An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 334 people living in East Vancouver and finds that 43 have recently had the flu. Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to have a margin of error no larger than 0.03. How large a sample should she take to achieve this?

F(x) = -7x - 1
f() = -8

Answers

Answer:

  f(1) = -8

Step-by-step explanation:

Apparently, you want the argument of the function such that the function value is -8. Fill in the given information and solve for x:

  -8 = -7x -1

  -7 = -7x . . . . add 1

  1 = x . . . . . . . divide by -7

Now, you know that ...

  f(1) = -8

Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5?y = x - 1/5
y = x + 1/5
y = 1/5x
y = 5x

Answers

Answer:

y = 1/5x

Step-by-step explanation:

quickly enter 0 1 2 3 4 5 for x

see what you get for y

for y = 1/5x you get the SAME number whenever you do y divided by x

The equation that represents a proportional relationship with a constant of proportionality equal to 1/5 is:

y = 1/5x

A proportional relationship between two variables x and y can be written as:

y = kx

Where k is the constant of proportionality.

If k = 1/5, then the equation becomes:

y = (1/5)x

Which is the same as:

y = 1/5x

So out of the given options, y = 1/5x is the only equation that represents a proportional relationship with a constant of proportionality equal to 1/5.

The other equations have different constants of proportionality:

- y = x - 1/5 -> k = 1

- y = x + 1/5 -> k = 1

- y = 5x -> k = 5

Therefore, y = 1/5x is the correct equation with a constant of proportionality equal to 1/5.

Mikkel pays a 4 percent state income tax on his earnings. If he earns $1,867, how much state income tax can he expect to pay? $46.68 $74.68 $466.75 $746.80

Answers

Answer:

$74.68

Step-by-step explanation:

Convert the percent to a decimal.

4% = 0.04

Multiply his income by the percentage to find the tax.

$1,867 × 0.04 = $74.68

He can expect to pay $74.68.

b. 5P5 × 20P15
c. 5C5 × 25C14
d. 5P5 × 15P15
e. 5P5 × 25C15

Answers

Answer:

The correct option is b.

Step-by-step explanation:

It is given that the school bus has 25 seats, with 5 rows of 5 seats.

The number of students from the first grade is 15 and the number students from the second grade is 5.

The formula to arrange r items in n places is

^nP_r=(n!)/((n-r)!)

The number of seats in first row is 5 and the number students from the second grade is 5. So, the total number of arrangement is

^5P_5

The number of seats except first row is 20 and the number students from the first grade is 15. So, the total number of arrangement is

^(20)P_(15)

The total number of ways the students can be seated if all of the second-grade students occupy the first row is

^5P_5* ^(20)P_(15)

Therefore the correct option is b.

b
