Answer:
The size of the tank is 16 gallons
Step-by-step explanation:
Here, we want to calculate the size of the gas tank of the truck
we simply divide the total amount spent by the price per gallon
Mathematically, that will be;
53.28/3.33 = 16 gallons
By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8
The answer is the option D.
You have to use implicit derivative
1) dy / dx = y'
2)
Average means add eveybody and divide by how many there are
5 lants
(4+3.5+4.5+4.2+3.8)/5=4
average is 4
dunno standard deviation
