Answer:
x > -1
Step-by-step explanation:
-10 < x - 9 add 9 to both sides of the inequation
9 + (-10) < x - 9 + 9 minus 9 will eliminate the positive 9 on the right side of the inequation therefore the answer is:
-1 < x and x > -1
Answer:
4.8
Step-by-step explanation:
Radius is 1/2 of the diameter so just do 2.4 and multiply it by 2
hope this helps :)
Answer:
y 3 4 5

P(Y) 0.1875 0.5 0.3125
Step-by-step explanation:
For this case we have the following statement : SOME DOGS ARE BROWN
And if we count the number of letters in the statement we have 16 possible letters. We can define the following random variable
Y= Length of word containing a selected letter.
For example the word DOGS have 4 of the total 16 letters, so we can define the probability using empirical approximation for each word like this:

And similar for the other words we have:



And we have the following distribution for the words in the statement with the random variable Y defined previously:
Word SOME DOGS ARE BROWN
________________________________________
y 4 4 3 5
P(Word) 0.25 0.25 0.1875 0.3125
And as we can see the possible values for Y are 3,4 and 5, so then we can define the probability distribution for Y like this:
y 3 4 5
___________________________________
P(Y) 0.1875 0.5 0.3125
The y-coordinate would be 42.
Hexagons have 6 sides. The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.
The y-coordinate is the total number of sides. 7 hexagons * 6 sides per hexagon = 42 sides.
