A spinner is divided into eight equal-sized sections, numbered from 1 to 8, inclusive. What is true about spinning the spinner one time? Select three options. S = {1, 2, 3, 4, 5, 6, 7, 8} If A is a subset of S, A could be {1, 2, 3}. If A is a subset of S, A could be {7, 8, 9}. If a subset A represents spinning a number less than 4,then A = {1, 2, 3, 4}. If a subset A represents the complement of spinning an odd number, then A = {2, 4, 6, 8}.

Answers

Answer: A, B, and E

Step-by-step explanation:

The true statements are (A) A could be {1, 2, 3} and (B) A could be {1, 2, 3, 4}, where A  is a subset of S

How to determine the true statements?

The sample space is given as:

S = {1, 2, 3, 4, 5, 6, 7, 8}

The possible subsets of S are as follows:

Even numbers = {2,4,6,8}Odd numbers = {1,3,5,7}Any number or group from 1 to 8, inclusive

Using the above highlights, the possible set of A are:

A could be {1, 2, 3}. A = {1, 2, 3, 4}.

Hence, the true statements are (A) and (B)

Answers

Answer:

30.6

Step-by-step explanation:

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The length of the side j is 30.6 cm.

What is Sine rule?

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]

where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,

Sin B is the angle and β is the length of the side of the triangle opposite to angle B,

Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

Given the length of i is 53 cm, while the measure of the ∠I is 120°. Also, the measure of ∠J is 30°. Therefore, the length of the side j is,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}\\\\\dfrac{Sin\ I}{i} =\dfrac{Sin\ J}{j} \\\\\dfrac{Sin\ 120^o}{53} =\dfrac{Sin\ 30^o}{j} \\\\j = \dfrac{Sin\ 30^o \times 53}{Sin\ 120^o}\\\\j = 30.5995 \approx 30.6\rm\ cm[/tex]

Hence, the length of the side j is 30.6 cm.

Two larger cubes are made out of unit cubes. Cube A is 2 by 2 by 2. Cube B is 4 by 4 by 4. The side length of Cube B is twice that of Cube A.

Is the volume of Cube B also twice that of Cube A? Explain or show your

Answers

The side length of Cube B is twice that of Cube A.

The surface area of Cube B is not twice that of Cube A.

The volume of Cube B is not twice that of Cube A.

What is the surface area of a cube?

The surface area of a cube is the total of all of its covered faces. Six times the square of the cube's side length is the formula for surface area.

Here, we have

Given: Two larger cubes are made out of unit cubes. Cube A is 2 by 2 by 2. Cube B is 4 by 4 by 4. The side length of Cube B is twice that of Cube A.

Cube A is 2×2×2.

Cube B is 4×4×4.

The side length of Cube A is 2 and the side length of Cube B is 4. So, the side length of Cube B is twice that of Cube A.

The surface area of a cube is

Area = 6(side)²

Using this formula we get

Area of cube A = 6(2)² = 24

Area of cube B = 6(4)² = 96

96 is 4 times 24.

Hence, the surface area of Cube B is not twice that of Cube A.

The volume of a cube is

Volume = (side)³

Using this formula we get

The volume of cube A = (2)³ = 8

The volume of cube B =  (4)³ = 64

64 is 8 times 8.

Hence, the volume of Cube B is not twice that of Cube A.

x + 3y = 13
- 3x + 2y = 27 steps on how to solve by substitution

Answers

here x+3y=13

x=13-3y.....1st equation

-3x+2y=27......2nd euation

now putting the value of x from equation 1st in 2nd we will get

-3(13-3y)+2y=27

-49+9y+2y=27

11y=27+49

y=76÷11

y=6.9

now again putting the value of y in equation 1st we get

x=13-3×6.9

x=13-20.7

x=7.7

C)

x = 5 if x2 = 25

D)

Answers

It is D

I just took the test and got it right

The biconditional statement is x = 5 if and only if x + 5 = 10.

Option D is the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Biconditional statement.

This means,

The statement and its converse are both true.

Now,

x = 5 if and only if x + 5 = 10

This shows that both the statement and its converse are true.


Thus,

x = 5 if and only if x + 5 = 10 is a biconditional statement.

Consider random samples of size 900 from a population with proportion 0.65 . Find the standard error of the distribution of sample proportions.

Answers

Answer:

The value is [tex]\sigma_{p} = 0.022[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  900

    The population proportion is  [tex]p = 0.65[/tex]

Generally the standard error of the distribution of sample proportion is mathematically represented as

       [tex]\sigma_{p} = \sqrt{\frac{ p(1 - p)}{ n} }[/tex]

=>     [tex]\sigma_{p} = \sqrt{\frac{ 0.65 (1 - 0.65 )}{ 900} }[/tex]

=>     [tex]\sigma_{p} = 0.022[/tex]
