It would be -1/2 because the formula to find slope (rate of change) is (y2-y1)/(x2-x1) and in this case it would be (4.5-2)/(-3--2) which simplifies to (2.5)/(-5) which is -1/2
Answer:
Second Attempt is faster.
Step-by-step explanation:
He reads 360 words in hour in the first attempt and in the second attempt he reads the same number of words in hour.
Since, he takes less time in the second time. Less time means the work is done faster.
Therefore, second attempt is faster.

What are the coefficients in the polynomial 4x²+3x-3?
<u>Coefficient:-</u> A number before a variable
<u>Coefficients in this polynomial:-</u>
4 (the number before x²) and 3 (the number before x)
<h3 />
So we conclude that the right option is:-
4, 3 (Option B)
<h3>Good luck.</h3>

Answer:
Option: C is the correct answer.
C. Buying a needle and buying thread are dependent events.
Step-by-step explanation:
let A denotes the events of buying a thread.
and B denote the event of buying a needle.
Then A∩B denote the event of buying a needle and a thread.
Also let P denote the probability of an event.
i.e. we are given:
P(A)=0.15
Also P(B|A)=0.25
As we know that:
As we know that when two events A and B are independent then,
P(A∩B)=∅
otherwise they are dependent events.
Hence, option: C is the correct answer.
