Answer:

The probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$ is : $P[|\bar{x}-\mu|\leq0.7]=0.9876$

Step-by-step explanation:

Given :

Population standard deviation $\sigma=2.8$ .

Sample size $n=100$

The sample mean standard deviation $=\frac{\sigma}{\sqrt{n}}$

To find :

The probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$

$\because\frac{\sigma}{\sqrt{n}}=\frac{2.8}{\sqrt{100}}=\frac{2.8}{10}=0.28$

Now, the probability that the difference between the sample mean $\bar{x}$ and the true population mean $\mu$ is :

$P[|\bar{x}-\mu|\leq0.7]$ , $n$ is large $\Rightarrow \frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}=z$

$\Rightarrow P[\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}$

$\Rightarrow P[z$

$\Rightarrow P[-2.5$

Therefore, the probability $P[|\bar{x}-\mu|\leq0.7]=0.9876$

To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction proper

Answer:

The value of <em>x</em> is $-\frac{28}{5}$ .

Step-by-step explanation:

The distributive property is:

a (b + c) = a · b + a · c

The expression is:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

Solve using the distributive property as follows:

$3(\frac{1}{3}x+1)+4=-1-4(x+3)-3$

$(3\cdot \frac{1}{3}x)+(3\cdot 4)=-1-(4\cdot x)-(4\cdot 3)-3\\\\x+12=-1-4x-12-3\\\\x+4x=-16-12\\\\5x=-28\\\\x=\frac{-28}{5}$

Thus, the value of <em>x</em> is $-\frac{28}{5}$ .
