Answer:

The construction is shown below.

Step-by-step explanation:

Given:

A triangle RBI with \angle IRB=60\°,\angle RBI=90\°,BI=5.7\ cm

Since triangle RBI is a right angled triangle, the measure of angle RIB is given as:

∠RIB = 90° - 60° = 30°

Construction:

Step 1:

Draw a vertical line segment using a meter scale of length 5.7 cm. Label the top end point as 'I' and bottom point as 'B'.

Step 2:

Now, using a protractor construct an angle of 90° from point B with the line IB. Draw a line passing through the 90 degree mark and point 'B'.

Step 3:

Using the protractor, mark angle 30° from point 'I' with the line IB. Draw a line passing through the 30 degree mark till it intersects the line obtained in step 2.

Label the point of intersection of the lines from step 2 and step 3 as 'R'.

Thus, the resulting triangle obtained is ΔRBI.

Write a paragraph comparing the two classes' semester grades. Be sure to compare the extremes, the quartiles, the medians, and t
Gnom [1K]

Answer:

Second class have higher marks and greater spread.

Step-by-step explanation:

First box plot  represents class first. From the first box plot, we get

\text{Minimum value }= 53,Q_1=62,Median=80,Q_3=86,\text{Maximum value }= 89

Range=Maximum-Minimum=89-53=36

IQR=Q_3-Q-1=86-62=24

Second box plot  represents class second. From the second box plot, we get

\text{Minimum value }= 56,Q_1=62,Median=74,Q_3=89,\text{Maximum value }= 96

Range=Maximum-Minimum=96-56=40

IQR=Q_3-Q-1=89-62=27

First class has greater minimum value, first quartile of both classes are same, second class has greater median, first class has greater third quartile and first class has greater maximum value. It means second class have higher marks but class first have less variation.

Second class has greater range and greater inter quartile range. It means data of second class has greater spread.

Therefore, second class have higher marks and greater spread.

mezya [45]
Use the Pythagorean theorem:
5^2+x^2=15^2 \\&#10;25+x^2=225 \\&#10;x^2=225-25 \\&#10;x^2=200 \\&#10;x=\sqrt{200} \\&#10;x=\sqrt{100 \times 2} \\&#10;x=10\sqrt{2} \\&#10;x \approx 14.14

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
