Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically evaluated as
=>
=>
The 95% confidence interval is mathematically represented as
substituting values
Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Answer:
The answer is D
Step-by-step explanation:
because if you do the methoes method you know that it rules out 1 and 2 and 3 after you do that its just between C and D, for the caunususicon it has to be D, that is why i think its D. hope this helps
Basically it’s like 40x10 and then let’s say your exponent is two so you would do that equation twice so it would be 800
Answer:
2H+2K
Step-by-step explanation:
because you multiply both the variables by two but you cant add them because they have diffrent letters or varibles
