Answer with explanation:

→Suppose ,y= mx +c, is a linear equation and the line passes through two points ,(x_{1},y_{1}),(x_{2},y_{2}).

→Slope of line joining two points having coordinates ,(x_{1},y_{1}),(x_{2},y_{2}) can be obtained by the formula

 m=\frac{\text{Difference of y coordinates}}{\text{Difference of x coordinates}}\\\\m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Answer and Step-by-step explanation:

Each unit is equal to each other, and we know that both allowances together equates to 72, so if we divide the amount of units that there are, we can determine the amount per month.

There are 8 units in total.

72 divided by 8 = 9

<u>Now, we do 9 times the amount each person has.</u>

<u>You = 5 * 9 = 45</u>

<u>Friend = 3 * 9 = 27</u>

At the movie theatre, child admission is $5.20 and adult admission is $8.60. On Sunday, 132 tickets were sold for a total sales
xxMikexx [17]

Answer:

60 tickets for children were sold

Step-by-step explanation:

Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.

x + y = 132   (i) Because 132 tickets were sold in total

5.20x + 8.60y = 931.20   (ii)   because the total of $ obtained by sales was 931.20.

We must clear x. Then we substitute (i) in (ii)

5.20x +8.60(132-x) = 931.20

5.20x + 1135.2 - 8.60x = 931.20

-3.4x = -204

x = 60

Let V be the event that a computer contains a virus, and let W be the event that a computer contains a worm. Suppose P(V) = 0.17
ArbitrLikvidat [17]

Answer: 0.82

Step-by-step explanation:

The probability of the computer not containing neither a virus nor a worm is expressed as P(V^{C}∩W^{C}) , where P(V^{C}) is the probability that the event V doesn't happen and P(W^{C}) is the probability that the event W doesn't happen.

P(V^{C})= 1-P(V) = 1-0.17 = 0.83

P(W^{C})=1-P(W) = 1-0.05 = 0.95

Since V^{C} and W^{C} aren't mutually exclusive events, then:

P(V^{C}∪W^{C}) = P(V^{C}) + P(W^{C}) - P(V^{C}∩W^{C})

Isolating the probability that interests us:

P(V^{C}∩W^{C})= P(V^{C}) + P(W^{C}) - P(V^{C}∪W^{C})

Where P(V^{C}∪W^{C}) = 1 - 0.04 = 0.96

Finally:

P(V^{C}∩W^{C}) = 0.83 + 0.95 - 0.96 = 0.82
