5.2x10^6 is the right answer because the decimal is moved 6 times to the right which makes the 5 the first number because it can’t be more than 10
First multiply it to get how much the discount is
so 94*.15= 14.25 then subtract
94-14.25= 79.75
so Rob spent $79.75 after using his coupon
P.S- That's probably a gold racket! LOL
Answer:
d) 10
Step-by-step explanation:
x ÷ 
+ 8 = 13
substitute 10 for x:
⇒ 10 ÷ + 8 = 13
solve:
1) divide 10 by
⇒ 10 ÷ = 5
2) add 8 to 5
⇒ 8 + 5 = 13

<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
