It is a trinomial because it follows the pattern of x^2 + bx + c. In this case, x^2 - 10x + 25. Also, it only has three numbers and two operation symbols, signifying a trinomial (three = tri).

32.6 = 17.3 + -1d
Solving
32.6 = 17.3 + -1d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add 'd' to each side of the equation.
32.6 + d = 17.3 + -1d + d
Combine like terms: -1d + d = 0
32.6 + d = 17.3 + 0
32.6 + d = 17.3
Add '-32.6' to each side of the equation.
32.6 + -32.6 + d = 17.3 + -32.6
Combine like terms: 32.6 + -32.6 = 0.0
0.0 + d = 17.3 + -32.6
d = 17.3 + -32.6
Combine like terms: 17.3 + -32.6 = -15.3
d = -15.3
Simplifying
d = -15.3</span>
Answer:
distance across the pond: 13 yd
distance walked by Garret: 12 yd
Step-by-step explanation:
Data:
- distance across the pond: x yd
- distance walked by Sandy: 5 yd
- distance walked by Garret: x-1 yd
A right triangle is formed where the distance across the pond is the hypotenuse. From Pythagorean theorem:
x² = 5² + (x-1)²
x² = 25 + x² - 2x + 1
0 = 26 - 2x
x = 13
Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.
Step-by-step explanation:
Hope this helps!
