Answer:
Some
Step-by-step explanation:
Term and expression are two different concepts in mathematics. When numbers, symbols and operators are combined at one place to express or show some value, it is called expression. For example;
4y-3 or 3-1
It is an expression.
Where the term can be stated or defined as a single or smallest identity. Any number or variable or combination of them can be stated as term.
For example, if we take above expression 4y-3
4y-3, we can say that 4y is one term and 3 is second term.
Now the point to be noted here is, if you separately take 4y, it can be expressed as expression as well, because 4y is expressing value of something which is in accordance with the definition of expression.

Oley Scotchgard sells TV's. He earns a 4.5% commission on sales. If his sales last week were $9000, how much did Oley earn?
.
To calculate Oley's earnings based on a 4.5% commission rate from his $9000 sales last week, we need to apply the commission rate to the sales amount.
Here's the calculation we use:
First, convert the percentage to a decimal by dividing by 100. Therefore, 4.5% becomes 0.045.
Next, multiply the sales amount by the decimal commission rate: $9000 × 0.045.
Doing the math gives us Oley's commission: $405.
So, Oley Scotchgard earned a commission of $405 from his sales last week.
Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.
Yes. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is a factor of f(x) = x3 − 75x + 250.
No. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is not a factor of f(x) = x3 − 75x + 250.
Yes. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is not zero. Therefore, x + 10 is a factor of f(x) = x3 − 75x + 250.
No. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is not zero. Therefore, x + 10 is not a factor of f(x) = x3 − 75x + 250.
Answer:
yes, When the function [tex]f(x)=x^3-75x+250[/tex] is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of [tex]f(x)=x^3-75x+250[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=x^3-75x+250[/tex]
We have to find [tex]x+10[/tex] is a factor of given function.
By remainder theorem
[tex]x+10=0[/tex]
[tex]x=-10[/tex]
Substitute x=-10
Then , we get
[tex]f(-10)=(-10)^3-75(-10)+250[/tex]
[tex]f(-10)=-1000+750+250=0[/tex]
Remainder=f(-10)=0
It means x+10 is factor of given function f(x) because when x+10 divides the f(x) then we get remainder=0.
Answer:yes, When the function [tex]f(x)=x^3-75x+250[/tex] is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of [tex]f(x)=x^3-75x+250[/tex]
Eight students on a class treasure hunt found the following number of hidden chocolates. Their teacher wanted to be sure that each student received the same number of chocolates after the event. Which measure(s) of central tendency can the teacher use to distribute the chocolates equally among all of the students?
A. the median B. the mode C. the mean D. either the mean or the mode
The solution is : Option B) Mode is correct
The grade C represent the measure of central tendency is Mode
What is mode?The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
Given that "A teacher writes the results of a test on the board:
7 students received A's, 10 students received B's, 18 students received C's, 4 students received D's, and 1 student received an F."
To find the grade of C would represent which measure of central tendency:
The mode is the most occurring value in a data set.
In the given case, the frequency distribution was 7 A's, 10 B's, 18 C's, 4 D's and 1 F, since C is the most common grade, therefore it is the mode.
Only if the given was a normal distribution, the mode must be equal to the mean and the median.
In this case the median(middle term) is also C .
Hence C is the mode because it is the value that occurs most in the given set of data.
∴ the measure of central tendency for grade C represents is Mode.

b. The house stayed on the market for an average of 250 days before being sold.
c. This is the average number of days the house stayed on the market before being sold for $250,000.
d. The house sold on the market for $250,000 and stayed on the market for an average of 250 days before being sold.
Answer:
C
Step-by-step explanation:
f(p) is the average number of days a house stays on the market before being sold for price p in $1,000s
A little more clearer explanation:
p is the price in $1000s, andf(p) is the number of days before its sold for pHence, f(250) would be the number of days before its sold for 250,000 (since p is in $1000s)
Answer choice C is the correct one.

Step-by-step explanation:
In a sale, normal prices are reduced by 20%. Andrew bought a saddle for his horse in the sale. The sale price of the saddle was £220. Calculate the normal price of the saddle
The normal price of the saddle, x = £275.
To find the normal price of the saddle:
Let the normal price be x.
Since the sale price is £220, which is 80% of the normal price, you can set up the equation: 0.80x = £220.
Solve for x: x = £220 / 0.80 = £275.
Marlye posted a story on her blog. On the first day there were 80 responses and on the second day there were 180 responses. What percent is the increase, 100, of the original number of responses, 80?A . 55% B. 80% C.100% D. 125%
On the second day, the responses to Marlye's blog increased by D. 125%.
Marlye notices that the number of responses to her blog is increasing because 80 responses came in on the first day which increased to 180 responses the next day.
The increase is:
= 180 - 80
= 100 responses
As a percent of the first day, this increase is:
= Increase / Number of responses in day 1 x 100%
= 100 / 80 x 100%
= 1.25 x 100%
= 125%
In conclusion, there was an increase of 125% in the responses to her blog.

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%
The amount of interest that is earned after two years will be $121.8.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
The investment is $2,000 with an interest rate of 3%.
Then the amount of interest that is earned after two years will be given as,
A = 2,000 (1 + 0.03)²
Simplify the expression, then we have
I = $2,000 (1 + 0.03)² - $2,000
I = $2,000 × (1.03)² - $2,000
I = $2,000 × 1.0609 - $2,000
I = $2,121.8 - $2,000
I = $121.8
The amount of interest that is earned after two years will be $121.8.

What is the value of the expression? −4.2 (0.35−3.5)
Final answer:
The value of the expression −4.2 (0.35−3.5) is found by first solving the operation within the parentheses, resulting in −3.15, and then multiplying this result by −4.2 to get 13.23.
Explanation:
To calculate the value of the expression −4.2 (0.35−3.5), we first evaluate the operation inside the parentheses.
0.35 − 3.5 = −3.15
Now, multiply this result by −4.2:
−4.2 × (−3.15) = 13.23
Therefore, the value of the expression −4.2 (0.35−3.5) is 13.23.

it raind during 40% of the days of Chrissys vacation. if it rained on 2 days how many days long was chrissys vacation
To find the length of Chrissy's vacation, use the proportion of rainy days to determine the total number of days, resulting in a 5-day vacation.
Explanation:To find the total number of days in Chrissy's vacation, we can use the fact that it rained on 40% of the days, which is equal to 2 days. From this, we can set up a proportion to solve for the total days. So, if 40% equals 2 days, 100% equals how many days?
Set up a proportion: 40% = 2 days and 100% = x days.Cross multiply: 40 * x = 2 * 100Solve for x: x = (2 * 100) / 40Calculate x: x = 5Therefore, Chrissy's vacation was 5 days long.
