Answer:
mass of solution = mass of sugar / concentration
mass of water = mass of solution - mass of sugar
Answers for 50%
mass of solution = 0.5 lbs / 50% = 0.5 lbs / 0.5 = 1 lbs syrup
mass of water = 1 lbs - 0.5 lbs = 0.5 lbs of water
Answers for 5%
mass of solution = 0.5 lbs / 0.05 = 10 lbs syrup
mass of water = 10 lbs - 0.5 lbs = 9.5 lbs of water
Answers for 75%
mass of solution = 0.5 lbs / 0.75 = 0.6667 lbs syrup
mass of water = 0.6667 lbs - 0.5 lbs = 0.1667 lbs of water
Answers for 1.5%
mass of solution = 0.5 lbs / 0.015 = 33.33 lbs syrup
mass of water = 33.33 lbs - 0.5 lbs = 32.83 lbs of water
Answer:
-3/4
Step-by-step explanation:
x - 1 = 5x + 2
or, 5x + 2 = x - 1
or, 5x - x = - 1 - 2
or, 4x = - 3
or, x = - 3 / 4
Answer:
2.C
3.B
4.B
5.D
Step-by-step explanation:
2. the y intercept in this equation is the c value, which is 1 so the answer is c
3. The vertex of this function would be (9, -5) and the axis of symmetry is the first value so its 9, B
4. Not that hard, tip is to just distribute in all the answers and see which one gives you the original equation, it is B
5. You solve the original equation by completing the square, if you don't know how to do that look it up. Answer is D
Answer:
0.408
Step-by-step explanation:
Answer: 0.26
Step-by-step explanation:
As per given , we have
P(green tail) = 0.36
P(red fins) = 0.59
P(both a green tail and red fins ) = 0.21
Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )
<em>[P(neither A nor B)= 1- P(either A or B)]</em>
= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))
<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>
= 1- (0.36+0.59-0.21)
= 1-(0.74)
= 0.26
Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26
