Let width = x then
2x+ 2(x + 2) = 80
4x + 4 = 80
4x = 76
x = 19

so the width is 19 and the length is 21 answer

Let L represent the length of the rectangle
let W represent the width of the rectangle
the length is 2 more than the width
L = 2 + W
Let the Perimeter = P
P = 2(L + W)
substitute L = 2 + W, and P =80 in the Formula above
80 = 2( 2 + W + W)
80 = 2(2 + 2W)
80 = 4 + 4W
4W = 80 - 4
4W = 76
W = 19
L = 2 + W
L = 2 + 19
L = 21
the width is 19
the length is 21

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

Melvin Marshall bought 20 Mothers Day Muffins for Mama-Melanie, Auntie-Marlene, Grandma-Melissa, Cousin Carmela and Sister-Shami

amid [387]

Answer:

The number of Carmel muffins is 8 and the number of lemon muffins is 12.

Step-by-step explanation:

Melvin Marshall bought a total of 20 Muffins . Some were camel-glazed muffins and some were lemon. The Carmel muffins cost $3 each while the lemons cost $2.5 . The number of carmel muffins and lemon muffins can be calculated as follows

total number of muffin = 20

Let

a = number of carmel - glazed muffins

b = number of lemon muffins

a + b = 20.............(i)

The total cost

3a + 2.50b = 54................(ii)

Combine the equations

a + b = 20.............(i)

3a + 2.50b = 54................(ii)

a = 20 - b

insert the value of a in equation (ii)

3(20 - b) + 2.50b = 54

60 - 3b + 2.50b = 54

60 - 54 = 0.5b

0.5b = 6

divide both sides by 0.5

b = 6/0.5

b = 12

Insert the value of b in equation (i)

a + b = 20.............(i)

a + 12 = 20

a = 20 - 12

a = 8

The number of Carmel muffins is 8 and the number of lemon muffins is 12.
