Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- Apply the Distributive property.
- Remember that, according the exponents properties, when you multiply two powers with equal base, you must add the exponents.
- Add the like terms.
Therefore, you obtain that the product is the following:

Answer
125
Explanation
5 • 10^6 = 5,000,000
4 • 10^4 = 40,000
5,000,000 / 40,000 = 125
Answer:
The probability that the student is going to pass the test is 0.0545
Step-by-step explanation:
The variable that says the number of correct questions follows a Binomial distribution, because there are n identical and independent events with a probability p of success and a probability 1-p of fail. So, the probability of get x questions correct is:

Where n is equal to 10 questions and p is the probability of get a correct answers, so p is equal to 1/2
Then, if the student pass the test with at least 8 questions correct, the probability P of that is:
P = P(8) + P(9) + P(10)

P = 0.0439 + 0.0097 + 0.0009
P = 0.0545
Answer:Explained
Step-by-step explanation:
Given
One shirt cost $24.97 and other costs $13.75
Using mental math, Payton rounds $24.97 to $25
and add it to $13.75 to get $38.75
in order to get correct total of two shirts Payton needs to subtract $0.03 from the final amount as she round 0.97 to 1 initially
so final amount will be 38.75-0.03=$38.72
