Are perpendicular to each other
Answer:
Steps :
1. Create an equation
If x-4=0 and y-10.4=0, then x - 4 = y - 10.4
2. Isolate variable X by adding 4 to both sides
3. (Optional) Check Answer by plugging given values into the equation
4 = 4 is a true statement
Answer: (n2+1) (n+1) (n-1)
Step-by-step explanation:
Answer:
Area= 97.9 km²
Step-by-step explanation:
Angle at w = 180-119-34
Angle at w = 27°
Side XV= x
x/sin27= 26/sin119
x= sin27(26/sin119)
x= 0.454(26/0.8746)
x= 13.5 km
Side WX = y
y/sin 34= 26/sin119
y= sin34(26/sin119)
y= 0.559(26/0.8746)
y= 16.6 km
S= (16.6+13.5+26)/2
S= 56.1/2
S=28.05
Area = √(28.05(28.05-26)(28.05-13.5)(28.05-16.6))
Area=√(28.05(2.05)(14.55)(11.45))
Area=√(9579.772744)
Area=97.8763
Area= 97.9 km²
Answer:
The median is 150 minutes.
Step-by-step explanation:
As we know, in our question, we have been told that the distribution of time on social media is known to be NORMAL. So, it’s a NORMAL DISTRIBUTION. And there is a property of normal distribution that it’s mean is equal to median which is also equals to mode.
So we can conclude that:
For Normal Distribution:
Mean = Median = Mode
So, in our question average = 150 minutes = mean
So, according to the property of normal distribution:
Mean = 150 minutes = Median
