what does it look like first
Well, since these are rectangles, and both have 2 measurements, it would be quite simple, you must find how 9 and 15 are similar, then see if that same similarity is found within the 3 and the 5.
the answer is yes, they are similar because...
9×1 1/3=15
and
3× 1/3=5
therefore they are similar.
hope this helped, plz follow me
Here are two slightly different ways to look at it.
Both ways do exactly the same thing.
<u>Way #1:</u>
Divide (the new number) by (the old number)
349 / 320 = 1.090625
Change the quotient 1.090625 to percent.
To change any number into percent, multiply it by 100, or move the decimal point 2 places to the right.
1.090625 ==> 109.06 %
The new number (349) is 109.06% of the old number (320).
But the old number was 100% of itself. So the new number
is <em>9.06% more</em> than the old number was.
================================
<u>Way #2:</u>
How much bigger is the new number ?
(349 - 320) = 29 bigger
Divide the increase by the old number:
29 / 320 = 0.090625
Change the quotient to a percent.
0.090625 = 9.06%
The <em>increase</em> is<em> 9.06%</em> of the old number.
Answer:
Option A - 4.91
Step-by-step explanation:
The formula for theoretical standard deviation of uniform distribution is;
σ = √{(b-a)^2}/12
Now from the question, b = 38 minutes and a= 21 minutes
Therefore, σ = √{(38-21)^2}/12
= √{17^2}/12 = √289/12 = 4.907 which is approximately 4.91
Answer:
d
Step-by-step explanation:
Note that
> means greater than
< means less than
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
To determine which comparison is better we have to convert litre to millimetre
1 litre = 1000mm
A 5 mm > (50 x 1000)
5 mm > 50,000
5 is not greater than 50,000
B. (2 x 1000) < 200 mm
2000 < 200
2000 is not less than 200
C. (100 x 1000) < 1,000
100,000 < 1000
100,000 is not less than 1000
D. 3200 > (3 X 1000)
3200 > 3000
3200 is greater than 3000
