PLEASE HELP ME TO SOLVE ALL OF THE ABOVE QUESTION I DON'T HAVE MUCH TIME URGENT!!! thank you

6 points Save 9 people will be lined up to have their picture taken. If 4 of these people insist on standing next to each other, in how many different ways can these 9 people be ordered? Do not use comma or decimal in your answer. For example if your answer is 5000, just enter 5000, do not enter 5,000 or 5.000. Question 3 of 9 Question 3 7 points Save Answer Find the probability that the continuous random variable X will take a value between 0.1 and 0.8, if its probability density function is CX f(x) = -Le if Osxsi, elsewhere. (Of course, first you need to find the value of c.) Caution: You have to write your answer as a decimal number rounded to at least two digits after the decimal point. For example, if your answer is 0.34495623, you can enter 0.34. Do NOT use a comma, 0,34 is not acceptable. estion 2 >> Calculate the Sample Variance for the following data set: 8 points Save Answer 2, 0, 4, 8. CAUTION: When you enter a decimal number, you should use a decimal point, not a comma. For example, if your answer is 3.4749, then you can round it to 3.47. But you should not use a comma: 3,47 will be unacceptable. Question 4 of 9 > >> Question 4 7 points Save Answer Let f(x) be the probability distribution of the discrete random variable X. And let F(x) be the cumulative distribution for X. Find F(1.32), given that f(x)=C(x2+1), where xE{0,1,2,3} (Of course, first you need to find the value of c.) Caution: You have to write your answer as a decimal number rounded to at least two digits after the decimal point. For example, if your answer is 0.34495623, you can enter 0.34. Do NOT use a comma, 0,34 is not acceptable. Question 7 8 points Save Answer Find P(X >> Calculate the Sample Variance for the following data set: 8 points Save Answer 2, 0, 4, 8. CAUTION: When you enter a decimal number, you should use a decimal point, not a comma. For example, if your answer is 3.4749, then you can round it to 3.47. But you should not use a comma: 3,47 will be unacceptable. Question 4 of 9 > >> Question 4 7 points Save Answer Let f(x) be the probability distribution of the discrete random variable X.
