Answer: 3 x 7


Explanation:
So the question is asking you to multiply two prime numbers in order to get 21.
Since 3 and 7 are both prime numbers, you can express 21 as 3 x 7

Hope this helps! :)

Here is a list of prime numbers if it helps you. (prime numbers are in blue):

Problem 1

Answer: Closer to 1

Explanation:

There are 20 gumballs total. Half of this is 20/2 = 10 gumballs. If there's more than 10 of one color, then the probability of getting that color is closer to 1, than it is to 0. Here we have 12 pink which is greater than 10, so that's why the answer is closer to 1.

================================================

Problem 2

Answer: Closer to 0

Explanation:

The amount of green (3) is less than 10, so that's why the probability is closer to 0 than it is to 1. We can see that 3/20 = 0.15 is less than 0.50

================================================

Problem 3

Answer: Closer to 0

Explanation:

We have a similar situation compared to problem 2. This time we have 5/20 = 0.25 which is less than 0.50

================================================

Problem 4

Answer: 48% chance; fairly likely

Explanation:

We have 12 green out of 25 total, so the probability of choosing green is 12/25 = 0.48 = 48%. While this probability is not over 50%, I still say it's fairly likely considering the other colors lead to smaller probabilities. For instance, purple has a chance of 6/25 = 0.24 = 24% and orange has a probability of 2/25 = 0.04 = 4%, both of which are smaller than 48%

I cannot figure this problem out
sveta [45]

Answer:

31 customers

Step-by-step explanation:

First, find the percentage of customers who wore a large. This is 26/(26 + 52), or 1/3 of the customers. Take 1/3 of the new customers, and 1/3 of 93 is 31. 31 customers will wear a size large.

Hopefully this helps! Let me know if you have any questions

At a raffle, 1500 tickets are sold for $2 each for four prizes of $500, $250, $150, and $75. You buy one ticket. What is the exp
Kisachek [45]
To find the expected value of your gain in each prize, subtract the price of the ticket from the prize:

If the prize is $500: $500 - $2 = $498
If the prize is $250:  $250 - $2 = 248
If the prize is $160: $160 - $2 = $73

But if you did not win any cash prize, you do not have any gain because
0 cash prize - $2 ticket = -$2 which is a loss

Solve the equation.<br><br> 3x-5=2(-x-5)
Ira Lisetskai [31]

Answer:

The value of x = -1

Step-by-step explanation:

=> 3x-5=2(-x-5)

=> 3x - 5 = -2x - 10

=> 3x + 2x = -10 +5

=> 5x = -5

=> x = -5/5

=> x = -1
