The proportion of waiting times in the sample that are greater than or equal to 18 minutes is 0.16.

<h3>What is a histogram?</h3>

A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.

Number of people whose wait time was equal or greater than 18 minutes / total number of people = (2 + 2) / (6 + 7 + 8 + 2 + 2)

4/25 = 0.16

Convert ( 4 , 300 ∘ ) to rectangular form.

Rasek [7]

The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)

According to the statement

we have given a coordinates of the rectangle and we have to find the polar coordinates.

So, For this purpose, we know that the

We Use the conversion formulas to convert from polar coordinates to rectangular coordinates which are

x = rcosθ

y = rsinθ

Substitute the given values in it then

x=(4)cos(300)

y=(4)sin(300)

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

x=(4)cos(60) -(1)

y= - (4)sin(60) -(2)

And then

x=(4)cos(60)

x=(4)(1/2)

x = 2 -(3)

and

y= - (4)sin(60)

y= - (4)(√3/2)

y= - 2√3 -(4)

Replace (3) with (1) and (4) with (2)

then it becomes

x = 2 and y= - 2√3

The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)

Which binomials below is a factor of this trinomial 5x^2-5x-100

34kurt

We are asked to determine the correct factorization of the given trinomial which is 5x² - 5x -100. The solution to this problem is shown below:
5x² - 5x - 100 let the problem equal to zero such as:
5x² - 5x - 100 = 0 , factor out 5 from the given trinomial
5(x²-x-20) = 0
5 (x-5)(x+4) = 0

The correct factor is 5(x-5)(x+4).

svp [43]

Answer: Y=3, X=5

Step-by-step explanation:

2(2y-1) + 3y=19

4y-2+ 3y=19

7y=21

Y=3

Plug in y in the second equals

X=2(3) -1

X=6-1

X=5

Hope this helps!
