Example-A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Answers- A, C, D and E
Answer:
t = 2.25
Step-by-step explanation:
To find t, divide each side by 4.
9 = 4t
Divide 9 by 4:
2.25 = t
So, t = 2.25
Refer to the diagram shown below.
The height of the pole is CD (3 m), and its shadow is AB (1.22 m).
The height of the building is h m, and its shadow is AD (38.5 m).
The two triangles ΔABC and ΔADE are similar because of AAA.
Therefore

Cross multiply.
1.22 h = 3*38.5 = 115.5
h = 115.5/1.22 = 140.91 m
Answer: 141 m (nearest meter)
Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation
.
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)
