$|\Omega|=30\\ |A|=24\\\\ P(A)=\dfrac{24}{30}=\dfrac{4}{5}=0.8$

Sonbull [250]

Answer:

The power of horse is: P = 72000 W

Step-by-step explanation:

Given

F = 1800 N

v = 40.0 m/s

To determine

P = ?

Using the formula

$\:\:\:P=\overrightarrow{F\cdot }\overrightarrow{v}$

The ⋅ in the formula represents a scalar product, defined by:

$\overrightarrow{v\cdot }\overrightarrow{w}=|v||w|cos\:\theta$

The angle Ф is zero because F and v are are parallel.

Thus the cosine is 1.

Therefore,

P = (1800) (40.0)

P = 72000 W

Hence, the power of horse is: P = 72000 W

Debora [2.8K]

Answer:

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$

Step-by-step explanation:

Let

x------> the total students in Marla's school

we know that

The number of students that not ride the bus is equal to

$\frac{6}{15}x\ students$

The number of students that walk to the school is equal to

$\frac{6}{15}x*\frac{5}{9}=\frac{2}{9}x\ students$

therefore

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$
