A) Population
B) Sample
C) Statistics
D) Inference
E) Parameter

Answers

Answer 1

Answer:

In basic terms, a population is the total number of individuals, animals, items, observation, data, etc. So the sample, in other words, is a portion, part, or fraction of the whole group, and acts as a subset of the population. Samples are used in a variety of settings where research is conducted.

Answer 2
I think the answer is B because it is impractical to survey every member of a population

There are 8 green, 10 purple, 6 red and 16 blue markers in a box. A marker is chosen,replaced and then another marker is chosen. Find the probability that neither marker is red.

Answers

Final answer:

The probability that neither marker chosen from the box is red is 72.25%

Explanation:

The probability that neither marker chosen is red can be calculated by finding the probability of not picking a red marker twice. There are a total of 40 markers (8 green, 10 purple, 6 red, and 16 blue). Therefore, the probability of not picking a red marker on the first try is 34/40 or 0.85 (since there are 34 non-red markers).

Because the marker is replaced, the conditions remain the same for the second draw. Hence, the probability of also not picking a red marker in the second draw remains at 0.85.

As these are two independent events, the total probability of neither marker being red is found by multiplying the probabilities of the individual events. Hence, 0.85 * 0.85 = 0.7225. Hence the probability that neither marker is red is 0.7225 or 72.25%.

#SPJ12

Final answer:

To find the probability that neither marker is red, calculate the probability of selecting a non-red marker on each draw and multiply the probabilities together.

Explanation:

To find the probability that neither marker is red, we need to calculate the probability of selecting a non-red marker on each draw.  

The total number of markers in the box is 8 (green) + 10 (purple) + 6 (red) + 16 (blue) = 40.

The probability of selecting a non-red marker on the first draw is (8 + 10 + 16)/40 = 34/40 = 17/20.

Since the marker is replaced back in the box, the probability of selecting a non-red marker on the second draw is also 17/20.

The probability that neither marker is red is the product of the individual probabilities: (17/20) * (17/20) = 289/400.

Look at the figure. Find the length of JP.

A.) 8
B.) 2
C.) 4
D.) 6

Answers

Well to start off, we must first establish that line JP and line HP are equal because of the red ticks in the corner. So once we figured that out, then 3x-6 = x+2

»Next we add 6 to both side to make 3x = x+8
»Then we subtract x from both sides to equal 2x = 8
»Then we divide both sides by 2 which equals x=4

»So the final answer would be C. 4
Final answer:

By using the provided scale factor of 2, we multiply the side length of the first square by 2 to find that the length of JP is 8 inches.

Explanation:

To find the length of JP, we must consider the information given about the dimensions of the larger square. Since the problem states that the dimensions of the larger square are twice that of the first square, we know there is a scale factor of 2 involved in the sizing of the squares. Thus, if the side length of the first square is 4 inches, the side length of the larger square would be 4 inches × 2 = 8 inches.

A population of 110,000 grows 3% per years 15 years. How much will the population. How much will the population be after 15 years? Terms of x

Answers

Answer:

The population be after 15 years is 171376.

Step-by-step explanation:

Given : A population of 110,000 grows 3% per years 15 years.

To find : How much will the population be after 15 years?

Solution :

Exponential growth population model is given by,

[tex]P(t)=P_o(1+r)^t[/tex]

Where,

P(t) is the population at time (t)

[tex]P_o=110,000[/tex] is the initial value of the population

r=3%=0.03 is the annual rate of growth

t=15 is the time in years.

Substitute the value,

[tex]P(t)=110000(1+0.03)^{15}[/tex]

[tex]P(t)=110000(1.03)^{15}[/tex]

[tex]P(t)=110000\times 1.5579[/tex]

[tex]P(t)=171376.41[/tex]

Therefore, the population be after 15 years is 171376.

Final answer:

The future population after 15 years of 3% annual growth starting with a population of 110,000 is calculated using the exponential growth formula, resulting in approximately 171,380 people.

Explanation:

To calculate the future population given a current population, growth rate, and number of years, you can use the formula for exponential growth:

P(t) = P0 ×[tex](1 + r)^{t}[/tex]

Where:

P(t) is the population after t years.

P0 is the initial population.

r is the annual growth rate (expressed as a decimal).

t is the time in years.

In this case, the initial population (P0) is 110,000, the growth rate (r) is 3% or 0.03, and the time (t) is 15 years.

Applying these values to the formula:

P(15) = 110,000 × (1 + 0.03)¹⁵

Now we compute the amount (rounded to the nearest whole number):

P(15) = 110,000 × 1.03¹⁵

P(15) ≈ 110,000 × 1.558

P(15) ≈ 171,380

Therefore, the population after 15 years will be approximately 171,380 people.

How do you do congruent angles

Answers

Answer:

 Angles are congruent if they have the same angle measure in degrees.

Angles are congruent if they have the same angle measure in degrees. They can be at any orientation on the plane. In the figure above, there are two congruent angles. Note they are pointing in different directions. If you drag any of the endpoints, the other angle will change to remain congruent with the one you are changing.

For angles, 'congruent' is similar to saying 'equals'. You could say "the measure of angle A is equal to the measure of angle B". But in geometry, the correct way to say it is "angles A and B are congruent".

To be congruent the only requirement is that the angle measure be the same, the length of the two arms making up the angle is irrelevant. As you drag the orange dots above, note how the line lengths will vary but the angles remain congruent, because only the angle measure in degrees matters <3

5/20=x/120

Multiply both sides by 120 to get x by itself

120(5/20)=(x/120)120

Answer:

To make any decimal a fraction, you just add a denominator that has one more digit. Ex: .5 has 1 digit. So add 1 zero, and you get 10 as the denominator.

1, 14/10, 141/100, 1414/1000, 14142/10000, 141421/100000

Final answer:

The given decimals can be converted to fractions based on the decimal place values. Therefore, 1 converts to 1, 1.4 to 14/10, 1.41 to 141/100, 1.414 to 1414/1000, 1.4142 to 14142/10000, and 1.41421 to 141421/100000.

Explanation:

The numbers given can be written as fractions by considering the place value of the digits after the decimal point. Here is the conversion:

1 can be written as 1/1 or just 1 as there is no decimal part.1.4 can be written as 14/10 because 4 is in the tenths place.1.41 is 141/100 as 1 is in the hundredth place.1.414 can be written as 1414/1000 since 4 is in the thousandths place.1.4142 is 14142/10000 as 2 is in the ten-thousandths place.1.41421 can be written as 141421/100000 because 1 is in the hundred-thousandths place.
