The mode of his grade is 90 because it is the number most frequented
Answer:
1
Step-by-step explanation:
Since, line is intersecting y axis at (0, 1).
Therefore, y-intercept of the graph is 1.
Answer:
Y || Z
Step-by-step explanation:
We know that Y⊥B, and Z⊥B, which means both Y and Z are perpendicular to B, meaning that they both create 90° angles with B, and from that, we can make the conclusion that Y || Z
Using a system of linear equations, the distance between points A and B is 6000 cm
Time taken = Distance / speed
Let ; distance = d
<u>To</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>
- <u>t</u> = d / 4
- <em>4t = d ______(1)</em>
<u>Fro</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>
(t + 15 × 60) = d / 2.5
2.5(t + 900) = d
<em>2.5t + </em><em>2250</em><em> = d ______(2)</em>
Equate (1) and (2)
4t = 2.5t + 2250
4t - 2.5t = 2250
1.5t = 2250
t = 1500 seconds
From (1) :
d = 4t
d = 4(1500)
d = 6000 cm
Therefore, the distance from point A to B is 6000 cm
