Misha Larkins [42]

Answer: 120 Packages

Step-by-step explanation:

Given

75 random packages are check

3 package is found faulty

So, the percentage of error is

$\Rightarrow \dfrac{3}{75}\times 100=4\%$

i.e. 4% packages is faulty

For 3000 sample, expected faulty packages are

$\Rightarrow 3000\times \dfrac{4}{100}=120\ \text{Packages}$

Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequ

slega [8]

The general form of the geometric sequence is $a_{n} = a_{1} (r) ^{n-1}$ , where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1. Our formula then looks like this: $a_{10} =-6(2) ^{10-1}$ . Simplify it to $a_{10} =-6(2)^9$ . Take 2 to the 9th power then multiply it by -6 to get -3072. C is your answer.

(20 points) Simplify The Expression with work/steps<br><br> (8+3i) + (-2+ i)

zimovet [89]

Given the expression (8+3i)+(-2+i)

We need to simplify it.

(8+3i)+(-2+i)

First we have to remove the parenthesis.

8+3i-2+i

As we know that multiplication of positive and negative is negative.

Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.

8-2 +3i+i

6+4i

We have got the required answer.

The simplified answer is 6+4i.
