Answer:
2.33
Step-by-step explanation:
We shall use the z distribution because we know the population standard deviation.
The margin of error formula is given by:
The z-value for 98% confidence interval is 2.326.
The sample size is n=25.
The population standard deviation is is
We substitute the values into the formula to get:
Evaluate square root:
Simplify:
The point-slope form:
We have the slope m = -2 and the point (6, -2). Substitute:
Answer:
The answer is ""
Step-by-step explanation:
The area between two concentrated circles via an exterior circle radius R and an internal circle
The region, therefore, consists of two concentrated circles with radii of 4.5 m and 2.5 m.
Answer:
Definition of mid-point
Step-by-step explanation:
Midpoint is the center point of a line segment
At midpoints the line segment is divided into two equal lengths
Point K is the midpoint of segment MJ and length of segment MK = length of segment KJ
Point K is the midpoint of segment OL and length of segment OK = length of segment KL
Answer:
3.24%
Step-by-step explanation:
Percentage error =[ (|calculated value - actual value) / actual value] x 100
calculated area = length x width
6.5 x 7.8 = 50.7
[(|50.7 - 52.4|] / 52.4] x 100 = 3,24
