Answer: 0.064
Step-by-step explanation:
The formula to find the margin of error :-
Given : Significance level : 
Critical value : 
Sample size : n=400
The proportion of people support the candidate :p=0.44
Then , 
Hence, Margin of error = 0.064
4x+9=3(x-2)+10
4x+9=3x+4
x+9=4
x=-5
The answer is 1 or A)-5
It's false. It's a product so...
Derivative of the first TIMES the second PLUS derivative of second TIMES the first.
Derivative of the first (x^3) = 3x^2
Times the second = 3x^2 * e^x
Derivative of the second = e^x (remains unchanged)
Times the first = e^x * x^3
So the answer would be (3x^2)(e^x) + (e^x)(x^3)
which can be factorised to form x^2·e^x(3 + x)
Answer:
a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm.
Step-by-step explanation:
so I'd say 21
Good question I’m having trouble with this but I hope someone understands this
