<u>Answer:</u>

There is only 1 peak in this distribution.

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

In the distribution of exam scores (graded from 0 100)  for 86 students 38 students got an A, 28 students got a B, and 20 students got a C.

a) Since, 38 > 28 > 20 , there is only 1 peak for this distribution.

You are standing on a small fire tower 50 feet from a tree. You notice a squirrel in the tree. You measure the angle of depressi
irina [24]

Answer:

44.81 feet

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ACD

Find the length side AC (height of the small fire tower)

tan(52^o)=\frac{AC}{50} ---> by TOA (opposite side divided by the adjacent side)

Solve for AC

AC=tan(52^o){50}

AC=64\ ft

step 2

In the right triangle ABE

Find the length side AB

tan(21^o)=\frac{AB}{50} ---> by TOA (opposite side divided by the adjacent side)

solve for AB

AB=tan(21^o){50}

AB=19.19\ ft

step 3

How many feet off the ground is the squirrel?

Subtract the length side segment AB from the length side segment AC

so

64-19.19=44.81\ ft

Melanie's room measures 10 ft by 12 ft. Her rug covers 90 ft². Explain how to determine the percent of floor covered by the rug.
Inessa [10]

\huge \bf༆ Answer ༄

Here's the solution ~

Area of floor is ;

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:10 \times 12

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:120 \: ft {}^{2}

Area covered by rug is ;

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:90 \: ft {}^{2}

So, the percentage of floor covered by rug is ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{90}{120}  \times 100

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{3}{4}   \times 100

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:3 \times 25

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:75  \%
