Answer:
1.1264
Step-by-step explanation:
Given : An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug.
To Find: If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?
Solution:
n = 35
Confidence interval = 95%. So, z =1.96
Margin of error = 
Margin of error = 
Margin of error = 
Hence the margin of error of the sample mean is 1.1264.
Answer:
y = 3
Step-by-step explanation:
We need to solve the below proportion in this problem,
First of all, we cross multiply both sides such that,
Dividing both sides by 18.
For the above proportion, we find that the value of y is equal to 3.

With these types of probe lens with no coefficient for x, all you have to do is find two number that multiply to be 12, and those same two numbers must add to be 7.
Answer: (x+3)(x+4) because 3 and 4 multiply to be 12 as well as add to be 7.
For all points that lie on the y-axis, the x-coordinate is zero.
