-0.89 (i think)

Step-by-step explanation:

Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89

If its wrong then i'm not a smart person, and it's -0.15

Answer:

V = 396 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A = [tex]\frac{1}{2}[/tex] bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³

Answer:

Sale Price = $36

Step-by-step explanation:

To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.

Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36

Answer:

x= 7 1/2

Step-by-step explanation:

Subtract the 1/2 to get it out of the way (whatever you do on one side of the = sign you have to do to the other)

So 10- 1/2= 9 1/2

Subtract the 2 to get it out of the way

9 1/2-2=

7 1/2

Answer:

4,000

Step-by-step explanation:

To round a number, take the place next to the one you wish to round and look to see if it is four or under, or five or up. In this case, 2 is less than 5 so we will be rounding down towards the nearest integer, which is 4. Also, all places after the place value you round will become zero. So, 4,000 rounded to the thousands place is 4,000.

hope this helps :)

Answer:

The answer would be 4,000

Step-by-step explanation:

even if you round it up the the nearest hundred, it would still be 4,000.

Answer: C

Step-by-step explanation:

4/8 ×3/1

The solution tothe logarithmic function log₃([3x+2] = log₃(4x - 6) is 8

Given the logarithm expression

log(3)[[3x+2] = log(3)[4x - 6]

The logarithm on both sides of the equation will cancel out to have:

3x + 2 = 4x - 6

Collect the like terms

3x - 4x = -6 - 2

-x = -8

x =8

Hence the solution tothe logarithmic function log₃([3x+2] = log₃(4x - 6) is 8

Answer:

192π

Step-by-step explanation:

cylinder volume is base times height

2πr^2 = base = 64π

height = 3

64π*3 = 192π

The volume of the given cylinder is 192π cubic units. Therefore, option C is the correct answer.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

From the given figure, radius of a cylinder = 8 units and radius of a cylinder = 3 units.

We know that, volume of a cylinder is πr²h.

Now, volume = π×8²×3

= π×64×3

= 192π cubic units.

Therefore, option C is the correct answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

It is given that the area of a circle is 36.43cm² and we have to find the length of the radius.

So, first of we must know this formula :

⇒ πr² = Area(Circle)

Now, Substituting the given values in the formula :

⇒ 3.14 × r² = 36.43

⇒ r² = 36.43/3.14

⇒ r² = 11.60

⇒ r = √11.60

⇒ r = 3.40

Therefore,

Hey ! there

Answer:

Step-by-step explanation:

In this question we are given with area of circle that is 36.43 cm² . And we are asked to find the length of radius of circle rounded to two decimal points .

We know that ,

[tex] \qquad \quad \frak{Area_{(Circle)} = \pi r {}^{2} } \quad \bigstar[/tex]

Where ,

Solution : -

According to question , area of Circle is equal to 36.43 . So ,

[tex] \longrightarrow \qquad \: \pi r {}^{2} = 36.43[/tex]

Step 1 : Substituting value of π :

[tex] \longrightarrow \qquad \:3.14 \times r {}^{2} = 36.43[/tex]

Step 2 : Transposing 3.14 to right side :

[tex] \longrightarrow \qquad \: r {}^{2} = \cancel{\dfrac{36.43}{3.14} }[/tex]

On dividing 36.43 by 3.14 , We get :

[tex] \longrightarrow \qquad \: r {}^{2} = 11.60[/tex]

Step 3 : For removing square from r , We are applying root on both sides :

[tex] \longrightarrow \qquad \: \sqrt{r {}^{ 2 }} = \sqrt{ 11.60}[/tex]

We get :

[tex] \longrightarrow \qquad \:r = \sqrt{11.60} [/tex]

Step 4 : Finding square root of 11.60 , We get :

[tex] \longrightarrow \qquad \: \purple{\underline{\boxed{\frak{r = 3.40 \: cm}}}} [/tex]
