How many tissues should the kimberly clark corporation package of kleenex contain? researchers determined that 60 tissues is the

Agata [3.3K]

Answer:

Step-by-step explanation:

For the null hypothesis,

µ = 60

For the alternative hypothesis,

h1: µ < 60

This is a left tailed test

Since the population standard deviation is not given, the distribution is a student's t.

Since n = 100,

Degrees of freedom, df = n - 1 = 100 - 1 = 99

t = (x - µ)/(s/√n)

Where

x = sample mean = 52

µ = population mean = 60

s = samples standard deviation = 22

t = (52 - 60)/(22/√100) = - 3.64

We would determine the p value using the t test calculator. It becomes

p = 0.00023

We would reject the null hypothesis if α = 0.05 > 0.00023

The function. In the graph is f(x) =

Tanya [424]

Answer:

$x^3-2x^2-5x+6$

Step-by-step explanation:

We have been given a graph of the function f(x).

Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:

$x^4-2x^2+5x+6$

$x^3-2x^2-5x+6$

$x^3-2x^2+5x+6$

$-x^4-2x^2+5x+6$

We see that graph has end points in opposite direction then the degree of polynomial must be ODD.

Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.

Only $x^3-2x^2-5x+6$ satisfies the given points from graph.

Hence correct choice is $x^3-2x^2-5x+6$ .

The area of a rectangle is 5/6 sq foot. The width is 2/3 foot. The length of the rectangle is how many feet

max2010maxim [7]

Answer:

The answer is

$\frac{5}{4} \\$

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length

<h3> $length = \frac{area}{width} \\$ </h3>

From the question

area = 5/6 sq. feet

width = 2/3 foot

Substitute the values into the above formula and solve for the length

The length is

$length = \frac{5}{6} \div \frac{2}{3} \\ = \frac{5}{6} \times \frac{3}{2} \\ = \frac{5}{2} \times \frac{1}{2} \\ = \frac{5}{4}$

We have the final answer as

$\frac{5}{4} \\$

Hope this helps you

The population of Peru is 10904 the population of Franklin is 25248. The population of Franklin is percent more than the populat

LekaFEV [45]

Answer:

132%

Step-by-step explanation:

The population of Peru = 10904

The population of Franklin = 25248.

Difference = 25248-10904=14,344

Expressing as a percentage of the population of Peru

$\dfrac{14344}{10904} X 100$

=132%

Therefore, the population of Franklin is 132% more than the population of Peru.
