Hi can someone please help me?

Both can be right because if the function goes up, turns and goes down, between x = -2 and x = 2, it can happen that f(-2) = f(2) and then the average rate of change is [f(2) - f(-2)] / [2-(-2)] which is 0/4 = 0.

If Susie is late for school one particular day of the week, the probability she arrives on time the next day is 0.8. If she arri

Andre45 [30]

Answer:

0.273 = 27.3% probability that she was late on Thursday.

Step-by-step explanation:

On time on Monday, late on Thursday:

Possible outcomes (tuesday-wednesday-thursday).

on time(0.7 probability) - on time(0.7 probability) - late(0.3 probability)

on time(0.7 probability) - late(0.3 probability) - late(0.2 probability)

late(0.3 probability) - on time(0.8 probability) - late(0.3 probability)

late(0.3 probability) - late(0.2 probability) - late(0.2 probability).

What is the probability she was late on Thursday?

Sum of these four outcomes. So

$p = 0.7*0.7*0.3 + 0.7*0.3*0.2 + 0.3*0.8*0.3+0.3*0.2*0.2 = 0.273$

0.273 = 27.3% probability that she was late on Thursday.

What is the value of the function f(x) = 1.5x + 7.6 when x = 1.1?

Triss [41]

So the equation is 1.5(1.1) +7.6

1. Multiply 1.5* 1.1 = 1.65

2. Add 1.65 +7.6= 9.25

I would have to say the answer is 9.25
