Answers

Answer:

y=-7/4x+5

Step-by-step explanation:

The line contains points at (4,-2) and (0,-5)

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

(4,-2) =(x1,y1)

(0,-5) = (x2,y2)

(-2-5) / (4-0)

2) You need pi because of the circumference to calculate how long the perimeter is.
3) 113.1 = Area
4) You would need to adjust how many number places of pi you use for how huge the number you need to calculate for.
5) To write an exact number for an irrational expression you need to calculate then round to the nearest hundredths after you get the number for either radius, diameter, or area. To find the approximate value you only use the minimum numbers such as 3.14 instead of 3.14159...
6) How this helped me better estimate the value of an irrational expression is by using more numbers for every extra number place the circle has in the diameter.

A number is twice the other number. The sum of four times the smaller number and three times the larger number is 10. Find the numbers.

Please teach me how to do this. I'll give 90 points.

Answers

Answer:

1 and 2

Step-by-step explanation:

Let the first number be x

Let the other number be y

x = 2y.....eqn 1

From eqn 1, the smaller number is y while the bigger number is x.

3x + 4y = 10.... eqn 2

Substitute x = 2y into eqn 2

3(2y) + 4y = 10

6y + 4y = 10

10y = 10

Divide both sides by 10

y = 10/10

y = 1

Substitute y= 1 into eqn 1

x = 2y

x = 2(1)

x = 2

distribute than combine like terms

Elementary school A has implemented an after-school sports program and the principal would like to know if the participants of the sports program are becoming more active in general, compared to students who are not participating in the program. So the principal collected data on overall physical activities throughout the week from a group of the sports program participants and a group of school A students not in the program. The most appropriate statistical test for data analysis would be:_______.
A. Paired-samples t test
B. Independent-samples t test
C. Pearson's correlation
D. One-sample t test

Answers

Answer:

B. Independent-samples t test

Step-by-step explanation:

The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.

Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.

Thus, the best test to use in this case will be the Independent-samples t test
