Answer:

a standard crd deck has 52 cars so

the probability of getting red is 0.5 since 2 of the 4 faces are red. The probability for getting a king is 1/13 since there are 13 different card values.

Note:

52 cards in a deck

26 red cards in a deck

4 kings in a deck


Let’s set:

P(A) = drawing a red card
P(B) = drawing a king card

P(A or B) = drawing a red or a king card

P(A and B) drawing a red AND a king card

Formula:
P(A or B) = P(A) + P(B) - (A and B)

Solve:
P(A and B) = 26/52 • 4/52 = 1/26

P(A or B) = 26/52 + 4/52 - 1/26 = 7/13

Your answer is 7/13.



(I hope I’m correct)

Naddika [18.5K]

Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 )  = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ  ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725  

<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>

p ( X < 725 ) = p (( X - μ )/ б √n  <  725 - 750 / 55√25 )

                     = P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116  ( using Z-table )

PLS HELP WITH THE QUESTION IN THE PICTURE!!!
Ksivusya [100]

Answer:

D

Step-by-step explanation:

Interesting question.  The wording is a bit awkward. I think you have to assume the base is a square and each succeeding base is also a square.

So the first thing to do is to add the bases together.

30*30 + 23*23 + 16*16 + 9*9

Don't add these -- not yet.

Now take the height into consideration

6 *(30*30 + 23*23 + 16*16 + 9*9)

The point is that you only have to multiply by 6 once.

6*(900 +  529 + 256 + 81)

6*(1766)

10596 cubic inches

The answer is D

luda_lava [24]

The statements are true for the given geometric sequence.

The domain is the set of natural numbers.

The recursive formula representing the sequence is f(x + 1) = 3/2(f(x )) when f(1) = 4.

The sequence shows exponential growth.

We have given the graph.

What is the geometric sequence?

A geometric sequence is a sequence in which the ratio of every two successive terms is a constant.

The graph is given below we can see that

The domain is the set of natural numbers.

The recursive formula representing the sequence is
