A correlation coefficient of .89 indicates that _____.
Answers
The correlation coefficient indicates the strength of the relationship between variables. The closer it is to 1, the stronger the relationship. If it is 0, there is no relationship.
Explanation:The number portion of the correlation coefficient indicates the strength of the relationship. The closer the number is to 1 (be it negative or positive), the more strongly related the variables are, and the more predictable changes in one variable will be as the other variable changes. The closer the number is to zero, the weaker the relationship, and the less predictable the relationships between the variables becomes. For instance, a correlation coefficient of 0.9 indicates a far stronger relationship than a correlation coefficient of 0.3. If the variables are not related to one another at all, the correlation coefficient is 0.

Answers
what percent of the pies were apple...
3/16 = 0.1875 = 18.75% <=
Answer:
18.75%
Step-by-step explanation:
Mr. Potts, the college Pastry Chef baked pies for the student fundraiser.
He baked apple pies = 3
Blueberry pies = 2
Cherry pies = 5
Key lime pies = 6
We have to calculate the percentage of the apple pies.
Total number of pies that he baked = 3 + 2 + 5 + 6 = 16 pies
Percentage of Apple pies = [tex]\frac{3}{16}[/tex] × 100
= 0.1875 × 100
= 18.75%
18.75% was apple pie.

Answers
d = C / pi
d = 44 / 3.14
C = 14
answer
b. 14 in
Answer:
The diameter of the circle is 14in
Step-by-step explanation:
There is an equation that says: If you have the circumference (C) of a circle you can get the Diameter (d):
d=C/π(constant number)
In the problem you have C=44 in
Then:
π=3,1416
d=44in/3,1416
d=14in
If the population decreases with a constant rate of change and the decrease is 7% in the first year, what will the town's population be in 6 years? (round to the nearest person)
Answers
If the population decreases with a constant rate of change and the decrease is 7% in the first year.
The decrease in the population of the town in the first year is given by 0.07 x 33,000 = 2,310
The decrease in the population of the town in 6 years is given by 2,310 x 6 = 13,860
Therefore, in 6 years, the town's population will be 33,000 - 13,860 = 19,140

19 is the base. 3 is the exponents.
Both powers have the same base, 19, so write the same base, 19 and add 3 + 3 for the exponent.
Also, there is no need to write "exponent".
Use the symbol ^ (shift-6) to mean exponent.

In a biology lab, a student has measured the lengths of 30 palmetto bugs in inches. he computes the mean and standard deviation as 4.1 inches and 1.2 inches, respectively. he later finds out that he was supposed to calculate the mean and standard deviation in centimeters instead of in inches. what is the new standard deviation of his sample, in centimeters? (note: 1 in = 2.54 cm)
Answers
Solution:
Mean = 4.1 inches x (2.54 cm/1 inch) = 10.41 cm
Standard deviation = 1.2 inches x (2.54 cm/1 inch) = 3.05 cm
ANSWERS: Mean = 10.41 cm; Standard Deviation = 3.05 cm

The sum of three numbers is 142. The first number is 8 less than the second. The third number is 4 times the second. What are the numbers?
Answers
x + y + z = 142
x = y - 8
z = 4y
y - 8 + y + 4y = 142
6y - 8 = 142
6y = 142 + 8
6y = 150
y = 150/6
y = 25 <=== the 2nd number
x = y - 8
x = 25 - 8
x = 17 <== the 1st number
z = 4y
z = 4(25)
z = 100 <=== 3rd number

Answers
Here are the steps:
Expand:
12x+9=7x-13
Subtract 9 from both sides:
12x+9-9=7x-13-9
Subtract 7x from both sides:
12x-7x=7x-22-7x
Simplify:
5x=-22
Divide both sides by 5:
5x/5=-22/5
Simplify:
x=-22/5
Thus, x=-22/5.
The solution to the given-equation represented by "3(4x + 6) = 9x + 12" is : (b) x = -2.
To find the solution to the equation 3(4x + 6) = 9x + 12, we simplify and solve for x,
First, we distribute the 3 to both terms,
12x + 18 = 9x + 12
Next, we separate variable-term by subtracting 9x from both sides:
12x - 9x + 18 = 9x - 9x + 12,
Simplifying further:
We get,
3x + 18 = 12,
Next, we separate "x" by subtracting 18 from both sides,
3x + 18 - 18 = 12 - 18,
3x = -6,
(3x) / 3 = (-6) / 3,
x = -2
Therefore, the correct answer is (b) x = -2.

how many liters of a 20% acid solution must be mixed with a 50% acid solution to obtain 12 liter of a 30% solution?
Answers
Let x = amount of 20% acid solution
Let y = amount of 50% acid solution.
The equation for the solution:
You want a total of 12 liters, so
x + y = 12
The equation for the acid:
The 20% solution has 20% acid, so in x liters of the 20% solution, you have 0.2x liters of acid.
The 50% solution has 50% acid, so in y liters of the 50% solution, you have 0.5y liters of acid.
The combined solution is 12 liters of 30% acid, so it has 30% * 12 liters of acid = 3.6 liters of acid.
0.2x + 0.5y = 3.6
Now you solve the two equations in a system of equations.
x + y = 12
0.2x + 0.5y = 3.6
Multiply the second equation by 10:
2x + 5y = 36
Multiply the first equation by -2:
-2x - 2y = -24
Add the last two equations:
3y = 12
y = 4
Substitute y = 4 in the first original equation:
x + y = 12
x + 4 = 12
x = 8
Answer: 8 liters of 20% solution and 4 liters of 50% solution.
