In a batch of 500 calculators, 25 were found to be defective. What is the probability that a calculator chosen at random will be

baherus [9]

Answer: 5%

Step-by-step explanation:

Probability for any event = $\dfrac{\text{Number of favorable outcomes}}{\text{total outcomes}}$

Given: Number of defective calculators = 25

Total calculators = 500

The probability that a calculator chosen at random will be defective= $\dfrac{25}{500}$

$=0.05$

$=0.05\times100\%\\\\= 5\%$

Hence, the required probability = 5%

A rhombus has diagonals measuring 12 units and 16 units. What is the perimeter of the rhombus?

Misha Larkins [42]

4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 12^2 + 16^2
4 * side^2 = 144 + 256
4 * side^2 = 400
side^2 = 100
side = 10
So the perimeter = 4*10 = 40

280 eels

92 + 56 + 52 = 200
eel = 56/200

56 *5     x
----- =   --------
200   *5 1000
56(5) = 280 x = 280

56/200 = 7/25
7/25 = 280/1000
