Nico wants to use a horizontal number line to compare 13 4 and 1. 5. He is unsure how to do it and asks you for help. How would you explain the process?
The order from smallest to largest is 1.5, 4, 13.
To compare numbers using a horizontal number line, simply need to place each number on the line and see which one is farther to the right (greater) or to the left (less).
Here's how to compare 13, 4 and 1.5 on a number line:
Draw a horizontal number line and label it with numbers, making sure to include the numbers you want to compare.Place each number on the line, with the smaller numbers to the left and the larger numbers to the right.Look at the position of each number relative to each other. The numbers farther to the right are greater, while the numbers farther to the left are less.So, in this case, 1.5 is to the left of 4, which is to the left of 13. Therefore, the order from smallest to largest is 1.5, 4, 13.

Step-by-step explanation:
Answer:
63-3-6Step-by-step explanation:
You want the values of x that correspond to y-values of -2, 0, 4, 6, given the relation y = -2/3x +2.
GraphOne way to find the x-values is to read them from a graph of the equation. That is what we have done in the first attachment. This tells us the table is ...
[tex]\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&-2\\3&0\\-3&4\\-6&6\\\cline{1-2}\end{array}[/tex]
Solve for xYou can solve the equation for x, then use that with the given y-values.
y = -2/3x +2
y -2 = -2/3x . . . . . subtract 2
-3/2(y -2) = x . . . . . multiply by -3/2
Using the given y-values, we find the corresponding x-values to be ...
-3/2({-2, 0, 4, 6} -2) = -3/2{-4, -2, 2, 4} = -3{-2, -1, 1, 2} = {6, 3, -3, -6}
These are the values that we obtained from the graph.
For y = {-2, 0, 4, 6}, x = {6, 3, -3, -6}.

the 99% confidence interval estimate for a population variance when a sample standard deviation of 12 is obtained from a sample of 10 items is
This indicates that the population variance is, with 99% confidence, between 8.53 and 9.35.
The chi-square distribution can be used to compute the population variance's 99% confidence interval estimate based on a sample standard deviation of 12 and a sample size of 10.
The confidence interval's formula is:
(s² / X²) * (n - 1) < σ² < (s² / X²) * n
Where X² is the upper percentile of the chi-square distribution with n-1 degrees of freedom, n is the sample size (10), and s² is the sample variance (12² = 144).
Using a chi-square table with 9 degrees of freedom and a 99% level of confidence, we can determine that X² = 16.919 As a result,
the population variance's confidence interval is:
(144 / 16.919) * (10 - 1) < σ² < (144 / 16.919) * 10
(8.53 < σ² < 9.35)
This indicates that the population variance is, with 99% confidence, between 8.53 and 9.35.

how mant ways can a 7 members team be selected out of 9 girls and 5 boys if the members of the team only have only 3 boys
To select a 7-member team consisting of 3 boys and 4 girls out of 9 girls and 5 boys , there are 1260 ways.
To find the number of ways to select a 7-member team consisting of 3 boys and 4 girls out of 9 girls and 5 boys, you can use the formula for combinations:
C(n, k) = n! / (k! * (n - k)!)
where n is the total number of items (9 girls and 5 boys), k is the number of items to be selected (3 boys and 4 girls), and ! represents the factorial function.
So, the number of ways to select 3 boys out of 5 boys is:
C(5, 3) = 5! / (3! * (5 - 3)!) = 5! / (3! * 2!) = 10
And the number of ways to select 4 girls out of 9 girls is:
C(9, 4) = 9! / (4! * (9 - 4)!) = 9! / (4! * 5!) = 126
Finally, the number of ways to select a team of 7 members consisting of 3 boys and 4 girls is:
C(14, 7) = 10 * 126 = 1260
So, there are 1260 ways to select a 7-member team consisting of 3 boys and 4 girls out of 9 girls and 5 boys.

A and B are two similar 2D shapes. The area of shape A is 200cm^2. Calculate the area of shape B.
The area of shape B is 312.5 cm²
Let us assume that the area of the shape B is m square units.
Here, the dimensions of shape A is 12 cm and the area of the shape A is 200 cm²
The dimensions of shape B is 15 cm and the area of the shape B is m cm²
Since A and B are two similar 2D shapes their dimensions must be in proportion.
So, we get an equation,
⇒ A² / B² = 200 / m
⇒ 12² / 15² = 200 / m
⇒ 144 / 225 = 200 / m
⇒ m = (225/144) × 200

A family has a flower garden in the shape of a parallelogram in their backyard. They planted grass in the rest of the yard. What is the area of the backyard that is planted with grass?
Area of the backyard is 9000 sq.ft. Area of the flower garden is 60 sq.ft. So the area of backyard planted with grass will be 8940 sq.ft.
Here the backyard is in rectangular shape and the flower garden is a parallelogram.
Backyard has a length of 120ft and a width of 75ft. Area of a rectangle is given by the equation
Area of rectangle = length× width = 120×75 =9000 sq.ft
Area of backyard = 9000 sq.ft
The flower garden is a parallelogram with base 12 ft and height 5 ft.
Area of a parallelogram = Base× height = 12×5 = 60 sq.ft
Area of flower garden = 60 sq.ft
All the remaining area is planted with grass. So, the area of the portion of backyard planted with grass = Total area of backyard- area of the flower garden.
Area planted with grass = 9000-60 = 8940 sq.ft
So the area of the backyard is 9000 sq.ft, area of the flower garden is 60 sq.ft and area planted with grass is 8940 sq.ft.

O He should report the median.
O He could report either because they are equal.
o The exact number of points per game are needed to

If the player wants to emphasize that his team generally scored a lot of points, it might be best to report the median.
The median and the mean are both measures of center in statistics. They help to describe where the center of the data set is located, but they are not the same thing.
The mean is calculated by adding up all the values in the data set and then dividing by the number of values. It gives a good overall picture of the average of the data set, but it is sensitive to outliers or extreme values.
On the other hand, the median is the middle value in a data set when the values are arranged in order.
To find the median, you must first arrange the values in order and then identify the middle value. If there are an even number of values, the median is the average of the two middle values.
The median is not as sensitive to outliers or extreme values as the mean, so it gives a more accurate picture of the center of the data set when there are outliers or extreme values.

Write the expression that is equivalent to (2x+5)(3x+1)
.
Answer & Step-by-step explanation:
To multiply these two binomials, we can use the distributive property as follows:
(2x+5)(3x+1) = 2x(3x+1) + 5(3x+1)
Now, we can simplify each term:
2x(3x+1) = 6x^2 + 2x
5(3x+1) = 15x + 5
Putting these back together, we get:
(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5
Simplifying the middle two terms, we get:
(2x+5)(3x+1) = 6x^2 + 17x + 5
Therefore, the expression that is equivalent to (2x+5)(3x+1) is 6x^2 + 17x + 5.

An approximate size which does not represent any of the actual dimensions of the unit is nominal value.
The phrase "nominal number" is said to be quite new and rarely used. It seems to have come from the statistical phrase "nominal data," which is reportedly defined as data revealing "...merely declarations of qualitative category of membership," as it is used in school textbooks. The meaning of the word "nominal" in this use is "name."
Nominal numbering is mathematically a one-to-one and onto function from a set of named objects to a set of numbers, which may change (typically growing) over time. It is a function because each named object is assigned a single number; it is one-to-one because different objects are assigned different numbers; and it is onto because every number in the set at a given time has a single named object associated with it.

an urn contains four colored balls: two orange and two blue. two balls are selected at random without replacement, and you are told that at least one of them is orange. what is the probability that both balls are orange?
The probability of drawing two orange balls, given that at least one ball is orange, is 1/5.
There are a total of 6 possible outcomes when selecting 2 balls from the urn without replacement: (O,O), (O,B), (B,O), (B,B), (O,B), (B,O).
The event that at least one of the balls selected is orange corresponds to the outcomes (O,O), (O,B), and (B,O). The probability of this event is the sum of the probabilities of the individual outcomes:
P(at least one orange) = P(O,O) + P(O,B) + P(B,O)
To calculate the individual probabilities, we can use the formula for the number of combinations of n items taken k at a time:
C(n,k) = n! / (k! (n-k)!).
The probability of each outcome is the number of ways it can occur divided by the total number of possible outcomes:
P(O,O) = C(2,2) / C(4,2)
= 2! / (2! (2!)) / (4! / (2! (2!)))
= 1/6
P(O,B) = C(2,1) * C(2,1) / C(4,2)
= 2 * 2! / (1! (2!)) / (4! / (2! (2!)))
= 2/6
P(B,O) = P(O,B) = 2/6
So,
P(at least one orange) = 1/6 + 2/6 + 2/6
=> 5/6
And the probability that both balls are orange is:
P(both orange) = P(O,O) = 1/6.
So, the probability of drawing two orange balls, given that at least one ball is orange, is 1/5.

its Frequency Distribution table
The answer is:
A frequency distribution for a collection of data is shown in the accompanying table.
The intervals or ranges of the data are displayed in the left column of the table, and the frequency or number of observations within each interval is displayed in the right column.
For instance, the first row demonstrates that 4 observations fall within the range of 10 to 19 while the second row demonstrates that 5 observations fall within the range of 20 to 29.
We only combine the frequencies to determine the total number of observations:
Total observations equal 25 (4 + 5 + 8 + 7 + 1 = 25)
By averaging the bottom and upper interval bounds, we can also determine each interval's midpoint. As an illustration, the first interval's midway (10-19) is as follows:
Midpoint: (14.5) (10 + 19) / 2
This may be done for each interval, and to display the midpoints, we can add a third column to the table.
The cumulative frequency, which is the overall frequency as we progress from the shortest interval to the longest interval, can then be calculated. The cumulative frequency can be displayed in the table by using a fourth column.
The finished table is shown here:

The ANOVA for each regression model was conducted to determine whether the overall model is significant. To do this, an F-test was used to compare the sum of squares (SS) of the regression model versus the residual error (RSS). If the F-test is significant, then at least one of the regression parameters is significant and the model is useful for predicting the outcome. In both cases, the F-test was significant which indicates that the regression model is useful for predicting the outcome. The ANOVA also provides information about the individual parameters, such as the p-value associated with each parameter, which can be used to determine which parameters are significant. Overall, this indicates that the regression model is a useful tool for predicting the outcome and can be used to make informed decisions.

Bashir would need to invest $18,900, to the nearest hundred dollars, for the value of the account to reach $29,000 in 19 years.
Describe Investment?Investment refers to the allocation of money or capital to an asset or a project with the expectation of generating a profit or earning an income. Investment can take many forms, including the purchase of stocks, bonds, real estate, or other financial products, as well as the financing of a business or a startup.
Investing involves risk, as the potential return on investment is not guaranteed. Investors must carefully evaluate the potential risks and returns of each investment opportunity before deciding where to allocate their capital.
Investment can be divided into two main categories: short-term and long-term. Short-term investments, such as savings accounts and money market funds, offer relatively low returns but also have lower risk. Long-term investments, such as stocks and real estate, have higher potential returns but also higher risk.
To find the amount that Bashir needs to invest to reach $29,000 in 19 years, we can use the formula for the future value of an investment:
Future Value = Principal * (1 + (Interest Rate ÷ Number of Compounding Periods))^(Number of Compounding Periods x Time in Years)
In this case, the interest rate is 5.7% compounded quarterly, so:
Interest Rate ÷ Number of Compounding Periods = 5.7 ÷ 4 = 1.425%
And the time in years is 19, so the number of compounding periods is 4 * 19 = 76.
Now, we can plug in the values into the formula:
Future Value = Principal * (1 + (1.425 ÷ 100))^(76)
Future Value = Principal * (1.01425)^76
Future Value = 29,000
Solving for Principal, we get:
Principal = 29,000 ÷ (1.01425)^76
Rounding to the nearest hundred dollars, we get:
Principal = $18,900
So, Bashir would need to invest $18,900, to the nearest hundred dollars, for the value of the account to reach $29,000 in 19 years.

Mr. Ross is painting a wall that has an area of 142.5 square feet. He uses
3/4 gallon of paint to paint 1/5 of the wall.
How many gallons of paint will he need to paint the entire wall.
Answer:
Step-by-step explanation:
Say, in relation 3/4 gal of paint : 1/5 of wall. The decimal equivalent is 0.75 : 0.2. With this info., you can multiply 0.2 to get 1 which is equivalent to 1/5 X 5 to get 5/5. What you do to one side, you do to the other, so 0.75 X 5, which gives you 3.75 gal of paint. Round it to 4. So the final answer is 4 gal of paint.
3/4 : 1/5 -> 0.75 : 0.2 -> 5 x 0.75 : 0.2 x 5 -> 5 x 3/4 : 1/5 x 5
15/4 : 5/5 -> 3.75 : 1 = about 4 gals of paint b/c you can't just buy 3.75 gals of paint.
