20PTS Question On Pic Thx
harina [27]

Answer:

  (a)  $3800

  (b)  (a) -- April to May

Step-by-step explanation:

<h3>(a)</h3>

The least amount is found at the lowest point on the graph. That point is in May. It is on the line between 3700 and 3900, so the amount is $3800.

The least donation amount is a month is $3800.

__

<h3>(b)</h3>

The greatest month-to-month decrease is found where the line on the graph has the steepest negative slope. There are two segments with negative slope:

  • April - May (decrease of $500)
  • June - July (decrease of $100)

The decrease from April to May is by far the largest of these two decreases.

The greatest decrease occurred April to May.

Six friends attend a party. They form pairs for a game. How many different pairs are possible?
Leona [35]

Pairs, in this case, relates to a group of 2 or more. We have 6 friends. Let's call them A,B,C,D,E,F. This will allow us to make a [some sort of] combination tree:

1. ABC against DEF

2. ABD against CEF

3. ABE against CDF

4. ABF against CDE

5. ACD against BFE

6. ACE against BDF

7. ACF against BDE

8. ADE against BCF

9. ADF against BCE

10. AEF against BCD

I believe there are 12 combinations... I just can't think of the last 2 though.

Express sin UU as a fraction in simplest terms.
alukav5142 [94]

The expression of sinU as a fraction is 12/13

Find the diagram attached.

To get the fraction represented by sinU, we will use the SOH CA TOA identity.

From the diagram;

  • Hypotenuse = SU = 13
  • Opposite = ST = 12 (angle opposite to m<U)

Since sin theta = opp/hyp

SinU = ST/SU

SinU = 12/13

Hence the expression of sinU as a fraction is 12/13
