Rachel has 10 sweets in a bag.
1 answer:
Using it's concept, it is found that there is a 0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.
<h3>What is a probability?</h3>A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, we have that:
- One sweet, the probability is 3/10.
- For two, the probability is 7/10 then 3/9.
- For three, it is 7/10 then 6/9 then 3/8.
So:
0.713 = 71.3% probability that Rachel takes no more than three sweets from the bag.

The area of the square increasing at 30
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square =
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9 the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30
Thus the area of the square increasing at 30

Hey there!
For questions like these, we want to isolate the x on one side of the equation and have everything else on the other side.
Let's add both sides by 2 to eliminate the "-2"
Now, let's divide both sides by 5 to eliminate the "5" in front of the x.
That's your answer.
Have an awesome day! :)
