Answer:
$780
Step-by-step explanation:
600*.30=180
600+180=780
Answer:
SEE BELOW
Step-by-step explanation:
A: Yes, it is 18.80%. Sample Mean= 135, Sample Standard deviation= 25/sq rt of 10 = 7.906, normalcdf(142, 999999, 135, 7.906) = .18796 × 100 = 18.796 = 18.80%
B: If we increase the sample size to 50, then, due to the Central Limit Therme, there should be less variation within the data (it should point to a more clear center). Sample Mean= 135, Sample Standard deviation= 25/sq rt of 50 = 3.535, normalcdf(142, 999999, 135, 3.535) = .02385 × 100 = 2.385 = 2.39%
Answer:
304 and 512
Step-by-step explanation:
The difference between the perimeters of the two rectangles will be 4x + 3
The formula for the perimeter of rectangle is given as :
P = 2(L + B)
Where P = perimeter of the rectangle
L = length of the rectangle
B = breadth of the rectangle
Now we have given two rectangle on is smaller than the other.
To find the difference between the perimeter of the two rectangles. We will first calculate the perimeter of both the rectangle.
Perimeter of the bigger rectangle = 2( 5x + 3 + 2x)
= 2(7x + 3)
= 14x + 3
Perimeter of the smaller rectangle = 2(2x + 3x)
= 2*5x
=10x
Difference between the two perimeters = (Perimeter of the bigger rectangle) – (Perimeter of the smaller rectangle)
= (14x + 3) – 10x
= 4x + 3
Thus the difference between the perimeters of the two rectangle will be 4x + 3
