Mathematics
1 answer:
irinina [24]2 years ago
4 0

Answer:

Answer:

1/9

Step-by-step explanation:

4 people use all three facilities, then

16 - 4 = 12 people use the gym and the track and do not use the pool;

9 - 4 = 5 people use the pool and the track and do not use the gym;

19 - 4 = 15 people use the gym and the pool and do not use the track.

At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36=1/9

in a triangle two sides of the same length the ratio of each of these sides to the third side is 5:3 if the perimeter of the tri
AveGali [126]

Answer:

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

           P = s1 + s2 + s3                 side 1 = side 2 =  x

                                                     x/side 3 = 5 / 3

                                                     x  = (5/3) side 3

                                                     x (3/5)  = side 3

                                                 

                                                     perimeter = 65    slove for x

          65  = x + x + 3x/5

         325  = 5x + 5x + 3x

         325  = 13X

          25   = x    equal side 1 and side 2  

          side 3 = 25(3/5)  = 15

Help Please. I'm no good when it comes to math
Natali [406]

Answer: question 5 is C

Question 4 is 37.68

Question 3 is 153.86 ft sq

The question about finding the area with a diameter of 16mm is 803.84

The next one is A. 25÷8

Step-by-step explanation:

C = 2 pi r

C = 2 pi (7.8) and you get 49.01

Becuse the question is asking to round c is the best choice

When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6

The formula for this one is A = pi r sq

You have the radius for this one is 7

Put 7 into that and you get. ~153.94

What is the median of this data set?
bazaltina [42]

Answer:

14

Step-by-step explanation:

Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.

and for extra just in case.

Mean=16.222

the mean= the average of the data set

Mode is 13,14

The mode is the number that appears the most in a data set and 13 and 14 appear twice.

Your range is=13

Range is the highest number subtracting the lowest number so 24 -11 which =13

Minimum is 11 because the minimum is the lowest number in data set..

Maximum is 24

Maximum is the highest number in the data set.


I hope this helps have a awesome day:)

Find the distance (-4,5) and (7,18)
seropon [69]

Answer:

\sqrt{290}\ units

Step-by-step explanation:

The distance between points (x_1,y_1) and (x_2,y_2) is

\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

Hence, the distance between points (-4,5) and (7,18) is

\sqrt{(-4-7)^2+(5-18)^2}\\ \\=\sqrt{(-11)^2+(-13)^2}\\ \\=\sqrt{121+169}\\ \\=\sqrt{290}\ units
