B.) 37.5.. First you place all the numbers in order from least to greatest. Your mean is 25...and ur upper quartile because the 4 #'s fall even u add 35 and 40 and divide by 2... Which gives u upper quartile of 37.5 and lower quartile of 9. Hope this helps :)

Whats one fourth times 4

mylen [45]

1 because 4 as a fraction is 4/4 when mutiplying fractions you do the top number times the top number and the bottom number times the bottom number. Therefore 4/4 X 1/4= 4/4 which is equavilent to 1

If mAngleP = 85°, which is a possible measure for AngleY? mAngleY = 80° mAngleY = 85° mAngleY = 100° mAngleY = 180°

Serhud [2]

Answer:

Step-by-step explanation:

The complete question is

In the triangles, XY = MP and YZ = PN.

If mP = 85°, which is a possible measure for Y?

mY = 80°
mY = 85°
mY = 100°
mY = 180°

This problem is solved by simple reasoning.

In the figure, you can observe that angle Y is major than angle P, because the third side of the first triangle is major than the third side of the second triangle. So, the right answer must be higher than 85°, which is option 3, because it cannot be 180°, due to the graph doesn't show an straight angle at Y, and cannot be 80° because is lower than 85°

Therefore, the right answer is 100°.
