Step-by-step explanation:
If art takes you longest, you should do it 1st. After do what takes you less, then you will get the harder done 1st, and have something that doesnt take you as long after.
:)
Answer:
You should make yourself a tiny schedule, for example, you can work on your art piece for about an hour and then take a 5 minute break and do some of your other assignments for about 1 hour and 30 minutes. What you can also do is per every hour of working on art you did one other assignment. Hope this helps! :)
The lifespan of zebras in a particular zoo are normally distributed. the average zebra lives 20.5 years the standard deviation is 3.9 years.
use the empirical rule (68-95-99.7%) to estimate the probability of a zebra living less than 32.2 years.
The empirical rule tells us that approximately 99.7% of data in a normal distribution falls within three standard deviations of the mean. The lifespan of 32.2 years is three standard deviations from the mean lifespan of zebras in the zoo, so the probability of a zebra living less than 32.2 years is about 99.7%, which is very high.
To the lifespan of zebras being normally distributed, with a mean of 20.5 years and a standard deviation of 3.9 years.
To estimate the probability of a zebra living less than 32.2 years, we can use the empirical rule, also known as the 68-95-99.7 rule. This rule states that for a normal distribution:
Approximately 68% of the data falls within one standard deviation of the mean (both above and below).
About 95% fall within two standard deviations.
Almost all, or 99.7%, fall within three standard deviations.
To find the probability of a zebra living less than 32.2 years, we first calculate how many standard deviations away from the mean this is, which is called the z-score.
The difference between 32.2 and the mean is 32.2 - 20.5 = 11.7 years.
Dividing this by the standard deviation of 3.9 years, we get a z-score of approximately 3, indicating that 32.2 years is three standard deviations above the mean.
According to the empirical rule, the probability of a zebra living less than 32.2 years would include almost all of the distribution or approximately 99.7%.
Therefore, the probability of a zebra living less than 32.2 years is very high, close to 100%.
Solving systems of equations algebraically.
y = -3x + 4
y= 1
And SHOW YOUR WORK PLEASE!!!!
Answer:
x = 1
y = 1
Step-by-step explanation:
Since it gives you the value of y already, all you need to do is plug it into the equation, like so:
y = -3x + 4
1 = -3x + 4
Now, subtract 4 from both sides:
1 = -3x + 4
-4 - 4
________
-3 = -3x
Finally, divide both sides by -3:
-3 = -3x
1 = x
So now you have, x = 1 and y = 1.

Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds. Which system of equations could be used to find the weight of each animal?
Answer: C
Step-by-step explanation:
First let’s identify that:
y = the kitten
x = the cat
Part 1 : The kitten weighs 3 pounds less than half the weight of Callie's cat.
We know that the kitten is half the size of the cat, which means the equation now looks like this:
x = [tex]\frac{1}{2}[/tex]y
But we also know that the kitten is 3 less than that equation, so now the equation is:
x = [tex]\frac{1}{2}[/tex]y -3
Part 2: Together the cat and the kitten weigh 18 pounds
Now, we have to use the other statement:
y + x = 18
But, that’s not one of the options, so we have to switch the x around and make it negative.
y = -x + 18
These are your answers!
The system of equations could be used to find the weight of each animal is option C.
Calculation of an equation:Since Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds.
Here we assume the kitten be x and cat be y
So, the equation should be

Which expression is represented by the
phrase "the square of y decreased by
quotient of 36 and 6"?
Answer: y^2 - 6
Step-by-step explanation:
We are given the statement which is:
The square of y decreased by the quotient of 36 and 6
We need to get the mathematical expression for the question.
Power 2 is used for square and
The sign "/" is used for quotient or division.
The sign "-" is used to subtract or decrease.
Using the sign above,
Square of y = y^2
Quotient of 36 and 6 = 36/6
The square of y decreased by the quotient of 36 and 6 = y^2 - 36/6
= y^2 - 6
Therefore, the required expression is:
y^2 - 6
The phrase is y^2 - 6.
The phrase "the square of y decreased by the quotient of 36 and 6" translates to the mathematical expression y2 - (36 / 6). This expression involves two operations:
Finding the square of y, which is y multiplied by itself (y2).Calculating the quotient of 36 and 6, which is 36 divided by 6, resulting in 6.Then, you decrease the square of y by this quotient, which gives you the final expression y2 - 6.

s215 - +
SS 25 - 7

O B. (22.5, 2.5)
O c. (25,0)
Answer: (25,0) aka. C
Answer:
c. (25,0)
Step-by-step explanation:
Hope this helps!
The maximum profit is achieved at (25, 0), which means Sal should sell 25 shorts and 0 T-shirts to maximize his profit. So, the answer is (C) (25, 0).
What is profit?Profit is simply the difference between total revenue and total expenses. It shows you how much money your company made after expenses.
Profit, as the primary goal of any business, is a clear indicator of how your company is functioning and performing in the market.
To maximize the profit, we need to use the objective function, which is given by:
P = 14s + 6t
Where s is the number of shorts sold and t is the number of T-shirts sold.
The constraints are:
s + t ≤ 30 (constraint on the total number of items sold)
2s + 5t ≤ 75 (constraint on the amount of shelf space)
The feasible region is the shaded area above.
We can now evaluate the objective function at each corner point of the feasible region to find the maximum profit:
At (0, 20), P = 6(20) = 120
At (7.5, 7.5), P = 14(7.5) + 6(7.5) = 165
At (15, 15), P = 14(15) = 210
At (20, 5), P = 14(20) + 6(5) = 290
At (25, 0), P = 14(25) = 350
Therefore, the answer is (C) (25, 0).

Final answer:
To determine the number of meal combinations, multiply the number of sandwich, soup, and drink options together. With 4 sandwiches, 5 soups, and 3 drinks, there are 60 different meal combinations.
Explanation:
The student's question is asking for the number of different combinations available when choosing one sandwich, one soup, and one drink from a menu with multiple options for each category. To calculate the total number of combinations, we apply the Fundamental Principles of Counting and use the Multiplication Principle. Since there are 4 kinds of sandwiches, 5 kinds of soup, and 3 drinks, the number of unique combinations can be found by multiplying these numbers together.
Number of combinations = Sandwich options × Soup options × Drink options
= 4 × 5 × 3
The calculation gives us 4 × 5 × 3 = 60 different combinations.

x = 10
Step-by-step explanation:
This is because the formula of the area of a triangle is b x h divided by 2.
Since 8 is the base, you have to find what to multiply it by to get 80 (since 80 divided by 2 is the answer, 40).
80 divided by 8 is 10, therefore the base, or x, is 10.
You can put it in the formula to double check and it will equal 40.
Explain when the median of a data set is a better
measure of center than the mean.
Answer:
SAMPLE ANSWER
Step-by-step explanation:
When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.
The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
The median and mean are both measures of central tendency used to describe the center of a data set.
The mean is the sum of all the values in a data set divided by the total number of values, while the median is the middle value when the data set is ordered from least to greatest.
The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.
For example, in a data set where one or a few very large or very small values are present, the mean will be influenced by these values, and will not be representative of the central tendency of the data set as a whole.
In such cases, the median is a more appropriate measure of the center as it is not influenced by outliers and better represents the "typical" value in the data set.
Thus,
When a data set is skewed or contains outliers, the median is a better measure of the center than the mean.

Step-by-step explanation:
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number. From the set {13, 14, 15, 16, 17}, the values of x for which the inequality holds true are .
Answer:
First, you have to simplify the inequality and solve for x.
x + 2x + 6 < 50
3x + 6 < 50
3x < 44
x < 14 2/3
So, you now have another set of numbers, {13, 14, 15, 16, 17}, and you know x must be smaller than 14 2/3. The only two numbers in that set that works are 13 and 14, making A: {13, 14} the correct answer.

Charles plots the point with the polar coordinates (−5,−3π/4). How does he plot this point?
Charles first determines which line the angle of rotation places the point on. This line tells Charles that the point must lie in _____ a if r is positive or ____ if r is negative.
The radius of 5 tells Charles that the point lies on the fifth circle of the polar plane. The value of r is negative. Therefore, the point will lie _____ the angle of rotation.
Answer:
This line tells Charles that the point must lie in Quadrant 3 if r is positive or Quadrant 1 if r is negative.
The value of r is negative. Therefore, the point will lie in the opposite quadrant as the angle of rotation.
Step-by-step explanation:
With polar coordinates the first value represents the distance from the origin and the second value represents the rotation from 0. In this case the distance from the origin value is negative, which means it will be in the opposite quadrant to the angle of rotation.
(-5, −3π/4) results in the same point as (5, π/4)
A rotation of −3π/4 results in the same rotation as 5π/4
The rotation results in Quadrant 3 but because the distance value is negative the final resulting point is in Quadrant 1.
