There are 10 juice boxes in the cooler altogether.
2 of them are grape.
The first time Jill pulls one out with her eyes closed,
the probability that it's a grape is
2 / 10 .
If that try is successful, then there are 9 boxes left in the cooler,
and one of them is grape.
If she already has one grape, and reaches in again with her eyes
closed, the probability of pulling out the second grape is
1 / 9 .
The probability of both events happening in two tries is
(2/10) x (1/9) = 2/90 = 1/45 = (2 and 2/9) percent .
Wrapping paper design with the elements numbered bisected angle
Answer:
3√3+4
Step-by-step explanation:
Given the vectors u = <√3, -1> and v = <3, -4>
u · v = <√3, -1> *<3, -4>
u · v = 3√3 + (-1*-4)
u · v = 3√3+(4)
u · v = 3√3+4
Hence the dot product is 3√3+4
(-4,5) is the correct answer because it needs to be (-y,x) meaning the original x value stays the same because we’re going backwards and the y value changes signs
