Answer:

66 cm

Step-by-step explanation:

Let's define the circumference first.

It is the boundary of any curved geometric figure specially circle.

We are given the diameter of the circle in the diagram

The diameter is:

d = 21 cm

to find the circumference, we have to find the radius of the circle first.

As radius is half of diameter

d = r/2

= 21/2

= 10.5 cm

The formula for circumference is:

$C = 2\pi r\\Putting\ the\ values\\C = 2 * \frac{22}{7}*10.5\\ C = \frac{462}{7}\\ C= 66\ cm$

The circumference is 66 cm ..

choli [55]

Answer:

The expected value is defined as:

EV = ∑xₙ*pₙ

Where xₙ represents the n-th event, and pₙ is the probability of that event.

Now, the events are:

The possible outcomes are: {2, 3, 4, 5, 6, 7, 8, 9, 10} 9 in total.

Winning $1, when the number is odd. The outcomes in this case are: {3. 5. 7. 9}

4 out of 9, then the probability is p = 4/9.

Lossing $1 when the number is even. The outcomes in this case are {2, 4, 6, 8, 10}

5 out of 9, the probability is p = 5/9.

Then the expected value is:

EV = (4/9)*$1 - (5/9)*$1 = (-1/9)*$1 = -$0.11...

<h2>Answer with explanation:</h2>

Given : A poll found that a particular group of people read an average of 15.7 books per year.

i.e. $\mu=15.7$

The pollsters are 99% confident that the result from this poll is off by fewer than 2.65 books from the actual average x.

i.e. E= 2.65

The confidence interval for population mean is given by :-

$|\mu-x|\leq E$

Hence, the required inequality involving absolute value for : $|15.7-x|\leq 2.65$

To solve this inequality for x, we have

$\ 15.7-2.65\leq x\leq15.7+2.65\\\\\Rightarrow\ 13.05\leq x\leq18.35$

Hence, the interval in which the average is likely to fall :

$13.05\leq x\leq18.35$
