Based on the histogram above, the class width is equal to 4.

Based on the histogram above, the sample size is equal to 37.

In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.

Mathematically, the class width of a data set can be calculated by using this formula:

Class width = (max - min)/n

Where:

In this context, the class width of this histogram can be calculated as follows;

Class width = max - min

Class width = 5 - 1

Class width = 4.

Furthermore, the sample size can be computed by adding all the frequencies of the corresponding rectangular bars of the histogram as follows;

Sample size = 6 + 10 + 4 + 2 + 7 + 8

Sample size = 37.

Answer: 30

Step-by-step explanation:

Think of each number in the ratio of 2:5 as a group. Each group has to be the same. 2 groups of boys : 5 groups of girls. There are 12 boys on the bus. So the 12 boys are split into 2 groups. 12/2=6. 6 boys are in each group. Since we now know that each group had 6 kids we just need to find the number of girls. There are 5 groups of 6 girls. 5x6=30. There are 30 girls on the bus.

Answer:

y=2x+6

Step-by-step explanation:

First find the gradient of the perpendicular line. We can do this by turing the given gradient into a negative reciprocal.

-1/2 -> 2 (new gradient)

substitute new gradient into y=mx+c as well as the values for x and y from the given coordinate (-2,2)

y=mx+c

2=2(-2)+c

then solve for c

2=-4+c

c=6

therefore the formula for the line is y=2x+6

The products of the matrices are

        [-4     19]

ST =  [8   -21]      

and

        [-12      -8]

TS = [-25      -10]

The matrices are given as

      [4      1]

S =  [-3   -2]

      [0      4]

T =  [-4   3]

The product of the matrices is then calculated as

        [4 * 0 + 1 * -4      4 * 4 + 1 * 3]      

ST =  [-3 * 0 - 2 * -4   -3 * 4 - 3 * 3]      

Evaluate the sum or difference of products

So, we have

        [-4     19]

ST =  [8   -21]      

Also, we have

        [0 * 4 + 4 * -3      0 * 1 + 4 * -2]      

TS = [-4 * 4 + 3 * -3      -4 * 1 + 3 * -2]      

Evaluate the sum or difference of products

So, we have

        [-12      -8]

TS = [-25      -10]

Hence, the products of the matrices are

        [-4     19]

ST =  [8   -21]      

and

Answer:

  A  irrational

  B  real

Step-by-step explanation:

Given the value π/7, you want to classify it as whole, integer, real, and/or irrational.

Any number that does not have an imaginary part is a real number. Real numbers include integers, whole numbers, and natural numbers, none of which have any fractional part.

Any ratio of integers (with a non-zero denominator) is a rational number. All other real numbers are irrational numbers. Pi (π) is an irrational number.

When rational numbers are written as decimal numbers, their fractional part will either terminate or repeat. When the fractional part of a decimal number does not terminate or repeat, but continues indefinitely, the number is irrational.

As we said, pi is an irrational number. Multiplying it by a rational number (1/7) does not change its classification.

  π/7 is irrational and real

The area of the rectangle whose diagonal is twice its width is (x²√3)/4  square units.

The area of rectangle is defined by the product of its length and width. Mathematically-

Area [A] = Length [L] x Width [W]

Given is a rectangle whose diagonal is twice as long as it's width. From this, we can write -

Width = w

Length of diagonal = x = 2w

Assume that the length of the rectangle is L. Using the Pythagoras theorem in the triangle ΔABC, we get -

AC² = AB² + BC²

x² = L² + w²

(2w)² = L² + w²

4w² = L² + w²

L² = 3w²

L = w√3

Now, the width of rectangle is 'w' and its length is 'w√3'. Its area will be-

Area = length x width

A = w√3 × w

A = w²√3

Now, length of diagonal → x = 2w. So, we can write -

w = x/2

Therefore, the area will be -

A = (x/2)²√3 = (x²√3)/4

Therefore, the area of the rectangle whose diagonal is twice its width is (x²√3)/4  square units.
