Answer:

Therefore the third option is the name of radius i.e

$\overline{AC}$

Step-by-step explanation:

Given:

Circle A i.e A is the center of a Circle.

Radius :

The radius of a circle is the distance from the center of the circle to any point on its circumference.

A is the center of a Circle.

Therefore,

Distance From A to B i.e AB =Radius

Distance From A to C i.e AC =Radius

Distance From A to D i.e AD =Radius

Therefore the third option is the name of radius i.e

$\overline{AC}=Radius$

Also,

$\overline{BD}=Chord$

$\overline{BC}=Diameter$

$\overline{CD}=Chord$

What is 12.95p=44 simplified to its lowest value

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

What is 12.95p=44 simplified to its lowest value?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf \: 12.95p = 44$

Divide both sides by 12.95.

$\sf \: p=\frac{44}{12.95} \\$

Expand 44/12.95 by multiplying both the numerator and denominator by 100.

$\sf \: p=\frac{4400}{1295} \\$

Reduce the fraction 4400/1295 to its lowest terms by extracting and cancelling out 5.

$\boxed{ \boxed{ \bf p = \frac{880}{259} = 3\frac{103}{259} \approx 3.39}}$

Jim had 360 stamps he sold 1/3 of them on Monday and 1/4 of the remainder on Tuesday how many stamps did he sell on Tuesday

denis-greek [22]

Answer:

Step-by-step explanation:

Since Jim sold 1/3 of his stamps on Monday, the remainder would be 2/3 of his total stamps.

Divide 360 stamps by 3. Minus the stamps sold on Monday from 360 to get the remainder.

stamps sold on Monday = 360 ÷ 3 = 120

remainder = 360 - 120 = 240

He sold 1/4 of the remainder on Tuesday.

Divide the remainder by 4.

stamps sold on Tuesday = 240 ÷ 4 = 60

He sold 60 stamps on Tuesday.

The on-line access computer service industry is growing at an extraordinary rate. Current estimates suggest that only 20% of the

vitfil [10]

Answer:

The probability is 0.4207

Step-by-step explanation:

The probability of a home-based computer having access to on-line services is p = 0.2 (data from the exercise)

Then, the probability of a home-based computer not having access to on-line services is p = 1 - 0.2 = 0.8

We are going to use this probability (p = 0.8) to solve the exercise.

Let's define the random variable X

X : ''Number of home-based computers not having access to on-line services''

X can be modeled as a binomial random variable

X ~ Bi(p,n)

X ~Bi(0.8,25)

Where p is the success probability and n is the number of Bernoulli independent experiments we are taking place.

We are going to count ''a success'' as a computer not having access to on-line services.

The binomial probability function is :

$P(X=x)=(nCx)p^{x}(1-p)^{n-x}$

Where P(X=x) is the probability of the random variable X to assume the value x

nCx is the combinatorial number define as

$nCx=\frac{n!}{x!(n-x)!}$

p is the success probability and n the number of Bernoulli independent experiments taking place.

In our exercise,

$p=0.8\\n=25$

We are looking for :

$P(X>20)=P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)$

$P(X>20)=(25C21)0.8^{21}0.2^{4}+(25C22)0.8^{22}0.2^{3}+(25C23)0.8^{23}0.2^{2}+(25C24)0.8^{24}0.2^{1}+(25C25)0.8^{25}0.2^{0}$

$P(X>20)=0.1867+0.1358+0.0708+0.0236+0.8^{25}$

$P(X>20)=0.4207$

Finally, the probability of finding that more than 20 of 25 home-based computers do not have access to on-line services is 0.4207
