There is no sufficient evidence at the 0.05 level to substantiate the publisher's claim

Note that the significance level, also known as alpha or α, is a measure of the strength of the evidence that must be present in your sample before you will reject the null hypothesis and conclude that the effect is statistically significant

In conclusion, the advertiser failed to reject the null hypotenuse so this would mean there is not sufficient evidence at the 0.02 level of significance to say that the percentage of people who own a Rolls Royce is higher than 47%

The answer to 7 to the power of 2 is 49.

This is because when a number is raised to a power, it means that it is multiplied by itself that number of times. 7 to the power of 2 is 7 multiplied by itself 2 times, which is 7 x 7, which equals 49.

An expression known as "power" denotes the process of repeatedly multiplying a value or integer. An is often a power where n is the exponent and an is the base.

As an illustration, the power 63 demonstrates how three times the number 6 is multiplied.

Answer:

∠ A ≈ 53°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{12}{9}[/tex] , then

∠ A = [tex]tan^{-1}[/tex] ([tex]\frac{12}{9}[/tex] ) ≈ 53° ( to the nearest whole number )

Answer:

2/3

Step-by-step explanation:

Slope = rise / run = 2 / 3

Because points A, B, C, and D are collinear (meaning on the same line), the slope for line segment AB is the same as the slope for segment DC.

Answer:

2/3.

Step-by-step explanation:

The 2 triangles are similar so their corresponding sides are in same ratio.

The sides BA and CD are collinear so theire slopes are the same.

Slope of BA = rise/run = 2/3 so slope of DC is also 2/3.

The explicit formula of the sequence is aₙ = -10 + 8n

From the question, we have the following sequence that can be used in our computation:

The first term and the common difference

These values of the first term and the common difference are given as

First term = -2

Common difference = 8

The interpretation of the above sequence is that the 8 is added to the previous term to get the current term

Using the above as a guide,

So, we have the following representation

aₙ = aₙ₋₁ + 8

When represented explicitly, we have

aₙ = a + (n - 1) * d

Where

a = -2 and d = 8

Substitute the known values in the above equation, so, we have the following representation

aₙ = -2 + (n - 1) * 8

Evaluate the products

aₙ = -2 + 8n - 8

Evaluate the like terms

aₙ = -10 + 8n

Hence, the explicit formula is aₙ = -10 + 8n

26.3

Step-by-step explanation:

Delta Math

The radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

A circle's or sphere's radius is any line segment that connects the object's centre to its perimeter in classical geometry; in more contemporary usage, it is also the length of those line segments.

The word "radius" is derived from the Latin word "radius," which also refers to the spoke of a chariot wheel. Use the equation  [tex]r =\frac{D}{2}[/tex]  to determine the radius, which is equal to half the diameter. This is the same process used to determine a circle's radius from its diameter.

A hemisphere's volume is equal to  [tex]\frac{2}{3} \pi r^3[/tex]  cubic units. Where is an estimated constant with a value of [tex]3.14[/tex]. The hemisphere's radius is denoted by "r."

Required calculations are:

V = r

r = radius.

Given, V = 38153 in³

[tex]38153 = \frac{2}{3} \pi r^3[/tex]

[tex]r^3 = \frac{3 \times 38153}{2 \times \pi }[/tex]

[tex]r = 3\sqrt{\frac{3 \times 38153}{2 \times \pi }}[/tex]

r =26.3 in

Therefore, the radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

Answer:

126.5 cm2

Step-by-step explanation:

First, the equation to find the area of a trapezoid is A= 1/2(b1 + b2)h  , where b1 is the first length and b2 is the second length and h is the height. For these measurements, you would simply factor them into the equation-  A= 1/2(8 + 15)11. Then using pemdas, 8+15= 23... multiplied by 1/2 equalling 11.5. Then multiply 11.5 by 11 to get your answer of 126.5 then add the units.

Pam's piece rate is $16.67 for every pot she produces.

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

Pam's piece rate is the amount of money she earns for each pot she makes. In this case, she earned $250 for making 15 pots, so her piece rate is:

$250 ÷ 15 pots = $16.67 per pot

Therefore, Pam earns $16.67 for each pot she makes. This is a way of calculating her pay based on the number of units she produces, rather than by the hour.

Step-by-step explanation:

Any work inside parentheses must be done first:  (5^2 - 10).  Also:

Exponentiation is done before addition/subtraction:  5^2 - 10 = 25 - 10 = 15

 So now we have 15 / 5 * 2^3 and recognize exponentiation again:

                               15 / 5 * 8

Then, since multiplication and division have the same order of priority,

carry out the division in 15/5 and then multiply the result (3) by 8

Step-by-step explanation:

its is a-5 without absolute value

When the root of x²-bx+c = 0 is decreased by 2, the resulting equation is x²-2x+1, then b = 2 and c = 1

The values of variables satisfying the given quadratic equation are called its roots.

if the roots of a quadratic equation ax²+bx+c = 0 are alpha and beta

alpha + beta = -b/a and

alpha × beta = c/a

when the roots are reduced by 2

alpha-2+ beta-2 = -b/a

(alpha+beta)-4 = -b/a

alpha+ Bata = -b/a + 4

the resulting equation is x²-2x+1 = 0

a = 1, b = -2 and c = 1

therefore alpha +beta = -b/a = -(-2)/1 = 2

therefore 2 = -b/a+4

a = 1

2 = -b+4

b = 4-2 = 2

alpha×beta = c/a = 1/1

(alpha -2)× ( beta -2) = (alpha)( beta) -2(alpha+beta) + 4 = 1-2(2)+4 = 1

therefore b = 2 , c = 1

Step-by-step explanation:

The least common denomiator between 3/5 and 1/20 is 20.

For the first equation, we multiply the numerator and denominator by 4 to get 12/20.

The second equation's denominator is already 1/20, so we can leave it as is.

The final answer is 12/20 and 1/20.

The probability of Anna winning chances of buying 20 ticket out of 1500 tickets is  0.013.

Probability simply means possibility. It deals with how likely something is to happen.

Therefore,

p(A) = number of favorable outcomes to A / total number of outcome

Hence,

Number of ticket bought by Anna = 20

Total ticket sold = 1500

Therefore,

probability of the winning chances of Anna = 20 / 1500

probability of the winning chances of Anna = 2 / 150

probability of the winning chances of Anna = 1 / 75
