Answer:
4.25c + 3.5p = 36.50
c + 6 = p
c = candies and p = pretzels
Step-by-step explanation:
So for the first equation, the prices will be the coefficients of each variable, since for each candy/pretzel it will be that price. We also know that both of these prices together equal 36.50, so that will be on the other side of the equal sign. So the equation representing this info is 4.25c + 3.5p = 36.50
And for the second equation I saw that Mason bought 6 more pretzels than candies. So no matter what number the candies is, the pretzels should always be 6 more than the candies. So the equation representing this information is c + 6 = p
Lastly I just defined the variables that I used to right the system. That is all! Hope this helps you this should be correct :)

Aaron Rodgers' yearly salary is 2.2 x 10' dollars. The yearly salary of one of his backup
quarterback's is 6.3x105 dollars. How many times greater is Aaron Rodgers' salary than his
backup's salary?
Aaron Rodgers salary is 2.19×[tex]10^1^1[/tex] greater than his backups.
To find how many times a quantity x is greater than y we do subtraction. That is we do [tex]x-y[/tex].
So, here Aaron's salary is given to be $ 2.2× [tex]10^1^0[/tex]
And his quarterback's salary is $ 6.3×[tex]10^5[/tex].
Thus the difference between salaries= 2.2×[tex]10^1^0[/tex] - 6.3 × [tex]10^5[/tex]
= 2.19×[tex]10^1^1[/tex]

The inverse of the conditional statement is : if two lines do not intersect, then the lines are not coplanar.
Conditionals are commands used in programming languages to handle decisions.
Conditional statements are those that have both a hypothesis and a conclusion. It is also known as a "If-then" statement. If the conclusion and the hypothesis are both true, the conditional statement is untrue.They include conditional statements, conditional expressions, and conditional constructions. Particularly, conditionals carry out various calculations or actions according on whether a boolean condition set by the programmer evaluates to true or false. The decision is always made in terms of control flow by selecting changing the control flow based on some situation.The contrapositive statement is : If two lines are not coplanar, then the lines do not intersect.
The converse statement is : If two lines are coplanar, then the lines intersect.

SOMEONE HELP! I NEED THIS QUICKLY! WILLING TO GIVE 45 POINTS!!! At 1 P.M., the total snowfall is 2 centimeters. At 4 P.M., the total snowfall is 7 centimeters. What is the mean hourly snowfall? Write your answer in simplest form as a fraction or mixed number.
The mean hourly snowfall is (5/3) centimeters per hour, which means that each hour there are 5/3 centimeters more of snow.
What is the mean hourly snowfall?The mean hourly snowfall is given by the quotient between difference between the total snowfall at the two given times and the total time.
Here we have:
Initial snowfall = 2cm
Final snowfall = 7cm
Difference = 7cm - 2cm = 5cm
And that happens between 1 P.M. and 4 P.M., so we have 3 hours.
Then the mean hourly snowfall is:
M = 5cm/3h = (5/3) centimeters per hour.

find the common difference of thr arithmetic sequence -19 -14 -9
-5 is the common difference of the arithmetic sequence.
What is arithmetic sequence?A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15. The nth term of an arithmetic progression is determined using the arithmetic sequence formula. The series where the common difference between any two next words stays constant is known as an arithmetic sequence.
Given Data
Arithmetic sequence
-19, -14, -9
Common difference = a₂ - a₁
Common difference = -14 - (-19)
Common difference = -14 + 19
Common difference = -5

Samuel was absent for the last biology test. For those who took the test, the mean was 84.6, the median was 82, and the mode was 88. When Samuel took the test, the class mean went down to exactly 84. His score was different from every other students’ score. What effect, if any, did Samuel’s score have on the class mode?
A: None; the mode stayed the same.
B: It decreased the mode by exactly 1 point.
C: It increased the mode by exactly 1 point.
D: It increased the mode by greater than 1 point.
E: The effect of Samuel’s score on the mode cannot be determined from the given information.
The correct option is A: None; the mode stayed the same.
What is Mode?Mode of a data set is the value that occur most frequently in a data set.
There may be no mode, one mode or more than one mode for a data depending on the number of times values are repeating.
Given that before Samuel taking a test,
Mean = 84.6
Median = 82
Mode = 88
After Samuel took the test,
Mean = 84
Also given that, his score was different from every other students’ score.
This means that from the data of scores, Samuel's score is not repeating.
Mode is the most repeating element.
So Samuel's score does not effect the mode and thus stayed the same.
Hence the mode stayed the same.

C. 2x² - x + 2
D. 4x²+x-8
Answer:
B 2x² - x - 2

I have one fair 6-sided die and one unfair 6-sided die. On the unfair die, the probabilities of rolling numbers 2,…,6 are equal and the probability of rolling a 1 has a different value. I roll each die once.
If the probability of rolling one 3 and one 4 is 1/24, what is the probability of rolling two 1’s?
Answer:
[tex]\dfrac{1}{16}[/tex]
Step-by-step explanation:
Probability Distribution Table for X
Where X is the score on a fair, six-sided dice:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} x & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(X=x) \phantom{\dfrac11}&\frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} \\\cline{1-7}\end{array}[/tex]
Probability Distribution Table for Y
Where Y is the score on an unfair, six-sided dice, and the probabilities of rolling numbers 2, 3, 4, 5 and 6 are equal, and the probability of rolling a 1 has a different value:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} y & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(Y=y) \phantom{\dfrac11}&1-5k&k&k&k&k&k\\\cline{1-7}\end{array}[/tex]
Note: The probabilities of all the possible values that a discrete random variable can take add up to 1.
The outcomes of rolling one 3 and one 4 are:
Rolling a 3 with the first die and a 4 with the second die, ORRolling a 4 with the first die and a 3 with the second die.Given the probability of rolling one 3 and one 4 is ¹/₂₄:
[tex]\implies \text{P}(X=3)\; \text{and} \; \text{P}(Y=4) \; \text{or} \; \; \text{P}(X=4) \; \; \text{and} \; \; \text{P}(Y=3)=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{1}{6} \times k +\dfrac{1}{6} \times k=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{k}{6} + \dfrac{k}{6}=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{2k}{6}=\dfrac{1}{24}[/tex]
[tex]\implies 24(2k)=6[/tex]
[tex]\implies 48k=6[/tex]
[tex]\implies k=\dfrac{1}{8}[/tex]
Therefore:
[tex]\implies 1-5k=1-\dfrac{5}{8}=\dfrac{3}{8}[/tex]
Hence, the probability distribution table for the unfair 6-sided dice is:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} y & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(Y=y) \phantom{\dfrac11}&\frac{3}{8} & \frac{1}{8} & \frac{1}{8}& \frac{1}{8} & \frac{1}{8}& \frac{1}{8} \\\cline{1-7}\end{array}[/tex]
There is only one possible outcome of rolling two 1's, so the probability of rolling two 1's is:
[tex]\implies \text{P$(X=1)$ and P$(Y=1)$}=\dfrac{1}{6}\times\dfrac{3}{8}=\dfrac{3}{48}=\dfrac{1}{16}[/tex]
Note: Please see attachment for the sample-space diagram showing the possible outcomes of rolling two dice. The possible outcomes of rolling one 3 and one 4 are highlighted in yellow. The possible outcome of rolling two 1's is highlighted in blue.

Both items in this problem are represented by direct proportional relationships, we just have to identify the constants then graph the relations.
For item 1, the constant is of 3, as the perimeter is of three times the side length of the triangle.For item 2, the constant is of 1/3, as a division by 3 is equivalent to a multiplication by 1/3.The graph of a proportional relationship is linear with slope given by the constant and intercept at 0, hence the graphs for each item are given at the end of the answer.
