Answer:

B. -0.9, 8.9

Step-by-step explanation:

The value(s) of the variable can be found by undoing the operations done to it.

Undo the square by taking the square root:

x -4 = ±√24 = ±2√6

Undo the subtraction by adding 4:

x = 4 ±2√6 ≈ {-0.8990, 8.8990} . . . keep enough digits to round correctly

The approximate solutions are ...

-0.9, 8.9

Jessica records the number of winners at the Dunk-a-Teacher booth at the town fair as shown in the table. If there are 750 conte

Keith_Richards [23]

Between 75 and 98.

Step-by-step explanation:

Let's first have a look at the previous data available:

Friday, 27 dunk teachers out of 215 participants (12.5%)

Saturday: 54 dunk teachers out of 417 participants (12.9%)

Sunday: 39 dunk teachers out of 368 participants (10.6%)

So, based on the previous 3 days, she can expect between 10% and 13% will dunk a teacher.

If she has 750 contestants on Monday, the number of winners should then be in the range of 75 (10% of 750) and 98 (13% of 750).
