C) 239.99 * 0,4 = 95.99.
We multiply by 0.4 because when you remove 60% from the price, you are left with 40% or 0.4.
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following:
Then we will substitute in the following formula:
Students who play soccer=Number of students*(Probability that they play soccer)
Replacing:
Students who play soccer=300*(12/25)
Students who play soccer=3600/25
Students who play soccer=144
Finally we obtain that 144 students would we expect to play soccer, based on Sean's experiment.
Answer:
21 divided by 2 and 2/3 = 11.1666667
Step-by-step explanation:
Answer:
b = 3/8
Step-by-step explanation:
Solve for b:
b + 1/8 = 1/2
Put each term in b + 1/8 over the common denominator 8: b + 1/8 = (8 b)/8 + 1/8:
(8 b)/8 + 1/8 = 1/2
(8 b)/8 + 1/8 = (8 b + 1)/8:
(8 b + 1)/8 = 1/2
Multiply both sides of (8 b + 1)/8 = 1/2 by 8:
(8 (8 b + 1))/8 = 4
(8 (8 b + 1))/8 = 8/8×(8 b + 1) = 8 b + 1:
8 b + 1 = 4
8/2 = (2×4)/2 = 4:
8 b + 1 = 4
Subtract 1 from both sides:
8 b + (1 - 1) = 4 - 1
1 - 1 = 0:
8 b = 4 - 1
4 - 1 = 3:
8 b = 3
Divide both sides of 8 b = 3 by 8:
(8 b)/8 = 3/8
8/8 = 1:
Answer: b = 3/8
The values of tan x is undefined for odd number multiples of x.
Thus, the values of tan x is undefined for x = . . . -3(90), -1(90), 1(90), 3(90), . . .
Therefore, the values of x for which tan (x) is undefined are <span>-270°, -90°, 90°, and 270°</span> [option A].
