Answer:

Result = 124.6

Step-by-step explanation:

If the digit after tenth is greater than or equal to 5, add 1 to tenth. Else remove the digit. Example

124.58

The first number of right of decimal point is 5

The second digit after decimal point is 8 which is greater than 5

So add 1 to 5

Result = 124.6

This is the answer. I hope it helps!

The volume of the given cone is 718.01 square feet. Therefore, option H is the correct answer.

The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane. A cone has a circular base, which means the base is made of a radius and diameter. The volume of a cone formula is 1/3 πr²h.

Given that, radius of a base of cone is 7 feet.

A height of a cone equal to its diameter = 7×2 = 14 feet

Here, volume of a cone = 1/3 ×3.14×7²×14

= 718.01 square feet

Therefore, option H is the correct answer.

Step-by-step explanation:

The domain of this function is n ≥ 1, where n is the round of the tournament.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.

The explicit rule for T(n), the number of games in the nth round of the tournament is 2ⁿ⁻¹. The domain of this function is n ≥ 1, where n is the round of the tournament.

Since all teams play in the first round, the number of games in the first round (n = 1) is 2¹⁻¹, which is equal to 1. As the rounds progress, the number of games in each round is doubled. T

herefore, the number of games in the second round (n = 2) is 2²⁻¹, which is equal to 2. The number of games in the third round (n = 3) is 2³⁻¹, which is equal to 4.

This pattern continues for each round, as the number of games in the nth round is 2ⁿ⁻¹.

Therefore, the domain of this function is n ≥ 1, where n is the round of the tournament.

From the given scatter plot it is a positive trend.

We need to describe the trend of given scatter plots.

A scatter plot shows a positive trend if y tends to increase as x increases. A scatter plot shows a negative trend if y tends to decrease as x increases. A scatter plot shows no trend if there is no obvious pattern.

Here, from the given graph it is a positive trend.

Hence, from the given scatter plot it is a positive trend.

Answer:

The simple interest is 10,150.00 The compound interest is $10,150.56

Step-by-step explanation:

Answer:

A) Alternative hypothesis; Ha: p_o > ⅔

B) Null hypothesis;

H0: p_o = ⅔

C) There is sufficient evidence to support the claim that the community screening programme was effective

D) p-value = 0

Its less than the significance value and so we will reject the null hypothesis and conclude that the community screening programme was effective

Step-by-step explanation:

A) We are told that ⅓ of those diagnosed eventually die of the disease. Thus, ⅔ is the fraction that will survive the disease.

Thus, the null hypothesis is;

H0: p_o = ⅔

We are told that a screening programme was started to increase the survival rate. Thus,the alternative hypothesis is;

Ha: p_o > ⅔

B) null hypothesis is;

H0: p_o = ⅔

C) 164 out of the 200 women selected survived the disease.

Thus sample proportion is;

p^ = 164/200

p^ = 0.82

For the z-score value, we will use the formula;

z = (p^ - p_o)/√((p_o(1 - p_o)/n)

Now, p_o = ⅔ = 0.67

Thus;

z = (0.82 - 0.67)/√((0.67(1 - 0.67)/200)

z = 4.51

From online p-value from z-score calculator, we have p-value ≈ 0

This is less than the significant level of 0.05 and therefore we will reject the null hypothesis and conclude that the community screening program was effective.

D) p-value ≈ 0

Reject the null hypothesis

Step-by-step explanation:

Area = 85ft²

To find the area of the given square you can use the following equation

[tex]Area = Side^2\\Area = 8^2\\Area = 64[/tex]

To find the missing side of the given triangle, you will have to use Pythagorean's theorem

[tex]Short^2 + Long^2 = Hypotenuse^2\\Short^2 + 8^2 = 10^2\\Short^2 + 64 = 100\\Short^2 = 100 - 64\\Short^2 = 36\\Short= \sqrt{36} \\Short= 6 \\[/tex]

Now that we know what both sides are we can use the following equation to get the area of the triangle

[tex]Area = \frac{Side*Side}{2} \\Area = \frac{6*8}{2} \\Area = \frac{42}{2} \\Area = 21 \\[/tex]

After that, we can add both areas together and get the following

[tex]21+64=85[/tex]

Its An experimental study that is a statistical study because it provides the researcher drawing back statistics from the children and its experimental because its based off of an experiment

Option C is correct, an experimental study that is a statistical study.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that a researcher provides 10 children $100 each and another 10 children $20 each. She tracks how they decide to spend the money.

We need to check the statement which best describes the type of study the researcher is doing.
