Answer:
The expected value of the number of spades are = 4.25
Step-by-step explanation:
As per the question,
W know that in a standard deck of 52 playing card, there are 4 suits, and each suit have 13 playing card.
Since, we know that
Therefore,
Probability of any random card being a spade is
So the expected number of spades we draw are
Hence, the expected value of the number of spades are = 4.25
Answer:
A(-7,2)
Step-by-step explanation:
Answer:
B. y = |2x| - 2.
Step-by-step explanation:
If we start with y = 2x:
this passes through the origin and has a slope of 2.
y = |2x| means the absolute ( positive) values only, so the part of the line below the x axis is reflected in the axis to form a V shaped graph.
So we have a V shaped graph with the vertex at (0, 0).
Then -2 brings the vertex from (0, 0) to (0 -2) so we get:
y = |2x| - 2.
For the first one, the two in the middle apply. for the second one, they all apply
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equations :
6.01 × □ = 601 No 0.305 × □ = 305 No 0.54 × □ = 540 No 0.097 × □ = 970 Yes
Will the number 103 will make each true?
601 / 6.01= 100 (No, not true)
305 / 0.305 = 1000 (No, not true)
540 / 0.54 = 100 (No, not true)
970 / 0.097 = 10000 (No, not true)
Hence, multiplying each of the equation above by 103 will not make any of the equations true.
