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 smallest angle of rotational symmetry for a square
mars1129 [50]

When we rotate a figure and there is no change in the shape of the figure then it has rotational symmetry.

We know that the order of rotation for a square is 4.

Hence, we have \frac{360}{4} =90^{\circ}

Thus, the angle of rotational symmetry of square are

90^{\circ}, 180^{\circ}, 270^{\circ}

Hence, the minimum angle  of rotational symmetry is  90^{\circ}

Therefore, the minimum angle of rotational symmetry for a square is 90 degrees.

Find X. please i need help with this
-BARSIC- [3]

Answer:

Step-by-step explanation:

X + X + 96 = 180    {SUM OF ANGLES OF TRIANGLE}

2X + 96 = 180

2X = 180 -96

2X =84

X = 84/2

X = 42
