Q13. two cards are selected at random from a normal playing pack with replacement. this
experiment is repeated 2704 times with the cards being replaced each time.
a what is the expected number of times the result would be two spades?
b what is the expected number of times the result would be two aces?
c what is the expected number of times the result would be two picture cards?
d what is the expected number of times the result would be two cards with a number
less than 9?
q14. two dice are tossed one after the other onto a table. this event is repeated 144 times.
a on how many occasions would you expect the result to be a 6 then a 1?
b on how many occasions would you expect the result to be two 3s?
c on how many occasions would you expect the result to be two odd numbers?

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

idk

step-by-step explanation:

payback

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
