In right triangle DEF, it is known that Cos D = (12/13) and Cos F = (5/13). If FD = 39, then DE = ? Hint, draw the right triangl
AnnyKZ [126]

Answer:

The value of the line segment ED is 36.

Step-by-step explanation:

The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:

\cos D = \frac{ED}{FD} (1)

\cos F = \frac{EF}{FD} (2)

If we know that \cos D = \frac{12}{13} and FD = 39, then the length of the line segment ED is:

ED = FD\cdot \cos D

ED = 39\cdot \left(\frac{12}{13} \right)

ED = 36

The value of the line segment ED is 36.

The number of pages read by two students each day for 5 days are listed in the table. Which statements are true about the data s
monitta

Answer:

  • The means for both data sets are equal.
  • The range of the number of pages Lionel read is greater than the range of the number of pages Aaron read.
  • The range of the number of pages that Lionel read is 75.

Step-by-step explanation:

Given

Lionel

90, 45, 30, 25, 15

Aaron

55, 19, 40, 16, 75

in the first case; For Lionel;

Mean = (90+45+30+25+15 )/5 = 41 and

Range = (90-15)=75

The second case; Aaron

Mean = (55+19+40+16+75)/5 = 41 and

Range = (75-16)= 59

Therefore;

Both data sets have the same mean but different range.

The range of the number of pages Lionel is 75, which is greater than the range of the number of pages Aaron read, which is 59.
