Since we know that \text{Simple interest}=\frac{PRT}{100}, where P is principle amount, R is interest rate and T is time.

Now let us substitute our given information in simple interest formula.

\text{Simple interest}=\frac{220\cdot4\cdot6}{100}

\text{Simple interest}=\frac{5280}{100}

\text{Simple interest}=52.80

Therefore, Mary will earn $52.80 after 6 years.

There are 5 parts of a box-and-whisker plot.

Lowest Value (Minimum)= that's the left end of the graph, and shows what the minimum value is. Here, the minimum is 46.

Lower Quartile (Q₁)= This is the left edge of the "box" in a box-and-whisker plot. Here it is 55.

Median (Q₂)= This is the line in the middle of the box, and represents the very center of minimum and maximum values. Here it is 58.

Upper Quartile (Q₃)= This is the right edge of the box in a box-and-whisker plot. Here it is 63.

Highest Value (Maximum)= This is the farthest right point on your plot. Here it is 66.

Hope this helps! If you have any questions, please feel free to ask in the comments below!

Please help me I really need help

Answer:

A, C

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work
