In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria population of b cells. She discovers

that after 3 hours, the population of bacteria is
b2 cells. Three hours later, the bacteria population is b3 cells. If the population of the bacteria after these 6 hours is one thousand cells, what was the population at the start? Explain how you found your answer.

Answer:

Initial population: b=10

Step-by-step explanation:

Initil population: b

After 3 hours: b²

After 6 hours: b³

It looks like a geometric progression, with ratio b.

Now, after 6 hours: b³=1000=10³

So, initial population is b=10. Note that b is also the growing ratio.

An automobile manufacturer claims that its van has a 44.3 miles/gallon (MPG) rating. An independent testing firm has been contra
natulia [17]

Step-by-step explanation:

H0: u = 44.3

Hi : u# 44.3

Z1-0.05/2

Z1-0.025

Z0.975 = 1.96

Z = x-u/s.d/√n

Z= 44.4 -44.3/2.6/√130

Z = (0.1×11.4018)/2.6

Z=0.44

Since the calcalculated value is less than the table value and does not fall in the rejection region we fail to reject the null hypothesis

8(7 + 23) = 8(7) + 8(?)
34kurt
Answer: 23

When using multiplication with brackets, you multiply the number by all the numbers within the bracket before adding them together.

Therefore when it is 8(7 + 23) it basically means: 8(7) + 8(23)

Write a rule for the nth term of the arithmetic sequence. Then graph the first six terms of the sequence. a6=-12 a12=-36
denis-greek [22]

Answer:

We need to find the first term.  We can use the formula

an = a1 + d(n - 1)

to solve for a1.  We already know the 12th term, a12, common difference, d, and nth sequence, n.

a12 = -36

d = -4

n = 12

-36 = a1 - 4(12 - 1)

-36 = a1 - 44

8 = a1

The first term is 8.  Therefore, your formula is

an = 8 - 4(n - 1)

an = -4n + 12

Then use this formula to graph.

n is the independent variable.

an is the dependent variable.

Your graph will be a line.

n    |       an

___________

1          8

2          4

3          0

4         -4

5         -8

6         -12

Step-by-step explanation:
