Answer 1

Answer:

See explanation

Step-by-step explanation:

1)

The importance of the inequality is that this it restricts the possible values of the change.

2)

Without the inequality, q would not be restricted at all, and would be free to range in all values.

what is the GCM of 9 and 7

Answers

Answer: See explanation

Step-by-step explanation:

Do you mean the greatest common factor (GCF), or the lowest common multiple (LCM).

If you mean GCF, then it is 1 because 7 is a prime number and has two facotrs (1 and itself) and since 9 isn’t divisible by 7, the GCF must be 1.

If you mean the LCM, the answer is 63. Using prime factorisation, we find the lowest prime factor of both numbers:

9 = 3^3

7= 7^1

Then, we multiply these together to give 63.

You cannot have a GCM, because you can’t find a greatest common multiple as numbers go on forever.

Step-by-step explanation:

hi! for this problem, all we need is the equation for the SA for a cylinder!

here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]

BUT FIRST let's identify our given numbers

the radius, or r, is 4 (r = 4) the height, or h, is 10 (h = 10)

now all we have to do is plug in what is given to the equation above! not so bad, right?

plugged in equation

[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]

- now let's simplify!

[tex]2\pi (40) + 2\pi (16)[/tex]

Answer:

First number line: 3rd line from 0

Second number line: 7th line from 0

(Sorry if I explained it kinda weird, hope this helps!)

Step-by-step explanation:

On the first number line, you would put the dot on the 3rd line from zero. From 0 to one, it's split into 5 equal parts. 0 is 0/5 and 1 is 5/5. So all you do is  plot the dot on 3/5, or the 3rd line from 0.

Same thing with the second number line. Except for this time, it's split into 8 equal parts. Just count to the 7th line in between 0 and 1 and plot the dot.

Triangle ABC is shown. What value of x will prove that Triangle ABC is a right triangle?

Answers

In the given triangle ABC in the figure, the value obtained for x will be equal to 6.

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

Use the equation of Pythagoras' theorem,

h² = p² + b²

(2x - 2)² = x² + (x - 2)²

4x² - 2(2x)(2) + 4 = x² + x² + 4 + 4x

4x² - 8x + 4 = 2x² + 4x + 4

4x² - 2x² - 8x - 4x + 4 - 4 = 0

2x² - 12x = 0

2x² - 12x = 0

2x(x - 6) = 0

So,

2x = 0

⇒ x = 0, it is not possible.

Or,

x - 6 = 0

x = 6

Can someone please help me solve for x

Answers

Answer:

x = 8

Step-by-step explanation:

These two angles both containing an x are equal. They are called vertically opposite angles.

2x + 62 = 5x + 38               Subtract 2x from both sides

2x-2x + 62 = 5x -2x + 38   Combine

62 = 3x + 38                       Subtract 38 from both sides

62 - 38 = 3x - 38  + 38       Combine

24 = 3x                                Divide both sides by 3

24/3 = 3x/3                         Combine

8 = x

A market research firm is studying the effects of price and type of packaging on sales of a particular product. Twenty-seven stores with shoppers of similar characteristics will be used in the study. The nine combinations of three price levels and three packaging types are the treatments of interest. Total sales of the product over a seven-week period will be recorded. Which of the following describes the best design to use for the study?

a. А A completely randomized design Randomly assign the nine combinations of price level and packaging type that three stores use each combination
b. A completely randomized design. Randomly assign the three price levels so that nine stores use each price level
c. A completely randomized design. Randomly assign the three packaging types so that nine stores use each type of packaging
d. A randomized block design Use packaging as a block. Randomly assign the nine combinations of three price levels and three packaging types so that three stores use each combination
e. A randomized block design. Use packaging as a block Randomly assign nine stores to each packaging type, then randomly assign price level to three stores within each block.

Answers

The market research can increase the precision of the result of the study by  

using a randomized block design RBD

The best design the market research company should use for the study is

d. A randomized block design Use packaging as a block. Randomly assign

the nine combinations of three price levels and three packaging types so

that three stores use each combination

Reason:

The given parameters are;

The study = The effect of price and type of packaging

Number of stores in the study = 27 stores

Characteristics of the shoppers in the stores = Similar

Number of packaging type = 3 (three)

Number of price levels = 3 (three)

The number of pair combinations = ⁶₂C - (3, pairs of the same packaging +

3, pairs of the same prices) = 9

Required:

The best design to use for the study

Solution:

Given that the shoppers at each store are similar, in order to differentiate

and show the effect of the price and package combination, it is possible to

group the treatment into groups having a particular characteristics, while

ensuring that the other available treatments are assigned to each member

within a group at least once.

The above design of the study is known as a randomized block design,

therefore;

The correct option is d. A randomized block design Use packaging as a

block. Randomly assign the nine combinations of three price levels and

three packaging types so that three stores use each combinations.

Given the endpoints D(-2, 3) and L(4,1)
Find the midpoint of DL.

Answers

Answer:

Midpoint = (1,2)

Step-by-step explanation:

Using coordinates: D(-2,3) and L(4,1)

Using the midpoint formula:

Midpoint of DL = (D1 + L1) / 2, (D2 + L2) / 2

Midpoint of DL = (-2 + 4) / 2, (3 + 1) / 2

Midpoint of DL = (2) / 2, (4) / 2

Therefore the midpoint of DL is (1,2)
