A line goes through points (-2, 18) and (4, 3). What is the slope of the line?
A. 12
B. -1.25
C. -2.5
D. -5
Answers
Answer:
-2.5
Step-by-step explanation:
The slope can be found by
m = (y2-y1)/(x2-x1)
= (3-18)/(4- -2)
= -15/(4+2)
=-15/6
= -5/2
-2.5
Answer:
C. -2.5
Step-by-step explanation:
Slope is: \(m=\frac{y_2-y_1}{x_2-x_1}\)
We are given the points (-2,18) and (4,3).
\(m=\frac{3-18}{4-(-2)}= \frac{-15}{6} =-\frac{15}{6}= -\frac{5}{2}\)
The options are given in decimals.
\(-5/2=-2.5\)
Option C is the correct answer.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Find the median of the data in the dot plot below.
Answers
Answer:
40
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact value in the middle then it is the average of the values either side of the middle.
The data is arranged in ascending order within the dot plot
There are 10 values in the data set
Thus the median is between the fifth and sixth values.
Counting from the left (35)
The fifth value = 39 and the sixth value = 41, thus
median = \(\frac{39+41}{2}\) = \(\frac{80}{2}\) = 40
Answer:
Step-by-step explanation:
Data:
35 , 38, 38 , 39 , 39, 41, 42 , 43, 43, 44
Total number of data = 10
Number of data is even. so, median is the average of (n/2)th term & (\(\frac{n}{2}+1\) ) middle term,
Median = average of 5th and 6th term
= (39 + 41)/2 = 80/2 = 40

Space used (includes formatting): 0 / 15000
Answers
Answer: all awnsers below
Step-by-step explanation:
1. Define the number of coin flips to be simulated (e.g., 1,000 flips).
2. Initialize two counters, `headsCount` and `tailsCount`, to keep track of the number of heads and tails, respectively.
3. Repeat the following steps for the specified number of coin flips:
a. Generate a random number between 0 and 1.
b. If the generated number is less than 0.5, increment `headsCount` by 1. Otherwise, increment `tailsCount` by 1.
4. Calculate the experimental probabilities by dividing `headsCount` and `tailsCount` by the total number of coin flips.
5. Compare the experimental probabilities with the theoretical probability (0.5 for a fair coin).
6. Repeat the simulation multiple times (e.g., 100 times) and calculate the average difference between the experimental and theoretical probabilities to evaluate the simulation's accuracy.
By running this simulation multiple times, we can assess how closely the experimental probabilities match the theoretical probability on average. This simulation provides a different approach compared to the previous one and can be used to model the situation with more flexibility and accuracy.

Step-by-step explanation:
Given equation,
→ 3x + 5 = 2x - 15
Now the value of x will be,
→ 3x + 5 = 2x - 15
→ 3x + 5 - 2x = -15
→ 3x - 2x = -15 - 5
→ x = -(15 + 5)
→ [ x = -20 ]
Hence, the value of x is -20.

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Standard form:
5x+y=7

Slope-intercept form:
y= -3x-2 or y= -3x+(-2)
Standard form:
3x+y=-11
Step-by-step explanation:
1. Points: (-2, -3) and (0, 7).
Find slope: m=7-(-3)/0-(-2)=7+3/0+2=10/2=5
Point-slope form:
y-7=5(x-0)
Slope-intercept form:
y=5x+7
Standard form:
-5x+y=7
2. Points: (-6, 7) and (0, -2)
m= -2-7/0-(-6)= -9/6= -3
Point-slope form:
