Answer:

The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!\cdot (n-k)!}$

Compute the number of ways to select 37 people from 101 as follows:

${101\choose 37}=\frac{101!}{37!\cdot (101-37)!}$

$=\frac{101!}{37!\times 64!}\\\\=\frac{101\times 100\times 99\times....64!}{37!\times 64!}\\\\=5397234129638871133346507775$

Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

acme lumber purchased 13.145 pine wood and 16.903 cedar wood to sell in the store. after 6 months they had sold7.589 pounds of l

11111nata11111 [884]

Answer:

22.459 pounds of wood

Step-by-step explanation:

Total amount of wood in store = amount of pine wood purchased + amount of cedar in the store

Total amount of wood in store = 13.145 pine wood + 16.903 cedar wood

Total amount of wood in store = 30.048 pounds of wood

If acme lumber had sold 7.589 pounds of lumber after 6 months, the amount of pounds of woods that the company have left to sell = Total amount in store initially - amount sold after 6 months

Amount of pounds of woods that the company have left to sell = 30.048 - 7.589

The amount of pounds of woods that the company have left to sell = 22.459 pounds of wood
