20baskets into 4minutes
Crank
Put this into ratio form:

20 baskets/ 4 minutes.

This means for every 4 minutes, you can make 20 baskets.

Now solve for 1 minute...how many baskets can you make in one minute.

You can solve this in many ways:

1. Cross Multiply:

20/4 = x/1...20×1= 20 ÷ 4= 5 baskets per minute

2. Simplify- (simpler way to solve)

20 baskets ÷ 4 minutes= 5 baskets in 1 minute 

3. Critical Thinking:

how many times can 4 go into 20? 5 times. So there are:

A small combination lock on a suitcase has 55 ​wheels, each labeled with the 10 digits 0 to 9. How many 55 digit combinations ar
den301095 [7]
Suppose a_n is the number of possible combinations for a suitcase with a lock consisting of n wheels. If you added one more wheel onto the lock, there would only be 9 allowed possible digits you can use for the new wheel. This means the number of possible combinations for n+1 wheels, or a_{n+1} is given recursively by the formula

a_{n+1}=9a_n

starting with a_1=10 (because you can start the combination with any one of the ten available digits 0 through 9).

For example, if the combination for a 3-wheel lock is 282, then a 4-wheel lock can be any one of 2820, 2821, 2823, ..., 2829 (nine possibilities depending on the second-to-last digit).

By substitution, you have

a_{n+1}=9a_n=9^2a_{n-1}=9^3a_{n-2}=\cdots=9^na_1=10\times9^n

This means a lock with 55 wheels will have

a_{55}=10\times9^{54}

possible combinations (a number with 53 digits).

A die is loaded so that the number 6 comes up three times as often as any other number. what is the probability of rolling a 1 o
Mila [183]

Answer:

1/2.

Step-by-step explanation:

Probability totals must add up to 1.

P = probability.

If P(any number other than 6) = x,  then P(6) = 3x, so

3x + 5x = 1

x = 1/8

P(6) = 3/8 and P(not 6) = 1/8

Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).
