Answer:

4/5 of an hour

Step-by-step explanation:

3/10 of an hour (60 minutes) equals 18 minutes

3/4 of 5 km equals 3.75 km

therefore, you can create a ratio of minutes over km equals min over km

let 't' = time

18/3.75 = t/10

cross-multiply to get this equation:

3.75t = 180

divide each side by 3.75 to get:

t = 48 minutes

48 minutes out of 60 minutes equals 4/5 of one hour

The main idea behind statistical inference is that through the use of sample data, we are able to draw conclusions about the population from which the data was drawn (option c).

Statistical inference allows us to make inferences and draw conclusions about a larger population based on the analysis of a smaller representative sample.

By collecting data from a sample, we can use statistical methods to analyze and summarize the information. These methods include estimating population parameters, testing hypotheses, and making predictions.

The key assumption underlying statistical inference is that the sample is representative of the larger population, allowing us to generalize the findings to the population as a whole.

Statistical inference provides a way to make reliable and informed decisions, identify patterns and relationships, and make predictions about future observations based on the available data. It allows researchers, scientists, and decision-makers to make evidence-based conclusions and draw meaningful insights from limited observations.

The midpoint between A and E is (0,1)

The coordinates of the cities are given as:

A(-2,3), B(2,7), C(7,8), D(6,3) and E(2,-1).

From the above, we have:

A = (-2,3)

E = (2,-1)

The midpoint between A and E is calculated using

Midpoint = 1/2 * (x1 + x2, y1 + y2)

Substitute the known values in the above equation

Midpoint = 1/2 * (-2 + 2, 3 - 1)

This gives

Midpoint = 1/2 * (0, 2)

Evaluate the product

Midpoint = (0, 1)

Hence, the midpoint between A and E is (0,1)

Brock is at a distance of 621/40 miles away from home.

Here, we are given that Brock rides his bike 22 1/8 miles to the nature preserve.

This means that he is now 22 1/8 miles away from his home. Now, he starts on his way home and after 16 1/5 miles, he stops at a deli for lunch.

Thus, he is now 22 1/8 - 16 1/5 miles away from his home.

To subtract the fractions we need to convert the mixed fractions into improper fractions, which can be done as follows-

22 1/8 = (22*8 + 1)/8

= 177/8

and 16 1/5 = (16*5 + 1)/5

= 33/5

Thus, the expression becomes-

177/8 - 33/5

now, we need to make the denominators of each fraction so that we can subtract them.

= (177*5)/40 - (33*8)/40

= 885/40 - 264/40

= 621/40

Thus, Brock is at a distance of 621/40 miles away from home.

Step-by-step explanation:

formula is m = (y2-y1)/(x2-x1)

It will take 5 minutes to print a batch of newspapers if 20 printers are used.

What is proportionality?

Proportionality is a mathematical relationship between two variables, where one variable is a constant multiple of the other. In other words, two quantities are proportional if they maintain a constant ratio to each other, meaning that as one quantity increases or decreases, the other quantity changes in the same proportion.

We are given that the time it takes to print a batch of newspapers, m, is inversely proportional to the number of printers used, n, and the equation of proportionality is:

m = k/n

where k is a constant of proportionality. We are also given that when k = 100, the equation is satisfied. So we can substitute k = 100 into the equation to get:

m = 100/n

To find the time it will take to print a batch of newspapers if 20 printers are used, we can substitute n = 20 into the equation:

m = 100/20 = 5

So it will take 5 minutes to print a batch of newspapers if 20 printers are used. Rounded to 1 decimal place, the answer is 5.0 minutes.

Given:

The values are \(a=0.\overline{6},b=0.75\).

To find:

The values of \(ab\) and \(\dfrac{a}{b}\).

Solution:

We have,

\(a=0.\overline{6}\)

\(a=0.666...\)                     ...(i)

Multiply both sides by 10.

\(10a=6.666...\)                 ...(ii)

Subtracting (i) from (ii), we get

\(10a-a=6.666...-0.666...\)

\(9a=6\)

\(a=\dfrac{6}{9}\)

\(a=\dfrac{2}{3}\)

And,

\(b=0.75\)

\(b=\dfrac{75}{100}\)

\(b=\dfrac{3}{4}\)

Now, the product of a and b is:

\(ab=\dfrac{2}{3}\times \dfrac{3}{4}\)

\(ab=\dfrac{1}{2}\)

The quotient of a and b is:

\(\dfrac{a}{b}=\dfrac{\dfrac{2}{3}}{\dfrac{3}{4}}\)

\(\dfrac{a}{b}=\dfrac{2}{3}\times \dfrac{4}{3}\)

\(\dfrac{a}{b}=\dfrac{8}{9}\)

Therefore, the required values are \(ab=\dfrac{1}{2}\) and \(\dfrac{a}{b}=\dfrac{8}{9}\).

What we can say about molecules is that they  violates the law of definite proportions.

The law of definite proportions, also known as Proust's law or the law of constant composition, is a principle in chemistry that asserts a chemical compound will always contain its constituent components in a fixed ratio (by mass), regardless of its source or method of creation.

All molecules in the gaseous state and smaller molecular compounds in other states of matter are subject to the law of definite proportions, however polymers are exempt from its application. Even with identical monomers, the length, branching, termination, etc. of the polymer molecules varies significantly.

By applying ratio concept, it can be concluded that the required ratio of apple trees to pear trees is 7 : 3.

Ratio is a number that shows a mathematical relationship or comparison between an amount and another amount.

It is usually written in the simplest form so that it is easier to understand through a process of simplification.

Number of apple trees = 28

Number of pear trees = 12

So the rasio between apple trees and pear trees can be written as 28 : 12.

As we want to get the simplest form, we divide each number by 4, so we get 7 : 3.

Thus, the required ratio of apple trees to pear trees is 7 : 3.

There are 9 possible schedules to play basketball such that dave can play on monday or wednesday or both which is union of two set .

so this question seems like we have to take union of ways of palying on monday or wednesday

let n(m) be number of ways of playing on monday

n(w) be number of ways of playing on wednesday

we have to find n(m∪w)

n(mUw) = n(m) +n (w) - n(m∩ w)

so n(m) = \(4_C__2\) as one day is now fixed which is monday so we have 4 available days and 2 days to play.

n(m) = \(4_C__2\)  = 6

similary n(m) = n(w) = 6

now  n(m∩w) = \(3_C__1\) as now we have  2 fixed day and we have 3 day remaining and only one day to play.

n(m∩w) = \(3_C__1\) =3

now n(mUw) = n(m) +n (w) - n(m∩ w)

=> 6 + 6 -3

=> 12 - 3

so n(mUw) = 9

The expression for the perimeter of the sandwich would be:

2 (2x^2 + 9) + 2 (2x^2 + 8)

= 4x^2 + 26

Now for finding the length of the crust,

The radius of each of the smaller molds is r = 1/3 ft. Using the volume of the given hemisphere, the required radius is calculated.

The volume of the hemisphere is calculated by using the formula,

= \(\frac{2}{3}\) × π × r³ cubic units

where r is the radius of the hemisphere.

It is given that,

A hemisphere-shaped bowl with a radius r = 1 ft is filled with chocolate.

So, the volume of the bowl is

V =  \(\frac{2}{3}\) × π × (1)³

  =  \(\frac{2}{3}\) × π cubic feets

The volume of each smaller hemisphere-shaped mold =  \(\frac{2}{3}\) × π × r³ cubic units

So, for 27 molds, the volume = 27 × \(\frac{2}{3}\) × π × r³ cubic units

All of the chocolate is then evenly distributed between 27 congruent, smaller hemisphere-shaped molds.

Then,

\(\frac{2}{3}\) × π = 27 × \(\frac{2}{3}\) × π × r³

⇒ r³ = 1/27

⇒ r = 1/3 ft

Therefore, the required radius of each of the smaller molds is 1/3 foot.

The Answer is 95 miles using distance rule of maths.

What is distance in math?

As its name implies, any distance formula outputs the distance (the length of the line segment). In coordinate geometry, there is a number of formulas for finding distances, such as the separation between two points, the separation between two parallel lines, the separation between two parallel planes, etc.

So if we mark their position in x-y plane. one is not x line and another one is in y line.

So the coordinates of the points are (57,0) and (0,76)

The distance between them is √(y²+x²)

= √(57²+76²)

=√ (3249 + 5776)

= 95 miles

Hence the distance between them is 95 miles.
