I also had to do this. So I am pretty sure the answer should be A.
I think this because if there is linear lines do intersect but no linear no lines intersect. Very sorry if I’m wrong.
That statement would be best express by " x + 25 < 75 ". Since the statement says the sum of x and 25, thus, it will be x + 25. Then it also states that the sum is less than 75, so the best expression would be " < 75".
Answer:
B
Step-by-step explanation:
5x² - 3 - (x² - 4x - 8)
5x² - 3 - x² + 4x + 8

Answer:
13
Step-by-step explanation:
To obtain a term in a Fibonacci sequence, add the previous 2 terms, thus
7 th term = 8 + 5 = 13
Answer:
81 / 1024
Step-by-step explanation:
Given that :
Wheel is divided into 4:
Hence, probability of winning either 10%, 20%, 30% or 50% = 1/4
Probability of winning 50% discount = 1/4
Probability of not winning 50% discount :
1 - 1/4 = (4 - 1) /4 = 3/4
Hence, probability that 50% is won by 5th customer :
(3/4) * (3/4) * (3/4) * (3/4) * (1/4)
= (3/4)^4 * (1/4)
= (81 /256) *(1/4)
= 81 / 1024
