Answer:
3/8
Step-by-step explanation:
The expression can be rewritten as b + 1/8 + c
substitute b and c
2 + 1/8 - 7/4 = 16/8 + 1/8 - 14/8 = 3/8
Answer:
3/8
Step-by-step explanation:
b - (-1/8) +c
Subtracting a negative is adding
b+1/8+c
Let b =2 and c = -7/4
2+1/8 - 7/4
2 1/8 - 7/4
Getting a common denominator
2 1/8 - 7/4*2/2
2 1/8 - 14/8
Changing to an improper fraction
17/8 - 14/8
3/8

can someone simplify 423/16 for me
(show work)
Answers
Step-by-step explanation:
1. Find the GCD (or HCF) of numerator and denominator
GCD of 423 and 16 is 1.
2. Divide both the numerator and denominator by the GCD
423 ÷ 1= 323
16 ÷ 1=16
3. Reduced fraction:
423
16
Therefore, 423/16 simplified to lowest terms is 423/16.
Answer: 423/16
Step-by-step explanation:
To be able to simplify 423/16, we need to find their greatest common factor (GCF). This is much easier to do using the smaller number, as it has less factors most of the time.
The factors of 16 are: 1, 2, 4, 8, 16.
If 423 shares one of these factors, we can simplify 423/16.
Since 2, 4, 8, and 16 are even numbers and 423 is odd, we already know that those are not factors of 423.
So, the only factor of 16 left that 423 shares is 1. If you divide 423/1 and 16/1, the fraction still is 423/16. This means that 423/16 is already in its simplest form.
If you want to find the decimal form of 423/16, it is 26.4375. 16 x 26 = 416. 416 + 16 = 432, which is greater than 423.
This means that 16 goes into 423 twenty-six times before it cannot fully go into it anymore.

yellow would be B
orange would be D
I hope this helps!!!!
Answer:
a) point B
b) point D
Step-by-step explanation:
a) since there are 3 yellow sweets out of a total of ten, the probability of choosing a yellow sweet is 3/10 = 0.3 Therefore point B shows that number on the probability scale.
b) Since there are no orange sweets in the bag, the chances of a selecting sweet not being orange is ten out of ten (10/10 = 1 (for sure the sweet will not be orange). Therefore, point D shows such probability.

Answer:
x^5(1+x)(1-x+x^2)
Step-by-step explanation:
b^5 +b^8 =
You can easily solve this equation by doing factoring (a fancy word for dividing)
so, factor out the Greatest Common Factor (GCF)
which is
B^5
so in parenthesis write (1+b^3) next to it, think of subtracting the two exponents, and then since theres only 1 thing left after factoring out b^5, you leave a 1 behind.
b^5(1+b^3)
from here, in the parenthesis, you have 2 perfect cubes, 1 and b^3
take the cube root of that which is (1+b)
then use (a+b) which is already done
AND (a^2-ab+b^2) where a is equal to 1, and b is equal to variable b.
so, that would be
x^5(1+x)(1-1x+x^2) ( this is what you should get once you do multiply the square root out to just get constants and coefficients.
That gives us our final answer of x^5(1+x)(1-1x+x^2) because it is in the simplest form possible.

Cinderella made many new friends at the castle. After asking her fairy godmother to help, she invited her friends to go on a picnic. There were 36 heads and 104 legs in the group of horses, carriages, and riders. How many horses and how many people were there?
Answers
Answer:
104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Forty-five students were surveyed about what their favorite sport is. Ten said Hockey was their favorite. There are 414 students total. Based on this, estimate how many of the 414 students would favor Hockey?
Answers
10/45 = x/414
where x is the estimated number of students who favor Hockey out of the total 414 students.
To solve for x, we can cross-multiply:
10 * 414 = 45 * x
4,140 = 45x
x ≈ 92
Therefore, we can estimate that around 92 out of the 414 students would favor Hockey.
