Expand the polynomials and simplify.(0.2x–0.5y)^2

Mathematics
1 answer:
Scilla [17]3 years ago
5 0

Answer: The simplify and expanded form of the polynomial is :

0.04x^2+0.25y^2-0.2xy

Step-by-step explanation:

Since we have given that

(0.2x-0.5y)^2

As we know the formula

"(a-b)^2=a^2+b^2-2ab"

So, we will apply this,

Here,

a = 0.2x

b = 0.5y

So, it becomes,

(0.2x-0.5y)^2\\\\=(0.2x)^2+(0.5y)^2-2\times 0.2x\times 0.5y\\\\=0.04x^2+0.25y^2-0.2xy

Hence, the simplify and expanded form of the polynomial is :

0.04x^2+0.25y^2-0.2xy

How do I make a ten to find the sum
Naddika [18.5K]
Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or ...

A simple random sample of electronic components wil be selected to test for the mean lifetime in hours. Assume that component li
Serjik [45]

Answer:

189 components must be sampled.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.005 = 0.995, so Z = 2.575.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.

This means that \sigma = 16

How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?

n components must be sampled.

n is found when M = 3. So

M = z\frac{\sigma}{\sqrt{n}}

3 = 2.575\frac{16}{\sqrt{n}}

3\sqrt{n} = 2.575*16

\sqrt{n} = \frac{2.575*16}{3}

(\sqrt{n})^2 = (\frac{2.575*16}{3})^2

n = 188.6

Rounding up:

189 components must be sampled.
