The price that a company charged for a basketball hoop is given by the equation 50-x^2 where x is the number of hoops that are p

roduced, in millions. It costs the company $30 to make each basketball hoop. The company recently reduced its production to 1 million hoops but maintained its profit of 15 million dollars. Approximately how many basketball hoops did the company previously produce to make the same profit?

Answer: 2.125 million (Approx)

Step-by-step explanation:

Let the company initially produced x million hoops.

Therefore, after reducing 1 million hoops,

New number of hoops = (x-1)

Since, Profit = Sale price - Cost price

The cost price of 1 hoop = 30 dollars

Thus, the cost price of (x-1) million hoop = 30(x-1) dollars

According to the question,

The price that a company charged for a basketball hoop is given by the equation 50-(x-1)^2

Thus the sales price of x million hoops = 50 - (x-1)^2

Hence, the company's profit = (50 - (x-1)^2) - 30(x-1)

Again According to the question,

The company's profit = 15 million,

⇒ (50 - (x-1)^2) - 30(x-1)=15

⇒ 50-x^2-1+2x-30x+30=15

⇒ -x^2-28x+79-15=0

⇒ -x^2-28x+64=0

⇒ x^2+28x-64=0

By solving this equations we get,

x = -2(7+√65) and x = 2(√65-7)

But, the number of hoops can not be negative,

Thus, the initial number of  hoops = 2(√65-7) million =2.1245154966 million ≈2.125 million

Six teachers and 12 students volunteer for a committee to discuss extra-curricular activities. How many committees of 5 people c
Alex17521 [72]

Answer:

a)X=3300

b)Y=7770

Step-by-step explanation:

From the question we are told that:

Number Teachers T=6

Number Student S=12

Number in committee n=5

a) Generally the equation for exactly 3 students on the committee is mathematically given by

X=^{S}C_3*^{T}C_3

X=^{12}C_3*^{6}C_3

X=3300

b) Generally the equation for at least one teacher and at least one student on the committee is mathematically given by

Total Ways-(no of ways of selection no teacher or student)

Where total Ways

T=^{(6+12)}C_5

T=8568

Therefore

Y=8568-^{6}C_0*^{12}C_5+^{12}C_0*^{6}C_5

Y=8568-798

Y=7770

Jada created the two-way table below to describe the performance of her basketball team this season.
kramer
To answer the question, all the statements must be analyzed with the data presented in the table.
 From the table we get that the team played 16 games at home and 11 games away from home.
  In total, they played 27 games.
 Of the 16 games at home, the team won 6. Then, the proportion of games won at home is:
 6/16 = 0.375.
  Of the 11 games away from home, the team won 3. Then the proportion of games won away from home is:
  3/11 = 0.272.
  0.375 is not twice 0.272.
  Then the first statement is incorrect.

 The ratio of games won at home is 6/16 = 3/8. Therefore, the second statement is incorrect. The team does not win 3/5 of the games at home.
 The total number of games won is 9 and the total number of games is 27.
 So, the third statement is incorrect. The team does not win half of the games.
 The fourth statement is true. The team played 27 games

 The fifth statement is false because the team won more than 6 games. They won 3 games away from home and 6 games at home

 Finally, the sixth statement is correct, because the team lost 10 games at home and 8 away from home. However, the PERCENTAGE of games lost away from home is greater than the PERCENTAGE of games lost at home. Therefore, it is more likely that the team loses when playing away from home.

A supervisor records the repair cost for 17 randomly selected stereos. A sample mean of $66.34 and standard deviation of $15.22
expeople1 [14]

Answer:

Critical value: T = 1.337

The 80% confidence interval for the mean repair cost for the stereos is between $45.991 and $86.689

Step-by-step explanation:

We have the standard deviation for the sample. So we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 17 - 1 = 16

80% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 16 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.8}{2} = 0.9. So we have T = 1.337, which is the critical value

The margin of error is:

M = T*s = 1.337*15.22 = 20.349

In which s is the standard deviation of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 66.34 - 20.349 = $45.991

The upper end of the interval is the sample mean added to M. So it is 66.34 + 20.349 = $86.689

The 80% confidence interval for the mean repair cost for the stereos is between $45.991 and $86.689

il63 [147K]

Let x represent the number of quarts of Tuscan sauce and

y represent the number of quarts of marinara sauce Tiffany makes.

A quart of Tuscan sauce requires 6 tomatoes and 1 cup of oil

x quarts requires 6x tomatoes and 1x cups of oil

A quart of her marinara sauce requires 5 tomatoes and 1.25 cups of oil

y quarts requires 5y tomatoes and 1.25 y cups of oil

She has 45 tomatoes and 10 cups of oil on hand.

So the constraints are

6x + 5y

1x + 1.25y < = 10

x>=0 and y>=0
