Answer: The probability is zero.
Step-by-step explanation:
The labels on the 4 cards are 1, 3, 5 and 7. Because the cards are equal, the probability of dragging at random each one of them is equal to 1/4 = 0.25.
Now, the probability that Tim selects a card labeled with a 4 is equal to the number of cards labeled with a 4, divided the total number of cards.
We do not have cards labeled with a 4, so the probability is:
p = 0/4 = 0
because we do not have any card labeled with a 4, the probability of selecting one at random is equal to zero.
Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0

The <u>whole number</u> <u>closest </u>to √22 is 5.
The square root of 22 is:
= √22
= 4.69
The whole number that it is closest to will <u>depend on the first decimal point</u>.
If it is 5 or above then it will be closest to 5.
If it is 4 and below, then it is closest to 4.
The first decimal point is 6 so √22 is closer to 5.
In conclusion, the square root of 22 is closer to 5.
