Area filled by nature books = 1/6 of 9 feet = 1/6 x 9 = 3/2 feet.

Number of nature books = 3/2 / 3/5 = 2.5 ≈ 3 books.

Select the correct car trips. Listed are the distances traveled by four cars and the time it took each car to cover that distanc

seropon [69]

Answer:

Speeds of car 1 and car 4 are same.

Step-by-step explanation:

Speed of an object = $\frac{\text{Distance traveled}}{\text{Time}}$

For car 1,

Speed of car 1 = $\frac{350}{5}$

= 70 miles per hour

For car 2,

Speed of car 2 = $\frac{240}{4}$

= 60 miles per hour

For car 3,

Speed of car 3 = $\frac{320}{5}$

= 64 miles per hour

For car 4,

Speed of car 4 = $\frac{420}{6}$

= 70 miles per hour

Therefore, speeds of car 1 and car 4 are same.

a carnival game consists of 3 dart throws at a target. The probability of scoring a hit on any one throw is 30%. Using the binom

Ghella [55]

Answer: Probability of scoring 2 hits = 0.63.

Step-by-step explanation:

Since we have given that

Number of dart throws at a target = 3

Probability of scoring a hit on any one throw = 30%

We will use "Binomial Distribution" i.e.

$P=^nC_rp^r(1-p)^{n-r}$

where,

n denotes number of dart throws at a target,

r denotes number of required throws

p denotes probability of success

(1-p) denotes probability of failure

So, Probability of success is given by

$\frac{30}{100}=\frac{3}{10}$

Probability of failure is given by

$1-\frac{30}{100}=\frac{70}{100}=\frac{7}{10}$

We will use "Binomial Distribution" i.e.

$P(X=2)=^3C_2(\frac{3}{10})^2\times (\frac{7}{10})\\\\P(X=2)=\frac{9}{100}\times \frac{7}{100}\\\\P(X=2)=\frac{63}{100}\\\\P(X=2)=0.63$

Hence, Probability of scoring 2 hits = 0.63.
