Hope this helps! This is the long division way.
Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.
The formula for probability of getting an event is given by :
Here, favourable outcome = 1
Total outcomes = 8
So,
So, the correct option is (b).
1-(-18)= 19
sense the subtract and negative cancel out, look at it as a plus sign between 1 and 18 so 1+18=19
+
Convert your denominators into a same number..
as a mixed number =
Your answer -
Answer:
24.6 years
Step-by-step explanation:
Given
Given
μ=32 years
σ=6.2 years
and
z-score= -1.2
Since we are given the values of mean, standard deviation and z-score of a value, we have to find the value.
We will use the formula of calculating z-score for finding the value.
Let x be the value that we have to find out
z-score= (x-μ)/σ
-1.2=(x-32)/6.2
-1.2*6.2=x-32
-7.44=x-32
x= -7.44+32
x=24.56
Rounding off to the nearest 10th
x=24.6 years
So the age of movie attendant with a z-score of -1.2 is 24.6 years ..
