Median- 23
Mode- 12
Answer:
Step-by-step explanation:
<u>Problems given:</u>
- - 2000 + 20.5 = - 1979.5 ≈ -1980.0 ⇒ 3 significant figures
- - 106.2 + 54.07 = - 52.13 ≈ -52.1 ⇒ 3 significant figures
Zeros at the end are not counted as significant figures
Answer:
y=-4x+2
Step-by-step explanation:
The slope intercept form is: y=mx+b
Then
y=-4x+b
y=2 and x=0 at the intercept
thus
2=-4(0)+b
b=2
y=-4x+2
Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders
Answer:
4=1
Step-by-step explanation:
2(n + 2) = 4n + 1 - 2n
2n + 4 =4n - 2n + 1
2n + 4 = 2n + 1
<em>add -2n to each side</em>
2n-2n+4=2n-2n+1
0+4=0+1
4=1
idk if this is right myself but this is want i found on internet, i searched it up for 1 hour and this is the ans they gave me...
