a) according to the map on the left, Central Park is about 50 blocks long by 9 blocks wide. what is the approximate area of the park? show your work.
b)lets say the area of the map is 21 square inches. you want to make q enlarged map of central park to take with you on your journey. describe how you can determine the area of the the enlarged map.
c)supposed the scale factor you will ise to enlarge the map is 5:1. what is the approximate area of the park of the park in your enlarged drawing.
d) how did you apply proportional reasoning as you worked through these problems?
Answer:
pls give brainlist
Step-by-step explanation:
a. [tex]\frac{50 blocks (L)}{9 blocks(W)\\}[/tex] 50 x 9 = 450. A=450
b. I can scale the unit rate of the area given above and largen the area of the map. Ex. [tex]\frac{7}{3}[/tex]=[tex]\frac{21}{6}[/tex] <---(scaled by 2)
Then we can enlarge it however we want so,
[tex]\frac{21}{6}[/tex] = [tex]\frac{42}{12}[/tex] <--(scaled by 2 once more)
If the statement above is true then we can scale times 4.
[tex]\frac{7}{3}[/tex]= [tex]\frac{42}{12}\\[/tex] <---(scaled by 4)
A= [tex]\frac{42}{12\\}[/tex]

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.

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:

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.
slopeeeee is soo hardddd brehh
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.
3
The slope to the line y + 1 = 3(x - 4) is 3, which is C.

Question 4 of 10
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
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.

Hunter assumed he would only get 54
problems correct on his test, but he
actually got 78 correct. What was his
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%

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)

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?
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.
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
HELPPP MEE PEOPLE PLSSS NO BOTS OR I WILL REPORT BUT PLEASEEE HELPPP MEEE Find the point-slope equation of the line using the point (7,4) and slope of 3/2
Use the slash key ( / ) to indicate a fraction.
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
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,
4 = 21/2 + b,
b = 4 - 10.5,
b = -6.5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
