if the r-value, or correlation coefficient, of a data set is 0.854, what is the coefficient of determination to three decimal places?

Answers

Answer 1

To find the coefficient of determination, square the correlation coefficient:
(0.854)² = 0.729316. To three decimal places, this would be 0.729.

Answer 2

Answer with explanation:

Coefficient of determination(r²), is defined as, how well the data values are associated with each other when Regression line is drawn. In regression analysis, the coefficient of determination measures , how well the regression predictions approximate the real data points, means it measures the closeness between two variables.The Value of r², lies between 0 to 1. If value of r²=1, it shows ,regression line that is data values are Perfectly associated with each other.

If ,r²=0, it means there is no variation between two variables.There is 0% variation between two variables.

→Coefficient of Variation=[Correlation coefficient]²

=r²

=(0.854)²

=0.854 × 0.854

=0.729316

=0.730(Approx)

Dora is purchasing a $162,000 home with a 30-year mortgage at 5.15%. What is her monthly principal and interest payment?
A. $829.23
B. $884.56
C. $807.81
D. $876.09

Answers

Answer:

Option B is the answer.

Step-by-step explanation:

The formula for EMI is :

[tex]\frac{p\times r\times (1+r)^{n} }{(1+r)^{n} -1}[/tex]

Here p = 162000

r =[tex]5.15/12/100=0.004292[/tex]

n = [tex]30\times12=360[/tex]

Now putting the values in the formula we get,

[tex]\frac{162000\times 0.004292\times (1+0.004292)^{360} }{(1+0.004292)^{360} -1}[/tex]

[tex]\frac{162000\times 0.004292\times (1.004292)^{360} }{(1.004292)^{360} -1}[/tex]

= $884.60 close to option B.

So, option B is the answer.

Tubas, trombones and French horns are bass instruments. Fully stretched out, the length of a tuba is 18 feet. The length of a trombone is 8 13/14, and the length of a French horn is 17 3/14. The tuba is how much longer than the French horn? And the French horn is how much longer than the trombone?

Answers

What I would do is convert the fractions to decimals (just personal preference) making the trombone 8.93 feet and the french horn 17.21 feet. The tuba would be 0.79 feet longer than the french horn, and the french horn would be 8.23 feet longer than the trombone. However, if you need the answer to remain a fraction, the tuba would be 11/14 feet longer than a french horn, and a french horn would be 8 3/14 feet longer than a trombone.

The length of the Tuba is 11/14 feet longer than the length of the French horn.

The length of the French is 8 ²/₇ feet longer than the length of a Trombone horn.

What is subtraction?

It absolutely indicates subtracting something from a commodity, group, location, etc. Subtracting from an assemblage or a list of ways is known as subtraction.

Tubas, trombones, and French horns are bass devices. Fully pulled out, the measurement of a Tuba is 18 feet. The measurement of a trombone is 8¹³/₁₄ feet, and the measurement of a French horn is 17³/₁₄ feet.

The difference between the length of the Tuba and the French horn is given as,

⇒ 18 - 17 ³/₁₄

⇒ 18 - 241/14

⇒ (252 - 241) / 14

⇒ 11/14 feet

The difference between the length of the French and the Trombone horn is given as,

⇒ 17 ³/₁₄ - 8 ¹³/₁₄

⇒ 241/14 - 125/14

⇒ 116 / 14

⇒ 8 ²/₇ feet

The length of the Tuba is 11/14 feet longer than the length of the French horn.

The length of the French is 8 ²/₇ feet longer than the length of a Trombone horn.

Blake made and 87 on the first semester of algebra 1 . What score can he make on the second semester if he wants his average to be more than a 90 for both semesters? Answer using complete sentences

Answers

Blake must score an average of at least a 93 on his second semester to be able to have an average of 90 for both semesters.

Final answer:

In Mathematics, to find the average score which is more than 90 over two semesters when the first semester's score is 87, Blake needs to score more than 93 on his second semester.

Explanation:

In Mathematics, specifically algebra, finding an average involves adding up all the values and then dividing by the total number of values. In this case, we're trying to find out the minimum possible score Blake needs in the second semester in order for his total average to be over 90.

Let's denote the score in the second semester as 'x'. Since the average is calculated by (first semester score + second semester score)/2, and since Blake wants his average to be more than 90, we express this as:(87+x)/2 > 90.

We now solve for x: Multiply both sides by 2 to get; 87 + x > 180. Then subtract 87 from both sides to solve for x, which yields; x > 93.

Therefore, Blake needs to score more than 93 in his second semester to have an overall average greater than 90 for both semesters.

Mark raises guppies in an aquarium. He finds out that guppies reproduce very rapidly, and the number quadruples every month. He starts out with only 2 guppies, and the function y equals 2 times 4 to the x models the number of guppies he will have after x months. Which graph represents this function?

Answers

The graph of the function that models the reproduction of the guppies in the aquarium is of the exponent form, where its base is 4 and X is the exponent.
The domain of this function is the set of all real numbers and the range are all positive reals.
The function is close to zero for negative values of X, but for positive values it grows rapidly.
Below is a graph of the aforementioned function:
y = 2 * (4 ^ x)
For x between -1.5 and 0.5 and for x between -6.5 and 5.5

In this exercise we have to recognize the graphics given in the images and in this way identify which functions are being represented, in this way we have to:

What is the exponential function?

The exponential function represents a dependency relationship. In this type of mathematical operation there is a variable (unknown) in the exponent and the real number (greater than zero and different than one) in the base.

Chris visited the local Pizza Shack to purchase one pizza for each member of his Scout Troop. On arrival, he realised that he had mislaid the list he had made of the pizzas that had been requested. He knew that there were 32 people altogether and that all 3 vegetarians in the Troop wanted mushrooms only. He also remembered that the same number of people wanted just the chicken topping as wanted a plain pizza. Alex, a Young Leader, was able to help by recalling that: 12 people requested toppings that included chicken, 10 requested toppings that included pepperoni, 9 requested toppings that included mushroom, 1 person wanted all 3 toppings, 2 wanted chicken and pepperoni only, 2 wanted peperoni and mushroom only. What was the final order that Chris placed at Pizza Shack?

Answers

From the information provided in the question the following assumptions can be made;
32 people altogether
1 requested all three toppings
3 vegetarians got mushroom only
9 requested toppings with mushrooms included
12 requested toppings with chicken included
10 requested toppings that included pepperoni
2 wanted chicken and pepperoni only
2 wanted mushroom and pepperoni
x amount of people wanted chicken only
x amount of plain pizzas
all this information is depicted in the diagram attached

the amount of pepperoni only = 10 - 1 - 2 - 2
= 5
the amount of mushroom only (y)
the number of pizza with both chicken and mushroom (z)
y = 9 - 1 - 2 -z
= 6-z
amount of chicken toppings only
x = 12 - 2 - 1 - z
= 9-z
total number of pizzas
32 = 1 + 2 + 2 + 5 + y + x + z +x
= 10 + y + 2x +z
substiuting y = 6 - z
32 = 10 + 6 - z + 2x + z
32= 16 + 2x
2x = 16
x = 8
then x = 9-z
8 = 9-z
z = 1
and y = 6 - z
y = 5

therefore the final answer was supposed to be
8 plain pizzas
8 chicken only
5 pepperoni only
5 mushrooms only
1 all toppings
2 chicken and pepperoni
2 mushroom and pepperoni
1 chicken and mushroom

what is the slope of a line that is perpendicular to the line that passes through (1,0) and is parallel to y=3x+5

Answers

Slope is perpendicular to the line that passes (1, 0) & is parallel to y = 3x + 5

We need to first find the slope. Since we're already given an equation, we can simply find it within there :)

We're given an equation in slope intercept form (y = mx + b) so we can simply look in the "m" spot. Therefore, we know that the slope is 3.

Since our slope is perpendicular to the given line, we must find the negative reciprocal of the slope.

A negative reciprocal is simply a number flipped over and then given a negative (or a negative is removed).

An example is here : slope = 8 → negative reciprocal of slope = -1/8

So, our negative reciprocal of "3" is -1/3.

Therefore, our new slope is -1/3.

Now, since it passes through (1, 0) then this is how we are going to find out y-intercept to input it into our new equation.

y = mx + b

Simply plug in everything (including slope and y)

0 = (-1/3)(1) + b

Simplify.

0 = -1/3 + b

Add 1/3 to both sides.

1/3 = b

Therefore, our y-intercept is b.

Now that we have all of the needed variables for our new equation, simply plug everything into an all new equation :)

y = mx + b

y = -1/3x + 1/3

y 2 + 5y Choose the constant term that completes the perfect square trinomial.

Answers

Final answer:

The constant term that completes the perfect square trinomial is 6.25.

Explanation:

To complete the square for the given expression y² + 5y, we take half of the coefficient of the linear term (5/2) and square it to find the value to be added. Half of 5/2 is 5/4, and squaring it gives 25/16. Adding 25/16 to the expression yields a perfect square trinomial: y² + 5y + 25/16 = (y + 5/4)².

To write it in standard form, we convert 25/16 to 1.5625. Therefore, the constant term that completes the perfect square trinomial is 1.5625, or 6.25 when expressed as a decimal.
