On tuesday at 2 p. m., the ocean’s surface at the beach was at an elevation of 2.2 feet. winston’s house is at an elevation of 12.1 feet. the elevation of his friend tammy’s house is 3 1/2 times the elevation of winston’s house. how many times greater is the elevation of winston’s house than the elevation of the ocean’s surface at 2 p. m.?

wouldnt the answer be 9.9

Step-by-step explanation:

12.1-2.2=9.9

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
