Answer:
The answer is 10.5
Step-by-step explanation:
Answer:
x ∈ (-∞, -2) ∪ (2, ∞)
Step-by-step explanation:
To solve this problem we must factor the expression that is shown in the denominator of the inequality.
So, we have:
So the roots are:
Therefore we can write the expression in the following way:
Now the expression is as follows:
Now we use the study of signs to solve this inequality.
We have 3 roots for the polynomials that compose the expression:
.
Observe the attached image.
We know that the first two roots are not allowed because they make zero the denominator, we also know that (x + 5) ^ 2 is always positive because it is squared, so it is not necessary to include the numerator in the study of signs.
Note that:
when
when
Finally after the study of signs we can reach the conclusion that:
x ∈ (-∞, -2) ∪ (2, ∞)
No, because an acute triangle has 3 acute angles, and a right triangle has a 90 degree angle. hope this helps (;
We know that the Mean ( or the average ) is 7.7 lbs.The standard deviation : SD = 0.5 lbs.7.7 - 2 * 0.5 = 7.7 - 1 = 6.7 lbsIt means that 6.7 lbs is The Mean - 2 Standard deviations.According to the bell - shaped curve of Normal distribution:50 % + 34 % + 13.5 % = 97.5 %Answer: 97.5 % of babies would be at least 6.7 lbs.
