A scatter plot has a correlation coefficient of -0.159. What does this suggest about the relationship between the two variables?

Answers

r = -0.159 is the correlation coefficient

the value of r is closer to 0 than it is to -1, so the data is very weakly linear associated. The scatter plot points are too spread out for one single line to be close to them all. A different curve (such as a parabola) may be a better fit.

The fact that r is negative suggests that there is negative association. What this means is that as x goes up, y goes down. As you move from left to right, you go downhill. The regression line will have a negative slope.

Find the volume of a right prism with height h=10 cm, if: a The base is equilateral triangle with side 4 cm, base altitude of ≈ 3.5 cm. Help me!!!

If i walk 4 miles an hour how long will it take to walk 1 mile

Answers

Set up a ratio.

x= portion of 1 hour

4 miles/1 hour= 1 mile/ x hour
cross multiply
4 * x= 1 * 1
4x= 1
divide both sides by 4
x= 1/4 of an hour

To find number of minutes:

1 hour= 60 minutes

=1/4 of an hour * 60 minutes
=60/4
=15 minutes

ANSWER: It would take 1/4 of one hour ( or 15 minutes) to walk 1 mile.

Tammy and Wyatt are sales associates at the same used car dealership. Their supervisor is planning to promote the employee with the best sales numbers, on average. The box plots below show their sales, in thousands of dollars, for the past 2 weeks:

box plot labeled Tammy with min at 19, Q1 at 21, median at 25.5, Q3 at 26.75, max at 27.75. Box plot labeled Wyatt with min at 18.5, Q1 at 20.5, median at 24, Q3 at 27.5, max at 28.25

Who should get the promotion, and why?

A) Wyatt should get the promotion. His data is more evenly distributed, so his sales are more consistent.
B) Wyatt should get the promotion because he had the highest sales in a single day.
C) Tammy should get the promotion because her lowest value is higher than Wyatt's lowest value.
D) Tammy should get the promotion. She has a higher median with a smaller IQR, so her sales are better on average.

Answers

I think the answer is D. The other answers are unreasonable. Wyatt would not get the promotion and just because Tammy's lowest value is bigger than Wyatt's doesn't mean that Tammy gets the promotion. The only reasonable answer is D.

Answer:

Tammy should get the promotion. She has a higher median with a smaller IQR, so her sales are better on average.

Find 3 consecutive odd numbers where the product of the smaller two numbers is 46 less than the square of the largest number.

Answers

Answer: The numbers are: " 5, 7, and 9 " .
___________________________________________________

Explanation:
___________________________________________________
Let the "3 consecutive odd numbers" be represented by:
___________________________________________________
"x" ;
___________________________________________________
"x + 2 " ;
___________________________________________________
"x + 4 " ;
___________________________________________________
→ Solve for "x" ; and then solve for "(x + 2)" and "(x + 4)" .
___________________________________________________

The product of the smaller two numbers, is "46 less than" (the square of) the largest number:
___________________________________________________
→ " x* (x + 2) = (x + 4)² − 46 " ;
___________________________________________________
Note the "distributive property" of multiplication:
___________________________________________________
a(b + c) = ab + ac ;

a(b − c) = ab − ac .
___________________________________________________

Start with simplifying the "left-hand side" of the equation:
___________________________________________________

" x(x + 2)" = (x * x) + (x * 2 ) = (x² + 2x) ;
___________________________________________________
Then simplify the "right-hand side" of the equation:
___________________________________________________

" (x + 4)² − 46 " ;
___________________________________________________
→ (x + 4)² = (x + 4) (x + 4) ;

Note: " (a + b)(c + d) = ac + ad + bc + bd " .

→ (x + 4)² = (x + 4) (x + 4) = (x *x) + (x *4) + (4 *x) + (4 * 4) ;

= x² + 4x + 4x + 16 ;

= x² + 8x + 16;

→ Bring down the " − 46 " ;
___________________________________________________
→ x² + 8x + 16 − 46 ;

= x² + 8x + 16 − 46 ;

= x² + 8x − 30 ;
____________________________________________________
Now, rewrite the entire equation:
____________________________________________________

→ x² + 2x = x² + 8x − 30 ;

Subtract "x² " & "2x" from EACH SIDE of the equation:

→ x² + 2x − x² − 2x = x² + 8x − 30 − x² − 2x ;

to get:

→ 0 = 6x − 30 ;

→ 6x − 30 = 0 ;

Add "30" to each side of the equation:

→ 6x − 30 + 30 = 0 + 30 ;

→ 6x = 30 ;

Divide each side of the equation by "6" ;
to isolate "x" on each side of the equation; & to solve for "x" ;

→ 6x / 6 = 30 / 6 ;

to get;

→ x = 5 ;

→ "(x + 2)" = "(5 + 2)" = 7 ;

→ "(x + 4)" = "(5 + 4)" = 9 ;
______________________________________________________
Answer: The numbers are: " 5, 7, and 9 " .

shawna and amanda are selling pies for a school fundraiser. customers can buy cherry pies and pumpkin pies. shawna sold 1 cherry pie and 3 pumpkin pies for a total of $55. amanda sold 3 cherry pies and 3 pumpkin pies for a total of $69. what is the cost of each one cherry pie and one pumpkin pie?
PLEASE SHOW WORK

Answers

Let the cherry pies be c and the pumpkin pies be p:
Shawna: c + 3p = 55
Amanda: 3c + 3p = 69
We want to find the cost of c + p. To do this, the easiest way is to divide the second equation by 3:
(3c + 3p)/3 = 69/3
c + p = 23
Therefore, 1 cherry pie & 1 pumpkin pie cost $23.

if f(x) = x-1 and g(x) =2x-3 find the sum, difference, product and quotient of these two functions

Answers

We have the following functions:
f (x) = x-1
g (x) = 2x-3

For the sum we have:
f (x) + g (x) = (x-1) + (2x-3)
f (x) + g (x) = 3x - 4

For subtraction we have:
f (x) - g (x) = (x-1) - (2x-3)
f (x) - g (x) = -x + 2

For the product we have:
f (x) * g (x) = (x-1) * (2x-3)
f (x) * g (x) = 2x ^ 2 - 3x - 2x + 3
f (x) * g (x) = 2x ^ 2 - 5x + 3

For the quotient we have:
f (x) / g (x) = (x-1) / (2x-3)

Baby Kelsey wants to arrange 12 blocks in a row. How many different arrangements can she make?

Answers

Final answer:

To find the number of arrangements Baby Kelsey can make with 12 blocks, we calculate 12 factorial (12!), which equals 479,001,600. This represents the total number of unique ways to arrange the blocks in a row.

Explanation:

The student has asked how many different arrangements can be made with 12 blocks in a row. To determine the number of different arrangements, we use the concept of factorial, which is represented by an exclamation mark (!). In this case, we want to find 12!, which represents the product of all positive integers from 1 to 12.

Specifically, the calculation is 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1. This multiplication results in the number of unique ways to arrange the 12 blocks since each block is distinct and can be placed in any position within the arrangement.

Therefore, there are 479,001,600 different arrangements possible when organizing 12 unique blocks in a row, showcasing the vast number of combinations for even a small number of objects.

A package of cookies contains 6 cookies. Each package of cookies costs $1.49.

A function, f(x), is written to represent the cost of purchasing x packages of cookies.

What is the practical domain for the function f(x)?
A: all positive integers
B: all real numbers
C: all whole numbers that are multiples of 6
D: all whole numbers

Answers

Given are 6 cookies in a package.

Given that the cost of a package = 1.49 dollars.

Let's assume we purchase 'x' numbers of packages.

So, total cost of 'x' packages = '1.49x' dollars.

f(x) is the function that represents the cost of 'x' packages, i.e. f(x) = 1.49x

Since the number of packages can not be negative or can't be decimal numbers, so 'x' should be positive integral values.

So, the practical domain of f(x) would be "positive integral values".

Hence, option A is correct, i.e. "all positive integers".

There are a couple of ways of doing this to show there there is just one solution. The most easily done way is to graph the quadratic. I have done that for you.

Notice that the quadratic touches the x axis, it does not cut it in two places or no places. When a quadratic just touches the x axis, it has only one solution.

Method 2
The quadratic is shown in the vertex form. If there was a number outside he bracket showing squares then you would get

y = (-x + 4)^2 + 4 (drawn in blue)
y = (-x + 4)^2 - 6 (drawn in green)

These two examples show what the vertex form would look like if the axis was cut in 2 places or no places and there would be no solution for the first one and 2 places for the second one.

Answers

The input to a trig function is definitely an angle (whether in degrees or expressed in radians). That angle is also "a central angle of a circle."

Answer: A central angle of a circle

Step-by-step explanation:

The trigonometric functions are also known as circular functions.

The two fundamental trigonometric functions are defined as the coordinates of a any point A travelling around on the unit circle of radius 1 .

The input variable in trigonometric functions is the central angle of the circle 'x' such that we get sin x and cos x which give the x and y coordinates of A.

Hence, the input to a trigonometric function is a central angle of a circle.

A fish tank in the shape of a rectangular prism has these dimensions: length = 20 inches width = 10 inches height = 12 inches What is the volume of water in the tank when it is 45 full?

Answers

Final answer:

The volume of water in the fish tank when it is 45% full is 1080 cubic inches.

Explanation:

To find the volume of water in the tank when it is 45% full, we first need to calculate the volume of the tank.

The formula for the volume of a rectangular prism is length × width × height.

Given that the length is 20 inches, the width is 10 inches, and the height is 12 inches, we can substitute these values into the formula: 20 × 10 × 12 = 2400 cubic inches.

Next, we need to find 45% of this volume. To do this, we multiply the volume by 0.45: 2400 × 0.45 = 1080 cubic inches.

Therefore, the volume of water in the tank when it is 45% full is 1080 cubic inches.
