The cost of a given number of handbags - Discrete

Amount of juice in a jug over time - Continuous

Area of a field based on length - Continuous

Tires in a number of cars -Discrete

A discrete function as its name suggests has distinct or separate values against one value. That is, one at a time values are in a discrete function. So its domain and image sets will have discrete values.

A continuous function has continuous values within intervals. Its domain will be intervals having a continuous range and images will also be in a  continuous range.

We need to check if the following will have a discrete or a continuous graph:

1. The cost of a given number of handbags.

This is a discrete function as the cost and number of handbags will have discrete values. So it will have a discrete graph.

2. Amount of juice in a jug over time

This is a continuous function. The variables here are the amount of juice and time in which time, clearly, is a continuous variable. So it will have continuous values in an interval. So the amount of juice can also be measured continuously. So the graph will be continuous.

3.  Area of a field based on length

Here the length can take continuous values in an interval. So the area can also be measured continuously giving a continuous graph here.

4. Tires in a number of cars.

Number of tires and number of cars both will take only discrete values. So it can only give a discrete graph.

Answer:

22

Step-by-step explanation:

By the segment addition postulate, FH=8+14=22.

The equation will be,

→ FH = FG + GH

Then the value of FH will be,

→ FH = 8 + 14

→ [ FH = 22 ]

Hence, the value of FH is 22.

The slope of the line shown is -2/3

The formula for calculating the slope of a line is expressed according to the formula

Slope = Rise/Run

Slope = y₂-y₁/x₂-x₁

Using the coordinate point (-9,-2) and (-6, -4)

Slope = -4+2/-6+9
Slope = -2/3

Slope = negative two third

Probability of an even number product as requested = 7/10 = .7 = 70%

The probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

Combinations of 2 digits from among 5 = 5!/(3!)(2!) = 10. Those combinations of 2 digits resulting in an even number product are even*even and even*odd. There are 2 even digits, (2,4), and 3 odd digits, (1,3,5).

Combinations of 2 even digits and 3 odd digits = 3*2 = 6. Combinations of 2 even digits = 1*1 = 1. there are thus 6+1 = 7 distinct 2 digit products that result in even numbers from among 10 possible 2 digit products.

Probability of an even number product as requested = 7/10 = .7 = 70%

The equation to find the number of players the team can bring to the tournament is xx = ( 2,143.50 - 888.50 )/62.75 and the number of players the team can bring to the tournament is 20.

An equation is a mathematical statement that shows that two or more mathematical expressions are equal.

Equations express the equality of mathematical expressions by using the equation mark (=).

The total amount raised for the tournament is $2,143.50

The price to rent a bus is $888.50.

The cost of budgeted meals per player is $62.75.

The number of players the team can bring to the tournament is:

xx = ( 2,143.50 - 888.50 ) / 62.75.

xx = ( 2,143.50 - 888.50 ) / 62.75

xx = 1,255 / 62.75

xx = 20

Therefore, the equation to calculate the maximum number of players the team can enter the competition is xx = ( 2,143.50 - 888.50 ) / 62.75.

The two different species of plants will take 5 years to reach the same height.

Given, from the table :

Tree specie A has a:

current height = 38 inches

and its annual growth = 4 inches

Therefore, total height is:

38 + 4x .. eq (1)

Tree specie B has a:

current height = 45.5 inches

and its annual growth = 2.5 inches

Therefore, total height is:

45.5 + 2.5x .. eq (2)

Equate equation 1 and equation 2.

38 + 4x = 45.5 + 2.5x

Subtract the constants.

4x = 45.5 - 38 + 2.5x

4x = 7.5 + 2.5x

now subtract the variables.

4x - 2.5x = 7.5

1.5x = 7.5

x = 7.5/1.5

x = 5

Hence the trees will take 5 years to reach the same height.

125 is greater than 23.

Given the question is to explain 125 > 23.

Here we have two numbers which are 125 and 23.

Inequalities:

Whenever we check the number which is greater or lesser by taking the difference between those two numbers we conclude which is greater or lesser.

If the difference between the numbers gets a positive number then the first number is greater than the second.

If the difference between the numbers gets a negative number then the first number is lesser than the second.

If the difference between the numbers gets zero value then the two numbers are equal.

So the difference between the given two numbers are

Answer:

3.14159

Step-by-step explanation:

The value of π correct to 5 decimal places is 3.14159.

Decimal numbers are numbers which includes a whole number part and a fractional part.

The point separating both parts is the decimal point.

Pi, which is written as the Greek symbol π, is defined as the ratio of the circumference of any circle to the diameter of that circle.

We know that,

Circumference of a circle, C = 2 π r, where r is the radius.

2r will be the diameter.

π = C / 2r

The value of pi to 5 decimal places = 3.14159

Normally we use 3.14.

Hence the value of pi is 3.14159 to 5 decimal places.

Step-by-step explanation:

Find out how many times an element(data value) appears. That will be the frequency(column 2). The cumulative frequency is the total of all frequencies prior to that element plus the current element frequency

Cumulative frequency for first element is same as its frequency

Cumulative frequency for element 16 is 3 + 6 = 9

Cumulative frequency for element 17 = 3 + 6 + 1 = 9 + 1=10. Basically it is the sum of the previous element cumulative frequency + the current frequency

The equation of line that passes through the given points in  point-slope form is y - 2 = -4/3( x - 4 ).

Given the data in the question;

Point A(4, 2)

Point B(1, 6)

First, we determine the slope of the line.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 6 - 2 )/( 1 - 4 )

Slope m = ( 4 )/( -3)

Slope m = -4/3

Next, plug the slope -4/3 and point (4,2) into the point slope formula y - y₁ = m( x - x₁ ) and simplify.

y - y₁ = m( x - x₁ )

y - 2 = -4/3( x - 4 )

Therefore, the equation of line that passes through the given points in  point-slope form is y - 2 = -4/3( x - 4 ).

Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.

As we know, corresponding angles are congruent.

So, ∠6= ∠2

⇒ 9x+13=11x-3

⇒ 13+3=11x-9x
