11) 24 : 5

12) 36 : 5

13) 7 : 3

14) 15 : 1

<u>Ratio = Number of event 1 : Number of event 2</u> (in same unit, if necessary)

<u>10</u>

Girls preferring orange juice : Boys preferring orange juice

50 : 48 (Divide by 2 on both sides)

25 : 24

<u>11</u>

Boys preferring orange juice : Boys preferring grapefruit juice

48 : 10 (Divide by 2 on both sides)

24 : 5

Remember :

  • <u>1 week = 7 days</u>
  • <u>1 hour = 60 minutes</u>

<u />

<u>12</u>

3 minutes : 25 seconds

3 × 60 : 25 (Divide by 5 on both sides)

3 × 12 : 5

36 : 5

<u>13</u>

2 weeks : 6 days

2 × 7 : 6 (Divide by 2 on both sides)

7 : 3

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 45.0 and 55.
ra1l [238]

Answer:

0.025

Step-by-step explanation:

Hello!

Given that the classes are uniformly distributed between 45.0 and 55.0 minutes, the propability distribution will be:

P(x)=\frac{1}{55-45} = \frac{1}{10}

Now, we are looking for a probability P(51.5<x<51.75) which can be computed as:

P(51.5

Therefore:

P(51.5<x<51.75) = 0.025

or

P(51.5<x<51.75) = 2.5%

<em><u>I strongly believe that the answer for both questions have the same answer, I believe this because there is no additional info for a given class  or selecting a class. I think both probabilities are the same.</u></em>

A sector of a circle of radius 80 mi has an area of 1600 mi2. Find the central angle (in radians) of the sector.
Butoxors [25]

Answer:

The central angle of the sector is 0.5 radian

Step-by-step explanation:

given;

radius of the circle, r = 80 mi

area of the sector, A = 1600 mi²

Area of sector is given by;

A = ¹/₂r²θ

where;

θ is the central angle (in radians) of the sector

\theta = \frac{2A}{r^2}\\\\\theta = \frac{2*1600}{80^2}\\\\  \theta = 0.5 \ radian

Therefore, the central angle of the sector is 0.5 radian
