Um, I am sorry but this question is unanswerable. The reason for that matter is the desired answer is not specified in the question. (If the answer you seek is "Are they equal?" than the answer is no because the answers equal 884.99 and 4.16 so the answers do not equal. Hope that answer helped.)

In how many ways can a photographer at a wedding arrange six people in a row, including the bride and groom, if a) the bride mus

ELEN [110]

Answer: a) 240, b) 480, c) 360

Step-by-step explanation:

Since we have given that

Number of people = 6

Number of bride and groom = 2

So, remaining people = 6-2 = 4

So, using the fundamental theorem of counting

remaining people can be arranged in

$4!=4\times 3\times 2\times 1=24$

Since bride has 5 positions to stand and grooms too has 5 positions to stand.

so, Number of positions for both bride and groom = 5+5=10

So, a) the bride must be next to the groom?

Number of ways = $24\times 10=240$

b) the bride is not next to the groom?

Total number of ways would be

$6!=6\times 5\times 4\times 3\times 2=720$

So, Number of ways that the bride is not next to the groom is

$720-240=480$

c) the bride is positioned somewhere to the left of the groom?

If Groom is in second position, bride has 1 ways to stand

If Groom is in third position , bride has 2 ways to stand

If Groom is in fourth position, bride has 3 ways to stand

If Groom is in fifth position, bride has 4 ways to stand

If Groom is in sixth position, bride has 5 ways to stand.

So, Number of ways to stand = 1+2+3+4+5=15

So, the total number of ways bride is positioned somewhere to the left of the groom is given by

$24\times 15=360$

Hence, a) 240, b) 480, c) 360

Koos spent 3/7 of his monthly pocket money during the first week. The following week he spends two- thirds of what he had spent

Elena-2011 [213]

Answer: 2/7

Step-by-step explanation:

The total amount of pocket money he has is 7/7.

He spent 3/7 of his pocket money during the first week.

He then spends 2/3 of what he spent the previous week, 2/3 * 3/7 which is 2/7.

What he has left is 7/7 - 3/7 - 2/7 = 2/7.

In a prior sample of U.S. adults, the Center for Disease Control (CDC), found that 8% of the people in this sample had pinworm b

kow [346]

Answer: a) 453 b) 1537

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.025

Critical value for 95% confidence interval : $z_{\alpha/2}=1.96$

a) The prior estimate of population proportion : p=0.08

Required sample size :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.08(1-0.08)(\dfrac{1.96}{0.025})^2\\\\=452.386816\approx453$

The minimum sample size is 453 U.S. adults.

b) Since the prior estimate of population proportion is not available , so we take p= 0.5

Required sample size :-

$n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.025})^2\\\\=1536.64\approx1537$

The minimum sample size is 1537 U.S. adults.
