The Hiking Club plans to go camping in a State park where the probability of rain on any given day is 2/3. What is the probabili
Aleksandr [31]

Answer:

19.75%

Step-by-step explanation:

Since we are trying to find the probability for a sequence of events then we need to multiply the probability of each event happening separately from each other. Since the probability of it raining on a single day is 2/3 we need to multiply this value with itself 4 times (one for each day).

2/3 * 2/3 * 2/3 * 2/3 = 16/81 or 0.1975 or 19.75%

Therefore the probability would be 16/81 or 0.1975 or 19.75%

Step-by-step explanation:

2x - 6 = 5y - 3

2x - 6 + 3 = 5y

2x - 3 = 5y

y = ( 2x - 3 ) / 5

if 10 is less than a number is multiplied by 3, the result is equal to 2 times the number. What is the number?
olya-2409 [2.1K]
Hello!

We know that

(x - 10) * 3 = 2x

Distribute the 3

3x - 30 = 2x

Subtract 2x from both sides

x - 30 = 0

Add 30 to both sides

x = 30

The answer is 30

Hope this helps!
