The given known values are: Length of 4 cm Width is unknown Perimeter is 34 cm Find the dimensions of the rectangle.   Since the geometric formula for perimeter is:
P= 2 (l + w)
L = 2w – 4 cm
W =?  
Derivation and solution:
34 = 2 (2w - 4) + 2w <span>
34 =  4w – 8 + 2w</span>
42 = 6w 42/6 = w
W = 7 cm  

34 = 2l + 2(7)
34 = 2l + 14
2l = 34 – 14
2l = 20
L = 20/2
L = 10 cm

Answer: 23.4 ft^3

Step-by-step explanation: The perimeter of the base is 10.7, it is a square so the 4 sides of the base are equal. One side of the base is equal to 2.675 if the perimeter (4 sides) is equal to 10.7, so plug that and the height into the formula for the volume of a square pyramid to get 23.38, or 23.4 to the nearest tenth.

A jury pool has 17 men and 18 women, from which 12 jurors will be selected. Assuming that each person is equally likely to be ch
Svetach [21]

Answer:

0.86

Step-by-step explanation:

To find this, we need to know the number of ways the jury can be picked overall, and then the number of ways 8 men and 4 women can be on the jury. The fraction of the two will be the probability.

The total number of ways the jury can be picked is the combination of a pool of 35 people and choosing 12 is; C(30,12) = 30!/((12!)(30 - 12)!)

= 86,493,225

We have gotten the number of ways the jury can be picked.

Now let's find how many ways can the jury consist of 8 men and 4 women.

For the men, there are 17 in the pool and we're picking 8:

Thus, C(17,8) = 17!/((8!)(17 - 8)!) = 24,310

For the men, there are 18 in the pool and we're picking 4:

Thus, C(18,4) = 18!/((4!)(18 - 4)!) = 3,060

Thus, number of men and women choices = 24,310 x 3060 = 74388600

So; probability = 74388600/86,493, 225 = 0.86
