Detailed explanation:
Work completed by Gardner each hour = 1 / 5
Combined work done by Gardner and assistant each hour = 1 / 4
Work done by the helper per hour
= 1 / 4 - 1 / 5
= 1 / 20
Time required for helper to finish the job:
= 20 hours
Response: Annabelle is employing the statistical concept known as Mode.
Detailed explanation: A central tendency measure, in its most basic sense, is a singular value or measure that effectively represents all elements of a particular data set. As such, one number can serve to essentially represent 99 other numbers in a data set of one hundred figures.
Commonly acknowledged measures of central tendency include mean, median, and mode.
The mode denotes the value that appears most often in a data set. Therefore, the modal value is statistically suitable as a representative of the entire group of values or data points.
If Annabelle measures the sides of 15 right triangles and concludes that the sum of the squares of the two legs is equal to the square of the hypotenuse for any right triangle, she is identifying the most frequently occurring value, and in her analysis, the most common data observed aligns with the Pythagorean Theorem.
This is why Annabelle's assumption is made with confidence.
I think the correct solutions are: UV = 14 ft and m∠TUV = 45°; ST = 20 ft, UV = 14 ft, and m∠UST = 98°. In other words, Options A and D.
Each month she puts in 20......therefore annually she deposits (20 * 12) = 240 y = 240x + 200
