Answer:

similar

Step-by-step explanation:

Similar triangles have equal angle measures.  The sum of the angles of any triangle must add up to 180°.  Since the angles of ΔDEF are 80° and 40°, then the third angle must be 60°:  80 + 40 = 120; 180 - 120 = 60. Also, the angles of ΔABC are 60° and 40°, which makes the third angle 80°: 60 + 40 = 100; 180 - 100 = 80.  Given that ΔDEF and ΔABC both have angles of 40°, 60° and 80°, then they are similar.

The red blood cell counts​ (in millions of cells per​ microliter) for a population of adult males can be approximated by a norma
skad [1K]

Answer:

(a) Minimum red blood cells 5.744 million cells per micro liter

(b) Maximum red blood cells 5.068 million cells per micro liter.

Step-by-step explanation:

Z-score formula is = \frac{x-u}{Standard deviation}

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.61 so then x will be;

x = 5.744

The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.14 so then x will be;

x = 5.068

The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.
