Suppose △JCD≅△MAY.
Kisachek [45]
The correct answer for this would be ΔCJD ≅ ΔAMY and ΔDCJ ≅ ΔYAM.
All we are doing for this is rearranging the order of the angles, as long as the order of the angles match with the original order.
The following answers are also correct:
ΔDJC ≅ ΔYMA
ΔCDJ ≅ ΔAYM
ΔJDC ≅ ΔMYA

Suppose that diameters of a new species of apple have a bell-shaped distribution with a mean of 7.43cm and a standard deviation
malfutka [58]

Answer:

Approximately 68% of the apples have diameters that are between 7.08cm and 7.78cm.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 7.43cm, standard deviation of 0.35cm.

What percentage of the apples have diameters that are between 7.08cm and 7.78cm?

7.43 - 0.35 = 7.08 cm.

7.43 + 0.35 = 7.778 cm.

Within 1 standard deviation of the mean, so approximately 68% of the apples have diameters that are between 7.08cm and 7.78cm.
