Paris used a simulation to take two random samples of fish in a pond. Her sample size was 30, and the table shows the frequency

of each fish in the sample. Paris used the two samples to predict that the average number of trout will be 6, the average number of catfish will be 5, and the average number of bass will be 18.
A 3-column table with 3 rows. Column 1 is labeled Fish type with entries brook trout, catfish, smallmouth bass. Column 2 is labeled Frequency Sample 1 with entries 12, 5, 13. Column 3 is labeled Frequency sample 2 with entries 1, 6, 23.

Is Paris correct in her predictions? Check all the apply.
Yes, her samples represent the population.
No, Paris should have used only the results of the first sample.
No, Paris should have used only the results of the second sample.
No, the two samples do not have similar values, so more samples are needed.
No, the samples are not representative of the population.

Answer:

looking at the questions, the only possible ones that are available are

- No, the two samples do not have similar values, so more samples are needed.

Answer:

No, let's take a look back at the question

Step-by-step explanation:

Samples are literally representation of the population.

The true statements are:

D. No, the two samples do not have similar values, so more samples are needed.

E. No, the samples are not representative of the population.

From the table, the difference between the frequencies of book trout and bass fish are too large.

This means that the prediction do not estimate actual sample

So, the true options are (d) and (e)

You are choosing between two different cell phone plans. The first plan charges a rate of 25 cents per minute. The second plan c
bogdanovich [222]

Answer:You would have to use over 200 minutes in a month in order for the second plan to be preferable.

Step-by-step explanation:

Let x represent the number of minutes that you use in a month.

The first plan charges a rate of 25 cents per minute. It means that the cost of using x minutes in a month with this plan is 0.25x.

The second plan charges a monthly fee of $29.95 in addition to 10 cents per minute. It means that the cost of using x minutes in a month with this plan is

29.95 + 0.1x

For the second plan to be preferable, its cost would be lesser than the first plan. Therefore,

29.95 + 0.1x < 0.25x

29.95 < 0.25x - 0.1x

29.95 < 0.15x

0.15x > 29.95

x > 29.95/0.15

x > 200

Find the area of a circle that has a diameter of 11 inches. Approximate Π as 3.14. Round your answer to the nearest hundredth.
Alexus [3.1K]

Answer: 94.99 in^2

Step-by-step explanation: The equation for the area of a circle is A=πr^2. To solve this, we need to find the radius. The diameter is the whole circle, whole the radius is half. So divide the diameter by 2.

11/2 = 5.5

The radius is 5.5 inches. Plug the radius into the equation.

A=π5.5^2

Square the 5.5 first. You will get 30.25.

A=π30.25

Plug in 3.14 for pi.

A=3.14 x 30.25

Multiply.

A=94.985

Round to the nearest hundredth.

A=94.99

The area of the circle is 94.99 in^2.

What is the equation of a line (in standard form) that passes through point A(1,-4) and has a slope of 3/4?
Anna35 [415]

Answer:

3x-4y=19

Step-by-step explanation:

Hi there!

We want to write the equation of the line in standard form that passes through the point (1, -4) and has the slope of 3/4

Standard form is written as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0, and a cannot be negative

First, in order to find ax+by=c, we'll need to get slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

Since we already know the slope (3/4), we can substitute it into the formula for y=mx+b.

y=3/4x+b

Now we need to solve for b

Since the equation passes through the point (1, -4), we can use it to solve for b

Substitute 1 as x and -4 as y.

-4=3/4(1)+b

Multiply

-4=3/4+b

Subtract 3/4 from both sides

-19/4=b

Now substitute -19/4 as b into the equation

y=3/4x-19/4

Now we have the equation in slope-intercept form, but remember, we want it in standard form

Since x and y are on the same side in standard form, subtract 3/4x from both sides

-3/4x+y=-19/4

Remember that a cannot be negative, and the coefficients are integers (they cannot be fractions)

So in order to clear the fractions and change the sign of the equation, multiply both sides by -4

-4(-3/4x+y)=-4(-19/4)

Multiply

3x-4y=19

Hope this helps!
