A square of side 72 cm and a rectangle of length 90 cm have same perimeter. Find the difference in areas ?
olga_2 [115]

Answer:

324 cm²

Step-by-step explanation:

→ Work out perimeter of square

72 + 72 + 72 + 72 = 288

→ Work out the width of the rectangle

288 - (90 × 2) = 108

108 ÷ 2 = 54

→ Work out area of square

72 × 72 = 5184 cm²

→ Work out area of rectangle

90 × 54 = 4860 cm²

→ Minus the areas from each other

5184 cm² - 4860 cm² = 324 cm²

In engineering and product design, it is important to consider the weights of people so that airplanes or elevators aren't overl
Nataly [62]

Answer:

0.002

Step-by-step explanation:

We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.

Standard error of the mean = standard deviation/√n

Standard error of the mean = 32/√50 = 4.52

Now we can use this Standard error of the mean to estimate z as follows:

Z = (x – mean)/standard deviation

Z = (190-177)/4.52

Z = 2.87

Using  a Z table we can find probability that mean is under 190

P (z<190)= 0.998

For the probability that the mean exceed 190 lbs we substract from 1

P(z>190) = 1 - 0.998 = 0.002
