If you would like to solve <span>2/5 * (15x - 20) = 3 * (3x - 4), you can do this using the following steps:
</span>2/5 * (15x - 20) = 3 * (3x - 4)
6x - 8 = 9x - 12
-8 + 12 = 9x - 6x
4 = 3x
x = 4/3 = 1 1/3
The correct result would be 4/3.
Answer:
Perimeter of a triangle = 2*(length + breadth)
SO = 2*18+41
= 77 is the perimeter
Answer: yes
Step-by-step explanation: 11x6=66 books
Simply using the given formula ,
I = P × R × t
I = 100 × 10/100 × 3
I = $30
First problem:
The answer is C because theoretically it should have a 50% of landing
heads but instead it lands heads 56% of the time. Thus this is 6% higher
than 50%. It's not D because there is not specified detail of how the
person got this data so you can assume that the person did a fair
survey/data collection.
Second problem:
So in a data size of 490, 140 of them we trout. This means that 140/490 or 28.57% of the fish are trout. This means that in a sample size of 5000 fish, 5000*0.2857 or 1428.57 are trout.
Third problem:
The Science students seem to have a higher average score because the average score of Math students are:
(32+33+34+34+35+37+39+40+40)/9=36
average score of Science students are:
(41+42+43+43+46+46+47+49+49)/9=45.111
