Question

Out of 60 pictures of tiger cubs and kittens, of which 45 were kitten, how many tiger cubs must be model identify correctly along with 35 kitten images correctly identified so that the accuracy is more than75%?

Answer 1

To determine the number of tiger cubs that must be correctly identified, we need to set up an equation that represents the condition that the accuracy must be more than 75%. The accuracy is calculated as the number of correctly identified images divided by the total number of images.

In this case, the total number of images is 60, and the number of correctly identified images is 35 kittens plus the number of correctly identified tiger cubs. We can represent this as the equation:

(35 + tiger cubs) / 60 > 0.75

To solve for the number of tiger cubs, we can multiply both sides of the equation by 60 and simplify:

35 + tiger cubs > 45

Subtracting 35 from both sides gives us:

tiger cubs > 10

So, to achieve an accuracy of more than 75%, the model must correctly identify at least 11 tiger cubs.
