Let's try to simplify x^2 + 16. It's a sum of two squares:
x^2 + 16 = 0
x^2 = -16
The problem is, we can't take a square root of a negative. This is where imaginary numbers come in.
Remember that square roots have a plus or minus symbol outside:
±√-16 = ±4i
Our two roots are 4i and -4i. Therefore, the trinomial simplifies to:
(x + 4i)(x - 4i)
If we attempt to divide x + 4 by these two binomials, we will find that 4 and 4i are not like terms. Therefore, we can't simplify this expression.
Answer:
-60/7 or -8 4/7 would be the answer
Answer:
c. 3324
Step-by-step explanation:
We need to use the formula of Geometric CDF with π =0.02
P(x≤20) = 1 - (1-0.02)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - 0.6676
P(x≤20) = 0.3324
Therefore the probability that the first such ejection occurs within the first 20 Visa transactions is 0.3324
30 % of students because add 9% to 61% thats how i got it i think is wrong dont know
Answer:
The correct expression is n + 8
The value of the expression = 5.3 + 8
The answer is 13.3
Step-by-step explanation:
The expression for eight increased by a number
Assume that the number is n
Increased eight by n means add n to eight
The correct expression is n + 8
When n = 5.3
Substitute 5.3 for the variable n
The value of the expression = 5.3 + 8
Simplify by adding 5.3 and 8
5.3 + 8 = 13.3
The answer is 13.3
