Answer: I am pretty sure the answer is 24

Step-by-step explanation:

So since the two angles are vertical opposite angles, they are congruent angles. Then,

120 = 5x

120/5 = 5x/5

24 = x

A traffic engineer monitors the rate at which cars enter the main highway during the afternoon rush hour. From her data she esti

sertanlavr [38]

Answer:

On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.

Step-by-step explanation:

Given that, the rate R(t) at which cars enter the highway is given the formula

$R(t)= 100(1-0.0001t^2)$

The average rate of car enter the highway during first half hour of rush hour is the average value of R(t) from t=0 to t=30.

$\therefore \int_0^{30} 100(1-0.0001t^2)\ dt$

$=[100(t-0.0001\frac{t^3}{3})]_0^{30}$

$=100[(30-0.0001\frac{30^3}{3})-(0-0.0001\frac{0^3}{3})]$

=2901

The average rate of car is $=\frac{\textrm{The number of car}}{Time}$

$=\frac{2910}{30}$

=97

On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.

liraira [26]

Answer:

A) Gamblers lose a relatively small amount most of the time but there are a few large pay-outs

B) if person play 5 times, the mean of the casino's profit is $0.04

if person play 5 times, the standard deviation of the casino's profit i$268.33

C) If gamblers play this machine 1000 times in a day, the mean is $80

If gamblers play this machine 1000 times in a day, the standard deviation is $3794.3

D) Yes

Step-by-step explanation:

From the details given , it is observed that a casino knows that people play the soft machines in hopes of hitting the jackpot but most of them lose their dollars

There is a certain machine that pays out an average of $0.92 with standard deviation of $120

A) The standard deviation is so large because, Gamblers lose a relatively small amount most of the time but there are a few large pay-outs

B) if person play 5 times, the mean of the casino's profit is

E(x) = ( 1 - $0.92) x 5

= $0.04

if person play 5 times, the standard deviation of the casino's profit is

S(3x) = √120² x 5

= $268.33

C) If gamblers play this machine 1000 times in a day, the mean is

E(x) = ( 1 - $0.92) x 1000

= $80

If gamblers play this machine 1000 times in a day, the standard deviation is

S(x) = √120² x 1000

= $3794.3

D) The casino is likely to be profitable due to the average pays out winning jackpot in slot machines occur very less in $0.29, so more people play winning jackpot in slot machines in casino, the casino will become more profitable.

Triangles ABC and DEF may or may not be congruent, because the angle-angle-angle (AAA) postulate is not a criterion for congruency of any two triangles. This is because the angle-angle-angle postulate only incorporates the angles of the triangles, and the side lengths are not specified, so congruency may or may not be true for these triangles.
