gregori [183]

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

Mrs. Kozlova has a wonderful flower garden. She made sure that for every 18 mums she plants 12 tulips and for every 9 tulips the
Ivanshal [37]

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,

9T=2R

1T=\frac{2}{9}R

12T=\frac{2}{9}(12)R

12T=\frac{8}{3}R

Since it is given that 18M=12T, we get,

18M=\frac{8}{3}R

1M=\frac{8}{3(18)}R

1M=\frac{4}{27}R

110M=\frac{4}{27}(110)R

110M=16.296R

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.
