Rate of Change between August and October

Mathematics
2 answers:
nikdorinn [45]4 years ago

Answer:

15 students per month

Step-by-step explanation:

The rate of change is calculated as

\frac{f(b)-f(a)}{b-a}

f(b) = 95 ← number of students in October

f(a) = 65 ← number of students in August

b - a = 2 ← difference in months

Thus

rate of change = \frac{95-65}{2} = \frac{30}{2} = 15

The rate of change is the ratio between the change in the y and x coordinates. The students ranged from 65 to 95 in two months, so the rate is

\dfrac{95-65}{2}=\dfrac{30}{2}=15

For a data consisting of 9 observations, the sum of 9 values is 360 and the sum of squares of deviation taken from the mean is 2
maxonik [38]

Answer:

4 ; 32

Step-by-step explanation:

Given that :

Number of observations, n = 9

Let observations = X

ΣX = 360

The mean, (m) is calculated using the formula :

m = ΣX / n

m = 360 / 9

m = 4

Σ(X - m) = 288 (sum of square of deviation )

Variance is calculated using the formula :

[Σ(X - m) / n]

Variance = Sqrt(288 / 9)

Variance = 32

What is .9 repeating as a fraction
Finger [1]

There is no answer to this because:

Any digit repeating like that would usually be ?/9

Example: 0.1 repeating = 1/9

                0.2 repeating = 2/9

                0.8 repeating = 8/9

But 0.9 repeating? There should not be a fraction for that.

If you want to round up to 1, you can.

Polonium-210 is a radioactive substance with a half life of 138 days. If a nuclear facility is handling 265 grams of polonium-21
dlinn [17]

The half life is 138 days, meaning exactly half of the material will decay after this time. Use this information to find the decay factor k:

\dfrac12=e^{138k}\implies k=-\dfrac{\ln2}{138}

Then after 250 days, there will be

265e^{250k}\approx75.492

grams left.
