Typically, the graph will have a labeled line such as f(x) = ... To find f(3), identify 3 on the x-axis, then trace vertically to the graph line and read the corresponding y-value.

Example answer: To determine f(3), we take the input value 3 and seek its output. Locate x = 3 along the x-axis, then move up or down to the graph line at that point. The y-coordinate at this intersection gives the value of f(3).

What are the domain and range of the function on the graph? The domain includes all integers, and the range is y ≥ 0. The domain
Inessa [3907]

Answer:

The function's domain means that x can take any real number value and the function's range is y > 0.

Step-by-step explanation:

In a Cartesian coordinate system, a graph of an exponential function approaches y = 0 in the second quadrant and rises in the first quadrant.

Thus, as x approaches -∞, y approaches 0 without ever reaching it, and as x tends towards +∞, y also approaches +∞.

Consequently, the domain of the function indicates that x can be any real number and the range signifies that y > 0.

A researcher evaluates the significance of a multiple-regression equation and obtains an F-ratio with df = 2,24. How many partic
Inessa [3907]

Answer:

N=27 individuals

Step-by-step explanation:

Analysis of variance (ANOVA) is employed to assess the differences among group means in a sample.

The sum of squares refers to the cumulative square of variation, which is the dispersion between each individual value and the overall mean.

While conducting a multiple regression, we aim to understand the relationship between multiple independent or predictor variables and one dependent or outcome variable.

<passuming we="" have="" src="https://tex.z-dn.net/?f=k" id="TexFormula1" title="k" alt="k" align="absmiddle" class="latex-formula"> independent variables and j=1,\dots,j individuals, we are able to define the corresponding formulas of variation:

SS_{total}=\sum_{j=1}^n (y_j-\bar y)^2

SS_{regression}=SS_{model}=\sum_{j=1}^n (\hat y_{j}-\bar y)^2

SS_{error}=\sum_{j=1}^n (y_{j}-\hat y_j)^2

We also have this property

SST=SS_{regression}+SS_{error}

The model's degrees of freedom in this instance is determined by df_{model}=df_{regression}=k=2 where k = 2 represents the number of variables.

For the error's degrees of freedom in this case, it is indicated by df_{error}=N-k-1=24. Knowing k allows us to ascertain N.

N=24+k+1=24+2+1=27

The total degrees of freedom would be df=N-1=27 -1 =26

This leads us to conclude that the correct answer is N=27 participants.

-3x + 2c = -3, solve for x
zzz [4022]

Answer:

x=2c/3+1

Step-by-step explanation:

First, subtract 2c from both sides.

−3x=−3−2c

The equation has been transformed into standard form.

−3x=−2c−3

Next, divide both sides by −3.

-3x/-3=-2c-3/-3

Dividing by −3 negates the multiplication by −3.

x=-2c-3/-3

Finally, divide −3−2c by −3.

x=2c/3+1

Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?
zzz [4022]

Answer:

1/5

Step-by-step explanation:

Amir and Tamara each consumed 2/5 of the candy bar.

The total consumed is 2/5 + 2/5 = 4/5.

Since 4/5 of the candy bar has been eaten, 1/5 remains.

This is because 5/5 minus 4/5 equals 1/5.

(Note that 5/5 represents a whole candy bar).
