Answer:

8.71 x 10^3N - C

Step-by-step explanation:

Force = mass x acceleration

mass = 1.7 x 10^3 and acceleration = 4.75m/s^2

Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N

Answer:

8,075N

Step-by-step explanation:

The information we have is:

Mass:

$m=1.7x10^3kg$

Acceleration:

$a=4.75m/s^2$

We are asked to find the force that is necessary to create that acceleration in the given mass.

For this we use the equation of Newton's second law:

$F=ma$

and now we susbtitute all the values into the equation to find the force $F$ :

$F=(1.7x10^3kg)(4.75m/s^2)\\F=8,075N$

The magnitude of the force required is 8,075N

Final exam scores are normally distributed with a mean of 74 and a standard deviation of 6. Approximately, what percentage of fi

notka56 [123]

Answer:

81.86%

Step-by-step explanation:

We have been given that final exam scores are normally distributed with a mean of 74 and a standard deviation of 6.

First of all we will find z-score using z-score formula.

$z=\frac{x-\mu}{\sigma}$

$z=\frac{68-74}{6}$

$z=\frac{-6}{6}=-1$

Now let us find z-score for 86.

$z=\frac{86-74}{6}$

$z=\frac{12}{6}=2$

Now we will find P(-1<Z) which is probability that a random score would be greater than 68. We will find P(2>Z) which is probability that a random score would be less than 86.

Using normal distribution table we will get,

$P(-1$
