Which point on the number line best represents the approximate value of
√23

Answer:

Strong positive correlation, 0.9663

Step-by-step explanation:

The value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

The value of the correlation coefficient can be found as;

r = -0.2984713607

After rounding off we get;

r = -0.2985

As the value of r is not close to the -1 therefore, the relation between x and y is weak negative.

Hence, the value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.

Answer:

The correct constraint is:

0 ≤ x ≤ 15

Step-by-step explanation:

The function given to us in the question is:

y = -2x² + 30x + 200

It is given that the function is at least 200, we can write is as:

-2x² + 30x + 200 ≥ 200  ⇒  Equation (i)

To find the constraint, replace ≥ sign with = sign and solve for x:

-2x² + 30x + 200 = 200

-2x² + 30x = 0

x(-2x + 30) =0

x = 0         ,      -2x + 30 = 0

x = 0         ,      -2x = -30

x = 0         ,       x = -30/-2

x = 0         ,       x = 15

So the end values of constraint are 0 and 15.

Take any value between 0 and 15 and substitute in equation (i) to see whether it satisfies the equation or not.

-2x² + 30x + 200 ≥ 200

Substitute x = 5 in the equation:

-2(5)² + 30(5) +200  ≥  200

-50 + 120 +200 ≥ 200

270 ≥ 200

As the equation satisfies. it means that the solution lies between 0 and 15, including the end values.

Hence.

Answer:

6.63 ft

Step-by-step explanation:

In this case we use pythagora's theorem which is

[tex]hyp^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]opp^{2}[/tex]

in this case, the hypotenuse (hyp) is the length of the ladder, the opposite (opp) is the height of the tree house and, the adjacent (adj) is the distance of the ladder's bottom to the base of the tree.

hpy = 12 ft

opp = 10 ft

adj = ?

substituting into the equation above, we have

[tex]12^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]10^{2}[/tex]

144 = [tex]adj^{2}[/tex] + 100

144 - 100 = 44 = [tex]adj^{2}[/tex]

the image is shown below

adj = [tex]\sqrt{44}[/tex] = 6.63 ft

Answer:

D) About 2,700 in^2

Step-by-step explanation:

Equation for area of a circle is A=3r² (it would usually be A=πr² but we are using the approximation)

The diameter is 60, we want to find the radius for the equation. We can use the equation d=2r to find the radius of the circle.

60=2r

30=r

Put radius into the area equation.

A=3(30)²

A=3(900)

A=2700

Answer:

2,700 in^2 ; Option D

Step-by-step explanation:

If it is known that the diameter of Circle B ⇒ 60 inches,

[tex]Diameter - 60 inches,\\\\Radius - 60 / 2 = 30 inches,\\\\Area of Circle B ( \pi stands for 3 ) - \pi * ( r )^2 = ( 3 ) * ( 30 )^2 = ( About ) 2,700 square inches\\\\Solution; 2,700 square inches[/tex]

( About ) 2,700 square inches; Option D

Answer:

x=1

Step-by-step explanation:

1. add 7/3x and 1/3x

2. subtract 5/3x because its the lowest number with a variable and you'll get 3/3x = 1

3. divide 3/3 from both sides (3/3) equals 1, so its 1/1 which is 1

4. x=1

Answer:

Yes

Step-by-step explanation:

In order to form a triangle sum of the lengths of any two sides must always be greater than the length of the third side.

Here,

6 + 5 = 11 > 8

5 + 8 = 13 > 6

8 + 6 = 14 > 5

Given side lengths satisfy above condition. Hence the given segment can form a triangle.

Answer:

A.

Step-by-step explanation:

1 radian = 180/π

So

Multiplying both sides by 25π/18

We'll get,

25π/18 (r) = (180/π)×(25π/18)

= (180×25)/18

= 10×25

Our first step is to get rid of the fraction by multiplying both sides by 3.

So in our second step we have x - 4 > -36.

Now add 4 to both sides to get x > -32.

Since x is greater than -32, the values that would

make this inequality true are -31 and 31.

Answer:

A). Surface area = 222 cm²

Volume = 180 cm³

B). Surface area = 375 cm²

Volume = 360 cm³

C). % increase in surface area = 67.57%

% increase in volume = 100%

Step-by-step explanation:

In the figure attached base of a prism has been given.

A). Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)

Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8

                                       = 30

Area of the base = 8×5 - 2×2 = 36 cm²

Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Volume of the prism = volume of the bigger prism - volume of the smaller prism cut off

                                  = 8×5×5 - 2×2×5

                                  = 200 - 20

                                  = 180 cm³

B). Surface area of the prism if it's height is 10 cm,

Surface area = 30×10 + 2×(36) = 372 cm²

Volume of the prism = 8×5×10 - 2×2×10

                                   = 400 - 40

                                   = 360 cm³                                      

C). Increase in surface area = 372 - 222 = 150 cm²

% increase in the surface area = [tex]\frac{150}{222}\times 100[/tex] = 67.57%

Increase in volume = 360 - 180 = 180 cm³

% increase in volume = [tex]\frac{180}{180}\times 100[/tex] = 100%

Answer: $80536.9

Step-by-step explanation:

From the question, at the end of a year, the total debt of a country stood at about $24 trillion and the country has a population of 298 million.

To calculate the amount in dollars per person, we divide the gross debt by the population. This will be:

= 24 trillion ÷ 298 million

= 24,000,000,000,000 ÷ 298 000 000

= 80536.9

The amount in dollar per person will be $80536.9

Answer: Then the sample space is 36.

Step-by-step explanation:

n is the number of possible combinations.

Now, as the die are of different colors, the case where:

white = 1 blue = 2, sum = 1+ 2 = 3

white = 2 blue = 1, sum = 2 + 1 = 3

are different.

So the number of possible combinations is:

6 options for the white dice and 6 options for the blue dice, so we have:

6*6 = 36 different combinations.

Then the sample space is 36.
