A researcher studying koi fish collected data on three variables, A, B, and C. The following residual plots show the residual for a model for predicting each variable from the age of the fish
Answers
Answer:
Plot for Variable C Only
Step-by-step explanation:
Trust me, unless your teacher switched the order of the charts in which case it's the linear one!
The residual plot is a form of scatter plot that shows the difference between the observed value and the actual value.
The plot that supports a linear model is plot A.
The complete question requests that we select all plots that can be used as a linear model.
For a residual plot to be used as a linear model, the pattern of the residual plot must be at random (i.e. it must not show any obvious pattern)
From the given plots (see attachment), we have the following observation.
Plot A shows no patternPlot B shows a curve (like a quadratic function)Plot C shows a linear patternHence, only plot A can be used as a linear model.

find an equation for the line below
Answers
Answer:
Look at the dotted points on the line in your graph. check their coordinates, for your ease i am attaching a picture, please have a look.
so the two coordinates we have is : ( 3 , 1 ) , (- 1 , - 5)
Now let's find the gradient from these two coordinates.
[tex]\frac{y_{1}-y_{2} }{x_{1} -x_{2} }\\\\=\frac{1-(-5)}{3-(-1)}\\\\=\frac{6}{4}\\= 1.5[/tex]
Now we use the equation of a straight line and here , you can use any of the coordinates. For my ease, I am using the first one:
[tex]y-y_{1} = m (x-x_{1})\\ y- 1 = \frac{3}{2} (x-3)\\\\2y-2 = 3x - 9\\2y - 3x = -7[/tex]
In two or more complete sentences, describe how to find the interval(s) where the function is decreasing and how interval notation is used to express the interval(s). In your final answer, include the interval in which the function is decreasing.
Answers
Answer:
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)

Answers
Answer:
15 feet
Step-by-step explanation:
A typical diagram has been shown.
Joel's hand touches the bottom of the pool, point A as shown, 12 feet below the surface of the water.
Todd's foot is at the diving platform, at point B as shown, 3 feet above the surface of the water.
Let S be the point on the surface of the water.
So, the vertical distance between Joel's hand and todd's feet
=AS+SB
=12+3
=15 feet.

This is about division of fractions.
Option C; 7 and one half
When Dividing fractions, we change the sign to multiplication sign and the make the get the reciprocal of the divisor i.e. the divisor's numerator to be the denominator and the denominator to be the numerator. Thereafter we multiply by the dividend.Thus;
3 ÷ 2/5 = 3 × 5/2
>> 15/2
>> 7½
Thus, looking at the options, the only one that corresponds with our answer of 7½ is option C.
So, option C is the correct answer.

Slope problem im pretty sure it is -1/3 correct me if im wrong
Answers
The answer is -3.
Explanation:
The slope of a line is the ratio of how many units the line moves up or down the y axis to how many units the line moves across the x axis. In other words, it’s the rise/run of a line.
In the graph in the attached picture, every time the x axis increases by one, the y axis decreases by 3. Therefore, the ratio would be -3/1.
-3/1 is equal to -3, making the slope of this line -3.

The sum of the first n odd numbers is n^2
This can be proven, but for 5 odd numbers, 1,3,5,7,9, the sum should be 5^2, or 25, which it is
So for the first 44 odd numbers, the sum is n^2=44^2=1936

10 POINTS PLEASE HELP ASAP!!! What is the length of the altitude of the equilateral triangle below?
Answers
Step-by-step explanation:
Hey there!
Looking on figure we find that triangle ABC is a Right angled triangle.
Taking reference angle as C, we get;
Perpendicular (p) = a
Base(b) = 5
And hypotenuse (h)= 10
Now;
Using Pythagoras relation, we get;
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]a = \sqrt{ {10}^{2} - {5}^{2} } [/tex]
[tex]a = \sqrt{100 - 25} [/tex]
[tex]a = \sqrt{75} [/tex]
[tex]a = 5 \sqrt{3} [/tex]
Therefore, answer is Option E.
