Answer:

The exact probability = 0.0431

Step-by-step explanation:

Given: A bag contain - Caramels= 12, mints= 12, bars of dark chocolates=  14

Marilyn picks three items from the bag without replacement.

Total number of items 12+12+14=36

Now, probability = favorable outcome / total no. of outcomes

Probability of picking a mint = \frac{12}{36}=\frac{1}{3}

After picking a mint there are :

caramels=10, mints=11, bars of chocolate=14

Total items in the bag=35

Probability of picking another mint =  \frac{11}{35}

now, caramels=10, mints=10, bars of chocolate=14

Total items in the bag=34

Probability of picking a bar of dark chocolate =  \frac{14}{34}=\frac{7}{17}

The exact probability of picking the items:

=\frac{1}{3}\times\frac{11}{35}\times\frac{7}{17}

=\frac{77}{1785}

=0.0431

Therefore, the exact probability = 0.0431

10+12+14 = 36

12/36 x 11/35 x 14/34 = 11/255

First replace x and y by 3 and 4.

(3*(x)+1)/(4*(y)^2)

((3*(3))+1)/(4*((4)^2)) = (9+1)/(4*16) = 10/64 = 5/32.

5/32 is your answer.

irga5000 [103]
Since, each side of the fence should have the 1 3/4 feet wide decorative piece, the width of the fence should be subtracted by 2 pieces (1 3/4 feet)
                                 = 26.5 feet
Then, divide the remaining width by 4.5 feet and the answer is 5.88. Thus, approximately 5 pieces of the 4 1/2 feet should be installed.

Answer:

the side of a square is 45 m

Step-by-step explanation:

The computation of the side of the square field that contains the similar area as compared with rhombus is given below:

As we know that

Area of rhombus = Base × Altitude

= 81 × 25

= 2025

And, area of Square =  Side × side

2025 = side^2

side  = √2025

= 45m

Hence, the side of a square is 45 m
