Mathematics
1 answer:
lianna [129]3 years ago
5 0

Answer:

X : ___ 0 ____ 1 _____ 2 ______ 3

P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15

Step-by-step explanation:

From the data, to produce a probability distribution for the data :

X : number of times blood is drawn ;

P(x) : probability that blood is drawn at X times

Hence, the probability distribution table for the data Given goes thus :

X : ___ 0 ____ 1 _____ 2 ______ 3

P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15

Probability that blood is drawn 0 times = 6/15

Probability that blood is drawn 1 time = 5/15

Probability that blood is drawn 2 times = 3/15

Probability that blood is drawn 3 times = 1/15

(6/15 + 5/15 + 3/15 + 1/15) = 1

Town M is 282 feet below sea level. Town R is 679 feet above sea level. How much higher, in feet is Town R than M?​
Genrish500 [490]

Given parameters:

Elevation of Town M = 282ft

Elevation of Town R = 679ft

Unknown:

How much higher is Town R than M = ?

Solution:

Town M lies below the sea level whereas Town R is above the sea level.

     Graphically:

                                    Town R   679ft

                                         ↑

                                         ↑

                                         ↑

                                         ↑

                                    ↔↔↔  Sea level

                                         ↓

                                         ↓

                                    Town M     282ft

Town R is 282ft + 679ft higher than Town M  = 961ft

Describe how to solve the inequality 3(a+5)<9
yanalaym [24]
First, let's use the distributive property on 3(a+5)

3(a + 5) = 3a + 3(5) = 3a + 15

Now, let's go back to the inequality

3(a+5) < 9

Use the distributive property

3a + 15 < 9

Subtract both sides by 15

3a < -6

Divide both sides by 3

a < -2

That's your answer.

Have an awesome day! :)
