The required sample size is 694.

Given a student wants to make a guess within 0.03 of the true ratio with a 95% confidence level.

Margin of Error, E = 0.03

significance level α=0.05  {95% confidence}

A given estimate of the percentage of population p is p = 0.79.

The critical value for the significance level α = 0.05 is Zc = 1.96. This can be determined using either Excel or a normal probability table.

Use the following formula to calculate the minimum sample size required to estimate the percentage of population p within the required margin of error.

n≥p(1-p)(Zc÷E)²

n=0.796×(1-0.796)(1.96÷0.03)²

n=693.1016

Therefore, the  resample sizequired to meet the condition is n ≥ 693.1016 and must be an integer. From this, we conclude that the minimum sample size required is n = 694.

Answer:

n=-20

Step-by-step explanation:

The correct answer is (D) The Confidence interval is between 71% and 77%.

The margin of error in a study represents the amount of error that is acceptable in the results due to the sample size and the variability of the data. It is an estimate of how much the sample proportion may differ from the true population proportion.

In this study, the margin of error is 3.2%, which means that the true proportion of patients experiencing flulike symptoms in northern California during December could be as much as 3.2% higher or lower than the sample proportion of 74%.

To determine the confidence interval for the study, we can use the formula:

Confidence Interval = Sample Proportion ± Margin of Error

Plugging in the values, we get:

Confidence Interval = 0.74 ± 0.032

Simplifying, we get:

Confidence Interval = (0.708, 0.772)

Therefore, the correct answer is (D) The confidence interval is between 71% and 77%.

Anyways, grouping up "6+12" as one group and "2^2-2+1" as the other leads to

\((6+12) \div (2^2-2+1) = 18 \div 3 = 6\)

-----------------------------

For the next problem, you'll need 2 sets of parenthesis, but this time one set of parenthesis is inside another one. The (6+12) becomes 18, which divides by 2 to get 9. Squaring that leads to 81 and then you subtract off 1 to get 80.

\(( (6+12) \div 2)^2 - 2 + 1 = (18\div 2)^2 - 1 = 9^2-1 = 81-1 = 80\)

Answer:

10+5v=70

Step-by-step explanation:

this is because you need to consider the outright monthly cost of $10 first. then you don't know how many visits you'll need so you have to fill in v and multiply it by the cost per visit. and it must equal 70 so that it is equal to the other membership.

The equation 70 = 10 + 5v is used to determine the number of visits per month needed for two membership types to cost the same. Solving the equation would provide that 12 visits a month will make both memberships cost the same.

The subject of this question is Mathematics, and it is related to the topic of linear equations. Given the problem, we know that there are two types of membership options:

Here, Y represents the total cost of the membership each month and v represents the number of visits to the water park per month. You can set these two equations equal to each other in order to find the number of visits (v) needed for the two membership types to cost the same amount:

70 = 10 + 5v

You solve the equation for v to get: v = (70 - 10) / 5 = 12

Therefore, it would take 12 visits per month for both memberships to cost the same.

The correct statement is: the volume of the cylinder is 8 cubic inches more than that of the cone.

The volume of cone (V) = 1/3 * πr²h

Volume of cylinder (V) = πr²h

Where, r is the radius of their bases.

The base area formula for the cone = πr²

Calculate the area of the base of the cone that has a radius (r) of 2.5 in:

Area of the base of the cone = π(2.5)² ≈ 19.6

The volume of the cone (V) = 1/3 * πr²h = 1/3 * π * 2.5² * 6.5

≈ 42.5 cubic inches

Volume of cylinder (V) = πr²h = π * 2² * 4

≈ 50.3 cubic inches

The difference in volume = 50.3  - 42.5

= 7.8 ≈ 8 cubic inches

Therefore, the only statement that is true is: the volume of the cylinder is 8 cubic inches more than that of the cone.

The statement is true. Roofs with a span of 40 feet or less and a pitch of ? or greater, as well as roofs with a span of more than 40 feet and a pitch of 1/4 or greater, are considered to be pitched.

In roofing terminology, the pitch refers to the steepness or slope of a roof. A pitched roof has a slope that allows water to drain efficiently. The pitch is typically measured as a ratio of vertical rise to horizontal span.

According to the statement, roofs with a span of 40 feet or less and a pitch of ? (undefined or not specified) or greater are considered to be pitched. This means that as long as the roof has a certain degree of slope or steepness, it is categorized as a pitched roof.

Similarly, roofs with a span of more than 40 feet and a pitch of 1/4 or greater are also considered to be pitched. In this case, the requirement for a minimum pitch of 1/4 (or a steeper slope) applies to roofs with a larger span.

The classification of roofs as pitched or not pitched depends on their span and the minimum pitch requirements specified. Roofs that meet the specified criteria for span and pitch are considered to be pitched roofs.

The equation of the tangent line to f(x) at the point (4, -43/4) is 4y = -17x + 25.

To find the equation of the tangent line to the function f(x) = -4x^(1/2) + x^(-1) - 3 at the point (4, -43/4), we can use the point-slope form of a line.

First, let's find the derivative of f(x) to obtain the slope of the tangent line at any point on the curve:

f(x) = -4x^(1/2) + x^(-1) - 3

f'(x) = (-4)(1/2)x^(-1/2) + (-1)(x^(-2))

= -2x^(-1/2) - x^(-2)

= -2/sqrt(x) - 1/x^2

Now we can find the slope of the tangent line at x = 4 by evaluating f'(4):

f'(4) = -2/sqrt(4) - 1/4^2

= -2/2 - 1/16

= -1 - 1/16

= -17/16

So the slope of the tangent line at the point (4, -43/4) is -17/16.

Now we can use the point-slope form of a line to find the equation of the tangent line:

y - y₁ = m(x - x₁)

Where (x₁, y₁) is the given point (4, -43/4) and m is the slope (-17/16).

Substituting the values into the equation:

y - (-43/4) = (-17/16)(x - 4)

Simplifying:

y + 43/4 = (-17/16)(x - 4)

Multiplying both sides by 4 to eliminate fractions:

4y + 43 = -17(x - 4)

Expanding and rearranging:

4y + 43 = -17x + 68

4y = -17x + 25

The equation of the tangent line to f(x) at the point (4, -43/4) is 4y = -17x + 25.

There are infinitely many solutions to this problem.

Step-by-step explanation:

Let B denotes broccoli crop

Let S denotes spinach crop

Last year, he grew 6 tons of broccoli per acre and 9 tons of spinach per acre, for a total of 93 tons of vegetables.

Mathematically,

6B + 9S = 93        eq. 1

This year, he grew 2 tons of broccoli per acre and 3 tons of spinach per acre, for a total of 31 tons of vegetables.

Mathematically,

2B + 3S = 31

2B = 31 -  3S

B = (31 -  3S)/2      eq. 2

Substitute eq. 2 into eq. 1

6B + 9S = 93

6[(31 -  3S)/2] + 9S = 93

3(31 -  3S) + 9S = 93

93 - 9S + 9S = 93

- 9S + 9S = 93 - 93

0 = 0

Therefore, there is no unique solution to this problem.

Which means that there are infinitely many solutions to this problem.

The given function f, with the provided set of ordered pairs, has a domain of {10, 17, 45, 51} and a range of {-6, 1, 5}.

The domain of a function refers to the set of all possible input values or x-values for which the function is defined. In this case, the given set of ordered pairs determines the domain. Looking at the x-values in the set {10, 17, 45, 51}, these are the unique inputs for which the function f is defined. Hence, the domain of f is {10, 17, 45, 51}.
On the other hand, the range of a function refers to the set of all possible output values or y-values that the function can take. By examining the y-values in the set {-6, 1, 5}, we can observe the distinct outputs generated by the function f. Thus, the range of f is {-6, 1, 5}.

The required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.

The radius of the sphere is denoted by the letter r, and the specified point represents its center.

The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin.

A sphere is a solid shape that is circular, without borders.

Balloons, toy balls, and even light bulbs are examples of objects with sphere shapes.

So, the volume of the sphere formula is:
