Answer:
Option C is correct.
The total area of the trapezoid = 42 units²
Step-by-step explanation:
After a little research online, the image missing from the question was obtained and is attached to the solution of this question.
In the trapezoid given, there are two triangles and a rectangle.
Area of rectangle = length × breadth
Length = 6 units
Breadth = 5 units
Area of the rectangle = 6 × 5 = 30 units²
Area of a triangle = ½ × Base × Height
Base = 2 units
Height = 6 units
Area of each of the exactly similar triangles = (1/2) × 2 × 6 = 6 units²
Area of the two similar triangles = 2 × 6 = 12 units²
Total Area of the trapezoid = (Area of rectangle) + (Area of the two triangles)
= 30 + 12 = 42 units²
Hope this Helps!!!
Answer:
a) The probability of obtaining a sample mean that is less than or equal to 1770 hours is P(M≤1770)=0.0013.
b) It is unusual, as there are only 13 chances in 10,000 (0.13%) of having this outcome.
Step-by-step explanation:
We have a population lifetime with mean of 1800 hours and standard deviation of 100 hours.
Samples of size n=100 are taken and tested.
We can calculate the probability of obtaining a sample mean that is less than or equal to 1770 hours using a z-score for the sample Mean M=1770 and then calculating its probability according to the standard normal distribution:
Answer:
Part AGroup A is a cluster of points with similar property or relationship.
Point B is an outlier. This is the point outside of the common relationship.Part BThere is a negative tendency. As number of hours spent on computer games increase, the test scores decrease.
Step-by-step explanation:
Part B There is a negative tendency. As number of hours spent on computer games increase, the test scores decrease.
