Answer:
3√2
Step-by-step explanation:
1(3√2)2=2n
Multiply 2 and 1 to give 2
2(3√2)=2n
Multiply 2 and 3√2=6√2
6√2=2n
Divide both sides by 2
n=6√2/2=3√2
Answer:
6 inches long and 4 inches wide
Step-by-step explanation:
The dimensions of the actual crate are 20 times those on Jacob's drawing. The dimensions on the builder's drawing are 1/10 of those, so (1/10)(20) = 2 times the dimensions on Jacob's drawing.
The dimensions on the builder's scale drawing are 6 inches long by 4 inches wide.
Take away 1 from either side so the equation becomes 63=3x then divide both sides by 3 so it becomes 21=x which is your answer (option A)

(a)In this region, are the events "silver" and "black" mutually exclusive:? Choose 1 answer
(A) Yes (B) No
(b) Find the probability that a randomly selected car from this region is mainly silver OR mainly black. P (silver OR black)=
Answer:
(a)Yes
(b)0.41
Step-by-step explanation:
(a) The events silver and black are mutually exclusive. Although a car's color can consist of both silver and black, its main color can only be either silver or black. It cannot be both
(b)In probability theory, given two mutually exclusive events A and B.
P(A or B)=P(A)+(B)
Therefore:
P (silver OR black)= P(silver) + P(black)
= 0.22 + 0.19
= 0.41
