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.
Answers
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.

How many non-identical triangles can be made using these side lengths:

Answers
By applying the Triangle Inequality Theorem, the number of non-identical triangles that can be made using the given side lengths is one.
What is the Triangle Inequality Theorem?In Mathematics, the Triangle Inequality Theorem can be defined as a type of theorem which states that the sum of any two (2) side lengths of a triangle must be greater than the measure of the third (2) side.
This ultimately implies that, the sum of the lengths of any two (2) sides of a triangle cannot be less than the length of the third (3) side of the triangle in accordance with the Triangle Inequality Theorem, as represented by this mathematical expression:
b - c < a < b + c
Where:
a, b, and c represent the side lengths of this triangle.
By applying the Triangle Inequality Theorem to the side lengths of this triangle, the number of non-identical triangles is given by:
5 + 7 > 10
12 > 10 (True).

The change in her September electric bill = -$0.44
The change in her October electric bill = -$6.84
The change in her November electric bill = -$1.19
The total change in her monthly electric bill over 5 months = Sum of all changes in her electric bill over 5 months

x = 23 degrees
Step-by-step explanation:
Angle on a straight line = 180 degrees

Angle in a triangle is 180 degrees
therefore 180 - 157 = 23 degrees

Answers
Solution
- We can plot the coordinates given using a graphing calculator as shown below:
- From the above, we can see that the sides are equal and the looks like a diamond
- Thus, the quadrilateral is a Rhombus
- Since all the angles are 90 degrees, it is also a square only that it was rotated.
- A square is a special type of rectangle, thus, the shape is also a rectangle
- A parallelogram as its opposite sides parallel and opposite angles equal. This is the same with our figure. Thus, it is also a parallelogram

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.
Answers
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.

Answers
Lauren will reach Andrea after 65 minutes of biking.
What do we mean by mathematical operations?A mathematical function called an operation, also known as an "operand" or "argument," transforms zero or more input values into a precisely defined output value.The quantity of operands affects the operation's arity.The operations that are most frequently studied are unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, and binary operations (i.e., operations of arity 2), such as addition and multiplication.So, because Lauren is traveling at a speed that is one kilometer per minute slower than Andrea's and vice versa, Andrea's speed is 3/4 km/min and Lauren's is 1/4 km/min.
Thus, Andrea will have biked 3/4 × 5 = 15/4 km in 5 minutes.Lauren will have to bike the following kilometers in total:
20 - 15/4 = 80/4 - 15/4 = 65/4 kmHer speed being 1/4 km/min, the amount of time passed will be:
(65/4)/(1/4) = 65Therefore, Lauren will reach Andrea after 65 minutes of biking.

If the probability of rolling one 3 and one 4 is 1/24, what is the probability of rolling two 1’s?
Answers
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.

Answers
If the function 5x+ y = 1 has the domain {-2, 1, 6}, then {11, -4, -29} is the corresponding range and the answer to your question is: letter D
Function 5x + y = 1
Domain {-2, 1, 6}
Process
Domain is the possible values of the independent variable.
Range is the values of the dependent variable.
Evaluate the function with each of the domain values to get "y"
When x = -2
5(-2) + y = 1
-10 + y = 1
y = 10 + 1
y = 11
When x = 1
5(1) + y = 1
5 + y = 1
y = -5 + 1
y = -4
When x = 6
5(6) + y = 1
30 + y =1
y = 1 - 30
y = -29
Range = { 11, -4 , -29}

An airplane left an airport flying at 180 mi/h. A jet that flies at 330 mi/h left one hour later. The jet follows the same route as the airplane at a different altitude. How many hours will it take the jet to catch up with the airplane? How many miles will the jet have flown?
Answers
Using the distance formula, Jet will take 2.2 hours to catch up with the airplane.
We will find the solution using distance formula.
distance formula is a formula that is used to find the distance between two points. These points can be in any dimension.
d=rt where
d is distance r is rate or speed and t is time
"distance airplane traveled" = "distance jet traveled"
Let x = hours "airplane" was flying
x-1 = hours "jet" was flying
.
180x = 330(x-1)
180x = 330x - 330
180x + 330 = 330x
330 = 150x
330/150 = x
2.2 hours = x
