The Ruiz family is exchanging euros for US dollars. The exchange rate is 1 euro equals 1.35261 USD. Since the Ruiz family knows

No, it should not give exactly the right amount because numbers will have to be rounded because US dollars only go to the hundredths place making the final number slightly different than the exact value would be.

Meg initially has 3 hours of pop music and 2 hours of classical music in her collection. Every month onwards, the hours of pop m

zlopas [31]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Number of hours of pop music = 3

Number of hours of classical music = 2

According to question, Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change.

Rate of increment = 5% = 0.05

Let the number of months be 'x'.

So, our required function becomes,

$f(x)=3(1+0.05)x+2\\\\f(x)=3(1.05)x+2$

Hence, Option 'd' is correct.

For 113 consecutive days, a process engineer has measured the temperature of champagne bottles as they are made ready for servin

RideAnS [48]

Answer:

upper control limit $UCL=7.1632$

Concept :

$UCL=\bar{\bar{x}}+A_2\bar{R}$ where $A_2=0.34$

$\bar{\bar{x}}=\frac{\bar{x}}{n}$

$S=\frac{\bar{R}}{d}\Rightarrow \bar{R}=S\times d$ where $S=0.5, d=2.97$

Given :

She took a sample of per day $(n)$ is $9$ bottles.

The standard deviation $S$ of all bottles is $0.5$ degree.

Average across all $1017$ bottles $\bar{x}$ are $60$ degree Fahrenheit.

To find :

The value of the upper control limit (UCL)

Explanation :

Here, firstly we find the value of $\bar{\bar{x}}$ .

$\because\bar{\bar{x}}=\frac{\bar{x}}{n}$

$\therefore \bar{\bar{x}}=\frac{60}{9}$

$\Rightarrow \bar{\bar{x}}=6.66$ and $\bar{R}=S\times d$

$\Rightarrow \bar{R}=0.5\times2.97=1.48$

$\Rightarrow \bar{R}=1.48$

Now, $UCL=\bar{\bar{x}}+A_2\bar{R}$

$\Rightarrow UCL=6.66+0.34\times1.48$

$\Rightarrow UCL=6.66+0.5032$

$\Rightarrow UCL=7.1632$ degrees.
