Only take the first numbers into consideration. For the last 2 you have to consider 5 numbers and two places to the right of the decimal.
the probability that exactly 1 received a special accommodation is 0.3079
Step 1: define the variable
x= the number of students who received a special accommodation.
Step 2: define the distribution of this variable
x ~ binomial distribution ( p=0.02, n=25)
this is because x is the number of succes in 25 trials.
Step 3: using the binomial distribution formula
where (25C1) is a combination
So, we know the area is 24, and the length is 2 more than the width. Let's refer to the width as x, and the length as x+2. In a rectangle, area is length times width. So, let's multiply the length and width to get x + 4. This is because any number times itself is that number squared. Now that we have that, solve for x. Subtract 4 from both sides of the equation and get x Now we have . What we do next is do the square root of both sides, in order to get x by itself. this gives us the answer of . That is the width of the rectangle. If you want to go further, we can simplify the expression. 20 is 4*5, and 4 is a square number. We can rewrite the expression now as x=. We know the square root of 4 is 2, but the square root of 5 is too difficult to work with and get an exact answer, so we can leave that as-is. our final answer for the width of the rectangle is . I hope this helps!
Step-by-step explanation: if you pay attention to this answer its for points thanks
We have : 2x = 5 ⇔ x = 5/2
3y = 4 ⇔ y = 4/3
4z = 3 ⇔ z = 3/4
⇒ 24xyz = 24 × 5/2 × 4/3 ×3/4 = 60
