Mathematics

Answer:

35 km

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

28^2 + 21^2 = c^2

784+441 = c^2

1225 = c^2

Take the square root of each side

sqrt(1225) = sqrt(c^2)

35 = c

Answer:

35 km

Step-by-step explanation:

The pythagorean theorem states that a^2+b^2=c^2. (The hypotenuse is c)

So, we will plug a and b in.

28^2+21^2=c^2

Then, simplify.

784+441=c^2

1225=c^2

c=35

Therefore, the hypotenuse is 35 km.

Measure of Angle 2 = 100 degrees
measure of Angle 6 = 100 degrees

Since angle 2 and angle 6 are both 100 degrees, this makes them congruent angles. They are also corresponding angles as well.

The fact we have corresponding angles that are congruent leads to AB being parallel to CD. This is using the Converse of Corresponding Angles Theorem.

At the 2012 Summer Olympic Games in London, in the Men's Shot Put qualifying round, the distances ranged from 17.58 meters to 21
chubhunter [2.5K]

Answer:

One standard deviation above the mean means a z-score of 1.0. If we put this into the calculator as normalcdf(1,999) = .159

15.9 percent of the athletes would have a distance greater than 20.56 meters.

Now multiply the number of athletes by the percent.

.159 * 40 = 6.346 = about 6 athletes

c. about 6 athletes
