The correct answer is option 2.
3 = 0
x - a = 0
x = a
x + b = 0
x = -b
We do not multiply any of these values by 3 because in a way, 3 is acting as another "zero" of the equation. Though, as shown above, it does not equal 0, it still does not apply to any of the other equations solved above.
Hope this helps!! :)
Answer:
Step-by-step explanation:
Normally Z scores in a std normal distribution curve lie between -3 and 3 comprising more than 99% of total area.
Any entry outside (-3,3) can be considered as an extreme observation.
Here we have hence a) -4.3 is the most extreme observation.
-------------------------
Given that 84 separates the lowest 75% of the scores from the highest 25% of the scores,
This means 84 is the 75th percentile and similarly 65 is the 25th percentile.
Thus we have 84 has the percentile rank of 75
Option C
Answer:
x=54/ 7 , 30/7
Step-by-step explanation:
x=54/ 7 , 30/7
Answer:
D
Step-by-step explanation:
The definition a triangle is a shape with three angles and three sides. An example of something in the shape of a triangle is a piece of pizza.
Answer:
see explanation
Step-by-step explanation:
The inscribed angle ABD is on half the central angle ACD, that is
∠ ABD = 0. × 50° = 25°
The measure of arc AD is equal to the central angle it subtends, thus
arc AD = 50°
