Answer:1. The coordinates of Jo’s house are (-4,-2).
Step-by-step explanation:
1. Since Jo’s house is reflected across both axes, we must reflect the coordinates two times. So we can reflect the coordinates of Kianna’s house across the x-axis first, which would give you the coordinates (4,-2). Then we reflect (4,-2) across the y axis, giving us the coordinates (-4,-2). So Jo’s house has the coordinates (-4,-2).
Hope this helps.
Answer:
Step-by-step explanation:
Let represent students playing basketball, represent students playing baseball.
Then, ,
Let be the total number of students. So, .
Now,
3 students play neither of the sport. So, students playing either of the two sports is given as:
∴
From the probability addition theorem,
Where, is the probability that a student chosen randomly from the class plays both basketball and baseball.
Plug in all the values and solve for . This gives,
Therefore, the probability that a student chosen randomly from the class plays both basketball and baseball is
