Analyze the following statement: Marcus notices that he runs faster in the mornings rather than the evenings. Is the statement an example of correlation or causation?
A. Correlation, because time of day doesn't cause a person to run faster or slower B. Causation, because Marcus has noticed this over several trials
C. No relationship, because time of day has nothing to do with how fast a person runs
D.There is not enough information to make a conclusion

Answers

Answer 1

The answer is option A "Correlation, because time of day doesn't cause a person to run faster or slower." It's completely logic that the time of day doesn't affect the persons speed it's how fit the person that person is would effect his or her speed. Correlation is two data sets that are close together and are connected on a graph.

Hope this helps!

Answer 2

Answer:

A. Correlation, because time of day doesn't cause a person to run faster or slower

Step-by-step explanation:

Marcus notices that he runs faster in the mornings rather than the evenings.This is a correlation because it tells us about the relationship of Marcus's running speed with respect to the time of day. The causation is not possible because there is no definite mention for the increase in speed.

Hence, option A is the answer.

draw and label an example of two parallel lines that are perpendicular to a third line.

Answers

Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite. He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to (that is, they will be supplementary). Such angles are called same-side interior angles:

A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area of the kite.

Answers

Height of the kite is = 36 inches.

Width of the kite is = 30 inches

One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .

Now we will use the formula [tex]area=\frac{1}{2}*base*height[/tex] to find the area of each triangle. Then we will add both the areas to find the area of the kite.

Area of 1 triangle = [tex]\frac{1}{2}*36*15[/tex] = 270 square inches

Area of the 2nd triangle is also = 270 square inches

Hence, area of the kite = 270+270 = 540 square inches

The area of the kite is 540 square inches

The dimension of the rectangle is given as:

Height = 36 inches. Width = 30 inches

The area of the kite is then calculated using:

[tex]Area = \frac 12 \times (Height \times Width)[/tex]

Substitute values for Height and Width

[tex]Area = \frac 12 \times (36 \times 30)[/tex]

Evaluate the expression in bracket

[tex]Area = \frac 12 \times 1080[/tex]

Evaluate the product

[tex]Area = 540[/tex]

Hence, the area of the kite is 540 square inches

A single die is rolled twice. find the probability of rolling an odd number and a number greater than 4 in either order.

Answers

The probability of rolling an odd number and a number greater than 4 in either order is 1/6.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, a single die is rolled twice,

∴ The 36 outcomes are

(1,1),(1,2)...(1,6),(2,1)...(2,6),(3,1)...(3,6),(4,1)...(4,6)...(5,1)...(5,6)...(6,1)...(6,6).

So, N(S) = 36.

The no of favorable outcomes N(F) an odd number and a number greater than 4 in either order are [{(1,5),(1,6),(3,5)(3,6),(5,5),(5,6)} as given they can occur in either order so (1,5) and (5,1) are one combined.

∴ N(F) = 6.

So, The probability P(F) of rolling an odd number and a number greater than 4 in either order is,

P(F) = N(F)/N(S).

P(F) = 6/36.

P(F) = 1/6.

The probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice is 1/18.

To find the probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice, we need to first identify the possible outcomes. The odd numbers on a die are 1, 3, and 5. Since we are also looking for a number greater than 4, the only possible outcomes that meet both conditions are 5 and 6.

When the die is rolled twice, there are 6 x 6 = 36 possible outcomes. There are two favorable ways to achieve the goal: Roll a 5 (odd) first and then a 6 (greater than 4), or roll a 6 first and then a 5. Thus, there are two successful outcomes: (5, 6) and (6, 5). The probability of each individual outcome is 1/36, so the combined probability is 2/36, which simplifies to 1/18.

Therefore, the probability of rolling an odd number and a number greater than 4 in either order with a single die rolled twice is 1/18.

The result of rounding the whole number 53,679,012 to the nearest millions place is: 53,000,000. 50,000,000. 53,600,000. 54,000,000.

Answers

To round it to the nearest millions place it would be 54,000,000

Final answer:

The number 53,679,012 rounded to the nearest million is 54,000,000. The digit in the hundred thousands place determines whether to round up or down. In this case, since it's a 6 (which is >= 5), we round up.

Explanation:

Rounding Whole Numbers to the Nearest Million

To round the whole number 53,679,012 to the nearest million, we need to look at the digit in the hundred thousands place, which is 6. Since this digit is 5 or greater, we round up. Therefore, we increase the digit in the millions place by one, giving us 54,000,000 as the rounded number to the nearest million.

For example, consider another number like 52,700,000. Using the same rounding principle, since the digit in the hundred thousands place is 7, which is greater than 5, we would round up to 53,000,000.

When rounding large numbers, the key is to look at the digit immediately to the right of the place value you are rounding to. If this digit is 5 or higher, you round up, and if it is 4 or lower, you round down.

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates over the next several months. Drake is planning to take the class 6 weeks from now, so he plans to save $125 each week. Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470. He knows that he must adjust his plan in order to meet his goal. Drake came up with the following options: Option A: Stay with saving the original amount each week but take the class a week later than originally planned. Option B: Increase the amount of money he saves each week by $15 from his original plan. Which of the following is a true statement? a. Only option A will allow him to meet his goal. b. Only option B will allow him to meet his goal. c. Both options A and B will allow him to meet his goal. d. Neither option A nor option B will allow him to meet his goal.

Answers

The answer here is C. both options will allow him to meet his goal. hope this helped

answer- C

total money required = 750

total money saved = 470

weeks left = 2

money earned in each week = 125

money earned in 2 weeks = 250

470 + 250 = 720( so, drake is short of 30 )

option A- by postponing the classes for 1 week, he will earn 125 more, so it is an option to meet his goal as 125>30

option B- by increasing the savings by 15 for two weeks, he will save 30 more which is the amount drake needs. so , it is also a good option

Answers

If we want to find 60% of 60, we can solve by multiplying 60 by 0.6.

60 x 0.6 = 36

If we wanted to do it another way, we could multiply 60 by 0.5 and 0.1 seperately and add those numbers up.

You're looking for a number [tex]x[/tex] such that

[tex]\dfrac x{60}=\dfrac{60}{100}=60\%[/tex]

Multiply both sides by 60, so that

[tex]\dfrac{60x}{60}=\dfrac{60^2}{100}\implies x=\dfrac{3600}{100}=36[/tex]

Another way of doing it: you can easily find that 10% of 60 is 6. Then 60% would be 6 times 10%, and 6 times 6 is 36.

What is Volume?

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill. Volume is a three-dimensional quantity used to calculate the capacity of a container.

Given:

Base of the triangle (b) = 12.3 mm

Height of the triangle (h) = 8.2 mm

Length of the prism (l) = 20.5 mm

So, the volume of the triangular prism formula:

= 1/2 x b x h x l

= 1/2 x 14.4 x 2.1 x 8.25

= 7.2 x 2.1 x8.25

3n = 5d and 2n - 4 = d - 2

Answers

You probably missed that when the numerator and denominator are both decreased by 2, the new fraction is now equal to 1/2.

The numerator of the fraction is "n" and the denominator of the fractions is "d". Initially the numerator and denominator are in the ratio 3 to 5. In equation form we can state this as:

[tex]n:d=3:5 \\ \\ \frac{n}{d}= \frac{3}{5} \\ \\ 5n=3d [/tex]

When both numerator and denominator are decreased by 2, the new numerator will be n-2 and denominator will be d-2. These numerator and denominators are in ratio 1 to 2. In equation form we can write this as:

[tex]n-2:d-2=1:2 \\ \\ \frac{n-2}{d-2} = \frac{1}{2} \\ \\ 2(n-2)=1(d-2) \\ \\ 2n-4=d-2 [/tex]

This is our second equation. Thus the two equation which can be used to solve the problem are:

5n = 3d

(Use PI = 3.14)

Answers

3.14*9^2=254.469

answer: 254.469

The meaning of the area is the measurement of a surface in this case a circle, which can be find by using the formula A=πr^2, where r is equal to the radius of the circle.

On this exercise is given that the radius of the circle is 9 cm and it is asked to find its area and use 3.14 as the value of π. Therefore, to find the area of the circle you should substitute the value of the radius and the value of pi into the formula A=πr^2.

A=πr^2
A=(3.14)(9)^2
A=(3.14)(81)
A=254.34
