalence rate is 0.5%.
