Answer:
1.625
Step-by-step explanation:
First we need to find the mean of this data set
29+32+33+28+30+30+29+33=244
Then we divide 244 by the amount of numbers in the set
244/8=30.5
Then we need to find the deviation of each number
29 | 32 | 33 | 28 | 30 | 30 | 29 | 33
1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5
Then we take the mean from this set of data
1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13
Then divide
13/8=1.625
I hope this helps :)

3(y+4)-(x-1)
Let x =3 and y =2
3(2+4) - (3-1)

Answer:
16
Step-by-step explanation:
Evaluate 3 (y + 4) - (x - 1) where x = 3 and y = 2:
3 (y + 4) - (x - 1) = 3 (2 + 4) - (3 - 1)
2 + 4 = 6:
3×6 - (3 - 1)
3 - 1 = 2:
3×6 - 2

The equation which matches the function the function shown in the graph is; Choice A: y = 3sin(x - π).
First, the y-intercept of the function can be evaluated at point, x = 0.
At x= 0; we have;
- y = 3sin(0 - π).
- y = 3sin (-π)
- y = -3 × 0
- y = 0.
Similarly, when x= π;
- y = 3 × 0
- y = 0.
Ultimately, the required function is; Choice A; y = 3sin(x - π).

Answer:
Option A
Step-by-step explanation:
You can simply check by using options
- The function must be sine because the graph passes through origin
- So, answer will be in A& B

Answer:
A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. A square however is a rhombus since all four of its sides are of the same length.
Step-by-step explanation:
Hope thats helpful! :)
you can find the answer to this by looking at the properties of both shapes. a rhombus has Opposite sides that are parallel, Adjacent angles are supplementary, All the four sides are equal, and all 4 sides bisect forming right angles. a square also has these properties therefore a square can classify as a rhombus. but be careful, just because a square is a rhombus, it doesn't always necessary mean that a rhombus is always a square

The product of the slopes of perpendicular lines equals -1
Solution:
Need to determine product of slope of perpendicular lines.
Product of slopes of perpendicular lines is always equal to -1.
lets verify this.
let consider following two equation of perpendicular lines
2x – y = 1
x + 2y = 2
Now evaluate slope of each line by representing them in slop intercept form that is y = mx + c
Where coefficient of x represents slope m.
Representing first line in slope intercept form we get
y = 2x – 1
On comparing above equation with slope intercept form we can say that its slope is 2.
Similarly representing x + 2y = 2 equation in slope intercept form we get
On comparing above equation with slope intercept form we can say that its slope is
On multiplying slopes of two perpendicular lines we get,
Hence product of slope of perpendicular line is -1
If two non-vertical lines are perpendicular, then their slopes are opposite reciprocals giving you -1.
:) Hope this helps.
