12. In Europe, 88% of all households have a TV. 51% of all households have a TV and VCR. What is the probability that a household has a VCR given they have a TV?

Answers

Answer 1

Answer:

Using conditional probability, it is found that there is a 0.5795 = 57.95% probability that a household has a VCR given they have a TV.

Conditional Probability

$P(B|A) = (P(A \cap B))/(P(A))$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem:

Event A: Household has a TV.

Event B: Household has a VCR.

88% of all households have a TV, hence $P(A) = 0.88$ .

51% of all households have a TV and VCR, hence $P(A \cap B) = 0.51$ .

Hence, the conditional probability is:

$P(B|A) = (P(A \cap B))/(P(A)) = (0.51)/(0.88) = 0.5795$

0.5795 = 57.95% probability that a household has a VCR given they have a TV.

Answer 2

Answer:

Answer:

0.579 is the probability that a household has a VCR given they have a TV.

Step-by-step explanation:

We are given the following in the question:

Probability of all households have a TV = 88% = 0.88

$P(T) = 0.88$

Probability of all households have a TV and VCR = 51% = 0.51

$P(T\cap V) = 0.51$

We have to find the probability that a household has a VCR given they have a TV.

The conditional probability is given by:

$P(V|T) = \displaystyle(P(V\cap T))/(P(t)) = (0.51)/(0.88) = 0.579$

0.579 is the probability that a household has a VCR given they have a TV.

Answer:

c. 9i.

Step-by-step explanation:

$√(-81)$

= $√(-1 * 9 * 9)$

= $√(-1 * 9^2)$

= $9√(-1)$

The square root of -1 is the same thing as i.

= $9i$

So, your answer is C.

As a promotional offer, a new gym is offering a 30% discount to those who sign up in the first month. Patty and her 2 siblings take advantage of the offer and sign up for a total amount of €210. What were the total savings mode? Work out the average savings per person

Answers

Answer:

$Total\ Savings = 63$

$Average\ Savings = 21$

Step-by-step explanation:

Given

$Amount = 210$

$Savings = 30\%$

Solving (a) Total Savings Mode

$Total\ Savings = Savings * Amount$

$Total\ Savings = 30\% * 210$

$Total\ Savings = 63$

Solving (b): Savings per person

Since, there are 3 individuals involved;

$Average\ Savings = (Total\ Savings)/(3)$

$Average\ Savings = (63)/(3)$

$Average\ Savings = 21$

Answer:

a = €90

b = £30

Step-by-step explanation:

They had a discount of 30% means that they paid 70%.

100% (total percentage ) - 30%( discounted for them) = 70% ( meaning they paid for 70% instead of 100%).

To find the total saving made, we need to know the total cost without the promo and substract from the 70% payment made.

70% payment made = €210.

1% = [210/70 = €3].

if 1% = €3, then 100% willl be €300.

100% the gym offers = €300.

Total saving made = total cost the gym offers - the 70% payment made.

€300 - €210 = €90.

If you want to be sure. 30% of €300 = 90.

meaning that they had a discount of €90.

If they paid €210 + €90 = €300.

b) The avearge saving per person?

Remember the question said Patty and 2 siblings, suggest they are 3 people in the picture.

If the 3 saved €90,

averge of one person:

90/3 = €30

Suppose that a digitized TV picture is to be transmitted from a source that uses a matrix of 480 * 500 picture elements (pixels), where each pixel can take on one of 32 intensity values. Assume that 30 pictures are sent per second. (This digital source is roughly equivalent to broadcast TV standards that have been adopted.) Find the source rate R (bps).

Answers

Answer:

36,000,000 bps

Step-by-step explanation:

Matrix of 480 by 500 = 480 X 500 = 240,000 pixels

Intensity values per pixel = 32. This simply means the color variations in this TV.

The bit per pixel for an intensity value of 32 is 5 (That's 2 raised to the power of 5)

Pictures sent per second = 30

Source rate R (bps) = Total number of pixels in the matrix X bit per pixel X Number of pictures sent per second.

Source rate R (bps) = 240,000 X 5 X 30 = 36,000,000 bps

Final answer:

The source rate for the digitized TV picture is 230,400,000 bps.

Explanation:

The source rate can be calculated by multiplying the number of pixels per picture element by the number of intensity values per pixel and by the number of pictures sent per second.

So, the source rate R (bps) is given by:

R = (480 * 500) * 32 * 30

Calculating this, we find that the source rate is 230,400,000 bps.

P divided by 8.2 = 9.3
who is smart

Answers

The value of p is 76.26 is the equation p divided by 8.2 = 9.3

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

p divided by 8.2 = 9.3

A division is a process of splitting a specific amount into equal parts.

We have to find the value of p.

p/8.2 = 9.3

p divided by eight point two equal to nine point three

Apply cross multiplication

p=9.3×8.2

p=76.26

Hence, the value of p is 76.26 is the equation p divided by 8.2 = 9.3

Answer:

$(P)/(8.2\n)=9.3\n\nP=9.3 x 8.2 \n\nP= 76.26$

Step-by-step explanition

In algebra the divide sign is not usually used, so we put a fraction line instead.
After that, we take 8.2 to the right hand side in order to find the value of "P". Since it was divided on the left-hand side, we turn the sign into a multiply, as we moved it on the other side of the equal sign.
The last step is to solve it, multiply the 2 numbers and you hve your answer.
