Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective

Answer: The maximum numbers of rose bushes in garden is 16.
Explanation:
It is given that for every 18 mums she plants 12 tulips and for every 9 tulips there are 2 rose bushes.
Let the mums, tulips and roses are defined by M, T and R respectively.
From the given information,




Since it is given that
, we get,





From the above equation 110 mums we need 16.3 roses. So, the number mums exceeds 110 if the roses are 17.
Therefore, the maximum numbers of rose bushes in garden is 16 for which the number of mums cannot exceed 110.
