Answer:
y^7
Step-by-step explanation:
Answer:
x = 11√3
y = 22
Step-by-step explanation:
In a 30-60-90 triangle, the hypotenuse is twice the shortest side.
y = 22
The long side is √3 times the short side.
x = 11√3
If you wish to use trigonometric functions:
sin 30° = 11 / y
1/2 = 11 / y
y = 22
tan 30° = 11 / x
1 / √3 = 11 / x
x = 11√3
Answer:
D) -1.8, -1 1/2 , 0.3 , 3/4 , 1
Step-by-step explanation:
Change all of the given terms to either fractions or decimals. Generally decimals are easier:
3/4 = 0.75
-1.8 = -1.8
1 = 1.0
-1 1/2 = -1.5
0.3 = 0.3
Order from least to greatest:
-1.8 , -1.5, 0.3 , 0.75 , 1.0
or
-1.8, -1 1/2 , 0.3 , 3/4 , 1

You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .
The first 3 months are 250
6 months are 500
9 months are 1000
12 months are 2000
15 months are 4000
18 months are 8000
21 months are 16000
24 months are 32,000 which is two years
