Answer:
$6.30 each bottle
Step-by-step explanation:
What you do is you take $4.50 and times it by .40
<em>4.50 x .40 = 1.80</em>
<em>1.80 + 4.50 = 6.30</em>
$6.30 each bottle
he events are not independent
<h3>How to determine if they are mutually exclusive?</h3>
The given parameters are:
P(A) = 0.2
P(B) = 0.2
The events are mutually exclusive.
So, as have
P(A or B) = P(A) + P(B)
If the events are independent, then
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = P(A) * P(B)
So, we have
P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0
P(A and B) = 0.2 * 0.2 = 0.04
The above equations are not equal
Hence, the events are not independent

Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :
So, the dot product of u and v is equal to 2.
