Answer:

Seems to be no correlation at all.

Answer:

anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).

The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.

For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.

It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.

The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.

Answer:

question what number is on the top or bottom of the parallelagram

Step-by-step explanation:

and what is on the left or right of the parallorgram I need to know to help you

The area of the parallelogram will be 98 square feet.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

Let h be the perpendicular distance between the parallel side and b be the length of the base of the rectangle.

Then the area of the parallelogram will be given as,

Area of parallelogram = b x h

The length of the base of the parallelogram is 14 feet, and the value of h is 7 feet.

Then the area of the parallelogram will be

Area pf parallelogram = 14 x 7

Area pf parallelogram = 98 square feet

Then the area of the parallelogram will be 98 square feet.

The complete question is given below.

Answer:

everything is in the photo

Answer:

$(a + b) + cn cent

Step-by-step explanation:

Given :

Fixed charge = $a

Rent of a meter = $b

Charge per unit of electricity = c cents

The total cost of using n units of electricity :

For n units of electricity ;

Fixed charge is paid once

Meter rent is paid once

The cost of electricity = (number of units * cost per unit) = (n * c) = nc cents

Total cost of n units of electricity :

$(a + b) + cn cent

If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. The second digit to the right of the decimal point indicates the number of hundredths.  

In this case the .3 indicates 3/10ths of a kilogram.  or 300 grams!

In the other case 0.03 indicates 3/100ths of a kilogram or 30 grams!

So, to compare the two:

the tenths decimal is 10 times bigger than the decimal in the next spot (hundredths)

Hope this helps!

y=2( x - [tex]2^{2}[/tex])-2

Step-by-step explanation:

Use the vertex form,  y=a(x - [tex]h^{2}[/tex])+k to determine the values of A,H,K

a=2

h=2

k=   -2

Since the value of a is positive the parabola opens up.

Answer:

Step-by-step explanation:

The "trick" to this problem is knowing that opposite sides of the box add up to 180°

Now that you know that maybe you can solve this?

180= 7x+2 + 6x-4

180 = 13x -2

182 = 13x

14 = x

find y now to find all the angles

180 = 2y + 4 +4y - 4

180 = 6y

30 = y

now solve the x expressions and the y expressions

7x+2

7(14)+2

98 + 2

D= 100°

6x-4

6(14)-4

84-4

B = 80°

A = 64°

Choices given as [tex]2^{16}, 4^8[/tex] and [tex]16^4[/tex] are correct.

Step-by-step explanation:

Given expression is,

[tex](4^5)(4^3)[/tex]

By applying law of exponents in the given expression,

[tex](4^5)(4^3)=4^{5+3}[/tex]

            [tex]=4^8[/tex]

[tex](4^5)(4^3)=(2^2)^5(2^2)^3[/tex]

            [tex]=(2^{2\times 5})(2^{2\times 3})[/tex]

            [tex]=2^{10}\times 2^6[/tex]  

            [tex]=2^{16}[/tex]

            [tex]=(2^4)^4[/tex]

            [tex]=(16)^4[/tex]

Therefore, choices given as [tex]2^{16}, 4^8[/tex] and [tex]16^4[/tex] are correct.

Answer:

17 * 2 = 34

-10 + (-9) = -19 or -29 + 10 = -19

Step-by-step explanation:

For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!

17*2 = 34 ✔

For the second, mess around with a few numbers add +10 and -29,  COUNT DOWN from 10 and -29.

since + + + = + then - + - = -

if 10+9=19 then do the same with -

-10 + (-9) =-19

[tex]x = \frac{9}{7} [/tex]

Step-by-step explanation:

Reason :

[tex]4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7} [/tex]

Therefore

[tex]x = \frac{9}{7} [/tex]

Step-by-step explanation:

2x+5=3x-12

or, 2x-3x=5-12

or, -x= -7

i.e X=7

again

y+4=3x+2

or, y+4=3*7+2

or, y+4=21+2

or, y+4=23

or, y =23-4

i.e y = 19

hence, the value of X is 7 and y is 19

First convert 4.5 hours to minutes

4.5 hours = 270 minutes

6:30 = ?:270

Divide 270 and 30

270/30 = 9

Then multiply 6 and 9

9*6 = 54

The event planner can set up 54 tables in 4.5 hours(270 minutes)

Answer:

The surface area of the shape is 292 in^2

Step-by-step explanation:

Here, we want to find the surface area of the cuboidal shape

Mathematically, the area of a cuboid can be calculated using the formula;

A = 2(lb + lh + bh)

where l is the length which is 7 inches

b is the breadth which is 6 cm

h is the height which is 8 cm

Substituting these values, we have

A = 2((8 * 6) + (7 * 6) + (8 * 7))

A = 2(56 + 42 + 48)

A = 2 * 146

A = 292 in^2
