The probability of rolling an even number is three times (2,4,6) and the probability of rolling a number less than 5 is 4 times (1,2,3,4)

Not sure if I'm right or not but I hope this helps :)

Answer:

Even Number - 3/6 or 1/2

Number less than 5- 4/6 or 2/3

Step-by-step explanation:

Even Number- There are 3 even numbers on a die (2, 4, and 6) and its 6 number in total on a die o its 3/6 or 1/2.

Number Less Than 5 - For a number LESS than 5 (1, 2, 3, and 4) and its 6 numbers on the die in total so its 4/6 or 2/3.

Answer:

Train A's unit rate is 67 km per hour.

Train B's unit rate is 75 km per hour.

Train B is faster than Train A

Step-by-step explanation:

Train A

Distance traveled by Train A is represented by :

$d=67t$

where $d$ represents distance traveled in kilometers and $t$ is the time in hours.

To find the unit rate of Train A, we will plugin $t=1$ and get the distance traveled by Train A in 1 hour which will be the unit rate of Train A in km/hr.

$d=67(1)$

$d=67$

So, distance traveled by Train A in 1 hour = 67 km

∴ Train A's unit rate is 67 km per hour.

Train B

For Train B, we are given the table for the time in hours and distance traveled in that duration.

Taking time =2 hours the distance traveled by Train B= 75 km

To find distance traveled in 1 hour we apply unitary method.

$2\ hr = 150\ km$

So $1\ hr = \frac{150}{2}\ km = 75\ km$

So, distance traveled by Train B in 1 hour = 75 km

∴ Train B's unit rate is 75 km per hour.

Difference in units rates = $75-67=8\ km/hr$

On comparing their unit rate i.e. the speed of the trains we find out that Train B is faster than Train A by 8 km/hr

Which statement regarding the diagram is true? m∠WXY = m∠YXZ m∠WXY < m∠YZX m∠WXY + m∠YXZ = 180° m∠WXY + m∠XYZ = 180°

elena55 [62]

In the given question, the options are related to linear pair .

And according to linear pair, if a line cuts another line at a point, then the sum of the adjacent angles formed at that point is 180 degree.

Therefore, from the given diagram we can say that, angles WXY and YXZ are linear pair, so there sum have to be 180.

$\angle WXY + \angle YXZ =180$

And the correct option is the third option .
