Answer:

3/20

Step-by-step explanation:

The total number of marbles is

3 red marbles+ 2 blue marbles+ 5 green marbles = 10 marbles

P(1st marble is red) = red marbles/total

                                =3/10

We replace the marble so there are still 10 marbles in the bag

P(2nd marble is green) = green marbles/total

                                =5/10 = 1/2

P(1st red, 2nd green) = P(1st marble is red) * P(2nd marble is green)

                                   =3/10 *1/2

                                    =3/20

One card is randomly selected from a deck of cards find the odds against drawing a seven
Stella [2.4K]

Answer:

\frac{3}{4}

Step-by-step explanation:

Probability of getting a 7 + Probability of not getting a 7 = 1.

Odds against drawing a 7 = Probability of not getting a 7.

We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.

There a four sevens in a deck of card, one of each kind.

Probability of getting a 7 = $ P(7) = \frac{4}{52} = \frac{1}{13} $

$ \implies P(not \hspace{1mm} getting \hspace{1mm} a \hspace{1mm} 7) = 1 - P(7) $

$ \implies $ P(not getting a 7) $ = 1 - \frac{1}{13} = \frac{12}{13} $

Will someone help me on this problem
ASHA 777 [7]
1 week = 7 days
1 gallon = 16 cups ⇒ 1 cup = 1/16 gallon

1.5  cups = 1.5 · 1/16 gallon = 15 · 1/160 gallon = 3/32 gallon

1.5 cups per day = 3/32 gallons per day = 7 · 3/32 gallons per week
= 21/32 gallons per week

Which series of transformations shows that rectangle A is similar to rectangle B?
Brut [27]

Answer:

D. Dilate rectangle A by a scale factor of 3 with the center of dilation at the origin and rotate it 90° clockwise about the origin.

Step-by-step explanation:

The coordinates of triangle A are (-2,1) , (1,1), (1,-1) and (-2, -1) while that of triangle B are (-3, 6), (3, 6), (3, -3) and (-3, 3).

To transform A to be we need a combination of two transformations, and that is dilation and rotation.

If A is dilated by a scale factor three through the origin as the center of dilation and then rotated through 90° clockwise with the origin as the center of origin, then rectangle B will be obtained.
