Answer:

$mu=12.1299$

$\sigma=1.2987$

Step-by-step explanation:

In the normal distribution curve, we will have 5% below 10 months [horizontal axis] and 75% below 13 months [horizontal axis].

We need to find z-score using z-table [normal table] that corresponds to

5% = 0.05

and

75% = 0.75

Zscore formula:

$z=\frac{x-\mu}{\sigma}$

Where mu is mean and sigma is standard deviation [these are the 2 parameters we are seeking]

So, 0.05 corresponds to z = -1.64, and

0.75 corresponds to z = 0.67

Now we put both of these into z-score formula and solve both equations for mu and sigma.

$-1.64=\frac{10-\mu}{\sigma}$

and

$0.67=\frac{13-\mu}{\sigma}$

The first equation becomes:

$-1.64=\frac{10-\mu}{\sigma}\\-1.64\sigma+\mu=10\\mu=10+1.64\sigma\\$

Now, simplifying 2nd equation and putting this in:

$0.67=\frac{13-\mu}{\sigma}\\0.67\sigma=13-(10+1.64\sigma)\\0.67\sigma=13-10-1.64\sigma\\2.31\sigma=3\\\sigma=1.2987$

Now finding mu:

$\mu=10+1.64(1.2987)\\\mu=12.1299$

These two MU(mean) and SIGMA(standard deviation) are the 2 parameters.

In a set of 24 cards, each card is numbered with a different positive integer from 1 to 24. One card will be drawn at random fro

pentagon [3]

Answer:

$P_{f} = \frac{7}{24}$

Step-by-step explanation:

Considering that the set has 24 cards on it, numbered from 1 to 24 inclusive, it means that the total number of cases is 24. Now, we have to find the number of favorable outcomes.

Cases where the number is divisible by both 2 and 3:

In the interval 1 to 24 inclusive, $[1,24]$ :

Numbers divisible by 2 => 2 4 6 8 10 12 14 16 18 20 22 24

Numbers divisible by both 2 and 3 => 6 12 18 24

Which means that there are 4-favorable outcomes for this scenario.

Cases where the number is divisible by 7:

In the interval 1 to 24 inclusive, $[1,24]$ :

Numbers divisible by 7 => 7 14 21

Which means that there are 3-favorable outcomes for this scenario.

The total number of favorable outcomes is $4 + 3 = 7$ . Since the total number of cases is $24$ , the probability of favorable outcomes, $P_{f}$ , is:
