Answer:
44
Step-by-step explanation:
Gina is four years younger so
18+4=22
since its twice davids age
22×2=44
P(x) = (x^2)(x - 4)^2(x + 4) + some constant(b)
2025 = (1^2)(1 - 4)^2(1 + 4) + b
2025 = 45 + b
b = 1980
Complete Equation:
p(x) = (x^2)(x - 4)^2(x +4) + 1980
or expanded form
p(x) = x^5 - 4x^4 - 16x^3 + 64x^2 + 1980
Answer:
In 8910 ways can at least 4 defective batteries be included in the purchase
Step-by-step explanation:
The order in which the batteries are there is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question:
4 defective:
4 defective from a set of 5 and 2 non-defective from a set of 60 - 5 = 55. So

5 defective:
5 defective from a set of 5 and 1 non-defective from a set of 60 - 5 = 55. So

In how many ways can at least 4 defective batteries be included in the purchase?

In 8910 ways can at least 4 defective batteries be included in the purchase
Hey!
-------------------------------------------------
Steps To Solve:
<em>Remember to follow PEMDAS when solving.</em>
13 + 2(50 - 2) = 29
<em>~</em>Solve what's in parenthesis
13 + 2(48) = 29
~Multiply
13 + 96 = 29
~Add
109 ≠ 29
-------------------------------------------------
Hence, the equation is false.
