So firstly, we have to determine what 6% of $12.50 is. You can do this by multiplying 12.50 and 6% (or 0.06 in decimal form) to get 0.75, or 75 cents. 75 cents is your 6% sales tax.
Next, add up 12.50 and 0.75 to get $13.25. $13.25 is the total cost of the item.

Step-by-step explanation:
Given: 4 - 9x +21
Factorizing this expression, we have;
4 -3(3x - 7)
i. Chang's expression: 4 - 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 -9x -21
ii. Benjamin's expression: 4 + 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 +9x +21
iii. Habib's expression: 4 + 12x
This is not an equivalent expression, because the expression is not related to the given question
Comparing the three student's answers with the appropriate expression, none of the student's is an equivalent expression.
This expression that is equivalent to the given question is;
4 -3(3x - 7) = 4 -9x + 21

Step-by-step explanation:
Answer:
The arc tangent of angle a = (5/7)
angle a = 35.538 Degrees
Of course, we might be solving for angle b so,
angle b = 90 -35.538 Degrees = 54.462 Degrees
Step-by-step explanation:
The probability of at most three boys in ten births is approximately 0.17139, or about 17.14%.
It is a branch of mathematics that deals with the occurrence of a random event.
This is a binomial probability problem with n = 10 (number of births) and p = 0.5 (probability of a boy or a girl).
We want to find the probability of at most three boys in ten births, which is equivalent to finding the probability of 0, 1, 2, or 3 boys.
To calculate this probability, we can use the binomial probability formula:
P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= 0.00098 + 0.00977 + 0.04395 + 0.11719
= 0.17139
Therefore, the probability of at most three boys in ten births is approximately 0.17139, or about 17.14%.
