Answer:
-4e - 9
Step-by-step explanation:
This requires combining like terms, which means that you combine the same types of values. In this one there are two "types" of values: something that involves the variable e and just normal numbers. Let's say that the "e"s are oranges and the regular numbers are apples. Remember, you can't simply add oranges and apples together
let's start with apples (the regular numbers)
you have -19 (just pretend the minus sign is attached to the value following)
and +10
so -19+10 is -9
we have -9 apples
so now let's look at oranges, represented by e
you have 3e and -7e
if one e is one orange, then you could say that there are 3 oranges and -7 oranges
so if you subtract you get -4e, or -4 oranges
now let's add that back together with the apples, remembering that you can't actually combine them
so it would be -4e - 9
(-4 oranges and -9 apples)
The interquartile range is 24.5
the variability is 69
Answer:
= .0000001
Step-by-step explanation:
The odds of getting 1 number of out the 10 possible number (0-9) equal 10 is 1/10
There are 7 numbers to pick
P(xxx-xxxx) = 1/10 * 1/10 *1/10 * 1/10 * 1/10 * 1/10 *1/10
= .0000001
1/620 is the simplest form of 2/1240
all you had to do was simplify
2 divided by 2=1
1240 divided by 2=620 <span />
