A researcher wants to test the relationship between SAT scores and high school GPA. What statistic should be used

Answers

Answer 1

Answer: Pearson correlation statistic

Step-by-step explanation:

The Pearson Correlation statistic is used to measure linear association. It simply measures the statistical relationship that exists between two variables that are continuous. Information about both the magnitude and the direction are being provided by the Pearson Correlation statistic.

Since both the SAT scores and the high school GPA has to do with numbers, we are going to use Pearson correlation statistic. Spearman correlation are used for ranking.

2) A farmhouse shelters 61 animals. Some are cows and some are ducks. Altogether there are
208 legs. How many of each animal are there?

Answers

Answer:
43 cows and 18 ducks

Explanation:
Let c represent the number of cows in the farmhouse.
Let d represent the number of ducks in the farmhouse.

We know that:
- there are a total of 61 animals in the farmhouse
- one cow has 4 legs
- one duck has 2 legs
- there are a total of 208 legs

Using the information above, we can create two equations:

c+d=61
4c+2d=208

1) multiply the first equation by 2
If we do this, both equations will have 2d and we can subtract them to solve for c.

c+d=61
2c+2d=122

2) Subtract the first equation from the second

4c+2d=208
2c+2d=122
2c=86
c=43

Therefore, the number of cows in the farmhouse is equal to 43.

2) plug 43 into the first equation to solve for d
We can plug 43 into either of the original questions to find the number of ducks, but in this case, it would be easier to solve for in the first equation.

c+d=61
43+d=61
Subtract both sides by 43
43+d-43=61-43
d=18

Therefore, the number of ducks in the farmhouse is equal to 18.

Find the smallest number which is exactly divisible
by 15 20 and 30

Answers

Answer:

60

Step-by-step explanation:

The smallest number that is divisible by 15, 20 , and 30, must have the needed factors of each of these numbers:

15 = 3 * 5

20 = 2 * 2 * 5

30 = 2 * 3 * 5

Then the minimum common factor must have the following factors to satisfy the divisibility of all of the numbers above:

2 * 2 * 3 * 5 = 60

Step-by-step explanation:

8x+20=11x-31

We simplify the equation to the form, which is simple to understand  

8x+20=11x-31

We move all terms containing x to the left and all other terms to the right.  

+8x-11x=-31-20

We simplify left and right side of the equation.  

-3x=-51

We divide both sides of the equation by -3 to get x.

Height of the tower = 984 ft (opposite length)

Angle of elevation = 48° (reference angle)

Applying trigonometric ratios formula, we would have:

[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]

Plug in the values

[tex] tan(48) = \frac{y}{984} [/tex]

What is the circumference ​

Answers

Answer:

In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.

Step-by-step explanation:

Answer:

1. Circumference = 87.92

2.Circumference = 43.96

Step-by-step explanation:

The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92

The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96

Answers

Answer:

10 km

Step-by-step explanation:

volume of cube = s^3

1 m = 100 cm

volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3

Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.

1,000,000 cm = 10,000 m = 10 km

The Lakeside Cafe, famous for its misspelled sign saying, Chicken-Fried Stake, lost its roof in the storm. Amazingly, no employees or customers were injured. John Paxton, who was eating in the restaurant at the time, said, They told us there was no way to know if it was a tornado or not. Well, Ive never seen this kind of damage from anything but a tornado. Fallen limbs and downed power lines were also common problems across the city, blocking passage down dozens of streets.
