The difference between the median test score in the morning and the afternoon is 12.5

From the question, we are to determine the difference between the median test score in the morning and the afternoon.

From the given diagram, we have box plots.

From the given box plots, we will determine the median test score in the morning and the median test score in the afternoon.

The median test score in the morning = 87.5

The median test score in the afternoon = 75

Thus,

The difference between the median test score in the morning and the afternoon =

Median test score in the morning - Median test score in the afternoon

The difference between the median test score in the morning and the afternoon = 87.5 - 75

The difference between the median test score in the morning and the afternoon = 12.5

Hence,

The difference is 12.5

1. To find the probability that the length of a single trout taken at random from the pond is between 7 and 11 inches long, we need to use the normalcdf command with the given parameters. The formula for normalcdf is normalcdf(lower bound, upper bound, mean, standard deviation).

Thus, normalcdf(7, 11, 10.5, 1.2) = 0.6827.

Therefore, the probability that the length of a single trout taken at random from the pond is between 7 and 11 inches long is 0.6827.

2. To find the probability that the mean length of five trout taken at random is between 7 and 11 inches, we need to use the central limit theorem, which states that the sample mean will also follow a normal distribution with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size (i.e., sigma/sqrt(n)).

Thus, we first need to find the standard deviation of the sample mean, which is sigma/sqrt(n) = 1.2/sqrt(5) = 0.5367.

Then, we can use the normalcdf command with the given parameters. The formula for normalcdf is normalcdf(lower bound, upper bound, mean, standard deviation).

Thus, normalcdf(7, 11, 10.5, 0.5367) = 0.9468.

Therefore, the probability that the mean length of five trout taken at random is between 7 and 11 inches is 0.9468.

The number of children ticket sold is 90 while the number of adult ticket sold is 200.

Math land theatre charges $5.00 for children's tickets and $9.00 for adult tickets. One night the theatre sold 290 tickets and took in $2250.

Therefore, let's find the number of each type of ticket sold as follows:

Hence,

Let

Therefore, using equation,

c + a = 290

5c + 9a = 2250

Multiply equation(i) by 5

5c + 5a = 1450

5c + 9a = 2250

subtract the equation

4a = 800

divide both sides by 4

a = 800 / 4

a = 200

Therefore, let's find c

c = 290 - 200

c = 90

Step-by-step explanation:

Let P(t) be the fox population t years after 2000. We know that the population has a continuous growth rate of 4% per year, which means that the population increases by a factor of 1.04 each year. Therefore, we can model the population as:

P(t) = 21400 * 1.04^t

Here, we start with the population in the year 2000 (21400) and multiply it by 1.04 raised to the power of the number of years after 2000 (t).

For example, if we want to find the population in the year 2015 (15 years after 2000), we can plug t = 15 into the equation:

P(15) = 21400 * 1.04^15

= 21400 * 1.618

= 34694.8

Therefore, we can expect the fox population to be approximately 34,695 in the year 2015.

The cost of the utility pole with a radius of 17.8 cm and a height of 700 cm is; $3774.4

From the information given, we have the following parameters;

Density = 5.4 g/cm³

Mass = Ikg = 0.71 kg

Cost per mass = $0. 51

Let's determine the volume of this cylinder:

Volume = mass / density

Substitute the values

Volume = 0.71 /5.4

Volume = 0.131 cm³

Thus, 0.131  cm³ costs $0.71

For the utility pole;

Volume = 2 πr²h

Where:

r is 17.8cm

height is 700cm

Volume = 3. 142 × 17.8 × 17.8 × 700

Volume = 696414.32 cm³

If  0.131  cm³ costs $0.71

Then  696414.32  cm³ will cost:

= 696414.32   × 0.71/ 0.131  

= 3774.4

Composition is a mathematical operation that combines two functions to form a new function. From our question, we are given two functions f(x) and g(x).

One of their composition can be represented by f(g(x)).f(g(x)) means function out of g(x) will serve as input x for function f(x). In a more simpler words, f(g(x)) is the function obtained by taking the output of g(x) and using it as the input for f(x).

Using the question given as an example,

For f.g:

Firstly, we have to compute the composition of f and g.

This can be expressed as:

f(g(x))f(g(x)) = f(√(4x-1))= 1/[5(√(4x-1))² + 3]= 1/[5(4x-1) + 3]

= 1/(20x + 10)

For f+g:

To find f+g, we will just add the two functions together as below:

f+g = 1/(5x²+3) + √(4x-1)= (√(4x-1) + (5x²+3)

By calculating the volume of both figures, we will see that 11,160 cubes can be fit in the prism.

Now, So we start with a rectangular prism that measures (7 + 1/2)cm by 12cm by (15 + 1/2) cm.

Hence, The volume is just the product of these 3 values,

so we get:

V = (7 + 1/2)cm × 12cm × (15 + 1/2)cm

V = 1,395 cm³

Now, a cube with an edge length of 1/2 cm has a volume of:

V' = (1/2cm)³

V' = 0.125 cm³

To see how many of the small cubes enter in the prism, we just need to take the quotient between these two volumes, this is:

V/V' = ( 1,395 cm³)/(0.125 cm³) = 11,160

This means that, 11,160 of the cubes can be fit in the prism.

Answer:

1/20

Step-by-step explanation:

To multiply two fractions, you simply multiply their numerators (top numbers) together and multiply their denominators (bottom numbers) together.

So, for 2/5 x 1/8, we have:

(2/5) x (1/8) = (2 x 1) / (5 x 8) = 2/40 = 1/20

Therefore, 2/5 x 1/8 is equal to 1/20.

Multiplying the numerators and denominators directly is the most straightforward method to solve the multiplication of fractions. However, there is another method called cross-multiplication, which you can use to solve this problem as well.

To use cross-multiplication, you multiply the numerator of the first fraction by the denominator of the second fraction, and then multiply the denominator of the first fraction by the numerator of the second fraction.
Then, you simplify the resulting fraction.

So, for 2/5 x 1/8, we have:

(2/5) x (1/8) = (2 x 1) / (5 x 8)

Cross-multiplying, we get:

(2/5) x (1/8) = (2 x 1) / (5 x 8) = (2 x 1) / (5 x 8) = 2/40

Simplifying the fraction 2/40, we can divide both the numerator and denominator by 2, to get:

2/40 = 1/20

Therefore, using cross-multiplication, we get the same answer as before:

2/5 x 1/8 is equal to 1/20.
