Answer: Our required probability is 0.88.

Step-by-step explanation:

Since we have given that

Number of male students are smokers = 10

Number of male students are non smokers = 490

total number of male students = 500

Number of female students are smokers = 40

Number of female students are non smokers = 363

Total number of female students = 403

Probability that both are non smokers is given by

P(Non-smoker\ male)\times P(Non-smoker\ female)\\\\=\dfrac{490}{500}\times \dfrac{363}{403}\\\\=0.98\times 0.9\\\\=0.88

Hence, our required probability is 0.88.

3. Convert 150 yards per minute to feet per day.
vesna_86 [32]

One day has 24 hours.

One hour has 60 minutes.

One day has 24 x 60 = 1440 minutes.

1 yard is 3 feet.

150 yards x 3 = 450 feet.

150 yards per minute = 450 feet per minute.

450 x 1440 = 648,000 feet per day.

Can someone answer this plz (-2z^2-14)-(-12z^2)
Orlov [11]

Answer:

\large\boxed{(-2z^2-14)-(-12z^2)=10z^2-14}

Step-by-step explanation:

(-2z^2-14)-(-12z^2)=-2z^2-14+12z^2\qquad\text{combine like terms}\\\\=(-2z^2+12z^2)-14=10z^2-14
