what is (c+d) to the power of 3​

Answers

Answer:

c³ + cd³ + 3c²d + 3cd²

Step-by-step explanation:

(c+d)^3 is worded as c plus d quantity cubed which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.

(c+d)(c+d)(c+d)

You can only multiply 2 at a time so do the first two then the result and the third one.

Distribute everything in one quantity to the other so c*c = c^2 and c*d = cd

= (c^2 + 2cd + d^2)(c+d)

= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3

Combine like terms

= c³ + 3c²d + 3cd² + cd³

The proportion of values of X between -3 and 8, if ∼(5,4.2)
X

N
(
5
,
4.2
)
. Round your answer to three decimal places.

Answers

If I'm understanding the question correctly, you're saying that X is a random variable following a normal distribution with mean 5 and standard deviation 4.2, and you want to find the proportion of the distribution that lies in the interval (-3, 8). In other words, the probability

P(-3 < X < 8)

Transform X to Z, which follows the standard normal distribution with mean 0 and standard deviation 1, using the rule

X = µ + σZ   ==>   Z = (X - µ)/σ

where µ and σ are the mean and standard devation of X, respectively.

We have

P(-3 < X < 8) = P((-3 - 5)/4.2 < (X - 5)/4.2 < (8 - 5)/4.2)

… ≈ P(-1.904 < Z < 0.714)

… ≈ P(Z < 0.714) - P(Z < -1.904)

… ≈ 0.762 - 0.028 ≈ 0.734

The proportion of values of X between - 3 and 5 is 0.734

The expression ∼(5,4.2) gives the mean and standard deviation of X

Mean, μ = 5

Mean, μ = 5Standard deviation, σ = 4.2

Using the normal distribution :

The proportion of values of X is given as :

z = (x - μ) / σ

P(Z < z) - P(Z < z)

P(Z < (x - μ) / σ) - P(Z < (x - μ) / σ)

For X = - 3 and x = 8

P(Z < (8 - 5) / 4.2) - P(Z < (-3 - 5) / 4.2)

P(Z < 0.7143) - P(Z < - 1.90476)

0.76248 - 0.0284 = 0.73408

Hence, the proportion of values of X between - 3 and 5 is 0.734

What is the image point of (-8,9)(−8,9) after a translation right 3 units and down 1 unit?

Answers

Answer:

(-5,8)

Step-by-step explanation:

The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.

Answer:

the answer is the same since it is the same numeral so in terms of y=mx+c and x1/y1 would be inversely proportional to x2/y2 which is perfectly direct proportional to x3/y3×2 and then dy over dx is the problem of integration so you use (x2/x3÷y2/y3)×x1^y1

What is the value of y in the sequence below?
2,y,18, -54,162,

Answers

First, let's check if the sequence is geometric or arithmetric.

If arithmetric, the sequence will have common difference.

Arithmetric

[tex] \displaystyle \large{a_{n + 1} - a_n = d}[/tex]

d stands for a common difference. Common Difference means that sequences must have same difference after subtracting.

Geometric

[tex] \displaystyle \large{ \frac{a_{n + 1}}{a_n} = r}[/tex]

r stands for a common ratio.

To find the value of y, you can check the sequence. If we try subtracting the sequences, the differences are different. That means the sequences are not arithmetric. That only leaves the geometric sequence.

Let's check by dividing sequences.

We have:

2,y,18,-54,162,...

Let's check by divide -54 by 18 and 162 by -54. We need to divide more than one so we can prove that the sequence is geometric.

[tex] \displaystyle \large{ \frac{ - 54}{18} = - 3 } \\ \displaystyle \large{ \frac{ 162}{ - 54} = - 3} [/tex]

Hence, the sequence is geometric.

Because the common ratio is -3. Let these be the following:

[tex] \displaystyle \large{ a_{n + 1} = y } \\ \displaystyle \large{ a_n = 2 } \\ \displaystyle \large{ r = - 3 }[/tex]

From the:

[tex] \displaystyle \large{ \frac{a_{n + 1}}{a_n} = r}[/tex]

Substitute the values in.

[tex] \displaystyle \large{ \frac{y}{2} = - 3}[/tex]

Multiply the whole equation by 2 to isolate y.

[tex] \displaystyle \large{ \frac{y}{2} \times 2 = - 3 \times 2} \\ \displaystyle \large{ y = - 6}[/tex]

Therefore, the value of y is -6.

Find the circumference
and area of a circle with
a diameter of 12cm..
Use T = 3.14. Round to
the nearest whole
number.

Answers

Answer:

38cm is the circumference

Explanation:

circumference = diameter x 3.14

diameter = 12

circumference = 3.14 x 12 = 37.68

Now we need to round to the nearest whole

36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.

37.68 - 36 = 0.68

38 - 37.68 = 0.32

37.68 is more closer so we can round this to 38.

What happens to the mean and standard deviation of the data set when the 7 is changed to a 70?

Your answer:

Answers

The mean is  4 because it is in the middle an it is used the most in the data set.

The mean shift to the right side of the data set and the standard deviation is increased.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

It is given that:

The data set is:

1 2 3 3 4 4 4 4 5 5 6 7

The mean of the data = ∑x/n

The mean of the data = 4

The standard deviation of the data set = 1.58

If data changed:

1 2 3 3 4 4 4 4 5 5 6 70

The mean of the data = 9.25

The standard deviation of the data set = 18.36

Thus, the mean shift to right side of the data set and the standard deviation is increased.

Answers

The amount that Aaliyah would have to pay in a month where she used 5 GB over the limit is $195.

Cost of data plan per month = $45

Extra amount charged = $30 per GB

The amount that Aaliyah would have to pay in a month where she used 5 GB over the limit will be:

= $45 + $30(5)

= $45 + $150

= $195

The amount that Aaliyah have to pay in a month where she used went over by x GB will be:

= $45 + $30(x)

= $45 + $30x
