Hello!
As you cans see, the angle is a right angle, which measures 90°. One of the angles measure 35°
90 - 35 = 55
That means 5x = 55°
Divide both sides by 5
Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
So, you for given conditions, you can't travel more then 35.3 miles
So, the inequality for the given circumstances is:
x ≤ 35.2
X+4x+6x=
All of the variables are x so you don't have to do anything
6x+4x=10x
there is still one x left
x = 1
10x+x = 11x
You would do 78/4 which equals 19.5. Hope this helps!
ANSWER
1 bell shape
2 to find probability when sampling
EXPLANATION
1 In a normal distribution, the mode,mean and median are equal.
As a result, the distribution is neither skewed to the right or left.
The shape of the normal distribution looks like a bell.
That is why it is also called the bell curve.
2. The area under the normal curve is 1.
The line of symmetry of the bell shaped distribution divides it into two halves with area 0.5 each.
The normal curve is therefore used to find the probabilities of a sample distributions.
