The table gives the surface areas, in square kilometres, of five seas.
zlopas [31]

The table is missing, so i have attached it.

Also, the correct question is;

The surface area of the East China Sea is k times the surface area of the Baltic Sea.

Work out the value of k.

Give your answer to the nearest whole number

Answer:

k = 3

Step-by-step explanation:

From the attached table,

Surface area of east china = 1.25 × 10^(6) km²

Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²

We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.

Thus;

1.25 × 10^(6) = k × 0.422 × 10^(6)

k = 1.25/0.422

k = 2.96

Approximating to whole number gives;

k = 3

A state offers two lottery games, WinOne and PlayBall. Both games cost $2 per ticket.
uysha [10]
In this question, both tickets cost 2$ per ticket.
The answer to this question would be: $0

In WinOne scenario, you need to match a ticket that has to pick from A-J(10 possibilities) and 0-9 (10 possibilities). The chance to win would be: 1/10* 1/10= 1/100

The expected value must be:
E= chance to win * win amount - ticket price
E= 1//100*$200 - $2= $2-$2= 0

Mrs Smith is completing a mathematics problem. She knows when 6 is added to four times a number, the result is 50. What would be
Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{  } \end{gathered}

if we solve the equation we have:

\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}
