an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.
Check the picture below.
Answer:
The probability of selecting a sample mean of 13 or larger from this population is 0.0228
Step-by-step explanation:
A researcher selects a sample of 49 participants from a population with a mean of 12 and a standard deviation of 3.5.
We are supposed to find the probability of selecting a sample mean of 13 or larger from this population i.e.
Z=2
Refer the z table
Hence the probability of selecting a sample mean of 13 or larger from this population is 0.0228
