Answer:

The statement that gives the best conclusion that should be made based on the results and provides the best explanation for the conclusion is option D;

D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores

Step-by-step explanation:

The data given in the question are presented as follows;

The particulars the CD manufacturer wants to determine = The CD cover design that will generate more sales

The mode of selection of the stores for the test = Random selection

The number of stores in each group of stores, n = 35 stores

The number of sets of stores tested = 2 sets of stores

Let [tex]\overline x_1[/tex] represent the mean number CDs sold at one set of stores and [tex]\overline x_2[/tex] represent the mean number CDs sold at the other set of stores

The null hypothesis, H₀; [tex]\overline x_1[/tex] = [tex]\overline x_2[/tex]

The alternative hypothesis, H₀; [tex]\overline x_1[/tex] ≠ [tex]\overline x_2[/tex]

Given that the statistical analysis shows that the difference in mean between the two sets of randomly selected stores is significant, we therefore should reject the null hypothesis and accept the alternative hypothesis that there is a significant difference in CD sale attributable to the difference in cover design as the CDs having on of two cover design where assigned randomly to the stores.

Answer:

Probability of rolling number 3 = [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Lin has a die with 6 sides.

Each side of the die is labeled with 1, 2, 3, 4, 5 and 6.

Since, probability of rolling any number = [tex]\frac{\text{Favorable event}}{\text{Total number of events}}[/tex]

Therefore, probability of rolling number 3 = [tex]\frac{\text{Favorable event}}{\text{Total number of events}}[/tex]

Favorable event of getting 3 in single roll = 1

Total events that can happen in one roll = 6

Therefore, probability of rolling number 3 = [tex]\frac{1}{6}[/tex]

Answer:

the answer is 2x²-10x+8

The trinomial equation is A = 2x² - 10x + 8

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( x - 1 ) ( 2x - 8 )   be equation (1)

On simplifying the equation , we get

A = x ( 2x - 8 ) - 1 ( 2x - 8 )

A = x ( 2x ) - x ( 8 ) - 2x + 8

On further simplification , we get

A = 2x² - 8x - 2x + 8

A = 2x² - 10x + 8

Therefore , the value of A is 2x² - 10x + 8

Hence , the equation is A = 2x² - 10x + 8

[tex]\frac{1}{2}[/tex] or 0.5 or 50%

Step-by-step explanation:

P(not even) = P(odd) = P(1) or P(3) or P(5) = P(1) + P(3) + P(5)

Answer: 7.71%

Step-by-step explanation:

Number of students in a school last year = 700

Number of students in a school this year = 646

Reduction in the number of students = 700 - 646 = 54

The percentage reduction will be:

= Reduction in number / Last year students × 100

= (54 / 700) × 100

= 7.71%

A: Measure of center, also known as the Median.

Answer:

The circumference of a circle =πd = π×18 =18π m

The diameter of a circle is 18 m. Find its circumference in terms of π.

Diameter of a circle = 18 m. (Given)

Radius (r) of a circle = 18/2 = 9 m.

We know,

[tex] \dag [/tex] Circumference of a circle is 2πr.

So, It's circumference is (2 × π × 9) m.

It's circumference is 18π m.

Answer:

g(-1)=4 ,f(g(-1))=18

Step-by-step explanation:

g(-1):

1-3(-1)=4

f(g(-1)):

sub in g(-1) as x

(4)^2+2=18

2x - 1 < 10

Add 1 to both sides:

2x < 11

Divide both sides by 2:

x < 5.5

Answers must be smaller than 5.5, therefore option (D) is the answer.

Step-by-step explanation:

∠[tex]YZU=10*15+9=159[/tex]

[tex]---------[/tex]

hope it helps...

have a great day!!

Answer:

159°

Step-by-step explanation:

A circle measures 360°. We can use this knowledge to find the unknown angles.

(10x + 9) + (6x - 13) + 34 + 90 = 360

Combine like terms and solve for x.

16x + 120 = 360

16x = 240

x = 15

So, we have found the value of x, and can now find m∠YZU.

10(15) + 9 = m∠YZU

m∠YZU = 159°

We can ascertain that this is the answer by plugging in x for the initial equation we created.

(10(15) + 9) + (6(15) - 13) + 34 + 90 = 360

159 + 77 + 34 + 90 = 360 It works!

2. $2764.80

3. 84 in^2

4. 6 inches

Step-by-step explanation:

1. Area of a triangle is base x height x 1/2

2. Multiply the area by the amount: A = 768 so 768 x 3.60 = total cost

3. Area of a trapezoid is (base x height) x height / 2

4. Area of triangle is base x height x 1/2 so if you multiply the area by 2 and divide by 18, you can find the base, which is 6

The measure of the unknown angle is 70 degrees

In circle geometry, there is a theorem that states that the angle at the centre of a circle is twice the angle at the circumference

Given the following parameters;

Angle at the circumference = x

Angle at the centre = 140 degrees

Using the given theorem;

140 = 2x

Swap

2x = 140

x = 140/2

x = 70

Hence the measure of the unknown angle is 70 degrees
