A function y = 10 a not linear function
We know that the general form of linear function is f(x) = a + bx
A linear function has one independent variable (for above function x) and one dependent variable(here, f(x)).
The graph of linear function is always a straight line.
Let y = f(x)
So, y = a + bx
where b is the slope of line
and a is the y-intercept
here, the independent variable is x and the dependent variable is y.
We have been given a function y = 10
The graph of y = 10 is a horizontal line parallel to x -axis and intersects y-axis at (0, 10)
There is no y-intercept and the slope is undefined.
Therefore, given function is not a linear function

A certain region of America with over 500,000 households has a mean household income of $70,000 with a standard deviation of $20,000. Economists plan to take random samples of 625 households and calculate the sample mean income for each sample. Calculate the mean of the sampling distribution of x-bar.
Answer: Mean: 70,000
Standard Deviation: 500
Step-by-step explanation:
The mean is 70, 000 and standard deviation is 800.
What is Standard Deviation?The term "standard deviation" (or " σ ") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
A certain region of America with over 500,000 households.
Mean, [tex]\mu[/tex] = 70,000
and, Standard Deviation, [tex]\sigma[/tex] = 20,000
n = 625
So, the new mean = old mean
= 70, 000
and, the standard deviation = [tex]\sigma /[/tex]√n
= 20,000 / √625
= 20,000 / 25
= 800.
Hence, the mean is 70, 000 and standard deviation is 800.

Step-by-step explanation:
Answer:
Point A = (0,1) Point B = (1,2) Point C = (2,4)
Step-by-step explanation:
To find a point's "ordered pair" (x and y coordinates), consider each line a single digit unless the problem states/shows otherwise (ex. if the lines were evidently counting by 2's). Here, we can see each line represents a single digit. First count how many lines to the left/right of the y axis the point is (this will be your x point - ex. point B in this problem has an x valued at 1 because the point was one line to the right of the bold vertical line in the middle (the y axis). If the point is to the left, it is a negative x value, right would be positive, and if the point is on the y axis line. x is 0. You are essentially counting how far along the x axis the point is. Same applies to the y values, given you do the opposite and count how far from the x axis (horizontal bold line) the point is. Above that line is positive, below is negative, and again, if the point is on the x axis (bold horizontal line), the y value is 0. Then simply fill your values in in their corresponding places in the brackets: (x,y).
Hope this helps :) I know math can be especially hard to grasp so it's always okay to ask for help/explanation.

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain
{_____________________________
whoever does best get brainliest
Answer:
The correct formula should be I= 600(0.07)(2). Juanita made a very common error, she didn't put the percentage of interest in decimal form; or she didn't put the percent sign on it so we know to put it in decimal form. Her error will make a big difference; with using her calculations the answer would be $8,400. With the correct formula the answer is $84.
Hope this help! :)
Given :-
Juanita borrowed $600 .Rate of Interest = 7% .Time = 2yrs .To find :-
Error made by her.Answer :-
As we know that the formula for Simple interest is ,
SI = P*R*T / 100Substitute ,
I $600* 7 * 2 / 100 I = $ 84 .So here she did not write 7 % as 7/100 instead she wrote 7 .

Susanna's family traveled 5 7 of the distance to her grandmother's house on Saturday. They traveled 1 2 of the remaining distance on Sunday. What fraction of the total distance to her grandmother's house was traveled on Sunday?
Answer:
1/7
Step-by-step explanation:
Please write these fractions as 5/7 and 1/2. 5 7 and 1 2 are incomplete and confusing.
On Saturday the distance traveled was 5/7 of the total distance.
2/7 of that total was left for Sunday. Half of 2/7 is 1/7.
1/7 of the total distance was traveled on Sunday.

8-3(6-6x) please help
Answer:
-10 + 18x
Step-by-step explanation:
8-3 (6-6x)
distribute -3 with the numbers inside the parenthesis and you end up with
8 -18 + 18x
and you simplify by subtracting 18 from 8 so you get
-10 + 18x
The simplified form of the expression 8 - 3(6 - 6x) is -10+18x.
To simplify the expression 8 - 3(6 - 6x), we can apply the distributive property to remove the parentheses.
Distribute the -3 to both terms inside the parentheses:
8 - 3 × 6 + 3 × 6x
Simplify the multiplication:
8 - 18 + 18x
Combine like terms:
-10 + 18x
Therefore, the simplified expression is -10 + 18x.

Identify the vertex and axis of symmetry of the graph of g(x) = |x|- 8
The vertex of the absolute function g(x) = |x|- 8 lies at (0,-8).
What is an absolute function?The absolute value or modulus of a real number x, denoted by |x|, is its non-negative value regardless of its sign.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the absolute function is g(x) = |x| - 8. The vertex will be calculated by plotting the function on the graph.
From the graph, the vertex of the absolute function lies at the point ( 0,-8). The graph is attached with the answer below.

Platter has six veggie wraps 12 turkey wraps and cost 64.50 another platter has eight veggie wraps turkey wraps and cost 56 what is the cost of a veggie wrap
Answer:
$3.25
Step-by-step explanation:
The computation of the cost of a veggie wrap is shown below:
Let us assume the veggie strap be x
And the turkey wrap be y
Now the equations are
6x + 12y = $64.50
x + 2y = $10.75
8x + 8y = $56
x + y = 7
Now
x + 2y = $10.75
x + y = $7
y = $3.75
So x = $7 - 3.75
= $3.25
Paula salió de su casa rumbo al trabajo avanzo 8km al este y 13km al norte. Si hubiera un camino recto desde su casa a su trabajo ¿Que distancia recorrería por ese camino?

Con la informacion de la pregunta e hecho un diagrama de la situacion. Podemos ver en el diagrama que el recorido forma un triángulo rectángulo. Entonces para saber la distancia que recorreria por el camino recto desde su casa a su trabajo tendriamos que calcular el valor de x, que se puede calcular usando el teorema de pitagoras que es el siguiente.
[tex]a^{2} + b^{2} = c^{2}[/tex]
donde a y b son el ancho y el alto del triangulo y el c seria x

Taylor and Katy repeatedly toss a fair coin. Katy wins if heads are thrown, Taylor wins if tails are thrown, and the game ends when someone has won three times. Katy is currently behind 1 to 2. The chance Katy wins is:
Answer:
25%
Step-by-step explanation:
In order to find the chance/probability that Katy wins we need to first find the probability of her winning a single coin toss and then multiply it twice. This is because Katy has 1 win already and needs two more win the entire game. Since a coin toss only has 2 options and only 1 of those outcomes will cause Katy to win, then this means that the probability of Katy winning is 1/2 or 50%. Now we can multiply this probability twice to get the probability of Katy winning the entire game
1/2 * 1/2 = 1/4 or 25%
