Answer:

9\picentimeters squared or 28.27 centimeters squared

Step-by-step explanation:

The formula for volume is r^{2} \pi h. The radius is 3 and the height is 1 so it is 3^{2} \pi 1 which equals 9\pi. 9\pi is roughly 28.27.

8:00 to 11:00 = 3hrs
11:00 to 12:00 = 1hr
12:00 to 4:00 = 4hrs

3hrs + 1hr + 4 hrs = 8hrs
In minutes, 8 hrs will be 480mins.

A town recently dismissed 9 employees in order to meet their new budget reductions. The town had 7 employees over 50 years of ag
raketka [301]

Answer:   0.1340

Step-by-step explanation:

The binomial distribution formula is given by :-

P(x)=^nC_xp^x(1-p)^{n-x}, where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.

Given : The number of employees over 50 years of age =7

The probability of employees over 50 years of age = \dfrac{7}{7+15}=0.318

Number of dismissed employees : n= 9

Now, the required probability will be :

P(x =1)=^{9}C_1(0.318)^{1}(1-0.318)^{9-1}\\\\=(9)(0.318)(1-0.318)^{8}=0.133950588714\approx0.1340

Thus, the probability that exactly 1 employee was over 50 = 0.1340
