Worth 19 points

Answer:

Step-by-step explanation:

To find the class limits for the lowest class, you need to know the class interval, which is the difference between the upper class limit and the lower class limit of each class1. You can find the class interval by subtracting the first two class midpoints: 72.5 - 69.5 = 3.

Then, you can find the lower class limit of the lowest class by subtracting half of the class interval from the first class midpoint: 69.5 - 1.5 = 68.

Similarly, you can find the upper class limit of the lowest class by adding half of the class interval to the first class midpoint: 69.5 + 1.5 = 71.

Therefore, the class limits for the lowest class are 68 and 71.

The building is 19.078 feet tall.

Given:

A 20-foot ladder is leaning against a building in order to reach the roof. the foot of the ladder is 6 feet from the building.

Let x be the building height.

here it forms a right angled triangle,

ladder length (hypotenuse) = 20 feet.

base length = 6 feet

According to pythagorean theorem,

\(hypotenuse^{2} = side^{2} +side^{2}\)

\(20^{2} =6^{2} +x^{2}\)

400 = 36 + \(x^{2}\)

\(x^{2}\) = 400 - 36

\(x^{2}\) = 364

x = \(\sqrt{364}\)

x = 19.078 feet.

Therefore the height of the building is 19.078 feet.

The question is incomplete, below is a possible match to the complete question:

The Chambers family has a net monthly income of $6,500. A circle graph titled Chambers Family Budget. Housing is 25 percent, Food is 20 percent, Savings is 7 percent, Transportation is 12 percent, medical is 10 percent, clothing is 18 percent, emergency fund is 8 percent. If the family decides to reduce its clothing budget by $200 a month, how much will the new clothing budget be? Round to the nearest dollar.

$161

$853

$970

$1,170

The correct answer is $970

Step-by-step explanation:

To calculate the old budget for clothing, let us first convert from percentage to monetary value, and this is done as follows:

Clothing = 18% of monthly income

where: monthly income = $6,500

∴ clothing = 18/100 × 6,500

= 0.18 × 6,500 = $1,170

old budget = $1,170

If the family decides to reduce its clothing budget by $200 a month, the new budget will be:

New budget = old budget - $200

= 1,170 - 200 = $970.

Therefore, the new budget will be $970

30 groups with 20 jellybeans each.

24 groups with 25 jellybeans each.

12 groups with 50 jellybeans each.

10 groups with 60 jellybeans each.

8 groups with 75 jellybeans each.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Chloe wants to divide 600 jellybeans into equal groups. She wants each group to have more than 10 jellybeans, but less than 100.

This means,

we need to find three numbers between 10 and 100 that are a factor of  600.

We  can have,

24 groups with 25 jellybeans each.

12 groups with 50 jellybeans each.

10 groups with 60 jellybeans each.

8 groups with 75 jellybeans each.

These are the possible grouping we can have,

We can choose any three groupings.

Thus,

The possible groupings are:

50 groups with 12 jellybeans each.

40 groups with 15 jellybeans each.

30 groups with 20 jellybeans each.

24 groups with 25 jellybeans each.

12 groups with 50 jellybeans each.

Domain: {-10, -8, -6, -4}

Range: {-5, -4, -3, -2}

Step-by-step explanation:

The domain is a set of all the x's. Here you were given points and the first number in the parenthesis is the x in (x, y). Sometimes they will give you a table or a graph. But domain is all the x's gathered together. I put them in order from small to big to be neat. There aren't any repeats here, but if there ever are repeats you don't have to list them multiple times, just once.

The range is all the y's in the points (x, y) its the second number. Gather all the y's in a set, that is the range.

To find the value of f(6), we can use the information given about the function f(x) and its derivative f'(x).The value of f(6) is 44/3.

Given that f'(x) is continuous, we can apply the Fundamental Theorem of Calculus. According to the theorem:

∫[a to b] f '(x) dx = f(b) - f(a)

In this case, we are given that:

∫[1 to 6] 6 f '(x) dx = 16

We can simplify the integral:

6 ∫[1 to 6] f '(x) dx = 16

Since f'(x) is the derivative of f(x), the integral of 6 f '(x) dx is equal to 6 f(x). Therefore, we have:

6 f(6) - 6 f(1) = 16

Substituting the given value f(1) = 12:

6 f(6) - 6(12) = 16

6 f(6) - 72 = 16

Next, we isolate the term with f(6):

6 f(6) = 16 + 72

6 f(6) = 88

Finally, we solve for f(6) by dividing both sides by 6:

f(6) = 88 / 6

f(6) = 44/3

The units of the correlation are the same as the units of the variable y.

The correlation coefficient measures the strength and direction of the linear relationship between two variables, usually denoted as x and y. The correlation coefficient is a dimensionless quantity that ranges from -1 to +1. However, the units of the correlation are the same as the units of the variable y.

This means that if y is measured in a specific unit (e.g., meters, kilograms, dollars), the correlation will also have the same unit.

The reason for this is that the correlation is calculated based on the values of the variables themselves, without any conversion or transformation of the units. Therefore, the units of the correlation will directly reflect the units of the variable y.

The total surface area of the trapezoidal prism is S = 3,296 inches²

Given data ,

Let the total surface area of the trapezoidal prism is S

Now , the measures of the sides of the prism are

Side a = 10 inches

Side b = 32 inches

Side c = 10 inches

Side d = 20 inches

Length l = 40 inches

Height h = 8 inches

Lateral area of prism L = l ( a + b + c + d )

L = 40 ( 10 + 32 + 10 + 20 )

L = 2,880 inches²

Surface area S = h ( b + d ) + L

On simplifying the equation , we get

S = 2,880 inches² + 8 ( 52 )

S = 3,296 inches²

To write 9 in Roman Numerals, you would use the symbols "IX".

The symbol "I" represents the number 1 and the symbol "X" represents the number 10. When a smaller symbol is placed before a larger symbol, it means that the smaller symbol is subtracted from the larger symbol.

In this case, "I" is placed before "X", so it is subtracted from 10, giving us the value of 9.

Here is a step-by-step explanation:

1. Identify the symbols for 1 and 10: "I" and "X"
2. Place the smaller symbol before the larger symbol: "IX"
3. Subtract the smaller symbol from the larger symbol: 10 - 1 = 9
4. The result is the value of the Roman Numeral: "IX" = 9

Therefore, the Roman Numeral for 9 is "IX".

There are 60 seconds in a minute and 60 minutes in an hour. To find the total number of instructions the computer can perform in an hour, we need to multiply the number of instructions per second by the number of seconds in an hour.

Number of seconds in an hour = 60 seconds/minute × 60 minutes/hour = 3600 seconds/hour

Total number of instructions per hour = instructions per second × seconds per hour

= 4.66 × 10^8 instructions/second × 3600 seconds/hour

= 1.6776 × 10^12 instructions/hour

Therefore, the computer can perform 1.6776 x 10^12 instructions per hour.

The code segment is given in Python. So, it must be completed in Python.

The missing nested loops are as follows:

for rows in range(num_rows):

  for cols in range(num_cols):

The first nested loop will iterate through the length of the rectangle

for rows in range(num_rows):

The second nested loop will iterate through the width

  for cols in range(num_cols):

So, the complete program is:

num_rows = int(input())

num_cols = int(input())

for rows in range(num_rows):

  for cols in range(num_cols):

      print('*',end=' ')

  print()
