Answer:

Volume = 240 feet³

Step-by-step explanation:

We'll find it's volume

Volume = [tex]Lenth *Width*Height[/tex]

Where Length = 4, Width = 6, Height = 10

Volume = 4 * 6 * 10

Volume = 240 feet³

Answer:

nonlinear

Step-by-step explanation:

The word 'linear' means something having to do with a line. On a Cartesian Plane, a linear characteristic is a feature wherein the graph is a straight line. The line can cross in any direction, but it's always an instant line. A non-linear function has a shape that isn't an immediate line

The graph is nonlinear because it is not a straight line.

Answer:

Nonlinear.

Step-by-step explanation:

Since x is being squared, the equation is actually a parabola. The power of x has to be 1 for the function to be a linear function, so this equation is nonlinear.

Answer:c. F(2)=g(-2)

Step-by-step explanation:

Answer:

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Step-by-step explanation:

Let A denote Annie and X denotes Xenas.

The total time is 2 hours (2:00 to 4:00)

Both A and X stays for 45 minutes or 3/4 hours

The probability that A and X do not meet is given by

P(Not meet) = (3/4)/2 × (3/4)/2

P(Not meet) = 9/64

So the probability that A and X will meet is given by

P(meet) = 1 - P(Not meet)

P(meet) = 1 - 9/64

P(meet) = 55/64

P(meet) = 0.8594

P(meet) = 85.94%

Therefore, there is a 85.94% probability that Annie and Xenas see each other at the party.

Answer: The height is 6 meters

Step-by-step explanation:

3 * 2 *h = 36   where h is the height

6h = 36

h = 6

Answer:

The answer is 6

Step-by-step explanation:

Because you would have to get 6h=36 alone so you would have to divide 6 by both sides. which gives you h=6

You can use

cos(theta) = u · v / ║u║║v║

that will come out to:

u = 2 x (-4) = -8

v = 3 x (-8) = - 24

u · v = -16

║u║ = [tex]\sqrt{(2)^{2} + (-4)^{2} }[/tex]  = [tex]\sqrt{20} = 2\sqrt{5}[/tex]

║v║ = [tex]\sqrt{(3)^{2} + (-8)^{2} } = \sqrt{73}[/tex]

cos(theta)  = -16/2 [tex]\sqrt{365}[/tex]

and to find (theta), you can now do

theta = (cos^-1) ( -16/2 [tex]\sqrt{365}[/tex])

I don't have a calculator, but you can solve that final problem to find theta

Answer:

f(x) = |x + 4| + 2.

Step-by-step explanation:

When you shift the function to the left, the x-value changes, so you put the change within the absolute value. Also, within the absolute value, when you shift things to the right, you minus, and when you shift to the left, you add.

When you shift the function up, the y-value changes, so you put the changes outside of the absolute value. Shifting up means adding and shifting down means subtracting.

Answer:

0.75 or 3/4

Step-by-step explanation:

If we call the common ratio r, since 4 - 1 = 3 we can write:

64 * r³ = 27

r³ = 27/64

r = ∛(27/64) = ∛27 / ∛64 = 3 / 4

Answer:

(a) the common ratio = 3/4.

Step-by-step explanation:

First term a1 = 64

The fourth term a4 = a1 r^3 = 27

So a1 r^3 / a1 = 27/64

r^3 =  (27/64)

r = ∛ (27/64

= 3/4.

The exterior angle of a triangle is sum of two opposite interior angles.

m<A+m<B=m<5x+13

[tex]or \: 2x - 9 + 4x + 2 = 5x +13 \\ or \: 2x + 4x - 9 + 2 = 5x + 13 \\ or \: 6x - 7 = 5x + 13 \\ or \: 6x - 5x = 13 + 7 \\ x = 20[/tex]

1. The percentage of the players who finished the walk in less than 2 hours  will be  2.28%

2. The probability that two randomly chosen players completed the walk in 2.9 hours or more was 15.87%

3. The probability that four randomly chosen players completed the walk was between 1.7 and 2.9 hours  84%

4. The number of participants who complete the walk in more than 3.5 hours, given that there are 1,200 participants 0

5. if the number of participants increased, the probability would increase while if they decreased, the probability would decrease

The z score is a measure used in probability to determine the number of standard deviations the raw score is above or below the mean, it is given by the equation:

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

Given that:

the mean μ = 2.6 hours and a standard deviation(σ) of 0.3 hours.

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

1) What percent of the players finished the walk in less than 2 hours.

To calculate this, we use x as 2 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2-2.6}{0.3}=-2[/tex]

From the normal probability distribution table, P(x < 2) = P(z < -2) = 0.0228 = 2.28%

2)  What is the probability that two randomly chosen players completed the walk in 2.9 hours or more

To calculate this, we use x as 2.9 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2.9-2.6}{0.3}=1[/tex]

From the normal probability distribution table, P(x > 2.9) = P(z > 1) = 1-P(z<1) = 1 - 0.8413 = 0.1587

3. What is the probability that four randomly chosen players completed the walk between 1.7 and 2.9 hours

To calculate this, we first use x as 1.7 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{1.7-2.6}{0.3}=-3[/tex]

For x as 2.9 hours and then find the z score.

[tex]Z=\dfrac{x-\mu}{\sigma}=\dfrac{2.9-2.6}{0.3}=1[/tex]

From the normal probability distribution table, P(1.7 < x < 2.9) = P(-3 < z < 1) = P(z<1) - P(z < -3) = 0.8413 - 0.0013 = 0.84

4. What observations can you make about the number of participants who complete the walk in more than 3.5 hours, given that there are 1,200 participants?

To calculate this, we use x as 3.5 hours, a number of samples (n) = 1200, and then find the z score.

[tex]Z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}=\dfrac{3.5-2.6}{\dfrac{0.3}{\sqrt{1200}}}=104[/tex]

From the normal probability distribution table, P(x > 3.5) = P(z > 104) = 1-P(z<104) = 1 - 1 = 0

5. What might you observe if the number of participants increased or decreased?

if the number of participants increased, the probability would increase while if they decreased, the probability would decrease

Answer:

The measurement for x is 80°

Step-by-step explanation:

In the picture, we see two parallel lines cut by a transversal line. Since the lines are cut by a transversal, then there are a few things we should know that can help us find the value of x.

Now that we know these things, we can use this information to find the measurement of ∠CBA. We do this by subtracting 100 from 180 because ∠CBA and ∠CBD are a linear pair. Once we know the measurement of this angle, then it will be much easier to find the value of x.

180 - 100 = 80

So, the measurement of ∠CBA is 80°. Now, ∠CBA and ∠x are corresponding angles so this means that they have the same measurements. If the measurement of ∠CBA is 80°, then the measurement of ∠x is also 80°

x = 80°

Answer:

These are squares of numbers 8 to 4.

Step-by-step explanation:

The given sequence of numbers is given as:

64, 49, 36, 25, 16

First of all let us factorize each number:

[tex]64 = 8 \times 8\\49 = 7 \times 7\\36 = 6 \times 6\\25 = 5\times 5\\16 = 4\times 4\\[/tex]

We can see that every number is obtained by multiplying some other number by itself.

For example, 64 is obtained by multiplying 8 with itself i.e. 8 multiplied with 8.

49 is obtained by multiplying 7 with itself i.e. 7 multiplied with 7.

and so on.

So, each number is a square of some number.

The numbers are in decreasing order. (64 to 16)

i.e. we have square of numbers here.  

Square of 8, square of 7, square of 6, square of 5, square of 4,

Generalizing the terms:

[tex]a_n = (9-n)^2[/tex] where n is from 1 to 5

The name given to the sequence is:

Square of (9-n) where n is from 1 to 5.

OR

square of numbers, numbers from 8 to 4 in decreasing order.

Answer:

y - 1 = 0.

Step-by-step explanation:

First off, we need to find the slope between the two points. That would be (1 - 1) / (2 - -2) = 0 / 4 = 0.

So, we would have an equation y = mx + b, where m is the slope and b is the y-intercept. Since the slope is 0, we have y = 0x + b, or y = b.

If you examine the coordinates, y always equals 1. So, b = 1, and y = 1.

y = 1

y - 1 = 0.
