<span>The standard deviation can be zero if all the data points are the same. Thestandard deviation can be larger than the mean. The range of numbers has to be large for this to occur. One such sample is {0, 0, 1, 15, 20}, where = 7.2 and s 8.6.</span>
Plug in x with -1
A negative number in parenthesis times an exponent is always positive.
8+3-7=4
Answer:
See below
Step-by-step explanation:
√160c⁵d⁴
= √160 * √c⁵ * √d⁴
= √16 * √10 * √c² * √c² * √c * √d² * √d²
= 4 * √10 * c * c * √c * d * d
= 4c²d²√10c
Answer:
Long diagonal: 12.12 yd
Short diagonal: 7 yd.
Step-by-step explanation:
As you can see, 4 righ triangles are formed.
The larger diagonal divides the angle ∠AFM=60° into two angles of 30° each.
Then, choose one the triangles that has the angles of 30°. The hypotenuse will be the side lenght of 7 yards, the long diagonal (D) will be twice the adjacent side and the short diagonal (d) will be twice the opposite side.
Then:
- Long diagonal:
- Short diagonal:
