Answer:
finite set is this
Step-by-step explanation:
even number less than 50 is finite set
Answer:
option C
0.531
Step-by-step explanation:
Given in the question,
total number of people of age 35 years = 162
Total number of people of age 35 and having haemoglobin 9 or above
162 - 76
86
probability = 86/162
= 0.531
Answer:
Option B. Standard error of predicted amount.
Step-by-step explanation:
A standard error predicted amount will work best in this scenario. The data, when extracted from the standard mean, provides the most accurate presentation of the statistical data on question. By using the standard error, the variation from the central point can be determined.
Answer:
Step-by-step explanation:
Using the formula for calculating the distance between 2 points.
D = √(x2-x1)²+(y2-y1)²
Given
D = 45 units
The coordinates Q(–1, a) and P(3,2)
45 = √(3-(-1))²+(-2-a)²
45 = √4²+(-2-a)²
45 = √16+(-2-a)²
45² = 16+(-2-a)²
45² = 16+4+4a+a²
45² = 20+4a+a²
a²-4a+20-2025 = 0
a²+4a-2005 = 0
a = -4±√16+4(2005)/2
a = -4±√16+8020/2
a = -4±√8036/2
a = -4±90/2
a = -4+90/2
a = 86/2
a = 43
The possible values of a is 43
Place the compasses on the given external point R.
