Answer:

D b = sqrt(c^2 -a^2)

Step-by-step explanation:

We are using the Pythagorean theorem,

a^2+b^2=c^2

We want to solve for b

Subtract a^2 from each side

a^2 -a^2+b^2=c^2-a^2

b^2 = c^2 -a^2

Take the square root of each side

sqrt(b^2) = sqrt(c^2 -a^2)

b = sqrt(c^2 -a^2)

Answer:

answer A : b=√(c-a)

Step-by-step explanation:

a²+b²=c²

subtract a² from both sides to isolate b²

b²=c²-a²

take the square root of both sides to get from what b² equals to what b equals

b=√(c-a)

If a sample of 14 students were taken from a population of 168 students, could refer to the variance of how many of the students
tensa zangetsu [6.8K]

⇒The Variance tells us spread between each variate in data set from mean.

 Now, Coming to the Question

⇒Sample of 14  students were taken from a population of 168 students.

Variance =Expected value of square of each variate taken from mean, which can be represented as

      =\sum_{N=1}^{k} \frac{E(x-\mu)^2}{N}

Size of Sample taken in terms of Percentage

                    =\frac{14}{168} \times 100\\\\=\frac{100}{12}\\\\=8.\bar{3}

⇒Sample Size is Approximately only 8.4% of total Population,which is very small, that can't represent the whole Population Variance.

Option B:→ 14 , is most appropriate, which Represents the Variance of 14 student height.

Answer:

B.  0.10 - 0.20 = 0.10.

Step-by-step explanation:

100/1000 = 0.10 of the population were born , and

200/1000 = 0.20 of the population died so it is:

0.10 - 0.20 = 0.10.
