Answer:

a) R = 3.6

b) A = 2

Step-by-step explanation:

To find the value, start by modeling the inverse proportionality by using the base equations with the original givens.

y = k/x

12 = k/1.5

18 = k

Now we use that to model the equation

R = 18/A

And we can now use that to solve parts a) and b)

R = 18/A

R = 18/5

R = 3.6

R = 18/A

9 = 18/A

2 = A

The distribution of scores on a test is mound-shaped and symmetric with a mean score of 78. If 68% of the scores fall between

Salsk061 [2.6K]

Answer:

The standard deviation for the distribution of scores is 6.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 78

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Empirical Formula:

Almost all the data lies within three standard deviation from mean for a normal data.
for this rule almost all the data lies within on tandard deviation from the mean.

68% of the scores fall between 72 and 84, thus, we can write:

$\mu + \sigma = 84\\\mu - \sigma = 72\\78 - \sigma = 72\\\Rightarrow \sigma = 6$

Thus, the standard deviation for the distribution of scores is 6.

Becky adds 3/4 gallon of gasoline into her snow thrower's empty fuel tank. She uses 1/4 gallon for the snowstorm on Friday, and

Kaylis [27]

Amount of fuel in the tank before the story begins . . . . . zero.

Total amount poured in . . . . . 3/4 gallon.

Total amount burned:
   on Friday . . . . . 1/4 gallon
   on Sunday . . . . 1/4 gallon
   Total used . . 1/2 gallon .

Amount remaining in the tank on Monday:

   (3/4 gallon in) - (1/2 gallon burned) = 1/4 gallon left.
      ==> NOT empty

The tank would have been empty on Monday IF Becky
had poured in only 1/2 gallon, instead of 3/4 of a gallon
before the first flakes began to fly.

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is

KiRa [710]

You can solve the system of equations.

Multiply the first equation by -3 and add to the second equation.

            -3x - 3y = -72
            3x + 5y = 100
(add)     --------------------------
                            2y = 28

y = 14

x + y = 24
x + 14 = 24
x = 10

Answer:
There are 10 3-points questions and 14 5-point questions.

Check: 10 + 14 = 24   There are 24 questions
10 * 3 + 14 * 5 = 30 + 70 = 100   The total number of points is 100.
Our answer is correct.
