Answer:
z=-2.09
Step-by-step explanation:
Given that a study of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only 41% of the time.
Set up hypotheses as:
(left tailed test at 5% significance level)
Standard error = 0.043
Sample proportion p = 0.41
p difference = 
Test statistic Z = p diff/std error
= 
Z = -2.09
Hi there!
To find your answer, simply sub in the point and the slope into y-y1=m(x-x1) for y1, x1 and m!
m=-8
point: (1,-8) use this point for x1 and y1
y+8=-8(x-1)
Therefore your equation is y+8=-8(x-1)
Hope this helps!
Solution :
Given
Let the initial approximation is 
So by Newton's method, we get
are identical up to eight decimal places.
The approximate real root is x ≈ 1.32471795
∴ x = 1.32471795
A 16 karat gold means that there are 16 parts of gold in
24 parts of the gold chain. Therefore the weight of the pure gold is:
pure gold = (16 / 24) * 2.6 ounces
<span>pure gold = 1.73 ounces</span>
