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
,
and n= 100
Using formula ,
z-score for x= 2600
The probability that the average daily revenue of the sample is higher than $2600 :
[P(Z>-z)=P(Z<z)]
Therefore, the probability that the average daily revenue of the sample is higher than $2600 = 0.9938
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
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 =
l = 2 cm
Similarly,
w = 4 cm
Now we can draw a rectangle with length = 2 cm and width = 4 cm.
