Answer:
they usually cost nothing if you go through your bank
#5: cost: y
Number of beads: x
y=0.48*x
So for 4 beads: 1.92
for 5 beads: 2.4
#6: the x th term in the sequence is y
y=17-2x
The 10th term is -3
Answer:
20
85%
Step-by-step explanation:
You are given the function 
If n is the number of hours, then initially n=0 and

If S(n) is the function of exponential growth, then it can be represented as

where I is the initial amount, r -is the percent growth rate and n is the number of hours.
If b = 1.85, we can represent it as b = 1 + 0.85. Thus, the hourly percent growth rate of the bacteria would be 0.85=85%.
Answer:

Step-by-step explanation:
So what is the average rate of change? Basically, it's the slope. In fact it's exactly the slope for a linear equation, but how do you find slope?

Sp we just plug the values in.


Answer:
1/6 ( under not enough of other criteria)
Step-by-step explanation:
total of student: 60
1/3 male: 60 x 1/3 = 20
Female = 60 - 20 = 40
1/2 with brown hair: 60 x 1/2 = 30
It seems the answer of 20/60 x 30/60 = 1/3 x 1/2 = 1/6 is the result, but consider the brown hair number is larger than male student (30 vs 20). Therefore there can have the chance of all the boys are brown hair and be chosen, then the probability will become 20/60 = 1/3. While probability result is not a certain result, it only to predict how likely things are to happen.
Therefore I think 1/6 is an answer.
