The number of students in Mr Hassan's class is 33 and I assumed that each small square in the graph is 0.5 unit and that there are 10 small squares.

A bar chart displays information (data) by using rectangular bars of different heights.

A bar chart has a vertical axis with numbers on it, and a horizontal axis showing values of something that has been investigated.

from the graph, since each small square represent 0.5 unit, number of student that sored 1 mark = 3

number of student that scored 2 marks = 5

number of student that scored 4 marks = 2

number of student that scored 5 marks = 6

number of student that scored 8 marks = 12

number of student that scored 9 marks = 1

number of student that scored 4 marks = 4

Total number of students = 3 + 5+ 2+ 6 + 12 + 1 + 4 which is 33.

I assumed each small square to be 0.5

In conclusion the total number of student is 33

Answer & Step-by-step explanation:

This question is just a matter of reading the graph correctly. The question is basically asking us how much each color (or the education level) is taking up in the whole bar. So, you just subtract where the color ends from where the color starts.

1997 age 65 or older

Bachelor's degree or higher: 100 - 75 = 25%

College/associate's degree: 75 - 54 = 21%

High school graduates: 54 - 21 = 33%

Less than a high school diploma: 21 - 0 = 21%

Total: 25+21+33+21 = 100%

2007 age 65 or older

Bachelor's degree or higher: 100 - 69 = 31%

College/associate's degree: 69 - 46 = 23%

High school graduates: 46 - 13 = 33%

Less than a high school diploma: 13 - 0 = 13%

Step-by-step explanation: Desmos

Answer:

There are 3 terms

Step-by-step explanation:

Given expression,

→ 5x + y - 3x - 8 + 2

Let's simplify the expression,

→ 5x + y - 3x - 8 + 2

→ (5x - 3x) + y + (-8 + 2)

→ 2x + y - 6

The number of terms are,

→ 2x + y - 6

→ 3 terms (trinomial)

Hence, there are 3 terms.

Answer:

  (b)  A line that goes through (0, 0) and (3.4, 13.6)

Step-by-step explanation:

You want a description of the line that describes the same proportional relationship as the points given in the table:

  (x, y) = (3.4, 13.6), (5.6, 22.4), (1.7, 6.8)

The graph of the relation will be a straight line through points with (x, y) values from the table. A graph of a proportional relation also goes through the point (0, 0).

Of the points listed in the answer choices, only (3.4, 13.6) and (5.6, 22.4) are ones that are given in the table. This eliminates all of the answer choices except the correct one:

  A line that goes through (0, 0) and (3.4, 13.6).

Answer:

Angles 2 and 4 are 107.

Angles 1 and 3 are 73

Step-by-step explanation:

Angle 4 is given.  Angle 2 is the same because vertical angles are congruent.

Angles 1 and 3 are supplemental. They add up to 180 (180 - 107 = 73)

Parallel lines have the same slope.

y = -1/2 x -3 has a slope of -1/2, so the new line has the same slope.

This gives us: y = -1/2 x + b

To find b, substitute in the given point (4,-1):

   -1 = -1/2 (4) + b

   -1 = -2 + b

    1 = b

The new line is  y = -1/2 x + 1.

Answer:

20-29 songs

Step-by-step explanation:

Artists with 20-29 songs had the highest total number of people in the crowd.

The inequality in standard form that describes the situation is 24x + 7y ≥ 31

Total number of required serving of dessert = 31

Number of serving he will get in every batch of brownies = 24 servings

Number of serving he will get in every batch of pie = 7 serving

Consider the number batch of brownies = x

Number of batch of pie = y

The inequality is the mathematical statement that shows the relationship between two expression with an inequality sign. The inequality will be less than, less than or equal, greater than, greater than or equal.

Then the inequality will be

24x + 7y ≥ 31

Hence, the inequality in standard form that describes the situation is 24x + 7y ≥ 31

The speed of the boat in still water is 1miles per hour or 7miles per hour

Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

The formula for speed = Distance /time

For upstream movement ,the boat will move against the velocity of the current and in down stream the boat will move with the velocity of the current.

Therefore speed of the boat in downward movement is (S+3) and the speed of the boat during upward movement is (S-3)

The general formula for speed= d/t

(S+3)= 20/5=4

or

(S-3)= 20/5= 4

Therefore, the speed of the boat in still water is

S= 4-3=1mile/hour

or

S= 4+3= 7miles/hour

Judgement sampling is not a probability sampling technique

Probability sampling is a technique in which the researcher chooses samples from a larger population using a method based on probability theory. For a participant to be considered as a probability sample, he/she must be selected using a random selection.

The most critical requirement of probability sampling is that everyone in your population has a known and equal chance of getting selected.

1. Simple random sampling, as the name suggests, is an entirely random method of selecting the sample. This sampling method is as easy as assigning numbers to the individuals (sample) and then randomly choosing from those numbers through an automated process. Finally, the numbers that are chosen are the members that are included in the sample.

2. Stratified random sampling involves a method where the researcher divides a more extensive population into smaller groups that usually don’t overlap but represent the entire population. While sampling, organize these groups and then draw a sample from each group separately.

3. Random cluster sampling is a way to select participants randomly that are spread out geographically. For example, if you wanted to choose 100 participants from the entire population of the U.S., it is likely impossible to get a complete list of everyone. Instead, the researcher randomly selects areas (i.e., cities or counties) and randomly selects from within those boundaries.

From the above explanation, cluster sampling, simple random sampling and stratified random sampling are types of probability sampling except for judgement sampling.

if x→+∞, then y→-∞ [increasing];

if x→-∞, then y→+∞ [decreasing].

Converting 176 Pints will give 88 Quarts

A conversion factor is a number used to change one set of units to another, by multiplying or dividing

The pint (symbol: pt.) is a unit of volume or capacity. One liquid pint is equal to 473.176473 milliliters (≈ 473 ml).

The quart (abbreviation qt.) is an English unit of volume equal to a quarter gallon. It is divided into two pints or four cups.

To convert 176 Pints to the corresponding value in Quarts,

Multiply the quantity in Pints by 0.5 (conversion factor).

In this case we should multiply 176 Pints by 0.5 to get the equivalent result in Quarts:

176 Pints x 0.5 = 88 Quarts

Hence,176 Pints when converted is 88 Quarts.

The total surface area of the cylinder is 157 square feet.

Given the radius of the cylinder = 4 inches

height of the cylinder = 9 inches

Total surface area is calculated by the formula:

A = 2πr² + 2πh

A = 2 × 3.14 × 4² + 2 × 3.14 × 9

or, A = 157 square feet.

Therefore the total surface area of the cylinder is 157 square feet.

The surface area of a solid item is a measurement of the total volume that the surface of the thing occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more complicated than the definition of arc length for one-dimensional curves.

The definition of surface area for polyhedral (i.e., particles with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces. When smooth surfaces, like spheres, are represented as parametric surfaces, their surface area can be calculated.
