Answer:
<u>25%</u> is the percent error.
Step-by-step explanation:
Given:
The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
Now, to find the percent error.
As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
<em>The actual measure</em> = 2 million.
The estimated measure = 2.5 million.
<em>So, the error</em> = 
Now, to get the percent error:
Therefore, 25% is the percent error.
Step-by-step explanation:
One pound = $0.65
Total cost = c
Number of pounds to ship = p
Part a:
c = 0.65p
When p = 2
c= 0.65(2)
c = $1.30
Part b:
One pound = $0.65 - $0.05 = $0.60
c= 0.6p
Answer: (a) $1.30 (b) c= 0.6p
Answer:
X=80
Step-by-step explanation:
180-100=80
230000÷3.5%=6571%
6571%*15=9857%(be after 15 years)
Answer:
y = 8/3x - 91/3
*view attached graph*
Step-by-step explanation:
3x +8y =4
-3x -3x
8y = -3x + 4
/8 /8
y = -3/8x + 1/2
Perpendicular lines have reciprocal slopes. So, the slope of -3/8 will now be 8/3
y = mx + b
y = 8/3x + b
-9 = 8/3(8) + b
-9 = 64/3 + b
3(-9 = 64/3 + b)
-27 = 64 + 3b
-64 -64
-91 = 3b
/3 /3
-91/3 = b
y = 8/3x - 91/3
Check your answer using (8, -9):
y = 8/3x - 91/3
-9 = 8/3(8) - 91/3
-9 = 64/3 - 91/3
-9 = -27/3
-9 = -9
This statement is true.
Hope this helps!
