The table have the following results:

 

Hearts – 7

Diamonds – 4

Clubs – 8

Spades – 5

There is a total of 24

 

The question is asking for the probability of not selecting a heart.

So we need to add the probabilities of the diamonds, clubs, and spades since these suits are different from hearts.

So = 4 + 8 + 5 = 17

And we have a total of 24 cards

<span>Therefore the probability is 17/24. </span>

Allegra has a cell-phone plan that charges $65 per month and $0.10 for every minute that she uses the phone beyond what her plan
Bond [772]
It seems confusing, but it's just breaking down the steps for you. It's done the same as any other word problem.
a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
   The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
     8.40 = 0.10m
       84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.

If a translation maps point (3, 2) to (5,3); or T:(3, 2) - (5,3), indicate the image for (2,4)
Zinaida [17]

Answer:

A

Step-by-step explanation:

Note that for (3, 2) → (5, 3)

The x- coordinate of the image is 2 more (+ 2) than the original and the y- coordinate of the image is 1 more (+ 1) than the original, that is

(x, y ) → (x + 2, y + 1 ) ← rule to obtain image, hence

(2, 4 ) → (2 + 2, 4 + 1 ) → (4, 5 ) → A

Consider Z1= 4-4 radical 3i and Z2= -16 i. What is Z1-Z2?
goldfiish [28.3K]

Answer:

Option (3)

Step-by-step explanation:

Z_1=4-4\sqrt{3}i

Z_2=-16i

Z_1-Z_2=(4-4\sqrt{3}i)-(-16i)

            =4-4\sqrt{3}i+16i

            =4-(4\sqrt{3}i-16i)

            =4-4(\sqrt{3}-4)i

Therefore, Option (3) will be the correct option.
