if the sum of data is 80 and number of data 16,find the value of mean.​

Step-by-step explanation:

it seems the answer is c. 3514 in3

Approximate value of the volume of cylinder is equals to 3514 in³.

"Volume is defined amount of space occupied by any 3 dimensional body. It is useful to represents the capacity of any object ."

Formula used

Area of the base = πr²

Volume of a cylinder = area of the base × height

                                    = πr²h

Value of π = 3.14

According to the question,

Diameter of cylinder = 11 in

Radius (r)  = Diameter / 2

                = 11 / 2

                = 5.5 in

Height (h) = 37 in

Substitute the value in the formula we get,

Volume of cylinder = 3.14 ×(5.5)² × 37

                               = 3514.445 in³

                               ≈ 3514 in³

Hence, approximate value of the volume of cylinder is equals to 3514 in³.

Answer: 2

Step-by-step explanation:

Each cup of tea costs $10.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let consider X = cups of tea and Y= cup of hot chocolate

Therefore, the system of equation is,

3x + y = 12

x + 2y = 14

Solving;

-2(3x + y = 12)

-6x - 2y = -24

x + 2y = 14

Now, add;

-5x = -10

y = 2

Now substitute;

x + 2y = 14

x + 2(2) = 14

x = 10

Each cup of tea costs $10.

Answer:

[tex] m\widehat {AB} = 144\degree [/tex]

[tex]m\widehat {ACB} = 216\degree [/tex]

Step-by-step explanation:

Let the measures of the given arcs be 2x and 3x.

[tex] \because m\widehat {AB} \:\&\: m\widehat {ACB} [/tex] sums up to form a circle.

Therefore,

2x + 3x = 360°

5x = 360°

x = 360°/5

x = 72°

2x = 2*72 = 144°

3x = 3*72° = 216°

[tex] \therefore m\widehat {AB} = 144\degree [/tex]

[tex] \& m\widehat {ACB} = 216\degree [/tex]

Answer:

Mary is 8 and that Zane and Chase are both 4 years old.

Step-by-step explanation:

For this equation, we will say Mary = M, Zane = Z, and Chase = C.

We will now convert the word problem into equations.

[tex]2m = z, 2c - 4 = z, c = 4[/tex]

Now I will solve the equations by putting C into the equation.

[tex]2(4) = 8, 2(4) - 4 = 4, c = 4[/tex]

So we can see that Mary is 8 and that Zane and Chase are both 4 years old.

Given :

Emilie rides her bike x miles before she gets a flat tire.

She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.

To Find :

Which expression shows how many miles Emilie travels in all.

Solution :

We know, total distance covered is given by sum of all the distance she travelled.

Distance covered, D = x + 1/3 + 2 1/2

D = x + 1/3 + 5/2

D = (6x + 2 + 15)/6

D = (6x + 17)/6

Therefore, total distance travelled by Emilie is (6x + 17)/6 .

Answer:

Equation is  145 - 45 x = 10.

Billy bought 3 video games.

Step-by-step explanation:

As given,

Total Balance in the gift card = $145

The cost of each video game = $45

After purchasing , Balance in Gift card = $10

Now,

Let Total number of  video games Billy purchase = x

⇒Cost for video game = 45x

Now,

As we know ,

Total Balance - Purchased Item = Balance left

⇒ 145 - 45 x = 10

∴ The equation is 145 - 45 x = 10

Now,

145 - 10 = 45x

⇒135 = 45x

⇒ x = [tex]\frac{135}{45}[/tex] = 3

∴ we get

n - 66 = -35

n = 31

Answer:

31

Step-by-step explanation:

n-40-26= -35

n= -35+26+40

n= 31

first term: 5x-5y

common difference: -x/2 + y

The common difference is d = -0.5x + y and the first term is 5x-5y

The nth term of the geometric progression is expressed as:

[tex]T_n=a+(n-1)d[/tex]

where;

The fifth term of the sequence is expressed as:

[tex]T_5=a+4d=3x-y[/tex]

[tex]T_{11}=a+10d=3x-y[/tex]

Take the difference of the terms:

[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]

Get the first term:

a = 3x - y - 4(-0.5x+y)

a = 3x - y + 2x - 4y

a = 5x - 5y

Hence the common difference is d = -0.5x + y and the first term is 5x-5y

Answer:

The expression that matches the situation is 90.00 - 3x ⇒ 1st answer

Step-by-step explanation:

Let us solve the question

∵ You went to the mall with $90.00

→ That means the total money with you  = $90.00

∴ The total money = 90.00 dollars

∵ You bought three shirts that cost x dollars each

∴ The cost of a shirt = $x

∴ The number of shirts = 3

→ Find the total cost of the three shirts

∴ The cost of the shirts = 3 × x

∴ The cost of the shirts = 3x dollars

∵ The money left = the total money - the cost of the shirts

→ Substitute the value of total money and the cost of the shirts

∴ The amount of money left = 90.00 - 3x

∴ You have left with 90.00 - 3x dollars

∴ The expression matches the situation is 90.00 - 3x dollars

Step-by-step explanation:

It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that investment funds and/or investment companies may charge.
