Question:

James has 14,500g of sand in his sandbox. He brings home another 7,400g of sand from the beach to add to his sandbox. How many kilograms of sand does James have in his sandbox now?

Answer:

The quantity of sandbox James has is 21.9kg

Step-by-step explanation:

Given

Initial quantity of sandbox = 14,500 g

Additional quantity = 7,400 g

Required

Total quantity of sandbox in kg

Tp get the total quantity of sandbox, we simply add in the initial and additional quantity of sandbox together;

This is represented mathematically as follows;

Total = Initial Quantity + Additional Quantity

Total = 14,500 g + 7,400 g

Total = 21,900 g

But the question says the answer should be in kg

1000 g is equivalent to 1 kg

21,900 g will be equivalent to \frac{21,900}{1,000} kg

21,900g = \frac{21,900}{1,000} kg

21,900g = 21.9 kg

Hence, the quantity of sandbox James has is 21.9kg

julsineya [31]

Answer:

41.50

Step-by-step explanation:

you would have to minus the 26.50 and 25.00 and then you would get 1.5 so that's how much the tax is. you would still keep the zero tho bc if there is nothing after the 5 u add zero.

SVETLANKA909090 [29]

Answer:

Expected Value of $2:

Expected Value of $2:

Win, 0.3333 x $3 = $1

Plus

Loss, 0.6667 x -$2 = -$1.33

Expected value = ($0.33)

Step-by-step explanation:

Probability of a win = 2/6 = 0.3333

Probability of a loss = 4/6 = 0.6667

Expected Value of $2:

Win, 0.3333 x $3 = $1

Plus

Loss, 0.6667 x -$2 = -$1.33

Expected value = ($0.33)

The casino game player's expected value is computed by multiplying each of the possible outcomes by the likelihood (probability) of each outcome and then adding up the values.  The sum of the values is the expected value, which amounts to a loss of $0.33.

What is the value of y in the relative frequency table? Round the answer to the nearest percent.
Ulleksa [173]
Given a relative frequency table is made from data in a frequency table.

Frequency Table
               G                    H              Total
E            12                   11                23

F            14                    8                 22

Total       26                   19                45

Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.

Thus the relative frequency table of the frequency table above is given by:

Relative Frequency Table
                        G                                       H                                  Total
E         12/45 = 0.27 = 27%          11/45 = 0.24 = 24%       23/45 = 0.51 = 51%

F         14/45 = 0.31 = 31%          8/45 = 0.18 = 18%        22/45 = 0.49 = 49%

Total    26/45 = 0.58 = 58%         19/45 = 0.42 = 42%      45/45 = 1.00 = 100%

For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.

Therefore, the value of y is 27%
