Answer:

8 m/s^2

Step-by-step explanation:

You can use the equation a = v^2 / r

That is acceleration is equal to velocity squared divided by the radius which in this problem is the length of the string. The velocity is 4m/s and the r the radius is 2 m. Now you can square 4 m/s to get 16 m^2/s^2 THEN you divide by 2 m and the m^2 turns to just m and the 16 to an 8. So, that leaves you with acceleration or in this case centripetal acceleration equals 8 m/s^2.

a = 8 m/s^2 or 8 meters per second squared.

Monk crossbred plants, which can have purple or white flowers, and obtained 639 plants with white flowers and 280 plants with

ira [324]

Answer:

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$

Step-by-step explanation:

There are

639 plants with white flowers
280 plants with purple flowers
919 plants in total.

The <u>empirical probability</u> of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$
