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?
Answers
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)

Step-by-step explanation:
First, we can add 8+5.5+8 because of the two sides which are 8 and one that is 5.5. That is 21.5.
Then, we must find the diagonal edge. To do that, we can use the pythagorean theorem. It makes a triangle, so given that a^2+b^2=c^c, we can say that 3^2+5.5^2=c^c. Using a calculator, we can find the square root of 39.25, then add it to 21.5.

Hint: Percent error = | Prediction - Actual
x 100
| Actual
Round to the nearest percent.
[ ? ]%
Answers
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%

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

y is 5 when x is 6. (6, 5)
3(12) - 13

y is 23 when x is 12. (12, 23)
The formula for slope is y2-y1/x2-x1

Suppose that many large samples are taken from a population, and the
sample proportions center around 0.58. Which of the following is most likely
to be the population parameter?
O A. 0.68
OB. 0.58
O C. 0.78
O D. 0.48
Answers
Answer:
A- 0.68
Step-by-step explanation:
0.58 is most likely to be the population parameter, since the sample proportions center around this value.
Option B is the correct answer.
We have,
When many large samples are taken from a population, the sample proportions should converge to the population proportion.
If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.
In this case,
Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.
Therefore,
0.58 is the most likely population parameter.

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?
Answers
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.

What is the probability of getting an even number of dots in tossing a dice once if the ratio of even number to an odd number is 4:7?
Answers
Answer:
The probability is 4/11
Step-by-step explanation:
Here, we want to get the probability of getting an even number
Using the given ratio, the total of the numbers is 4 + 7 = 11
The number of even numbers is 4
So the probability of getting an even number will be the number of even numbers divided by the total of the numbers
We have this as 4/11
Identify the slope and y-intercept of the graph of the equation.
Answers
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

If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:
y = 3/2* x + b, provided b ⇒ y - intercept,
( 4 ) = 3/2 * ( 7 ) + b,
