Answer: (3.3, 3.5)
Step-by-step explanation:
The formula to calculate the confidence interval is given by :-
, where 
= sample mean.
z* = critical value.
= Population standard deviation.
n= Sample size.
As per given , we have
n= 217
By using z-table , the critical value for 95% confidence level : z* = 1.96
Now, the 95% confidence interval for the mean consumption of meat among males over age 50 will be :
Hence, the 95% confidence interval for the mean consumption of meat among males over age 50 =(3.3, 3.5)
<span>The answer is one. First, these are both straight lines, meaning they will have one intersection point. In order to find the intersections of these two lines, we must set them equal to one another. So x + 5y = 6 equals 3x + 30y = 36. When you solve the two equations together, you'll get one intersection point at (0 , 1.2).</span>
Answer:
Step-by-step explanation:
(-1,5)....x1 = -1 and y1 = 5
(-5,-5)..x2 = -5 and y2 = -5
slope = (y2 - y1) / (x2 - x1)
slope = (-5 - 5) / (-5 - (-1) = -10 / (-5 + 1) = -10/-4 = 5/2 <===
The ratio 4/5 can also be written as (D.4:5)
Answer:
Yes
Step-by-step explanation:
In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set. Typical examples are functions from integers to integers, or from the real numbers to real numbers.
