Answer:
(0.4,1)
Step-by-step explanation:
I hope that this is for homework and not a quiz or test.
Since we already know the value of y which is 1, we can substitute it into the equation above it.
-5x+3=1
-5x=-2
x=2/5=0.4
So in (x,y) format (0.4,1)
Answer:
( 2x - 3 ) / 5
Step-by-step explanation:
2x - 6 = 5y - 3
2x - 6 + 3 = 5y
2x - 3 = 5y
y = ( 2x - 3 ) / 5
a is the beggining number and n is the amount of times needed to do this. if is 17 you would need to subtract 7 from the originol number 12 (a) that many times.
Answer:
0.13591.
Step-by-step explanation:
We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.
We know that z-score tells us that a data point is how many standard deviation above or below mean.
To solve our given problem, we need to find area between z-score of -2 and -1 that is
.
We will use formula
to solve our given problem.

Using normal distribution table, we will get:


Therefore, the probability of randomly selecting a score between 1 and 2 standard deviations below the mean would be 0.13591.
