iogann1982 [59]

Answer:

given sequence, -16; -9; -2: _

first term(a)=-16

common difference(d)=-9-(-16)=7

next term is 4

4th term=a+(n-1)d

=-16+(4-1)7=-16+21=5

Which of the following pairs of angles are supplementary? Select all that apply.

4vir4ik [10]

Supplementary angles mean they equal 180 degrees which means any two angles that equal a line. so that would be:
<1 and <3
<1 and <4
<2 and <3
and <2 and <4

as all of these angles (in their respective pairs) create a single line which is equivalent to 180 degrees

Find the midpoint of a segment with endpoints (-9, 3) and (5, 7). <br><br> I need help ASAP pleasee

vfiekz [6]

Answer:

( -2,5)

Step-by-step explanation:

To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2

( -9+5)/2 = -4/2 = -2

To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2

( 3+7)/2 = 10/2 = 5

The midpoint is ( -2,5)

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
