Answer:
value we use for z value of sample test is r/n
Step-by-step explanation:
Given data
proportion p
trials = n
successes = r
to find out
what value we use for z value of sample test
solution
here
we know that
Probability of a success in single trail test = Number of successes/Number of trails
Probability of a success in single trail = r / n
so that
value we use for z value of sample test is r / n
Answer:
Step-by-step explanation:
Given XZ with X(-4,3) and Z(6.-2), find the coordinates of Y if Y divides XZ one-fifth of the way from X to Z.
Since slope of line passing through two points
We now find the slope of the line passing through the points (2,3) and (4,6) as shown below:
m=
4−2
6−3
= 23
Therefore, the slope of the line is 23 .
Now use the slope and point (2,3) to find the y - intercept.
y=mx+b
⇒3=( 23 ×2)+b
⇒3=3+b
⇒b=3−3=0
Write the equation in slope intercept form as:
y=mx+b
⇒y= mx+b
⇒y= (-2)x − 13
Hence, the equation of the line is y= 23
x..
Answer:
50 paise coin = 9
25 paise coin = 18
Step-by-step explanation:
Let :
Number of fifty paise = x
Number of 25 paise = y
50x + 25y = 900 - - - (1)
y = 2x - - - (2)
50x + 25(2x) = 900
50x + 50x = 900
100x = 900
x = 900/100
x = 9
y = 2x
y = 2(9)
y = 18
