Answer:

6

Step-by-step explanation:

Let the missing side be represented as x.

Applying the triangle proportionality theorem, we have:

\frac{15}{x} = \frac{14 - 4}{4}

Solve for x

\frac{15}{x} = \frac{10}{4}

Cross multiply

x(10) = 4(15)

10x = 60

Divide both sides by 10

x = 6

A small grocery store had 10 cartons of milk, 2 of which were sour. If you are going to buy the 6th carton of milk sold that day
andre [41]

Answer:

The probability that the sixth customer buys sour milk is \frac{1}{5}.

Step-by-step explanation:

The grocery store has a total of 10 cartons of milk.

The number of cartons of milk that are sour is, 2.

  • If none of the sour cartons of milk were bought by the first 5 buyers, then the probability of this event is:

       P (Both the sour cartons are available to be sold to the sixth customer)

        = P(2\ sour\ cartons)=\frac{2}{5}

  • If only one sour carton of milk is sold to the first 5 buyers then the probability is:

        P (Only one sour cartons is available to be sold to the sixth customer)

            = P(1\ sour\ cartons)=\frac{1}{5}

  • If both the sour carton of milk is sold to the first 5 buyers then the probability is:

        P (None of the sour cartons is available to be sold to the sixth customer)

         = P(0\ sour\ cartons)=\frac{0}{5}

Compute the probability that the sixth customer buys sour milk:

= P (Both sour milk is available for the 6th customer) +  

      P (Only one sour milk is available for the 6th customer) +  

          P (None of the sour milk is available for the 6th customer)

=\frac{{8\choose 5}{2\choose 0}}{{10\choose 5}} \times\frac{2}{5} +\frac{{8\choose 4}{2\choose 1}}{{10\choose 5}} \times\frac{1}{5} +\frac{{8\choose 3}{2\choose 2}}{{10\choose 5}} \times\frac{0}{5} \\=\frac{56\times2}{252\times5} +\frac{140\times1}{252\times5} +0\\=\frac{1}{5}

Thus, the probability that the sixth customer buys sour milk is \frac{1}{5}.

Usimov [2.4K]
If you meant 1,700,000, it'd be 170,000 because you multiply it by 0.1. If you meant 17,000, you'd get 1,700.

The silver bar is 15cm long. The bar is melted and the silver is then made into a cuboid. The base of the cuboid is 10cm by 10 c
marishachu [46]
The question is impossible to answer since. Since you can't answer that without knowing the volume of the bar to start with. The only given is the length, there should be other dimensions like the width and area of the cross-section, for instance. 
Volume = Width x Depth x Height in all cases, so when you know the volume. But to solve for the height of the cuboid, the equation is V/100 (because the base of the cuboid is 100 cm^2)
