You ask a friend to think of a number from 7 to 14. What is the probability that his number will be an even number? Answer as a

8_murik_8 [283]

Answer:

1/2

Step-by-step explanation:

Not sure but

I am assuming we have 8 integers :

All or (A) = {7,8,9,10,11,12,13,14} = n(A) = 8

Hence, the probability of any one outcome is 1/8.

Therefore, as you can detect, there are 4 numbers that are even numbers which means :

Even or (E) = {8, 10, 12, 14} = n(E) = 4

So, let E imply this occurrence

E x A

= 4 x 1/8

= 4/8

= 1/2

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13 x = 13

cos45 = 13/y y = 13√2

12) sin30 = 4/x x = 8

tan30 = 4/y y = 4√3

13) sin60 = 21/x x = 21(2/√3) = 42/√3

y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22 x = 22/√2

sin45 = y/22 y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x x = 12/√2

tan45 = y/12 y = 12

cos30 = z/24 z = 24(√(3)/2) = 12/√3

One coastal cholla cactus can house the nest of the cactus wren containing two adults and up to five young. Six cholla cacti are

saveliy_v [14]

Answer:

The maximum number of wren that could nest in the area based on the number of cholla cacti is:

42 wrens.

Step-by-step explanation:

The information provided by the text mentions that each cholla cactus can house a nest in which two adults and a maximum of five young will live (seven in total per nest), so this information can be represented as follows:

Maximum number of wrens = number of cholla cactus * 7

Since six cholla cacti are counted in the area, this value is replaced in the created equation:

Maximum number of wrens = 6 * 7
Maximum number of wrens = 42

The area could house a maximum of 42 wrens, where 12 would be adults and 30 would be young at most.
