1÷2 would equal a half or 0.5.And the 0.5 is negative on the answer keys so -1/2 and -(1/2) are correct. So student one and student three are correct.

babymother [125]

Answer:

See below in bold.

Step-by-step explanation:

1.   The sequence is 1000, 2000, 4000, 8000.

2.  The common ratio  is 2000/1000 = 2.

3.   Number of bacteria after 7 hours is 1000(2)^(7- 1)

    = 64,000.

4.   1000(2)^(x-1)  > 1,000,000

2^x-1  > 1000

x- 1  log 2 > log 10

x- 1 > 9.96

x > 10.96

During the 11th hour.

The probability that a household owns a pet is 0. 55. Suppose there are 5 houses on a block. Assuming each household is independ
Alexandra [31]

If the probability that a household owns a pet is 0.55 then the probability that all households will have pets is equal to 0.0503.

Given that the probability that a household owns a pet is 0.55 and there are 5 houses on a block.

We are required to calculate the probability that all the five households will have pets.

Probability is basicallly the chance of happening an event among all the events possible. It cannot be negative.

Binomial probability distribution is basically the probability calculations but in different combinations.

In this we have to calculate the probability that all the houses will have the pets then the probability that all five households will have pets is equal to 5C_{5}(0.55)^{5} (1-0.55)^{0}

=1(0.0503)(0.45)^{0}

=1*0.0503*1

=0.0503

Hence the probability that all the five households will have pets is equal to 0.0503.

klio [65]
3 + 8 + 10 + 12 + 15 = 48

48 / 5 = 9.6 or 10

3 - 7
8 - 2
10 - 0
12 - 2
15 - 5

7 + 2 + 0 + 2 + 5 = 16

16 / 5 = 3.2 or 3

The Mean Absolute Deviation is approximately 3
