Answer:
<u>Option: a</u> is correct.
Limit of the function at x=2 is: 2
Step-by-step explanation:
Clearly by looking at the graph of the function we could observe that the function f(x) is defined as:
f(x)= -x+4 when x≠4
and 8 when x=2
since we could see that the function f(x) is a line segment that passes through the point (4,0) and (0,4).
and the equation of line passing through two points (a,b) and (c,d) is given by:
Here a,b)=(4,0) and (c,d)=(0,4)
Hence,
the equation of line is:
Now the left hand limit of the function at x=2 is:
Similarly the right hand limit of the function at x=2 is:
Hence, the limit of the function at x=2 is:
2
The quotient is 18.5, so that means it is between 17 and 20
In this case, the answer is very simple.
A term is a part not separated by the signs + or - .
In this expression, we have 3 terms.
The answer is: false.
Answer:
-18.8
Step-by-step explanation:
1/4 as a decimal is 0.25 so then if you divide -4.7 by 0.25 the answer is -18.8 :)
I hope this helped :)
Answer:
Probability that a randomly selected woman's gestation period will be between 261 and 279 days is 0.68.
Step-by-step explanation:
We are given that the average human gestation period is 270 days with a standard deviation of 9 days. The period is normally distributed.
Firstly, Let X = women's gestation period
The z score probability distribution for is given by;
Z = 
~ N(0,1)
where, 
= average gestation period = 270 days
= standard deviation = 9 days
Probability that a randomly selected woman's gestation period will be between 261 and 279 days is given by = P(261 < X < 279) = P(X < 279) - P(X 
261)
P(X < 279) = P( < 
) = P(Z < 1) = 0.84134
P(X 261) = P( 
) = P(Z -1) = 1 - P(Z < 1)
= 1 - 0.84134 = 0.15866
<em>Therefore, P(261 < X < 279) = 0.84134 - 0.15866 = 0.68</em>
Hence, probability that a randomly selected woman's gestation period will be between 261 and 279 days is 0.68.
