x = 6/6

x = 1

9x + 2y = 23

Step-by-step explanation:

a). Stock price arranged as arithmetic sequence will be,

   5, 8, 11, 14

b). Since, explicit formula of an arithmetic sequence is given by,

   [tex]a_n=a+(n-1)d[/tex]

   Here, [tex]T_n[/tex] = nth term of the sequence

   a = first term

   n = number of term

   d = common difference

   From the table attached,

   First term of the sequence 'a' = 5

   Common difference 'd' = 8 - 5 = 3

   Therefore, explicit formula for the given sequence will be,

What is the correct answer?​

Answers

I believe the answer is 6, because you can add 6 + 6 to get 13, and I can see that 12 is in the decimal place, along with 30, 3 can be added twice to get 6, and since 30 has 3 in it, and can be added to 6 with 3's, that makes the answer 6.

Sydney is 8 years less than twice Steven’s age what is the algebraic expression.

Answers

Answer:

2s - 8

Step-by-step explanation:

sydney is 8 years LESS than TWICE stevens age.

let’s turn stevens age into a variable... s. the variable will be s. so sydney’s age is 8 years less than TWICE stevens age. so lets start with the twice stevens age..

since there is an easy way to make that part of the equation, let’s just put it as 2s. then we have to take sydney’s age as 8 years less than twice stevens. so that would be - 8. so if you add those 2 parts together, you get the equation 2s - 8.

So overall the proper equation will be 2s - 8.

Adult Great Basin rattlesnakes have a mean length of 32.3 inches and a standard deviation of 5.3 inches; the length of adult Southern Pacific rattlesnakes is also 32.3 inches on average, but with a standard deviation of 7.95 inches. Both species have lengths that follow a normal distribution. You select a random sample of 36 Great Basin rattlesnakes and 100 Southern Pacific rattlesnakes. Which is more likely be shorter than 29.65 inches

Answers

Using the normal distribution and the central limit theorem, it is found that the sample of 36 Great Basin rattlesnakes is more likely to be shorter than 29.65 inches.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For the Sample of 36 Great Basin rattlesnakes:

The mean is [tex]\mu = 32.3[/tex].The standard deviation is [tex]\sigma = 5.3[/tex].Sample of 36, hence [tex]n = 36, s = \frac{5.3}{\sqrt{36}} = 0.88[/tex]We are interested in the percentile of 29.65 inches, hence [tex]X = 29.65[/tex].

Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{29.65 - 32.3}{0.88}[/tex]

[tex]Z = -3.01[/tex]

For the Sample of 100 Southern Pacific rattlesnakes:

The mean is [tex]\mu = 32.3[/tex].The standard deviation is [tex]\sigma = 7.95[/tex].Sample of 100, hence [tex]n = 100, s = \frac{7.95}{\sqrt{100}} = 0.795[/tex]We are interested in the percentile of 29.65 inches, hence [tex]X = 29.65[/tex].

Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{29.65 - 32.2}{0.795}[/tex]

[tex]Z = -3.33[/tex]

Due to the higher z-score, the random sample of 36 Great Basin rattlesnakes is at a higher percentile, hence it is more likely to be shorter than 29.65 inches,

Answers

Answer:

  26.75 square units

Step-by-step explanation:

Above the dashed horizontal line(s) is a triangle with base 9 and height 3.5. Its area is ...

  A = (1/2)bh

  A = (1/2)(9)(3.5) = 15.75 . . . . square units

__

Below the dashed horizontal line(s) is a trapezoid with bases 9 and 2, and height 2. Its area is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(9 +2)(2) = 11 . . . . square units

The sum of these areas is the area of the shape:

  total area = 15.75 +11 = 26.75 . . . . square units

The complete factorization of the given polynomial is 2(x-5)(x+1)(x-1).

The given polynomial is 2x³-10x²-2x+10.

What are factors of polynomial?

The factors are the polynomials which are multiplied to produce the original polynomial.

The factorization of the given polynomial is as follows:

2x³-10x²-2x+10

= 2x²(x-5)-2(x-5)

= (x-5)(2x²-2)

= 2(x-5)(x²-1)

Now, x²-1=(x+1)(x-1) (∵(a²-b²=(a+b)(a-b))

So, 2(x-5)(x+1)(x-1)

Therefore, the complete factorization of the given polynomial is 2(x-5)(x+1)(x-1).
