Step-by-step explanation:

Learning math. The Core Plus Mathematics Project (CPMP) is an innovative approach to teaching mathematics that engages students in group investigations and mathematical modeling. After field tests in 36 high schools over a three-year period, researchers compared the perfor­mances of CPMP students with those taught using a traditional curriculum. In one test, students had to solve applied algebra problems using calculators. Scores for 320 CPMP students were compared with those of a control group of 273 students in a traditional math program. Computer software was used to create a confidence interval for the difference in mean scores (Journal for Research in Mathematics Education, 31, no. 3, 2000).
Conf. level: 95%

Variable: µ(CPMP) — µ(Ctrl)

Interval: (5.573, 11.427)

a) What is the margin of error for this confidence interval?

b) If we had created a 98% confidence interval, would the margin of error be larger or smaller?

c) Explain what the calculated interval means in this con­text.

d) Does this result suggest that students who learn mathe­matics with CPMP will have significantly higher mean scores in applied algebra than those in traditional programs? Explain.

what is 10 x 567 divded by 2 x 45

Answers

Answer:

63

Step-by-step explanation:

Answer: 63

Step-by-step explanation: First, you would do 10 x 567.

10 x 500 = 5000

10 x 60 = 600

10 x 7 = 70

5000 + 600 + 70 = 5670

Next, you find out 2 x 45.

2 x 45 is equivalent to 45 + 45.

45 + 45 = 90

Finally, you divide the product by the product - 5670 divided by 90.

The answer to that is 63.

f(x)=x^2−10x+21 in factored form

Answers

Answer:

(x-7)(x-3)

Step-by-step explanation:

The factored form of f(x)=x^2-10x+21 is (x-7)(x-3). In order to find the factored form, you have to find what values add to -10, yet multiply to 21. So, the values that add to -10 and multiply to 21 are -7 and -3. x and x multiply to x^2.

In conclusion, the factored form of f(x)=x^2-10x+21 is (x-7)(x-3).

What is m∠1? Help me, please

Answers

Answer:

32°

Step-by-step explanation:

Since the 147° angle and ∠2 form a Linear pair, sum of these angle must be 180°

147° + ∠2 = 180°

∠2 = 180° - 147°                       [subtracting 147° from both sides]

∠2 = 33°

Since all internal angles of a triangle add up to 180°,

∠1 + ∠2 + 115° = 180°

∠1 + 33° + 115° = 180°

∠1 + 148° = 180°

∠1 = 180° - 148°                       [subtracting 148 from both sides]

∠1 = 32°

What is the formula for finding the perimeter of a polygon?

Answers

Answer:

P=n*s

Step-by-step explanation:

n is the number of sides and s is the length of any one side.

Answer:

It depends on the polygon.

Perimeter is the distance around a figure, so the formula changes for what type of polygon it is. For example, a square would be 4l or the length of one side times 4.

To find the perimeter for any polygon, regular or irregular, use the distance formula for each side. Then add all values together.

The distance formula is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where [tex](x,y)[/tex] is one edge and [tex](x_2 , y_2)[/tex] is another edge, both belonging to the same side. This formula calculates the unit length of a side of your choice. For irregular figures, you have to use this formula for every side. For regular figures, just multiply the distance by how many sides there are.

A car rental company charges $34 per day for a rented car and $0.50 for every mile driven. A second car rental company charges $20 per day and $0.75 for every mile driven. What is the number of miles at which both companies charge the same amount for a one-day rental?

A.
56 miles

B.
54 miles

C.
36 miles

D.
24 miles

Answers

Answer:

B 2/3

Step-by-step explanation:

:)

First you want to make the equations for finding the total price of each rental car. We will say that x is the number of days and y is the number of miles. We will say the price for the first company is A = 34x + 0.50y and the second company is B = 20x + 0.75y. We want to find y where 34x+0.5y = 20x+0.75y and x=1. You should get 56 miles

The drama club sells tickets to their spring play. They sell 180 tickets for a
total of $2,248. Adult tickets cost $14 each. Student tickets cost $10 each.
How many adult tickets and how many student tickets do they sell?
Show your work.

Answers

The number of adult and student tickets are 112 and 68 respectively

How to determine the number of adult and student tickets?

Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.

Set up equations to represent the problem.

Let the A and S represent the numbers of adult and student ticket respectively. So we can write:

A + S = 180 --- (1)

14A + 10S = 2248  --- (2)

From (1):

A = 180 - S ----(3)

Put (3) in (2):

14A + 10S = 2248

14(180 - S) + 10S = 2248

2520 - 14S + 10S = 2248

2520 - 4S = 2248

4S =  2520 - 2248

4S = 272

S = 272/4

S = 68

Put S = 68 in (3):

A = 180 - S

A = 180 - 68

A = 112

One week before the performance, a parent complained to the school board that the play was inappropriate for middle school students. The school board agreed and contacted the principal, who then informed the classes that the show was canceled. Students were upset that their preparations were a waste. They believe they have the right to freedom of expression in performing the play. The school board said that students are minors and that it must approve decisions about what is presented in school by teachers or students. The students did not have time to plan a different show. A group of the students parents brought the case to court on their behalf, but they lost the case in state district court. The students parents appealed the district courts decision to their state court of appeals.
