The daily revenue at a university snack bar has been recorded for the past five years. Records indicate that the mean daily reve
faltersainse [42]

Answer: 0.9938

Step-by-step explanation:

Let x be the random variable that represents the daily revenue at a university snack bar.

As per given , we have

\mu=2700 , \sigma=400 and n= 100

Using formula z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}} ,

z-score for x= 2600

z=\dfrac{2600-2700}{\dfrac{400}{\sqrt{100}}}=-2.5

The probability that the average daily revenue of the sample is higher than $2600 :

P(x>2600)=P(z>-2.5)=P(z   [P(Z>-z)=P(Z<z)]

=0.9937903\approx0.9938

Therefore, the probability that the average daily revenue of the sample is higher than $2600 = 0.9938

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the gr
Anon25 [30]

Answer:

Step-by-step explanation:

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

\frac{l}{b}= \frac{1}{2}

b = 2l ------(2)

From equations (1) and (2),

l + 2l = 75

3l = 75

l = 25 m

Width 'b' = 2(25) = 50 m

Now we have to draw a rectangle with a scale = 25 : 2

Therefore, Scale factor = \frac{25}{l}=\frac{25}{2}

l = 2 cm

Similarly,

\frac{50}{w}=\frac{25}{2}

w = 4 cm

Now we can draw a rectangle with length = 2 cm and width = 4 cm.
