Answer:
Step-by-step explanation:
There isn't really a correct answer, because reading the data associated the line will have a margin of error. What I read it as and what you read it as would be slightly different. With that said I will try my best.
I need at least two points on the line that seem accurate.
I like one point at Latitude 40 and temperature 51 call it 50 (40, 50)
Another point I like is Latitude 15 and temperature 81 or 80 (15, 80)
to find the line we use the slope and one point on the line
with two points you can calcuate the slope m = Δy / Δx
m = (50 - 80) / (40 - 15)
= -30 / 25
= - 1.2
now find the y intercept y when x = 0 (the x -axis)
y - y1 = m ( x - x1 ) point 1 (40, 50) slope of -1.2
y - 50 = -1.2 ( 0 - 40)
y = -1.2(-40) + 50 i combined a few steps here to solve for y
y = 98
so from your data and line I get an answer of
y = -1.2x + 98
to double check my answer I used a graphing calculator to do all of the work!
the graphing calculator (attached image) using linear regression got an answer of
y = -0.983667x + 103.9

Answers
Answer:
Bryce is wrong in step 1 because he did not distribute 3 over 5/3
Explanation
Given the steps taken by bryce as shown, we are to find where he made an error
[tex]\qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}[/tex]
Given the expression;
[tex]\dfrac83&=3\left(c+\dfrac53\right)\\\\ \\[/tex]
Step 1:Expand the bracket using the distributive law;
8/3 = 3c + 3(5/3)
Simplify
8/3 = 3c + 15/3
Step 2: Subtract 15/3 from both sides
8/3 - 15/3 = 3c+15/3-15/3
(8-15)/3 = 3c
-7/3 = 3c
Step 3: Multiply both sides by 1/3
-7/3 * 1/3 = 3c * 1/3
-7/9 = c
Swap
c = -7/9
From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect

Okay so basically in a triangle, the sum of any two sides should be greater than the third remaining side. So if we had a triangle with sides A, B, and C, A+B>c, A+C>B, and B+C>A. If you look at 1,2, and 4, 1=2=3 which is less than 4. That is why that is not a triangle.

What is the equation of the line that passes through the point (−1,−5) and has a slope of −3?
Answers
Answer:
[tex]y=-3x-8[/tex]
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Plug the slope (m) into the equation
We're given that the slope is -3. Plug -3 into the equation
[tex]y=-3x+b[/tex]
2) Solve for the y-intercept (b)
To solve for b, plug the given point (-1,-5) into the equation as (x,y).
[tex]-5=-3(-1)+b\\-5=3+b[/tex]
Subtract 3 from both sides
[tex]-5-3=3+b-3\\-8=b[/tex]
Therefore, the y-intercept is -8. Plug -8 back into our original equation as b
[tex]y=-3x-8[/tex]

Kimberly collects data on the average temperatures in January in her state over the last 30 years. She then calculates the mean and median for the data set.
Kimberly decides to collect data from two more years and add them to her original data set. The first year, the average temperature is colder than it had been for any of her previous recorded data. The second year, the average temperature is warmer than for any of her previous data.
Which statement describes how adding the two new temperatures to Kimberly's data set could change the statistical measures?
A
The mean and median may both change.
B
The mean and median will both stay the same.
C
The median may change, but the mean will not change.
D
The mean may change, but the median will not change.
Answers
Answer:
D.) The mean may change, but the median will not change.
Step-by-step explanation:
By adding two new values to the existing dataset ; this two values are extreme values as described in the dataset.;
As the warmer will be the new minimum and the colder the new maximum .
The median value being the midpoint of the dataset when arranged in order will definitely not be affected by these new additions are at the beginning and end of the data set. Hence, the previous median points will Also be the new median points.
As for the mean, it has to do with calculation the average value, despite the number being at the extreme, the new points may take up any value and hence will affect the new sum and ultimately the obtained average.
Therefore,The mean may change, but the median will not change.

Step-by-step explanation:
The key take-away regarding what relation is or is not a function is the following: a function has no repeated x-values.
The x-values in the table are -3, -1, 0, 2, so any suggested ordered pair with one of those as an x-value cannot be added to the table. The only such pair in the list is the first one (-3, 4). It cannot be added. All of the remaining three pairs can be added and the relation will remain a function.
Identify the expression that has the largest value when a<-1
1-2a
a
a^2
a^3
Answers
Answer:
1-2a is the largest for -1 > a > -2.41
a^2 is the largest for -2.41 > a.
Step-by-step explanation:
We want to find the expression with the largest value.
Remember that the sign is important here, because:
1 is larger than -10
So we will look at the expressions that, when evaluated in a negative number, give a positive number.
The only two options in the case:
a < -1
are:
1-2a
and
a^2
So we have a linear equation and a quadratic equation.
We know that quadratic equations grow a lot faster than linear equations for all values larger than 1 (or minus one, because the sign does not matter).
if -1 < a < 1, a quadratic function grows really slow, but this is not the case.
So from now, we can guess that a^2 is larger.
But let's solve it graphically.
Let's define two functions:
f(a) = 1 - 2*a
g(a) = a^2
Now we can graph these two, and look at the region a < -1, and see which one is larger.
in the image, you can see that there is a small region from:
-1 > a > -2.41
Where the linear equation is larger, and for:
a < -2.41
The quadratic equation is larger.

Answers
Answer:
m∠ECD = 145°
m∠FCA = 35°
m∠PDF = 70°
Step-by-step explanation:
For ∠ECD:
- You can find this angle using supplementary angles. ∠ECD and ∠ECB are supplementary, meaning they add to 180°. Since the measure of ∠ECB is provided, you can subtract that from 180° to get m∠ECD:
180 - 35 = 145°, so m∠ECD = 145°
For ∠FCA:
- You can solve this problem using the Vertical Angles theorem. It states that vertical angles are congruent. ∠FCA's vertical angle pair is ∠ECB, which is 35°, so you can deduce that m∠FCA = 35°
For ∠PDF:
- You can find the measure of this angle by using supplementary angles like for ∠ECD. ∠PDC is supplementary to ∠PDF, and it's value is given. so you can find PDF by subtracting the value of ∠PDC from 180:
180 - 110 = 70°; m∠PDF = 70°

A flat rate shipping box is in the shape of a rectangular prism. You estimate that the volume of the box is 350 cubic inches. You measure the box and find that it has
a length of 10 inches, a width of 9 inches, and a helght of 4.5 inches. Find the percent error. Round your answer to the nearest tenth of a percent.
The percent error is about %.
Answers
Answer:
13.6%
Step-by-step explanation:
Step 1
Find the actual volume of the box
Volume = Length × Width × Height
You measure the box and find that it has a length of 10 inches, a width of 9 inches, and a helght of 4.5 inches.
Volume = 10 inches × 9 inches × 4.5 inches
Volume of the box = 405 cubic inches
Step 2
Calculate the percent error
|Estimated value - Actual value|/Actual value ×100
Estimated value= 350 cubic inches
Actual value = 405 cubic inches
= |350 - 405|/405 × 100
= |-55|/405 × 100
= 55/405 × 100
= 13.580246914%
Approximately = 13.6%
The Percent error is 13.6%
