Answers

Answer 1

Answer:

C )  For this​ problem, the mean value of 283 represents the average test score on a mathematics assessment test for​ eighth-graders.

Step-by-step explanation:

10 th  percentile of 232

10 % below 232 and 90 % above 232

25 th percentile of 255

25 % below 255 and 75 % above 255

75 th percentile of 304

75 % below 304 and 25% above 304

90 th percentile of 327

90 % below 327 and 10 % above 327 .

So counting is from below to above in ascending order .

the mean of 283 represents the average of the test score

Hence option C ) is correct .

Answer 2

The score of the mathematics test for the 8th class have a mean of 283 and the 10th percentile of 232, a 25th percentile of 255 nd so on.

As per the question the 10 th percentile of 232 , hence the 10 % below 232 and 90 % above 232 . The 25 % below 255 and 75 % above 255 , 75% below 304 and 25% above 304. The 90 % below 327 and 10 % above 327 . So  in ascending order the mean of 283 represents the average of the test score. Hence the option C is correct.

A product can be made in sizes huge, average and tiny which yield a net unit profit of $14, $10, and$5, respectively. Three centers manufacture these products. The centers respectively have a capacity ofturning out 550, 750, and 275 units of the product per day, no matter what sizes are involved. The manufacturing process necessitates cooling water and each unit of huge, average, and tiny sizesproduced require 22, 16, and 9 gallons of water, respectively. Center 1 has 11,000 gallons of coolingwater available per day, Center 2, 7000, and Center 3, 4000 gallons. The daily demand is of 710, 900,and 350 units of the huge, average, and tiny siz. By company policy, the fraction (scheduled production)(center's capacity) must be the same at all the centers. The company wishes to maximize its profits.

Solution:

The x-intercept can be found by solving for x when y=0.

  3x +5 = 0 +5

  3x = 0

  x = 0 . . . the x-intercept

Oranges cost 21 cents each.
Alex buys x oranges and Bobbie buys (x+2) oranges.
The total cost of these oranges is $4.20.

Answers

Step-by-step explanation:

x be the number of oranges

x + (x+2) = $4.20

2x + 2 = 4.20

2x = 2.20

x = 1.1

if you wanna check,

1.1 + (1.1 + 2) =$4.20

1.1 + 3.1 =$4.20

4.2 =$4.20

Alex = x = 1.1 oranges

Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges
