You need a mean of at least 90 points to advance to the next round of the touch-screen trivia. What score in the fifth game will
lianna [129]

Answer:

At least 98 is needed in the 5th game

Step-by-step explanation:

The missing parameters are:

Game\ 1 = 95

Game\ 2 = 91

Game\ 3 = 77

Game\ 4 =89

Mean = 90 at least

Required

The score in game 5 to make you advance

Mean is calculated as:

Mean = \frac{\sum x}{n}

So, we have:

Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}

Mean = \frac{352 + Game\ 5}{5}

The mean must be at least 90.

So, we have:

\frac{352 + Game\ 5}{5} \ge 90

Multiply both sides by 5

5 * \frac{352 + Game\ 5}{5} \ge 90 * 5

352 + Game\ 5 \ge 450

Make Game 5 the subject

Game\ 5 \ge450 - 352

Game\ 5 \ge 98

<em>At least 98 is needed in the 5th game</em>

Step-by-step explanation:

x+y=64

x=16+3y

Now, substitute the second equation into the first one.

16+3y+y=64

16+4y=64

4y=48

y=12

Substitute 12 into one of the equations in order to find x.

x=16+3(12)
