Sam is planting a garden that measures
nikitadnepr [17]

Answer:

63.7 feet

Step-by-step explanation:

We can re-write the width and the length both as rational numbers:

- Width: w=6.5=\frac{65}{10}

- Length: L=9.8=\frac{98}{10}

So now we can find the area of the garden by multiplying width and length:

A=wL=\frac{65}{10}\cdot \frac{98}{10}=\frac{65\cdot 98}{10\cdot 10}=\frac{6370}{100}=63.7

You are challenged to a lucky draw game. If you draw a face card (K, Q, J) from a standard deck of cards, you earn 10 points. If
Aleksandr [31]

The Expected value of a draw from the given question is; A; 0.77

We are told the face cards are K, Q, J. This means that there are 3 face cards for each of the 4 suits.

Since you earn 10 points for each face card, it means that;

total possible gain = 10 × 3 × 4 = 120

In a deck of cards, there are a total of 52 cards.

This means that;

Number of cards that are not K, Q or J = 52 - (4 × 3) = 40

Since 2 points are lost for drawing any of this 40 cards, then;

Total possible loss = 40 × 2 = 80

Expected gain = 120 - 80

Expected gain = 40

Expected value of a draw = 40/52

Expected value of a draw = 0.77

Which relation is represented by the arrow diagram?
lorasvet [3.4K]

The relation represented by the arrow diagram is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.

Option: C.

<u>Step-by-step explanation:</u>

A function is a relation in which each input value(domain) results in one output value(range). It is represented diagrammatically using the mapping method.

It shows how each element of domain and range are paired. That is like a flowchart it shows the input values marking its corresponding output value.

In the given diagram,

The values given in the left are domain and values given in the right are range.

Thus, -3 marks to 4, then can be written as (-3,4).

Similarly,

-1 marks 5 = (-1,5).

0 marks 7= (0,7).

2 marks 2= (2,2).

5 marks 7 =(5,7).

⇒ The complete points sequence is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.
