Evaluate the expression 5m – 6 for m = 7. 29 41 5 51
When m = 7, the expression 5m - 6 evaluates to 29.
To evaluate the expression 5m - 6 for m = 7, we substitute m with 7:
5m - 6 = 5(7) - 6
Next, we perform the multiplication first:
5(7) = 35
Now we can substitute the value into the expression:
5m - 6 = 35 - 6
Finally, we perform the subtraction:
35 - 6 = 29
Therefore, when m = 7, the expression 5m - 6 evaluates to 29.

convert a 30% markup percent on cost to markup percent on selling price. (round to the nearest hundredth percent)
Answer:
23.08 %
Step-by-step explanation:
Markup price is the difference between the selling price and cost price of an item.
m = Markup = 30
s = Selling price = 130
[tex]\text{Markup percent on selling price}=\frac{m}{s}\times 100\\\Rightarrow \text{Markup percent on selling price}=\frac{30}{130}\times 100\\\Rightarrow \text{Markup percent on selling price}=23.08\ %[/tex]
∴ Markup percent on selling price is 23.08 %
Esther wants to know if the number of words on a page in her language arts book is generally more than the number of words on a page in her social studies book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Language arts 78.5 60 14.2
Social studies 68.7 65 9.8
She claims that because the mean number of words on each page of the language arts book is greater than the mean number of words on each page of the social studies book, the language arts book has more words per page. Based on the data, is this a valid inference?
Yes, because there is a lot of variability in the language arts book data
No, because there is a lot of variability in the language arts book data
Yes, because the mean is larger in the language arts book
No, because the mean is larger in the social studies book
The correct choice is, No, because there is a lot of variability in the language arts book data.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
From the given data, it is clear that the mean number of pages of language arts book is greater than that of social studies book.
However, the mean absolute deviation is greater for language arts book and median is lower for language arts book.
This clears the fact that the variability is high for language arts book. So the number of pages could actually be less than that in social studies book.
Hence the correct option is that we cannot say a valid inference because there is a lot of variability in the language arts book data.

The tax rate on Jerome James 112000 vacation home is 25 Mills the property is assessed at full value how much will Jerome pay in taxes this year
Answer: $2,800
Step-by-step explanation:
Given: The assessment value of Jerome's home= [tex]$112,000[/tex]
We know that to calculate the property tax, we need to multiply the assessment value of the property by the mill rate and then divide by 1,000.
Then, the property tax is given by :-
[tex]\text{Property tax}=\dfrac{\$112,000\times25}{100}\\\\\Rightarrow=\text{Property tax}=\$2,800[/tex]
Therefore, Jerome pay $2,800 as property tax in this year.
Answer:
[tex]Property tax=$2800[/tex]
Step-by-step explanation:
Given: The assessment value of Jerome's home is given as =[tex]112000[/tex]
Solution: Since we know that in order to calculate the property tax, we need to multiply the assessment value of the property by the mill rate and also divide by [tex]1000[/tex].
Then, the property tax is given as :-
[tex]Property tax=\frac{112000{\times}25}{100}[/tex]
[tex]Property tax=$2800[/tex]
Thus, Jerome pay $2,800 as property tax in this year.
what point is on the graph of every direct variation equation
In a direct variation equation, the graph passes through the origin (0,0). Every point on the graph can be represented as (kx, ky), where k is a constant.
Explanation:In a direct variation equation, the graph passes through the origin (0,0). This means that when x=0, y=0. Every point on the graph can be represented as (kx, ky), where k is a constant. For example, if the direct variation equation is y = 2x, the graph would pass through (0,0), (1,2), (2,4), (3,6), and so on.

A wall in Marcus's bedroom is feet high and feet long. If he paints of the wall blue, how many square feet will be blue?
To find the square footage of a wall painted blue, you would first calculate the total size of the wall by multiplying the wall's height and length. Then, you would multiply this number by the proportion of the wall you plan to paint blue. This will give you the number of square feet that will be coloured blue.
Explanation:This question pertains to the mathematical concept of resolving problems involving areas and percentages. Marcus's wall's total area can be calculated by multiplying the wall's length and height. However, since the measurements have not been provided in the question, let's assume their values to be 'L' and 'H' feet respectively. The area of the wall would then be simply H*L square feet.
Now, if Marcus decides to cover a certain percentage of this wall with blue paint, we must determine the total square feet being painted. If the proportion of the wall to be painted is 'P', the blue-painted area is given by H*L*P (P being a decimal representation of the given percent, i.e., 20% would be represented as 0.20).
Therefore, the number of square feet that will be blue is the product of the total wall area and the proportion to be painted blue.

complete a table for the rule y = x2 + 2. Use negative and positive values and 0 for x
Table:
| x | y = x^2 + 2 |

let's complete a table for the rule [tex]\( y = x^2 + 2 \)[/tex] by plugging in various values of [tex]\( x \)[/tex], including negative, positive, and zero, and then calculating the corresponding values of [tex]\( y \)[/tex] .
Given the rule [tex]\( y = x^2 + 2 \)[/tex], we'll substitute different values of [tex]\( x \)[/tex] into the equation and solve for [tex]\( y \)[/tex]. Here's a step-by-step process:
1. Choose values for [tex]\( x \)[/tex]. Let's pick a range of values, including negative, positive, and zero, to get a good representation of the function.
2. Substitute each chosen value of [tex]\( x \)[/tex] into the equation [tex]\( y = x^2 + 2 \)[/tex].
3. Calculate the corresponding value of [tex]\( y \)[/tex] by performing the arithmetic operations.
4. Record the pairs of [tex]\( x \)[/tex] and [tex]\( y \)[/tex] values in a table.
Here's the completed table:
| [tex]\( x \) | \( y = x^2 + 2 \)[/tex] |
|---------|-----------------|
