Answer

t = 2

Step-by-step explanation

Simplify 5-(t+3).

-t+2=-1+2t-3

Subtract 3 from -1

-t+2=2t-4

Move all terms containing to the left side of the equation.

-3t+2=-4

Move all terms not containing t to the right side of the equation.

-3t=-6

Divide each term by -3 and simply.

t = 2

mario62 [17]

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

Lapatulllka [165]

Answer:

Max is currently 12 years old.

Step-by-step explanation:

Zeke's current age = 8 years

Lets take Max's current age as $x$ years.

Then Max's age 3 years ago = $x-3$

Double Max's age 3 years ago = $2*(x-3)$

Double Max's age 3 years ago + Zee's current age = 26

⇒ $2*(x-3)$ + $8$ = $26$

= $2*(x-3)+8=26$

= $2x-6+8=26$ (Simplifying the brackets)

= $2x+2=26$

= $2x+2-2=26-2$ $2x=24=$ $x=12$

So Max's current age is 12 years.

How many g of amino acids are in a 2,000mL total parenteral nutrition of 4.25% travesol (amino acids and 20%dextrose?

kirill115 [55]

Answer:

The mass of amino acid present is 85 g

Step-by-step explanation:

From the question we are told that

The volume of the total parenteral nutrition is $V = 2000 mL$

Generally the volume of the amino acid present is

$V_a = 0.0425 * 2000$

$V_a = 85 mL$

Generally

$mass \ \ \alpha \ \ volume$

So the mass of amino acid present is 85g
