chris calculated the volume of three identical boxes.one of the boxes is modeled in the diagram.what is the combined volume of the three boxes in cubic feet

The average of 7 numbers will be 14.

To calculate the average of the 7 numbers, we need to determine the sum of all the numbers and then divide it by 7. Since we know the average of the first two numbers is 9, we can multiply it by 2 to find the sum of those two numbers.

Similarly, since we know the average of the last five numbers is 16, we can multiply it by 5 to find the sum of those numbers.

Adding the sum of the first two numbers to the sum of the last five numbers will give us the sum of all 7 numbers. Finally, dividing this sum by 7 will give us the average of the 7 numbers.

the range in this set of data is 25 inches. To find the range of snowfall amounts, we need to look at the line plot and identify the highest and lowest amounts of snowfall that were recorded.

The range in a set of data is the difference between the maximum and minimum values in the set.

To find the range of snowfall amounts, we need to look at the line plot and identify the highest and lowest amounts of snowfall that were recorded.

Let's say that the highest amount recorded was 30 inches and the lowest amount recorded was 5 inches. Then the range would be:

range = highest amount - lowest amount

range = 30 - 5

range = 25

Therefore, the range in this set of data is 25 inches.

Answer:

The answer for the Area is 8

Step-by-step explanation:

A=8

Answer:

32 or 100.53

Step-by-step explanation:

*assuming 8 is radius and not diameter*

A = \(r^{2}\)

r = 8

\(8^{2} = 64\)

A = 64 or ≈201.062

divide by 2 for half of the circle

The statement "The mean decreases as the degrees of freedom increase" is not true about chi-square distributions.

In fact, the mean of a chi-square distribution is equal to its degrees of freedom. It does not decrease as the degrees of freedom increase.

The mean remains constant regardless of the degrees of freedom. This is an important characteristic of chi-square distributions.

Regarding the other statements:

In summary, the statement that is not true about chi-square distributions is that the mean decreases as the degrees of freedom increase.

The solution of given equation for n would be n = (2c - 2)/(-p)

In this question, we have been given an equation.

We solve given equation for n.

−np − 4 = 2(c − 3)

−np − 4 + 4 = 2(c − 3) + 4

−np= 2c - 6 + 4

-np = 2c - 2

np = -2c + 2

np * 1/p = (-2c + 2) * (1/p)

n = (-2c + 2)/p

n = (2c - 2)/(-p)

Therefore, the solution of given equation for n would be n = (2c - 2)/(-p)

Step-by-step explanation:

See comment for proper format of question

Let their present ages be x and y

So:

\(x : y = 3 : 4\)

5 years time, the ratio will be:

\(x + 5: y + 5= 4 : 5\)

Required

Their present ages

Express both ratios as fractions

\(x : y = 3 : 4\) becomes

\(\frac{x}{y} = \frac{3}{4}\)

and

\(x + 5: y + 5= 4 : 5\) becomes

\(\frac{x+5}{y+5} = \frac{4}{5}\)

Make x the subject in: \(\frac{x}{y} = \frac{3}{4}\)

\(x = \frac{3}{4}y\)

\(x = 0.75y\)

Cross multiply in \(\frac{x+5}{y+5} = \frac{4}{5}\)

\(5(x + 5) = 4(y + 5)\)

Substitute \(x = 0.75y\)

\(5(0.75y + 5) = 4(y + 5)\)

Open brackets

\(3.75y + 25 = 4y + 20\)

Collect like terms

\(3.75y -4y = -25 + 20\)

\(-0.25y = -5\)

Divide by -0.25

\(y = 20\)

Substitute \(y = 20\) in \(x = 0.75y\)

\(x = 0.75 * 20\)

\(x = 15\)

Joan saved a total of $78 from her $390 weekly income each week.

What is percentage?

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. Percentage means 1 part from hundreds and represented by the symbol '%'. Percentages have no dimensions. Therefore, it is called a dimensionless number.

Percentage = (value/total value)× 100

We have, Joan's income = $390/week

Saving = 20% from her weekly salary.

We have to calculate how much does she save each week. Joan save 20% of her weekly income (i.e $390). let Joan saved $x each week from her sallary. The saved income in dollars each week by Joan i.e ($x) is equals to 20% of 390

x =( 20/100)× 390

=> x = 390/5

=> x = 78

Hence, Joan saves $78 each week.

According to the box plot we have:

The IQR is the difference of Q3 and Q1:

The inequality to represent the possible number of hours Kat can afford to book the DJ is 80x + 225 ≤ 970 and one possible length Kat can afford to book the DJ is 9 hours.

(a) Let x be the number of hours that Kat can book the DJ. Then, the total cost of the DJ is 80x, and the total cost of the party is 80x + 225.

Since Kat has $410 saved and will earn another $560, the total amount she can spend on the party is $410 + $560 = $970.

Therefore, we can write the following inequality to represent the possible number of hours Kat can afford to book the DJ:

80x + 225 ≤ 970

b) To solve for x, we can start by subtracting 225 from both sides of the inequality:

80x ≤ 745

Then, we can divide both sides by 80:

x ≤ 9.3125

Since Kat can only book the DJ in whole hours, the largest integer less than or equal to 9.3125 is 9. Therefore, one possible length Kat can afford to book the DJ is 9 hours.

I am not fine dear becoz my answers are always being deleted these I third time for me my points are so less now☹☹

Answer:

This is how it should like like

The distance between points M(6, 16) and Z(-1, 14) is approximately 7.1 units.

We can use the distance formula to find the distance between two points in a coordinate plane. The distance formula is:

d = √((x2 - x1)² + (y2 - y1)²)

where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the coordinates of M(6, 16) and Z(-1, 14), we get:

d = √((-1 - 6)² + (14 - 16)²) = √(49 + 4) = √53 ≈ 7.1

Therefore, the distance between points M(6, 16) and Z(-1, 14) is approximately 7.1 units.

Let's assume the sum of the scores of the 28 students who took the test yesterday is 28 * 72 = 2016.

We know that the sum of the scores of all 30 students is (28 * 72) + x + y, where x and y are the scores of the two students who took the test this morning.

We also know that the mean of all 30 scores is 73. So we can write an equation:

[(28 * 72) + x + y]/30 = 73

Multiplying both sides by 30, we get:

2016 + x + y = 2190

So, x + y = 174.

We are given that the difference of the two scores is 22, so we can write another equation:

y - x = 22

Solving these two equations simultaneously, we get y = 98 and x = 76.

Therefore, the lower score from this morning is 76.

On the Fahrenheit temperature scale, water freezes at 32 degrees and boils at 212 degrees.


The Fahrenheit temperature scale is commonly used in the United States and a few other countries. On this scale, water freezes at 32 degrees Fahrenheit (°F) and boils at 212 °F. These values are based on the freezing and boiling points of water at standard atmospheric pressure. When the temperature drops below 32 °F, water molecules slow down and form a solid, resulting in the state of freezing.

On the other hand, when the temperature rises to 212 °F, water molecules gain enough energy to transition into a gas, leading to the process of boiling. These temperature points are essential for various daily activities and scientific applications that rely on the Fahrenheit scale.
