A) 1.0 mile <br>b) 5.0 mile <br>c) 5.8 mile <br>d) 0.8 mile

nordsb [41]

Answer:

d) 0.8 mile

Step-by-step explanation:

Coordinate of object B = (6, 6)

Coordinate of object C = (1, 4)

Coordinate of the archaeologist = (6, 1)

✍️Distance between Object B (6, 6) and the archaeologist (6, 1):

Distance = |6 - 1| = 5 units = 5 miles

✍️Distance between Object C (1, 4) and the archaeologist (6, 1):

Using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , we would have:

$d = \sqrt{(6 - 1)^2 + (1 - 4)^2}$

$d = \sqrt{(5)^2 + (-3)^2}$

$d = \sqrt{25 + 9}$

$d = \sqrt{34} = 5.8 units = 5.8 miles$ (nearest tenth)

Comparing how far each object is from the archaeologist, object C is 0.8 mile (5.8 - 5 = 0.8) farther than object B.

The waiting time at an elevator is uniformly distributed between 30 and 200 seconds. What is the probability a rider must wait b

serg [7]

Answer:

17.65% probability a rider must wait between 1 minute and 1.5 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is between c and d is given by the following formula

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

For this problem, we have that:

$a = 30, b = 200, c = 1*60 = 60, d = 1.5*60 = 90$

$P(60 \leq X \leq 90) = \frac{90 - 60}{200 - 30} = 0.1765$

17.65% probability a rider must wait between 1 minute and 1.5 minutes
