Answer:

(4)^{20}

Step-by-step explanation:

Total number of questions = 20

Possible options for each question = 4

Sample space contains the total number of possible outcomes.

For every question there are 4 possible ways to select an answer. This holds true for all 20 questions. Selecting an answer for a question is independent of other questions/answers,

According to the counting principle, the total number of possible outcomes will be the product of the number of possible outcomes of individual events. Possible outcomes for each of the 20 questions is 4. This means we have to multiply 4 twenty times to find the total number of possible outcomes.

So, the number of elements in the sample space would be:

(4)^{20}

Find the value of Z. Explain step by step and I'll mark you brainliest.<br><br>2.5(2z+5)=5(z+2.5)​
Yuliya22 [10]
The answer is infinite (0=0).

1. Use distributive property to multiply the parentheses. You’ll end up with 5z+12.5=5z+12.5.
2. You’ll notice the equation equals each other. 5z-5z equals zero, same for 12.5.

I need Helppppppppppppppp with this
amid [387]

Answer:

Option A

Step-by-step explanation:

Jessica divides the ribbon in three parts out of which length of one part = 3\frac{1}{2} inches

Let the length of other two parts = x inches

Total length of whole ribbon = 12 inches

3\frac{1}{2}+x+x=12

3\frac{1}{2}+2x=12

2x=12-3\frac{1}{2}

2x=12-\frac{7}{2}

2x=\frac{24-7}{2}

2x=\frac{17}{2}

x=\frac{17}{4}

x=7\frac{1}{4} inches

Therefore, option A will be the answer.
