An event has a theoretical probability of 0.5. what does this mean?

1 answer:

3 0

Answer: A probability of 0.5 means that an event is as likely to happen as it is likely to not happen.

This is a chance of having a 50/50 probability. This means that there is a 1/2 chance of a favorable outcome. And also 1/2 chance of a non-favorable outcome.

1. The formula for the velocity of an object is d=v/t, where v is the object, d is the distance traveled, and t is the time the

Arlecino [84]

Answer:

you need to isolate t or time

you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth

Step-by-step explanation:

$t*(d)=(v/t)*t\\td= v\\\\\frac{td}{d} =v/d \\t=v/d$

to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself

now you mulipy d to both side to get v over d and time by itself

Which expression can be used to find the surface area of the following square pyramid?

telo118 [61]

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4. Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides. Thus, the total slant surface area is 4(10 units^2), or 40 units^2.

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.
