The nicotine content in a single cigarette of a particular brand has a distribution with mean 0.4 mg and standard deviation 0.1
a_sh-v [17]

Answer:

Step-by-step explanation:

For this case we can define the random variable of interest as: "The nicotine content in a single cigarette " and for this case we know the following parameters:

\mu = 0.4, \sigma = 0.1

And for this case we select a sample size of n =100 and we want to find the following probability:

P(\bar X

And for this case we can use the z score formula given by:

z =\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z= \frac{0.38-0.4}{\frac{0.1}{\sqrt{100}}}= -2

And we can find the required probability with the normal standard table and we got:

P(z

Paul has $40000 to invest. His intent is to earn 9% interest on his investment. He can invest part of his money at 6% and part a
Black_prince [1.1K]

Paul needs to invest $10000 at 6% interest and $30000 at 10% interest to make a total of 9% return on his $40000.

<em><u>Explanation</u></em>

Suppose, the amount of money at 6% interest is x

As Paul has total $40000 to invest, so the amount of money at 10% interest will be: (40000-x) dollar

His intent is to earn 9% interest on his $40000 investment. So, the equation will be......

0.06x+0.10(40000-x)=0.09*40000\\ \\ 0.06x+4000-0.10x=3600\\ \\ -0.04x=3600-4000=-400\\ \\ x=\frac{-400}{-0.04}=10000

So, Paul needs to invest <u>$10000 at 6% interest</u> and ($40000- $10000) or <u>$30000 at 10% interest </u>to make a total of 9% return on his $40000.

Because of the commutative property of multiplication, it is true that
rewona [7]

Answer:

It is Commutative

Step-by-step explanation:

An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.

Given the operation ∆ defined by:

a∆b=a X b

a=\frac{3}{4}, b=4

a∆b=\frac{3}{4}X4

=\frac{3X4}{4}=3

Similarly, for the right hand side.

(\frac{4}{3})^{-1}=\frac{3}{4}

Therefore:

b∆a=4X \frac{3}{4}

=\frac{4X3}{4}=3

These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:

a∆b=b∆a=3
