Answer:

Step-by-step explanation:

If ratios are the same, it is geometric:

  8/4 = 16/8 = ... = 2

If differences are the same, it is arithmetic:

  -4-(-8) = 0 -(-4) = ... = 4

If neither is the case, it is neither:

  3-2 ≠ 5 -3

  3/2 ≠ 5/3

In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)

Step-by-step explanation:

A rectangle is a quadrilateral (four sides) with two pairs of equal opposite and parallel sides. All the four angles in a rectangle are equal to 90° (right angle). The diagonals of a rectangle are equal and bisect each other.

The area of a rectangle = length * breadth

a) Area = length * breadth = 8 cm * 3 cm = 24 cm²

b)  Area = length * breadth = 5.2 cm * 7.7 cm = 40.04 cm²

Answer:

1. H0: σ2 ≤ 0.0008

Ha: σ2 > 0.0008

2. test statistic = 32.625

3. p value = 0.2931

4. D

Step-by-step explanation:

s² = 0.0009

alpha = 0.05

σ² = 0.0008 this is the value that we would be testing

1. hypothesis:

H0: σ2 ≤ 0.0008

Ha: σ2 > 0.0008

2. test statistic:

X² = (n-1/σ²)s²

= ((30-1)/0.0008)0.0009

= 32.625

3. p-value:

P(X² > 32.63) = 0.2931

4. conclusion:

the p-value at 0.2931 is greater than alpha at 0.005, (0.2931>0.05). So the correct option is D. we do not reject H0. the sample does not support conclusion that the population variance specification is being violated.

The Standard form of the number is 44,410.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Here, given number

(3 X 100) + (1 X 110) + (4 X 11000)

(300) + (110) + (44000)

300 + 110 + 44000

410 + 44000

44410

Thus, the Standard form of the number is 44,410.

Answer:

[tex](\dfrac{9}{2}, \dfrac{13}{2})[/tex]

Step-by-step explanation:

The coordinates of A = (2,9)

The coordinates of B = (7,4)

Let M (x,y) be the mid point of A and B.

[tex]M(x,y)=(\dfrac{x_1+x_2}{2}),(\dfrac{y_1+y_2}{2})\\\\=\dfrac{2+7}{2}, \dfrac{9+4}{2}\\\\=(\dfrac{9}{2}, \dfrac{13}{2})[/tex]

So, the coordinates of mid point of A and B is [tex](\dfrac{9}{2}, \dfrac{13}{2})[/tex].

Answer:

B, 5/4s

Step-by-step explanation:

If something increases by 1/4, it means that it is the original number + 1/4 of it.

Ex: x + 1/4x = 5/4x

So if we substitute s for x, the answer must be 5/4s, or B

Answer:

75 adults

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 200 (1)

9x + 18y = 2,475 (2)

From (1)

x = 200 - y

9x + 18y = 2,475

9(200 - y) + 18y = 2,475

1800 - 9y + 18y = 2,475

- 9y + 18y = 2,475 - 1800

9y = 675

y = 675/ 9

y = 75 adults

Substitute y = 75 into (1)

x + y = 200

x + 75 = 200

x = 200 - 75

x = 125 children

The maximum number of adults who could attend if the event fills the venue to capacity is 75

Answer:

You should perform x trials until you observe a success.

Step-by-step explanation:

By process of elimination:

A binomial experiment is a statistical experiment that must meet certain requirements:

Each outcome is either a success (P) or a failure (Q).

All trials are independent.

There are a fixed number of "n" trials.

The probability of success, p, is the same for each trial.

The probability of success, p, is the same for each trial.

You should perform x trials until you observe a success.

We have given that,

There are exactly two possible outcomes success and failure.

We have to determine the following is NOT a common characteristic of a binomial distribution.
