Answer:
22
Step-by-step explanation:
first side plus second side has to be less then the third side
15 + 6 = 21
third side can be greater or equal to 22
2 hours and 50 minutes would be the answer. MST is one hour behind CST, so you would add an hour to 5:30 to basically make them the same time zone. Then you find the time between 9:20 and 6:30 to get 2 hours and 50 minutes.
If we consider the positive value of b, then the value of b is 4.
<h3>What is the coordinate plane of a complex number?</h3>
A complex number in the form z = x + iy takes a coordinate plane in terms of (x,y). From the given information, we are given a distance between two points:
- 25 + bi = (25,b)
- 13-31i = (13, -31)
Now, the distance between two points can be represented by using the relation:
Taking the square of both sides
1369 = 144 + (31 + b)²
1369 - 144 = (31 + b)²
1225 = (31 + b)²
(31 + b)² = (35)²
(31 + b) = ±35
b = 35 - 31 or -35 -31
b = 4 or -66

Answer:
19.2
Step-by-step explanation:
You get the mean of a set of numbers by adding them and dividing the sum by how many numbers there are. In this case, you don't know what the individual 8 numbers are, but you can find out what they add up to.
Mean = (sum) / 8
17 = (sum) / 8
17 x 8 = sum
136 = sum
Now take out the numbers 9, 11, 20, which reduces the sum by 40. There are 5 numbers left and they add up to 136 - 40 = 96.
The new mean is 96 / 5 = 19.2
