When multiplying decimals, how do you determine where to place the decimal in the answer?
When multiplying decimals, the decimal in the answer is placed based on the total count of digits following decimals in the original numbers. For example, multiplying 0.4 by 0.20 gives 0.08, not just 8.
Explanation:When you're multiplying decimals, the placement of the decimal in the answer is determined by the total number of digits behind the decimals in the problems you're multiplying. For example, if you're multiplying 0.4 (one digit after the decimal) by 0.20 (two digits after the decimal), your answer should have three digits after it. So, let's multiply: 4 times 2 equals 8, but this should be written as 0.08, not just 8, due to the rule. That's how you manage the decimal placement when multiplying decimals.

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]

How to find lowest common multiple of numbers?!?
To find the LCM of numbers, identify the prime factors, and multiply the highest power of each prime factor together.
Explanation:To find the lowest common multiple (LCM) of numbers, you need to identify the prime factors of each number and then multiply the highest power of each prime factor together. Here's an example:
Let's find the LCM of 6 and 9:
Prime factors of 6: 2 x 3 x 3Prime factors of 9: 3 x 3Highest power of 2: 2Highest power of 3: 3LCM of 6 and 9: 2 x 3 x 3 = 18So, the LCM of 6 and 9 is 18.

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.

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.

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.

Feathers is ready to show off a coin trick. What is the probability of flipping heads on a coin and then flipping the coin again and getting heads?
The probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.
Explanation:To find the probability of flipping heads on a coin and then flipping the coin again and getting heads, we need to multiply the probabilities of each event. The probability of flipping heads on a fair coin is 0.5. Since each flip of the coin is independent, we can multiply the probabilities together: 0.5 * 0.5 = 0.25. Therefore, the probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.

Candice uses a total of 6 hangers for her six pairs of jeans, with one hanger used for each pair of jeans.
Explanation:The question is asking to calculate the number of hangers Candice would use if she places each pair of her six pairs of jeans on its own hanger. Since Candice is placing each pair of jeans on a separate hanger, we can easily determine the answer by understanding the one-to-one relationship between pairs of jeans and hangers.
For each pair of jeans, Candice uses one hanger. Therefore, the calculation is straightforward as we simply multiply the number of pairs of jeans by the number of hangers used per pair of jeans, which is one.
Number of jeans pairs: 6Number of hangers used per pair: 1Total number of hangers used: 6 pairs × 1 hanger per pair = 6 hangersIn conclusion, Candice uses 6 hangers to hang her six pairs of jeans.
Maria bought 1/4 pound of ham and 5/8 pound of turkey. How much more turkey than ham did she buy?
Maria bought 1/4 pound more turkey than ham by calculating the difference between 5/8 pound of turkey and 1/4 pound of ham.
Explanation:To determine how much more turkey than ham Maria bought, we need to compare the weights of the turkey and the ham. Maria bought 1/4 pound of ham and 5/8 pound of turkey. To find the difference, we subtract the smaller quantity (ham) from the larger quantity (turkey).
First, we need both quantities in the same unit. They are both already in pounds, so we can subtract directly:
5/8 pound (turkey) - 1/4 pound (ham) = 2/8 pound (or 1/4 pound)
Maria bought 1/4 pound more turkey than ham.

The ratio of cereal boxes with prizes to without prizes in this scenario is 1:7, which is option A. This is calculated by dividing the number of boxes with and without prizes by the smallest number (3), resulting in the simplified ratio.
Explanation:The subject of this question is about understanding mathematical ratios, specifically in the context of a cereal box prize scenario. Here, we are asked to find the ratio of boxes with prizes to boxes without prizes. If 3 out of 24 boxes contain a prize, that means 21 boxes are without a prize.
To find the ratio of boxes with prizes to boxes without prizes, we divide both numbers by the smallest one, which is 3, the number of boxes with prizes. Hence, the ratio is 3:21, which simplifies to 1:7 (since both numbers are divisible by 3). Therefore, the answer to this question is Option A, 1:7.
