Answer:

<em>The probability that code is 14z will be \frac{1}{1300}</em>

Step-by-step explanation:

From 00 to 49, there are total 50 two-digit numbers.

The total number of alphabets is 26.

So, the probability of choosing 14 from all 50 two digit numbers will be:  \frac{1}{50}

and the probability of choosing 'z' from all 26 alphabets will be: \frac{1}{26}

Thus, the probability that code is 14z is = \frac{1}{50}\times \frac{1}{26}=\frac{1}{1300}

AfilCa [17]

The probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen is 0.031 or 3.1%. The events are dependent events.

Given that there are five vowels, which come from the letters A, E, I, O, and U, the likelihood of drawing a vowel is:

5/26

since there are a total of 26 alternatives available. After choosing that, we are left with 25 alternatives, 4 of which are vowels, thus the probability is:

4/25

The final likelihood is thus:

5/26 * (4/25) = 0.031

In other words, the likelihood is 3.1% when choosing a vowel and then another (without replacement).

The first event has an impact on the second event since there are fewer vowels and overall possibilities, hence the events are dependent.

12!/3!13! What does this mean?
AfilCa [17]
12! = 12x11x10x9x8x7x6x5x4x3x2x1 =479,001,600

3! = 3x2x1 =6
13! = 6,227,020,800

6,227,020,800 x 6 = 37,362,124,800

479,001,600/37,362,124,800=0.0128

Find the surface area of a cylinder with the height of 10 inches and a base diameter of 6 in ​
sweet-ann [11.9K]

Answer:

339.24

Step-by-step explanation:

To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2

The radius is half the diameter do r=3

3.14(3)^2 should give you about 28.27.

This is the area of the top and bottom of the cylinder.

Now, do 28.27x10=282.7 to find the height surface area.

282.7+28.27+28.27=Surface area.

SA= about 339.24

tester [92]
Set up a proportion. Let h = the statue height. h/statue shadow = boy height/boy shadow.

h/25 = 4.5/3.6

Cross multiply and solve for h.
