The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a me

nadezda [96]

The answer is between $175 and $295. The standard deviation rule tells us that for distributions that have the normal shape, approximately 99.7% of the observations fall within 3 standard deviations of the mean. Indeed, 175 = 235 − 3 * 20 and 295 = 235 + 3 * 20 are exactly 3 standard deviations below and above the mean, respectively.

Based only on the information given in the diagram, it is guaranteed that JKL ~ WXY.

Alika [10]

Answer:

Option A True

Step-by-step explanation:

we know that

The sum of the internal angles of the triangle is equal to $180\°$

In the triangle JKL

m∠L= $180\°-90\°-27\°=63\°$

The measurements of the angles of triangle JKL are $27\°-90\°-63\°$

In the triangle WXY

m∠W= $180\°-90\°-63\°=27\°$

The measurements of the angles of triangle WXY are $27\°-90\°-63\°$

therefore

Triangle JKL and triangle WXY are similar by AAA ( The AAA postulate states that if you can prove that all three angles of two triangles are congruent, you can prove the two triangles are similar)
