Answer:
a) The unit rate of change of d with respect to t is equal to 1.6
b) the graph of the line in the attached figure.
We know that one coin has 2 sides, this makes it so the expression is 2 multiplied by x, or 2x
Answer:
Step-by-step explanation:
we will remove the parenthesis
2.75x+0.25x+1-x+3.8=
=2 x+4.8
choice A
Answer:
The value of P( A and B ) is 0.08.
Step-by-step explanation:
When two events are independent then the probability of both occurring is equal to the product of probabilities of both events individually,
That is, If X and Y are independent events,
Then, P(X∩Y) = P(X) × P(Y),
or P(X and Y) = P(X) × P(Y),
Here, P(A) = 0.40 and P(B) = 0.20,
Hence, P(A∩B) = P(A) × P(B)
= 0.40 × 0.20
= 0.08
