The wind was blowing quite strongly when jenny was baby-sitting. she was outside with the children, and they were throwing their large plastic ball up into the air. the wind blew the ball so that it landed approximately 3 feet east and 4 feet north of where it was thrown into the air.

d.

Step-by-step explanation:

We are given that the wind blew the ball so that it landed approximately 3 feet east and 4 feet north of where it was thrown into the air.

We know that East is at the right which can be shown by positive value of x while North is upwards so it can be shown by addition in the value of y.

Therefore, the correct answer option is:

d.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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
