Answer:

1.666......

( 1.6 recurring).

Step-by-step explanation:

As both numbers are multiples of 10 it makes it a bit easier to divide both by 10 to give 25 and 15. This will give the same result as 250/150.

Now do a long division , 25 divided by 15:

        1 .66                    <-----------  25 / 15 = 1 .  1*15 goes below the 25.

    -------------------------

15 ) 25.0

       15      <---------- subtract 25 - 15 = 10

        100 <- bring down the zero(after the decimal point) & append to 10

          90 <  15 divides into 100 6 times to give 90 . Place 6 above line.

           100   < subtract 100 - 90 to give 10 then add 0

             90 < as before 100/15 = 6  to give 6*15 = 90

If you carry on as above you'll see that we get 1.6666...  and we could go on for ever. This is a recurring decimal and is usually written as 1.6 with a bar above the 6.

Answer:

14 and 16.

Step-by-step explanation:

We know that two consecutive even numbers is 30.

Let's let n be any number.

Then the first even number must be 2n.

This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.

Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.

We know that they sum to 30. So, we can write the following equation.

\((2n)+(2n+2)=30\)

And we solve from there:

\(4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7\)

So, the value of n is 7.

Therefore, the first even number is 7(2)=14.

And the consecutive even number is 16.

Find the slope between the two points given. Then, use the slope and point ONE to write the

equation of the

The evaluation the city's population, to find the (average) rate of change of the population is presented as follows;

The average rate of change of the city population between 1930 and 1950 is 0.25 thousands per year

2. a. Positive

b. Negative

c. Negative

3. The population grew fastest in the decade between 1910-1920

The average rate of change of a function within an interval, is an indication of change of the function per unit change within the interval.

The city population in 1930 = 40 thousand

The population of the city in 1950 = 45 thousand

The average rate of change of the population between 1930 and 1950 therefore is;

Average rate of change = (45 - 40)/(1950 - 1930) = 0.25

The population increases at an average rate of 0.25 thousand persons per year between 1930 and 1950

2. The rate of change of the population between two years is positive, where the line joining the the two years increases from left to right and the rate of change is negative where the line decreases from left to right

a. The line joining the points 1930 and 1940 on the graph increases from left to right, therefore;

b. The location of the point on the graph in 1950 is the highest point while the location of the point on the graph corresponding to the year 1970 is lower, therefore, the line joining the points on the graph decreases from left to right and therefore;

c. 1930 corresponds to a population of 40 thousand, while 1970 corresponds to a population of 35 thousand, therefore, a line extending from 40,000 (1930) to 35,000 (1970), decreases from left to right and therefore;

3. The population growth between 1900 and 1910 is from 20 thousand to 25,000; A growth of 5 thousand

The population growth between 1910 and 1920 is from 25 thousand to 35 thousand; Representing a growth of 10 thousand

The population growth between 1920 and 1930 is from 35,000 to 40,000; A growth of 5 thousand

The change in the population between 1930 and 1940 ≈ 44,000 - 40,000 = 4,000

The change in the population between 1940 and 1950 = 45,000 - 44,000 = 1,000

Therefore, the population grew fastest between 1910 and 1920, with a growth of 10,000 in 10 years or 1,000 per year

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

The selection can be made in 15 different ways, taking into account the distinct combinations of a boy and a girl from the given group of 5 boys and 3 girls.

To determine the number of ways a boy and a girl can be selected from a group of 5 boys and 3 girls to attend a conference, we can use the concept of combinations.

The number of ways to choose one boy from 5 boys is 5C1, which is equal to 5. Similarly, the number of ways to choose one girl from 3 girls is 3C1, which is equal to 3.

To select one boy and one girl, we need to multiply the number of ways to choose a boy and a girl together. Using the multiplication principle, we multiply the number of choices for each category: 5C1 * 3C1 = 5 * 3 = 15.

Therefore, there are 15 ways to select a boy and a girl from the given group to attend the conference.

Each combination represents a unique pair consisting of one boy and one girl. For example, if the boys are labeled as B1, B2, B3, B4, and B5, and the girls are labeled as G1, G2, and G3, the possible pairs could be (B1, G1), (B1, G2), (B1, G3), (B2, G1), (B2, G2), and so on, up to (B5, G3).

Answer: D

Step-by-step explanation:

To determine which ordered pair is a solution to the inequality, we can substitute the values of x and y into the inequality and check if it is true.

Let's start with ordered pair A (80, 6):

1/4x ≤ 7/3y + 2

1/4(80) ≤ 7/3(6) + 2

20 ≤ 14 + 2

20 ≤ 16

This is not true, so ordered pair A is not a solution to the inequality.

Now let's try ordered pair B (48, 9):

1/4x ≤ 7/3y + 2

1/4(48) ≤ 7/3(9) + 2

12 ≤ 21 + 2

12 ≤ 23

This is also not true, so ordered pair B is not a solution to the inequality.

Next, let's try ordered pair C (40, 3):

1/4x ≤ 7/3y + 2

1/4(40) ≤ 7/3(3) + 2

10 ≤ 7 + 2

10 ≤ 9

This is false, so option C is not a solution to the inequality.

Finally, we have option D: (2, -6)

1/4(2) ≤ 7/3(-6) + 2

1/2 ≤ -14 + 2

1/2 ≤ -12

This is true, so option D is a solution to the inequality.

Therefore, the answer is D: (2, -6).

The area of the square with a side length of 3.1 meters is 9.61 square meters.

To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.

Area of a square = side length × side length

Substituting the given side length into the formula:

Area = 3.1 m × 3.1 m

To perform the calculation:

Area = 9.61 m²

It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.

Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

The area of the square with a side length of 3.1 meters is 9.61 square meters.

Answer:

The median, mean, and mode of the data set are 2, 1.9, and 1.

Step-by-step explanation:

To find the median of a data set, line up all values from greatest to least and find the number in the center. For example, in the set 1, 2, 3, 2 would be the median. In this case, the order would be 1, 1, 1, 1, 2, 2, 2, 3, 3, 3. The two numbers in the middle are 2 and 2, their average is 2, so that would be the median. The mean of a data set is the average of all data values in a set. In this case, there are 10 data values, and their total sum is 19, so the mean of this data set is 1.9. The mode of a data set is the value that occurs the most in a set. In this case, 1 occurs four times, 2 occurs three times, and 3 occurs three times, so the mode of this data set is 1.

Answer:

Mode: 1

Mean: 1.9

Range: 2

Step-by-step explanation:

Mode: the number that occurs more often

Mean: To find the mean, add all the numbers together then divide by the number of numbers.

Range: is the difference between the largest and the smallest value.

--------------------------------------------------------------------------------------------------------------

Mode: 1,1,1,1,2,2,2,3,3,3. 1 is mostly being occurred so 1 is the mode.

Mean: 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 = 19 divided by 10 equals 1.9.

Range: the largest number is 3. The smallest number is 1. 3 - 1 = 2

Answer:

what you would do is 23.89x18%=4.3 so you do 23.89-4.3=19.59 then you do 19.59x7%=1.37 then you do 19.59+1.37=20.96 so 20.96 is your answer.

Step-by-step explanation:

Answer: To calculate the final price that Lin's father pays for the meal, we need to apply the discount first and then add the sales tax.

Discount = 18% of $23.89

= 0.18 x $23.89

= $4.30

The discounted price of the meal is therefore:

$23.89 - $4.30 = $19.59

Next, we need to add the sales tax of 7%:

Sales Tax = 7% of $19.59

= 0.07 x $19.59

= $1.37

Therefore, the final price that Lin's father pays for the meal is:

$19.59 + $1.37 = $20.96

So, Lin's father pays $20.96 for the meal after applying the discount and sales tax.

Step-by-step explanation:

There are six possible outcomes when rolling a fair six-sided die: 1, 2, 3, 4, 5, or 6. Three of these outcomes are 2, 4, or 5, so to find the probability of getting anything other than a 2, 4, or 5, we need to count the number of outcomes that are not 2, 4, or 5.

There are three outcomes that are 2, 4, or 5, so there are six - three = three outcomes that are not 2, 4, or 5. Therefore, the probability of getting anything other than a 2, 4, or 5 when rolling one die is:

P(anything other than 2, 4, or 5) = 3/6 = 1/2 = 0.5

So the probability of getting anything other than a 2, 4, or 5 is 0.5 or 50%.
