1) Hank is looking to sell his motorcycle. He compiles these prices from the newspaper for bikes just like his
$2,000; $ 16,900; $15,100; $14,500; and $17,000. Is it more reasonable for Hank to use the mean or the
median to get a reasonable estimated price for his bike?
Answer:
The median
Step-by-step explanation:
If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.

Which of these functions has a y-intercept that is greater than that of the linear function represented by the table of values below, and why? ANSWER PLEASE
x- 2,4,6,7,9
y-9,13,17,19,23 (TABLE)
Answer choices:
A
y=x+9, because the y-intercept of the function represented by the table of values is 2
B
y=x+9, because the y-intercept of the function represented by the table of values is 5
C
y=8x+1, because the y-intercept of the function represented by the table of values is 2
D
y=8x+1, because the y-intercept of the function represented by the table of values is 5
Th y intercept of the table is:
(23-9)/(9-2)= 14/7=2
The answer is:
A
y=x+9, because the y-intercept of the function represented by the table of values is 2
What would be the new coordinates of a point that starts at (5,9) and is dilated by a scale factor of 2 and then translated 3 up and 2 right?
Answer:
(12. 21)
Step-by-step explanation:
Given the coordinate (5, 9), if it is dilated by a factor of 2, the resulting coordinate will be expressed as;
P = 2(5, 9)
P = (2(5), 2(9))
P = (10, 18)
If it is now translated 3 up and 2 right, then the final coordinate will be at;
P' = (10+2, 18+3)
P' = (12, 21)
Hence the final image will be at (12. 21)

Answer:
Its C
Step-by-step explanation:
Answer:
C. 3
Step-by-step explanation:
First I'll solve y + 1 = 3x - 12 for y.
y + 1 = 3x - 12 All you need to do for this first part is subtract 1 from both sides.
y = 3x - 12 - 1
y = 3x - 13
I'll use the point for x being 6, and x being 12.
3(6) - 13
18 - 13
5
y is 5 when x is 6. (6, 5)
3(12) - 13
36 - 12
y is 23 when x is 12. (12, 23)
The formula for slope is y2-y1/x2-x1
(23 - 5)/(12 - 6) Subtract 5 from 13, and then subtract 6 from 12.
18/6 Divide 18 by 6.

percent error?
Hint: Percent error = | Prediction - Actual
x 100
| Actual
Round to the nearest percent.
[ ? ]%
Answer:
Percent error is 44.4%
Step-by-step explanation:
Here, we want to get the percent error
From the question, prediction is 54 while actual value is 78
from the formula given;
Percent error = |prediction-actual|/actual * 100%
so we have
|54-78|/54 * 100%
= 24/54 * 100% = 44.4%

Find the total force on a piston of diameter 3.25 in., if the pressure (P) exerted on it is 150 lb/sq.In. Use 3.14 for and round to the nearest 50 lbs.
Answer:
1244 Ibf(Pounds force)
Step-by-step explanation:
The formula for Total force on a piston when given the diameter of the bore area =
F = P × π × d²/4
P = 150 lb/sq.In
π = 3.14
d = 3.25 in
Hence,
F = 150 lb/sq.In × 3.14 × 3.25 in /4
= 4974.9375 ÷ 4
= 1243.734375 Ibf(Pounds force)
Approximately = 1244 Ibf(Pounds force)
multiply by 4, then divide by 2 First term: 60

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 19)(0,19) and (3, 9728)(3,9728).
Answer:
y = 19*(8)^x
Step-by-step explanation:
We want to write an equation like:
y = a*b^x
That goes through the points (0, 19) and (3, 9728)
Then, when x = 0, we must have y = 19
Replacing those values in the equation we get:
19 = a*b^0 = a*1 = a
19 = a
Then the equation is:
y = 19*b^x
We also know that when x = 3, y = 9728
If we replace these values in the equation, we get:
9728 = 19*(b)^3
Let's solve this for b.
9728/19 = b^3
512 = b^3
∛512 = b = 8
Then the equation is:
y = 19*(8)^x

Here, we need to know about the concept of the alternate interior angle theorem. This says that the alternate interior angle of two parallel lines formed with one transversal is equal. For a more graphical explanation, please refer to the attachment below.
--------------------------------------------------------------------------
Given
∠GBD=4x+84
∠EFC=16x
m∠GBD=m∠EFC
Solve
4x+84=16x ⇔ Given
4x+84-4x=16x-4x ⇔ Subtract 4x on both sides
84=12x ⇔ Simplify
84/12=12x/12 ⇔ Divide 12 on both sides
x=7 ⇔ Simplify
Substitute the x value into each angle expression
∠GBD=4x+84=4(7)+84=28+84=112
∠EFC=16x=16(7)=112

Identify the slope and y-intercept of the graph of the equation.
Answer:
y = 1/3x - 2
Slope = 1/3
y- intercept = -2
Step-by-step explanation:
To find the slope and y-intercept, first put the equation in y = mx + b format, Where m is your slope and b is your y-intercept.
Step one: Subtract x from both sides
To translate x over to the right side of the equation, subtract x from both sides, leaving you with this equation:
x - x -3y = -x + 6; which simplifies to:
-3y = -x + 6
Step Two: Divide Every Term By Negative 3
To get y alone by itself we need to cancel out -3 on the right side of the equation, to do that you must divide every term by negative 3 leaving you with this equation:
[tex]\frac{-3}{-3}[/tex]y = [tex]\frac{-1}{-3}[/tex]x + [tex]\frac{6}{-3}[/tex]; which simplifies to:
y = 1/3x - 2
M, slope, = 1/3
B, y-intercept, = -2
