12/8 is the correct answer
hope this helps :)
The range of her scores is 17.
<em><u>Explanation</u></em>
Mindy's scores in five tests are: ![95, 86, 78, 80, 91](https://tex.z-dn.net/?f=95%2C%2086%2C%2078%2C%2080%2C%2091)
First, rearranging the data in numerical order, we will get ........
![78, 80, 86, 91, 95](https://tex.z-dn.net/?f=78%2C%2080%2C%2086%2C%2091%2C%2095)
<u>'Range' is the difference between the highest and lowest values</u>.
In the above data set, highest value is 95 and lowest value is 78
So, the range of her scores will be: ![95-78= 17](https://tex.z-dn.net/?f=95-78%3D%2017)
Answer:
The answer to your question is: length = 10.4 units
Step-by-step explanation:
Data
It's a right triangle with angles 30°- 60°- 90°
I'll solve this exercise with the function sine and cosine
a) sin 60 = long leg / hypotenuse
long leg = hypotenuse x sin 60
long leg = 12 x 0.87
lon leg = 10.4 units
b) cos 30 = long leg / hypotenuse
long leg = hypotenuse x cos 30
long leg = 12 x 0.87
long leg = 10.4 units
3 kilograms = 4.86
So one kilogram = 4.86/3 = 1.62
2 kilograms = 1.62 × 2 = 3.24
Making an equation,
Let heralds age be x
10+6x=4x+40
Seperating constants and variables,
6x-4x=40-10
2x=30
x=30/2
=15
Heralds age is 15,
Substitute x with 15 in the equation for rechecking
