1 L, or 1000 mL, of the drink contains 360 mL juice. If there is a total of 1600 mL, we have 360/1600=9/40 (or .225) as the concentration of juice.
Answer:
Step-by-step explanation:
We can use combinations
20 choose 4:
20!/(16!*4!)
= (20*19*18*17)/4!
= 4845

➷ Find the total of frequencies rolled over 10 (this would be 11 and 12)
15 + 17 = 32
Place this number over the total number of trials:
32/200
This can be simplified to 4/25

Answer:
second option
Step-by-step explanation:
Given
a(c + b) = d ← distribute parenthesis on left side
ac + ab = d ( subtract ab from both sides )
ac = d - ab ( isolate c by dividing both sides by a )
c = 
Answer:
-1<-0.25
With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong
Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.
