The simplest method to find a rational number between two rational numbers x and y is to divide their sum by 2.
Answer:
they will eat 12 food altogether
10% = 0.1
10% of 5 = 10% x 5 = 0.1 x 5
therefore, the answer is $0.50
Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:

Answer:
We need to know angle C which is (180 -123 -34) = 23°
We'll use the Law of Sines
Sine (A) / side a = Sine (B) / side b
Sine (34) / 10 = Sine (123) / side b
0.55919 / 10 = 0.83867 / side b
10 * .83867 / .55919 = side b
side b (or line AC) = 14.998
