For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are
of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
Example:![3: 1 = 3 * 2: 1 * 2 = 6: 2](https://tex.z-dn.net/?f=3%3A%201%20%3D%203%20%2A%202%3A%201%20%2A%202%20%3D%206%3A%202)

Answer: 20.67

Gradient of AB = y1-y2/x1-x2
= -3-0/1-1
= -3/0
gradient of AB = gradient of CD (as AB is parallel to CD)
therefore D = 3+y3/0+x3
= -3+2/0+4
= -1/4
since y/x of D = -1/4,
the coordinates of D is (4,-1) [option B]

Answer:
The answer is the Last Graph
D
Step-by-step explanation:
The '68-95-99.7 ' rule says,
-About 68% of values fall within one standard deviation of the mean.
-About 95% of the values fall within two standard deviations from the mean.
-Almost all of the values — about 99.7% — fall within three standard deviations from the mean.
Here
![27.8=29-1*1.2](https://tex.z-dn.net/?f=%2027.8%3D29-1%2A1.2%20)
The length falls within one standard deviation of the mean.
Therefore, the probability ![P(27.8](https://tex.z-dn.net/?f=%20P%2827.8%3CL%3C30.2%29%3D0.68%20)
The required probability is
![P(L](https://tex.z-dn.net/?f=%20P%28L%3C27.8%29%3D%5Cfrac%7B1-0.68%7D%7B2%7D%3D0.16%20)
