Answer:

79.1

Step-by-step explanation:

Given that :

Mean, μ = 62

Standard deviation, σ = 5.7

The value, x that is +3 standard deviations from the mean :

x = μ + 3(σ)

x = 62 + 3(5.7)

x = 62 + 17.1

x = 79.1

Answer:

[tex]x=\frac{3}{4}[/tex]

Step-by-step explanation:

First, we know we want to get x all by itself. So, let's multiply it by 2.

[tex]\frac{2}{x}(2) = \frac{3}{4}(2)\\[/tex]

Then we have:

[tex]x=\frac{3}{4}(2)[/tex]

Now, we have to simplify the right side of the equation, so, let's rewrite it.

[tex]x=\frac{3*2}{4*2}[/tex]

All we have to do now is simplify.

[tex]x=\frac{6}{8}[/tex]

Luckily (and ironically) both the numerator and denominator are divisible by 2, so...

[tex]x=\frac{3}{4}[/tex]

Answer: 150 degrees

Step-by-step explanation:

The line around the angles that measure 35 degrees shows that those are equal so both are 35 degrees. Then you add 35+35+140. You then subtract that value from 360 since a whole circle measures 360 degrees.

Step-by-step explanation:

To define the time of flight equation, we should split the formulas into two cases:

Launching projectile from the ground (initial height = 0)

t = 2 * V₀ * sin(α) / g.

Launching projectile from some height (so initial height > 0)

t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

Answer:

[tex]P(Red) = 0.44[/tex]

Step-by-step explanation:

The question required a tree diagram (see attachment)

Required

Determine P(Red)

To do this, we simply each path that leads to red on the attached tree.

So, we have:

[tex]Red\ 1 = 0.35 * 0.6[/tex]

[tex]Red\ 2 = 0.45 * 0.2[/tex]

[tex]Red\ 3 = 0.20 * 0.7[/tex]

P(Red) is then calculated as:

[tex]P(Red) = Red\ 1 + Red\ 2 + Red\ 3[/tex]

[tex]P(Red) = 0.35 * 0.6 + 0.45 * 0.2 + 0.20 * 0.7[/tex]

[tex]P(Red) = 0.44[/tex]

Hence, the probability of selecting Red is 0.44

Answer:

18

Step-by-step explanation:

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or 0.15 x $65.00=$9.75.

So, the amount of tip you are going to leave is $9.75.

This makes the total cost of your meal: $65.00 + $9.75 = $74.75.

ANSWER: $74.75

Answer:

A.) 127.16π

Step-by-step explanation:

Volume of a cylinder = πr²h

Radius, r = 3.4m

Height, h = 11m

Pi = π

Find the volume in terms of pi

Volume of a cylinder = πr²h

= π * (3.4)² * 11

= π * 11.56 * 11

= 127.16π³

The correct answer is

A.) 127.16π

Answer: 60

Answer:

Option A

Step-by-step explanation:

C and D are scattered showing no pattern, Therefore, it is either A or B. I say it's not B due the the fact more studying minutes made even less test grades. So A is the only option left.

Answer:

z = 10x₁ + 8x₂ + 5x₃

Constraints are;

x₁ + 2x₂ + 2x₃ ≤ 1600

3x₁ + 2x₂ + x₃ ≤ 1700

x₁ ≥ 0

x₂ ≥ 0

x₃ ≥ 0

Step-by-step explanation:

There are three types of couches.

Let the first be x₁, second be x₂ and third be x₃.

We are told that the first type uses 1 foot of framing wood, The second type uses 2 feet of framing wood and the third type uses 2 feet of framing wood.

Thus, the first constraint will be;

x₁ + 2x₂ + 2x₃ ≤ A₁

Where A is the amount of framing wood that is available at hand.

Now, we are told that the factory produces 500 couches of the first type, 300 of the second type, and 200 of the third type each month.

Also that the framing wood is increased by 100.

Thus;

A₁ = (1(500) + 2(300) + 2(200)) + 100

A₁ = 1600

Thus,first constraint in full is;

x₁ + 2x₂ + 2x₃ ≤ 1600

For the cabinet wood, we are told that he uses 3 foot of cabinet wood, The second type uses 2 feet of cabinet wood and the third type uses 1 feet of cabinet wood.

Thus, the second constraint will be;

3x₁ + 2x₂ + x₃ ≤ A₂

Now, we are told that the factory produces 500 couches of the first type, 300 of the second type, and 200 of the third type each month.

Also that the cabinet wood is reduced by 600.

Thus;

A₂ = (3(500) + 2(300) + 1(200)) - 600

A₂ = 1700

Thus, full second constraint is;

3x₁ + 2x₂ + x₃ ≤ 1700

Now, for all these to work, x₁, x₂ and x₃ cannot be equal to or less than zero.

Thus, the third constraint is;

x₁ ≥ 0

x₂ ≥ 0

x₃ ≥ 0

We are told that the profit of the three couches are $10, $8, and $5 respectively.

Thus, the function to be maximized can be expressed as;

z = 10x₁ + 8x₂ + 5x₃

Step-by-step explanation:

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]

We know the radius = 12

and the height = 8

Substitute :

V = π12²[tex]\frac{8}{3}[/tex]

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]

Cancel the common factor - 3 :

V = [tex]2^4 * 8 * 3\pi[/tex]

Multiply 8 and 3π :

V = [tex]2^4 * 24\pi[/tex]

Solve the exponent :

V = [tex]16 * 24\pi[/tex]

Multiply :

V = [tex]384\pi[/tex]

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³
