Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

= $\frac{9}{12} years$

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

$Interest = Principal \times Rate \times time$

$116.25=1550 \times r \times \frac{9}{12}$

$r= \frac{116.25 \times 12}{1550 \times 9}$

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

A countries population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponentia

scoundrel [369]

Answer:

The population in 2017 is 171 million

Step-by-step explanation:

Let's assume population starts from 1991

so,

initial population is 147 million

so, $A=147$

we can use formula

$P=Ae^{kt}$

we can plug A=147

$P=147e^{kt}$

In 1998:

t=1998-1991=7

$P=153$

now, we can plug these values into formula and find k

$153=147e^{7k}$

Divide both sides by 147

$\frac{147e^{7k}}{147}=\frac{153}{147}$

$e^{7k}=\frac{51}{49}$

$\ln \left(e^{7k}\right)=\ln \left(\frac{51}{49}\right)$

$k=\frac{\ln \left(\frac{51}{49}\right)}{7}$

$k=0.00572$

now, we can plug it back

and we get

$P=147e^{0.00572t}$

In 2017:

t=2017-1991=26

we can plug it and find P

$P=147e^{0.00572\times 26}$

$P=170.57$

So,

The population in 2017 is 171 million

A chance event with probability 1 is certain to happen.

motikmotik

Answer:

True, for Probability of a chance event certain to happen is 1.

Step-by-step explanation:

Given that,

A chance of event with probability of happening certainly is 1.

To find:- Is it true or false?

from the given scenario,

Probability states that P(Event) is a number describing the chance of that event will happen And value of $P(E)$ lies between $0\leq P(E)\leq 1$ ..

$P(An Event) =$ $\frac{Number of favourable outcomes}{Total number of outcomes}$

When An Event is certain to occur then its $P(E) = 1$ .

when An Event cannot possible to occur then its $P(E) = 0$ .

And

Is there any chance that event will occur then its value lies $0\leq P(E)\leq 1$ .

Let us take an Example:-

If it is Saturday, then the probability that tomorrow is Sunday is certain, therefore the probability is 1.
The probability that tomorrow is Friday if today is Sunday is 0.

Hence,

True, for Probability of a chance event certain to happen is 1.
