Answer:
27%
Step-by-step explanation:
Jaylon spent 27% of his birthday money.
Will Smith paid $857.19 for the 60 inch TV.
Step-by-step explanation:
Step 1:
The 60 inch TV sells for $1,250. The electronics store offers a discount of 35%.
So the price that is paid for the TV is reduced by 35%.
We need to determine how much 35% of $1,250 is.
35% of $1,250
So a discount of $437.50 is applied to the original price.
The discounted price
The discounted price of the TV is $812.50.
Step 2:
A sales tax rate of 5.5% is applied where Will Smith lives.
We need to determine how much 5.5% of $812.50 is.
5.5% of $812.50
So a sales tax of $44.6875 is applied to the original price.
The total price
Rounding this off, Will Smith paid $857.19 for the 60 inch TV.

Answer:
a.0.3020
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they have experienced feeling of math anxiety, or they have not. The students are chosen at random, which means that the probability of a student having experienced feelings of math anxiety is independent from other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
20% of the students have experienced feelings of math anxiety.
This means that
If you take a random sample of 10 students from this population, the probability that exactly 2 students have experienced math anxiety is
This is when
So the correct answer is:
a.0.3020
