Liz runs 8 feet per second. Katie runs 350 feet in 31 seconds. Katie runs 350 feet in 31 seconds. Stephanie runs 1 mile in 388 s

VikaD [51]

Answer: Stephanie is the fastest

Step-by-step explanation:

Here we have to find who runs faster:

Liz:

$8 ft/s$

Katie:

$\frac{350 ft}{31 s}=11.29 ft/s$

Stephanie:

$\frac{1 mile}{388 s}. \frac{5280 ft}{1 mile}=\frac{5280 ft}{388 s}=13.60 ft/s$

Noah:

$\frac{541 ft}{1 min}. \frac{1 min}{60 s}=9.01 ft/s$

As we can see after comparing, Stephanie is the fastest, since she travels more distance in less time.

A farmer who grows genetically engineered corn is experiencing trouble with corn borers. A random check of 5,000 ears revealed t

Ivenika [448]

Answer:

Probability that an ear of corn selected at random will contain no borers is 0.4966.

Step-by-step explanation:

We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.

Let X = Number of borers per ear

The probability distribution of the Poisson distribution is given by;

$P(X=x) = \frac{e^{-\lambda }\times \lambda^{x} }{x!} ; x = 0,1,2,3,......$

where, $\lambda$ = parameter of this distribution and in our question it is proportion of bores in the total ears = $\frac{3500}{5000}$ = 0.7

SO, X ~ Poisson( $\lambda$ = 0.7)

Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)

P(X = 0) = $\frac{e^{-0.7}\times 0.7^{0} }{0!}$

= $e^{-0.7}$ = 0.4966

Hence, the required probability is 0.4966.
