the second longest bridge in the world, the tianjin grand bridge, is 373,000 feet long. Its length is 167,700 feet less than the
Mademuasel [1]
If something is 167,700 feet less than something then the value of the longer object would be the that much more than the length of that shorter object. In this case it would be 373,000 + 167,700 = 540,700 ft.

This question is Incomplete

Complete Question

Researchers recorded the speed of ants on trails in their natural environments. The ants studied, Leptogenys processionalis, all have the same body size in their adult phase, which made it easy to measure speeds in units of body lengths per second (bl/s). The researchers found that, when traffic is light and not congested, ant speeds vary roughly Normally, with mean 6.20 bl/s and standard deviation 1.58 bl/s. (a) What is the probability that an ant's speed in light traffic is faster than 5 bl/s? You may find Table B useful. (Enter your answer rounded to four decimal places.)

Answer:

0.7762

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Population mean = 6.20 bl/s

Standard deviation = 1.58 bl/s.

x = 5 bl/s

z = 5 - 6.20/1.58

z = -0.75949

The probability that an ant's speed in light traffic is faster than 5 bl/s is P( x > 5)

Probability value from Z-Table:

P(x<5) = 0.22378

P(x>5) = 1 - P(x<5)

= 1 - 22378

= 0.77622

Approximately to 4 decimal places = 0.7762

The probability that an ant's speed in light traffic is faster than 5 bl/s is 0.7762

What is the exact volume of the cone
Travka [436]

Answer:

V = \frac{400}{3}\pi

Step-by-step explanation:

Volume of a cone is:

V = \pi r^{2} \frac{h}{3}

Substitute values given:

V = \pi (5^{2} )(\frac{16}{3})

V = \pi (25)(\frac{16}{3} )

V = \pi \frac{400}{3}

V = \frac{400}{3}\pi
