Answer:

9\(\pi\) or 28.26

Step-by-step explanation:

A = \(\pi\)r^2

the diameter is 6, making the radius 3 (radius x 2 = diameter)

A = 3^2 x \(\pi\)

A = 9\(\pi\) or 28.26

Answer:

8 ft

Step-by-step explanation:

Given:

Volume = 401.92

radius = 4 feet

Volume of cylinder: \(\pi\)r^2h

3.14 * 4^2 * h = 401.92 cubic feet

3.14 * 16 * h = 401.92 cubic feet

50.24 * h = 401.92

h = 8 ft

Answer:

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23

Answer:

f(4)=23

Step-by-step explanation:

1.f(4)=4(4)+7

2.f(4)=16+7

3.f(4)=23

Answer:

816.67

Step-by-step explanation:

To find what needs to be added subtract the two numbers:

19/21 - 11/21 = 8/21

You need to add 8/21 to 11/21 to get 19/21

Answer:

90/100 or 81.8%

Step-by-step explanation:

w = 0,1 , then your grade will be 81

It depends upon how many total points are available and what the zero was out of possible points. If you have a 90/100 and a 0/100, that gives you a 45%, which is failing. If you have 90% of 1000 points and get a 0/100, that will land you with an 81.8%.

Here are some equations and their corresponding solutions:

x^2 - 9 = 0: This equation has two solutions, x = 3 and x = -3, both of which are real. So it has both a positive and a negative solution.

x^2 + 4 = 0: This equation has no real solutions, because the square of a real number is always non-negative. So it has no positive, negative, or zero solution.

5x - 2 = 0: This equation has one solution, x = 0.4, which is positive. So it has a positive solution.

-2x + 6 = 0: This equation has one solution, x = 3, which is positive. So it has a positive solution.

x - 7 = 0: This equation has one solution, x = 7, which is positive. So it has a positive solution.

The reasons for these solutions can be found by analyzing the properties of the equations. For example, the first equation is a quadratic equation that can be factored as (x-3)(x+3) = 0, which means that the solutions are x = 3 and x = -3. The second equation is also a quadratic equation, but it has no real solutions because the discriminant (b^2 - 4ac) is negative. The remaining equations are linear equations, and they all have one solution that is positive.

The value of (ΣX)² for the scores 1, 5, 2 is:  

64

It is the representation of the sum of infinite or many values. And it is represented by the following symbol:

∑xi

The value of (ΣX)² for the scores 1, 5, 2 can be found by first finding the summation of the scores and then squaring the result.

Steps to follow:

Step 1: Find the summation of the scores.
            ΣX = 1 + 5 + 2 = 8

Step 2: Square the summation.
            (ΣX)² = 82 = 64

Therefore, the value of (ΣX)² for the scores 1, 5, 2 is 64.

The vertical line test is a visual test to determine if a graph represents a function; since a function can only have one output for every input if a vertical line intersects a curve in more that one point the it is not the graph of a function.

In this case we any vertical line will only intersect one point then we conclude that:

The graph represents a function. Using the vertical line test, the graph intersects any vertical line at only one point.

Answer: The answer is 38%

Answer:

x = 54

Step-by-step explanation:

In this line, I am going to assume lines l and m are parallel.

Each flat surface is half of a circle, therefore it has 180 degrees. We are given one side and told to find the other.

180 - 116 = 64.

The other angle's total value must be 64.

Now, to solve for x, subtract 10 from 64 [inverse operations].

64-10=54

The value of x in this equation is 54 degrees.

The shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

What is a normal distribution?

A normal distribution is a function on some random variables, which represent the set of all those random variables in a symmetrical bell shape about the mean value.

It shows that the probability of occurrence of some data which is distributed over a function is more at or around the mean.

It is also known as probability distribution curve.

The normal distribution has two parameters:

What is the shape of the normal distribution?

The normal distribution curve is at it's peak at the mean value. This shows that the probability of occurrence of the data or value is more concentrated or distributed about the mean. It is also symmetric about the mean. As we more further from the mean, we see that the normal distribution curve gradually decreases showing that the probability of occurrence of the data or the values decreases. The shape that this curve forms is like a bell-shaped. So the shape of normal distribution is bell shape.

Hence, the shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

Correlation between Shifts in Moon Cycle and Shifts in Tides

Step-by-step explanation:

Your graph here is a graph of a relation, as most graphs / all functions are. So, you should include what you are comparing (full moons and tide heights).

Your x-axis is already shown to be measured by days, but you might want to include a more direct explanation {if you think that is what is being asked of you here}

possibly: Day of Month

and your y-axis is already shown to be measured in tide height, but you could write:

Answer: x = 5

Step-by-step explanation:

The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.

l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72

Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.

x^2 + 7x - 60 = 0

Apply the quadratic formula

\(\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}\)

We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.

x = 5 and x = -12

An alternate way is just factoring the trinomial to:

(x+12)(x-5) = 0

Johnny Appleseed told me

By using normal distribution, it is obtained that weight of a randomly selected chicken egg is 28.39 grams

What is normal distribution?

Normal distribution is a continuous type probability distribution whose probability density function is

\(\frac{1}{\sigma \sqrt{2\pi}}e^{-\frac{z^2}{2}\)

where,  z = \(\frac{x - \mu}{\sigma}\)

\(\mu\) is the mean and \(\sigma\) is the standard deviation

In case of normal distribution

Formula for z = \(\frac{x - \mu}{\sigma}\)

\(\mu\) is the mean and \(\sigma\) is the standard deviation

Let the weight of the egg be x grams

Here, z = -1.41, \(\mu\) = 58 and \(\sigma\) = 21

\(-1.41 = \frac{x - 58}{21}\\\)

x = -1.41 \(\times\) 21 + 58

x = 28.39 grams

Weight of a randomly selected chicken egg is 28.39 grams
