Answer:
A rational number.
Step-by-step explanation
A rational number is a ratio of whole numbers.
1/3 is the ratio of 1:3
3:1 becomes 3/1 = 3
32:10 can be written 32/10 or 16/5 or 3.2
16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.
Therefore, 3.2 which can be expressed as 16/5 is a rational number.
Answer:
True
Step-by-step explanation:
A six sigma level has a lower and upper specification limits between
and
. It means that the probability of finding no defects in a process is, considering 12 significant figures, for values symmetrically covered for standard deviations from the mean of a normal distribution:

For those with defects <em>operating at a 6 sigma level, </em>the probability is:

Similarly, for finding <em>no defects</em> in a 5 sigma level, we have:
.
The probability of defects is:

Well, the defects present in a six sigma level and a five sigma level are, respectively:
Then, comparing both fractions, we can confirm that a <em>6 sigma level is markedly different when it comes to the number of defects present:</em>
[1]
[2]
Comparing [1] and [2], a six sigma process has <em>2 defects per billion</em> opportunities, whereas a five sigma process has <em>600 defects per billion</em> opportunities.
Answer:
Therefore the population will be maximum when x=30 inches.
Step-by-step explanation:
Given that, the mosquito population is a function of rainfall and can be approximated by the formula

where x is the number of inches of rainfall.

Differentiating with respect to x

Again differentiating with respect to x

Now we set N'(x)=0





Since at x=30, N''(x)<0, So at x=30, N(x) has maximum value.
Therefore the population will be maximum when x=30 inches.
Answer:
The expense of the visit to dental specialist is equivalent to (50+100n)
Step-by-step explanation:
If one eighth of the pizza falls, that leaves seven eights of the pizza to be shared:

If the 7/8 pizza is shared between three people, then you have to divide 7/8 by 3. We know that dividing a fraction by 3 is the same as multiplying by 1/3:

Therefore, each person gets 7/24 of the whole pizza.
