Answer:
P(A^B) = 22/15 or 1 7/15
Step-by-step explanation:
To find the P (A^B), we add the probability of events A and B.
2/3 + 4/5 = P, we need to find the LCD to add disimilar fractions
LCD is 15.
2(5)/15 +4(3)/15 = 10/15 + 12/15 = 22/15
Answer:
Null Hypothesis: p = 0.65.
Step-by-step explanation:
The null hypothesis is the expected population population, from an assumption deriving for example, from a previous experiment.
According to a researcher who was quoted in a New York Times article in March, 2011, 65% of U.S. community college students must take at least one remedial course in English
This means that the expected value of the population proportion is
, which is the null hypothesis.
Null Hypothesis: p = 0.65.

Step-by-step explanation:
Answer:
third choice
Step-by-step explanation:
The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles
If you fold this net up, you will get a triangular prism, NOT A PYRAMID.
A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.
Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.
For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.
Because a pyramid is where all the triangles must meet up at a point.
Hope this helps!
