Answer:
f(x) = 4x + 10
Step-by-step explanation:
The given information is in the form f(x) = y.
f(0) = 10 means if x is 0, y is 10. This is the point (0,10)
Likewise, f(6) = 34
means when x is 6, y is 34. That is the point (6,34).
Slope is y-y / x-x
34-10 / 6-0
is 24/6.
The slope is 4.
The y-intercept is where x is 0, that is 10.
y=mx+b is slope-intercept form. Fill in the slope, 4 for m and the y-intercept, 10, for b.
y = 4x + 10
but they also asked to call it f, so for function notation, use f(x) instead of y.
f(x) = 4x + 10

A classroom has twenty-five students that are all 14-years old. If you list their ages and their heights as ordered pairs (age, height), which statement is true?
It is not a relation, but it is a function.
It is a relation but not a function.
It is neither a relation nor a function.
It is both a relation and a function.
When one lists their ages and their heights as ordered pairs (age, height), the statement that is true is D. It is both a relation and a function.
In mathematics, what is a relation?A relation between two sets is a collection of ordered pairs that each contain one object from the other set. If the ordered pair (x,y) is in the relation and the object x is from the first set and the object y is from the second set, the objects are said to be related. A relation is a type of function.
A function is a relation that states that there should be only one output for each input (or) we can say that a function is a special type of relation (a set of ordered pairs) that follows a rule, i.e., every X-value should be associated with only one y-value.
It should be noted that based on the information, only one value can be attributed to each person. Therefore, the correct option is D.

in a two-factor anova, if there is a significant interaction effect, what should be your interpretation for the main effects of factor a and factor b?
In two - factor ANOVA , if there is significant interaction effect then Not necessary that main effects of both factors a and b is significant.
A two- way ANOVA (analysis of variance) is a statistical test used to analyze the difference in means of three or more groups.
Two-Way ANOVA is used to estimate how the mean of a quantitative variable varies according to the levels of two categorical variables. Use two-way ANOVA when you want to know how the combination of two independent variables affects the dependent variable.
Interaction effects occur when the effect of one variable depends on the value of another variable. Interaction effects are common in ANOVA and designed experiments.
We see that interaction effect in ANOVA test is significant . but interaction effect significant is not implies the significance of main effects of factors a and b. So, we conclude that main effects of factor a and b need not be significant.

Find the slope between the points
below. Simplify your answer.
(-10, 5) and (14,-3)
Slope between the points (-10, 5) and (14,-3) is -1/3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find slope between points (-10, 5) and (14,-3)
m=-3-5/14+10
m=-8/24
m=-1/3

Write an equation for each line using slope intercept form
Answer:
y = -5/3 - 3
Step-by-step explanation:
Since it's given a graph, we can use rise over run to figure it out
We pick 2 points that are integers on the graph , which means two points on the graph that the line goes through
Example- I picked (-3, 2) and (0, -3), you can indicate them so you don't forget or anything
We now draw a triangle formed by those two points (a line that goes from (-3, 2) to (-3, -3) and a line from (0, -3) to (-3, -3)
Rise (Which is the height of the triangle you just drew) is 5 units, but it's going down, so -5
The base (Run) is 3 units. Using rise/run, the slope is -5/3
The y-intercept, which is at the point where the graph crosses the y-axis, is -3.
The slope intercept form is y=mx+b, where m = slope and b = y-intercept, so the equation of the graph is y = -5/3x -3
the patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 2.3 days. what is the probability of spending more than 2 days in recovery? (round your answer to four decimal places.)
When the patient recovery time from a specific surgical procedure is normally distributed, with a mean of 5.2 days and a standard deviation of 2.3 days, the probability of spending more than 2 days in recovery will be 0.61.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. Information about the likelihood that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is used in epidemiology to comprehend the connection between exposures and the risk of health effects.
Here,
z=(X-μ)/σ
X=2
μ=5.2
σ=2.3
Z=(2-5.2)/2.3
Z=-1.39

growth or decay, and determine the percentage rate of increase or decrease.
y = 90(1.02)
The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.
y = 90(1.02)^x
The general form equation is:
y(x)= a(1+r)^x such that r is the decay percent.
on comparing,

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half .acc to our question-

D. 4 cm³/g
E. 0.25 g/cm³
The density is the ratio of mass to volume of an object thus the density of the given test sample is 4 g/cm³ thus option (C) will be correct.
What is density?Density or mass density is the mass of any object per volume.
For example, if the metal has a 100 kg mass and an area of 10-meter square then 100/10 = 10 kg/meter square will be the density of the given object.
Density can be uniform or non-uniform.
Density is the division of mass and volume and the mass must be for the quantity of the volume only.
Given that,
Mass = 10 g

x^2 - 6x = 0
Notice that one of the solutions is trivial, and it is x = 0.
If now we assume that x ≠ 0 and divide both sides by x, we get:

What is average weight?The weighted average is calculated by adding up all the variables, multiplying by their weight, and dividing by the sum of the weights. Instead of treating each item equally, a weighted average or mean multiplies each item being averaged by a number based on its relative importance.

Answer:
The slope of y = 5x - 4 is 5.
Notice that the equation, y = 5x - 4, of the line is written in the form y = mx + b. Thus, it is in slope-intercept form. When the equation of a line is in slope-intercept form, we know that the slope of the line is equal to m, the coefficient of x.
In y = 5x - 4, the coefficient of x is 5. Thus, the slope of the line, y = 5x - 4, is 5.
