While cleaning, Tim discovers eighteen decks of standard playing cards (each deck has 52-cards composed of 13 hearts, clubs, dia

monds, and spades). For this problem use the following value assignment Ace = 1, Jack = 11, Queen =12, and King = 13. a) Tim randomly selects 22 cards from one of the decks. If we let X denote the number of cards in Tim's hand that have a value greater than 5. Determine the distribution, parameter(s), and support of X. b) Determine the probability that Tim has 12 or 13 cards with a value above 5 in his hand. c) What is the expected number of cards in Tim's hand that will be at most 5? d) Tim decides to combine all eighteen decks into one pile and randomize the cards. Tim will randomly select 25 cards from the pile and will calculate a probability related to the number of those cards that are greater than 5? Is there a valid approximation that can be used to answer this question? If so, state the distribution, parameter(s) and support, along with the reason that the approximation is valid. If not, explain why not. e) If you stated that there is a valid approximation in part d) use this to find the probability that exactly 20 of the 25 selected cards have a value greater than 5. If not, use the exact distribution to compute this probability.

HURRY HELP PLS‼️‼️‼️
Brums [2.3K]

Answer:

Step-by-step explanation:

To solve this problem you need the function

 

h(t) = -16t2 + v0t + h0

where t = time

v0 is the initial velocity, which in our case is 0

h0 = initial height, which in our case is 256

h(t) = 0 since we want to know when the ball will hit the ground.

 

0 = -16 t2 + 256

 

And we can solve for t

 

If we rearrange the terms we see that this is a difference of 2 squares

0 = 256 - 16t2

 

0 = (16-4t)(16+4t)

Setting each factor = 0

16-4t=0       16+4t=4

t = 4             t = -4

 

The second solution is discarded as time cannot be negative.

 

So the ball will hit the ground in 4 seconds.

Manufacturers are testing a die to make sure that it is fair (has a uniform distribution). They roll the die 66 times and record
steposvetlana [31]

Answer:

We should reject H0

At the 5% significance level, there is sufficient evidence to conclude that the die is not fair.

Step-by-step explanation:

Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The critical value is 15.091 and  test statistic is 11.070. The null hypothesis is rejected or accepted on the basis of level of significance. When the p-value Test statistics is greater than level of significance we fail to reject the null hypothesis and null hypothesis is then accepted. In the given case p-value is less than critical value then we should reject the null hypothesis.
