PLEASE HELP!!!!!!Which of the following experiments could be used to simulate an event in which the probability of success, P(success), is 0.65 and the number of successes out of 20 events is desired?

A, Use a spinner that is divided into five equal parts. Choose three colors for successful; the other two colors represent unsuccessful. Spin the spinner 20 times, once for each event.

B. Use a random number table consisting of the digits 0 through 9, with digits 0 through 3 representing successful and the remaining digits, 4 through 9, representing unsuccessful. Choose 20 digits, one for each event.

C. Roll a 10-sided die. Let 1 through 5 represent successful and the values 6 through 10 indicate unsuccessful. Roll the die 20 times, once for each event.

D. Count out 65 yellow beads and 35 pink beads. Select 20 of these beads at random. Let a yellow bead represent successful and a pink bead represent unsuccessful.

Answer: the following experiments could be used to simulate an event in which the probability of success, P(success), is 0.65 and the number of successes out of 20 events is:

D. Count out 65 yellow beads and 35 pink beads. Select 20 of these beads at random. Let a yellow bead represent successful and a pink bead represent unsuccessful.

65 + 35 = 100
65/100 = 0.65

Simplify and solve this equation: 4m + 9 + 5m – 12 = 42.A. m = -4
B. m = 4
C. m = –5
D. m = 5

Answers

4m + 9 + 5m – 12 = 42
Given the equation combine all similar terms found on a side of the equation.
You can add the "m" and get: 9m + 9 – 12 = 42
You can combine the 9 and the -12 and get: 9m - 3 = 42
Toget the "m" alone add or subtract any number necessary from the leftside so the number is 0, and do the same to the right: 9m - 3 + 3 = 42 +3, leaving you: 9m = 45
Divide each side by the number of "m" you have: (9m)/9 = 45/9 which simplifies to m=5.

The solution of expression 4m + 9 + 5m - 12 = 42 by combining like terms is,

⇒ m = 5

Given that,

A mathematical expression is,

⇒ 4m + 9 + 5m - 12 = 42

Now, simplify the expression by combining like terms and solve for m as,

⇒ 4m + 9 + 5m - 12 = 42

Combine like terms,

⇒ 9m - 3 = 42

Add 3 on both sides,

⇒ 9m = 42 + 3

⇒ 9m = 45

Divide by 9 on both sides,

⇒ m = 45/9

⇒ m = 5

So, the solution is,

⇒ m = 5
