Answer:
Option C is right
Step-by-step explanation:
Given that the random variable, X, the ages of voters as per poll worker analysis is having mean as 65 and std deviation as 5
X is normal (65,5)
To convert to Z score from x we use
Z =
Or we can write in terms of x as
X = 65+5z
When z = 1.14
we can convert into z as follows
X=65+5(1.14) = 65+5.7=70.70
Round off to 71
Answer:
y=2
Step-by-step explanation:
To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:
Since the slop is 0, this is a horizontal line of the form y=b. B is the y-intercept of the points on the line. Notice that both are 2? y=2
Answer:
3.57 miles
Step-by-step explanation:
Please consider the attachment.
We have been given that a campsite is 12.88 miles from a point directly below Mt. Adams. The angle of elevation is 15.5° from the camp to the top of the mountain. We are asked to find the height of the mountain.
We can see from the attachment that h is opposite side to angle 15.5 degrees and 12.88 miles in adjacent side.
We know that tangent relates opposite side of right triangle with its adjacent side.
Therefore, the mountain is approximately 3.57 miles high.
