The slope is 2 exactly.
Two variables are defined, a regression equation is given, and one data point is given.
Hgt
Age
height in inches
age in years of a child
=
Hgt 24 + 2.72(Age)
The data point is a child 12 years old who is 60 inches tall.
Need help on part a
Given the following data:
Age in years of a child = 12 years.Height in inches = 60 inches.What is a residual value?A residual value can be defined as a difference between the measured (given or observed) value from a scatter plot and the predicted value from a scatter plot.
Mathematically, the residual value of a data set can be calculated by using this formula:
Residual value = given value - predicted value
Next, we would determine the predicted value by using the given regression equation as follows:
Hgt = 24 + 2.72(Age)
Hgt = 24 + 2.72(12)
Hgt = 24 + 32.64
Predicted value, Hgt = 56.64 inches.
Now, we can determine the residual value as follows:
Residual value = given value - predicted value
Residual value = 60 - 56.64
Residual value = 3.36 inches.

one side of an isosceles triangle is three times as long as another side of the triangle. If the perimeterof the triangle is 140, then what is the length of the base of the triangle?
Answer:
20
Step-by-step explanation:
P, perimeter of triangle = a + b + c
We're given P = 140 and it is an isosceles triangle.
We can change P to be 2a + b since 2 sides are equal in an isosceles
So, 140 = 2a + b
One side is 3x longer than the other. The equal sides in the triangle can not be 3x longer than each other since it is equal.
And the isosceles sides are longer than the 1 base side.
So if a = our isosceles sides, and b is our base side, than a is 3x our base side which can be written as a = 3b
Now, 140 = 2(3b) + b, and we can now solve
140 = 6b + b => 140 = 7b
20 = b
Our base length is 20.
For what values of c and d would the rectangles be similar?
By using the definition of similarity and the dimensions of each rectangle, a rectangle with d = 72 and c = 45 fulfills the height to width ratio of 8 / 5. (Correct choice: C)
How to find the dimensions of a rectangle similar to other rectangle
Two rectangles are similar if both hold the same height to width ratio. Mathematically speaking, the two rectangles must fulfill the following requirement:
b / a = d / c (1)
Where:
a - Width of the big rectangle.b - Height of the big rectangle.c - Width of the small rectangle.d - Height of the small rectangle.If a = 50 and b = 80, then the ratio of the second rectangle must be:
d / c = 8 / 5
By direct comparison with any of the four choices, we find that a rectangle with d = 72 and c = 45 fulfills the height to width ratio of 8 / 5.

a physician orders 16 oz of 25% solution to be made from 10% and 50% stock solutions. how many ml of 50% solution are needed?
180ML of 50% solution are needed.
What is a solution?Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution. An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself. Particularly but not exclusively for polynomial equations, the solution of an equation is frequently referred to as the equation's root.
EXPLANATION : To solve this question, we have initial stock solution of 10% and 50% concentration. We need to make final solution of 25% concentration of volume 16oz. [tex](1oz \approx 30ml)[/tex]
To find :- Volume of 50% required
Let us assume we require x oz volume of 50% stock Solution , Then volume of 10% stock added will be (16-x) oz.
Formula used here:- C1V1 + C2V2 = C3V3
Where C1 = 50% = 0.5 , V1 = x oz & C2 = 10%= 0.1 , V2= 16-x oz
C3 = 25% = 0.25 , V3= 16oz
Putting values we have
(0.5*x) + (0.1(16-x)) = 16*0.25
0.5x + 1.6 - 0.1x = 4
x = 6
Hence Volume of 50% solution = x = 6 oz = 6*30 ml = 180ml

If triangle GHJ is isosceles find the value of x
Answer:
x = 5
Step-by-step explanation:
Because an isosceles triangle's angles will always add up to 180, it's quite simple plugging in angle J into a formula to find our answer.
Before we begin, recall that the bottom two angles of an isosceles triangle are equal to the other. Thus:
Unknown angle (H) = 14x+1
So...
38 + 14x + 1 + 14 x + 1 = 180
40 + 28x = 180
-40 -40
28x = 180
28x/28 = 180/28
We get:
x = 5
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Note that:
Base Angles Of An Isosceles Triangle Are Equal.Calculating For the Value Of X
Since Base Angles are Equal(14x + 1)° + (14x +1)° +38° = 180°
Removing Brackets14x + 1 + 14x + 1 + 38 = 180°
28x + 2 + 38 = 180°

The null hypothesis is [tex]H_0:\mu=3[/tex] and the alternative hypothesis is [tex]H_1:\mu > 3[/tex]
There are two hypothesis considered in a statistical test. They are:
Null hypothesis ([tex]H_0[/tex])Alternative hypothesis ([tex]H_1[/tex])Formulation of null and alternative hypothesis are considered as the first step of a statistical procedure. The whole procedure, then, continues on testing whether to accept or reject these hypotheses.
Null Hypothesis is the actual hypothesis which is tested. Alternative hypothesis, as its name suggests, is the hypothesis accepted when the null hypothesis is rejected in the test carried out.
Here the sociologist is carrying out the test on the mean number of cars, [tex]\mu[/tex].

the null hypothesis will be ,[tex]\bold{H_0:\mu=3}[/tex]

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line on the diagram given is rise/run = 3/4.
How to Calculate the Slope of a Line?The formula for calculating the value of the slope of a line on a coordinate plane is expressed as: change in y / change in x = rise of the line / run of the line.
Slope = rise/run.
Given the line shown in the graph above, we have the following:
The blue line represents the rise of the line = 3 units
The red line represents the run of the line = 4 units
Slope (m) of the line = rise/run = change in y / change in x = 3 units/4 units
Slope (m) = 3/4
Therefore, the slope of the line on the diagram given is rise/run = 3/4.
