The exchange rate for converting units of currency X (x) to units of currency Y (y) was y = 1.05x.

Luba_88 [7]

a) For 900 units of currency X, at an exchange rate of y = 1.05x, you could get 945 of currency Y.

b) The inverse function is x is 0.9524y and it represents the conversion of units of currency Y to units of currency X.

c) For 46 units of currency Y, at the exchange rate of x = 0.9524y, you could get 43.81 of currency X.

<h3>What is an exchange rate?</h3>

An exchange rate is a value that a currency has with another.

The exchange rate shows the proportion or ratio at which two currencies are exchanged.

<h3>Data and Calculations:</h3>

The exchange rate of X (x) to Y 9y) is y = 1.05x.

For 900 units of currency X, you could get 945 of currency Y (1.05 x 900)

The inverse function is x = 0.9524y (900/945)y

For 46 units of currency Y, you could get = 43.81 of currency X (0.9524 x 46).

If one dozen of note books note books cost Rs. 252. Find the cost of 10 note books ?

lukranit [14]

Step-by-step explanation:

$\underline {\underline{ \text{Given}}} :$

Cost of one dozen of note books ( 12 note books ) = Rs 252

$\underline{ \underline{ \text{To \: find}}} :$

Cost of 10 note books

$\underline{ \underline{ \text{Solution}}} :$

Finding the cost of 1 note book :

⟼ $\tt{ \frac{252}{12} = Rs 21}$

Finding the cost of 10 note books :

⟼ $\tt{21 \times 10 = Rs 210}$

$\pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{Rs 210}}}}}}}$

Hope I helped ! ツ

Have a wonderful day / night ! ♡

In statistics, what term means "a numerical range around a sample mean accompanied with a statement of how confident one is that

Alex Ar [27]

Answer:

Confidence Interval for the mean

Step-by-step explanation:

Confidence interval is made using the observations of a sample of data obtained from a population, so it is constructed in such a way, that, with a certain level of confidence (this is the statement mentioned in the question), that is, one could have a percentage of probability that the interval, or range around the value obtained, frequently 95%, contains the true value of a population parameter (in this case, the population mean).

It is one way to extract information from a population using a sample of it. This kind of information is what inference statistic is always looking for.

An approximation about how to construct this interval or range:

Select a random sample.
For the specific case of a mean, you need to calculate the mean of the sample (sample mean), and, if standard deviation is unknown or not mentioned, also calculate the sample standard deviation.
With this information, and acknowledged that these values follows a standard normal distribution (a normal distribution with mean 0 and a standard deviation of 1), represented by random variable Z, one can use all this information to calculate a confidence interval for the mean, with a certain confidence previously choosen (for example, 95%), that the population mean must be in this interval or range around this sample mean.
