(5x+4)(5x-4) using FOIL method, multiply the terms in the binomials

Mathematics
1 answer:
Ksju [112]3 years ago
3 0

Answer:

25x^2 - 16.

Step-by-step explanation:

(5x+4)(5x-4)

F = 5X*5X = 25X^2

O = 5x * - 4 = -20x

I = 4 + 5x = 20x

L = +4 * -4 = -16

So its

25x^2 - 20x + 20x - 16

= 25x^2 - 16.

In an EFE​ Matrix, how much more important is a weight of 0.20 than a weight of​ 0.15? A. ​50% B. ​33% C. ​25% D. ​.05% E. ​5.0%
sergij07 [2.7K]

Answer:  B. ​33%

Step-by-step explanation:

  • In Mathematics , a percentage is basically a process of dividing the numerator by the denominator , then multiply the answer by 100.

We use Mathematical Formula : \dfrac{\text{Difference between the Weight of 0.20 and Weight of 0.15 }}{\text{Weight of 0.15}}\times100

Since , Difference between the Weight of 0.20 and Weight of 0.15  = 0.20-0.15=0.05

Then, substitute the value in formula , we get

=\dfrac{0.05}{0.15}\times100\\\\=\dfrac{5}{15}\times100\\\\ \dfrac{100}{3}\%\approx33\%

Hence, the weight of 0.20 is 33% more important than a weight of​ 0.15.

which distribution(s) is/are often used to model the elapsed time between the occurrence of successive events for a poisson rand
11111nata11111 [884]

The required Poisson distribution used to model the elapsed time between the occurrence of successive events for a poisson random variable

<h3>How to find model of Poisson distribution?</h3>

We have to find distribution model used to model elapse the time between the occurrence of successive events for Poisson random variable.

<h3>According to given data in the question:</h3>

we know that, Poisson distribution

P(x=x) = e^-λ(λ)^x/x!

Time between succeess,

P(y>x) = e^-λy

and, P(y<x) = 1- e^-λy

They are exponential distribution.
