A punch contains 60% of grape juice and the rest is lemon - lime soda ( 2 liters).
Part A:
An equation is:
0.6 x + 2 = x,
where x stays for the liters of punch.
Part B:
x - 0.6 x = 2
0.4 x = 2
x = 2 : 0.4
x = 5 liters
Grape juice = 5 - 2 = 3 liters.
Answer: There are 3 liters of grape juice in the punch.
Answer:
120 , 300 degrees ( for angles between 0 and 360 degrees).
In radians this is 2π/3, 5π/3 radians.
Step-by-step explanation:
Arctan ( - sq rt 3) is the angles ( in radians or degrees) for which the tangent is - sq rt 3.
Arctan sq rt 3 = 60 degrees or π/3 radians.
As the tangent is negative in the 2nd and 4th quadrants arctan(-sq rt 3) = 120 , 300 degrees.
Answer:
8
Step-by-step explanation:
In a randomnized block design, the formula for calculating the degrees of freedom for error is given by:
(r-1)(c-1)
where: r is the number of treatments and c is the number of blocks
Applying the above formula to this case;
The number of treatments is 5 and the number of blocks is 3, which means we can calculate the degrees of freedom for error as :
(5-1)x(3-1) = 4 x 2 = 8

Answer:
Not independent
Explanation:
Two events are not independent/dependent if the result of one event affects the outcome of the other. In the case above, numbers are picked without replacement, therefore if one slip is picked then the other slip will be picked(slips are picked only once not twice or more as in independent events). Events would be independent if there was a replacement.
