Answer:
the sampling distribution of proportions
Step-by-step explanation:
A sample is a small group of observations which is a subset of a larger population containing the entire set of observations. The proportion of success or measure of a certain statistic from the sample, (in the scenario above, the proportion of obese observations on our sample) gives us the sample proportion. Repeated measurement of the sample proportion of this sample whose size is large enough (usually greater Than 30) in other to obtain a range of different proportions for the sample is called the sampling distribution of proportion. Hence, creating a visual plot such as a dot plot of these repeated measurement of the proportion of obese observations gives the sampling distribution of proportions
Explanation:
For the purpose of filling in the table, the BINOMPDF function is more appropriate. The table is asking for p(x)--not p(n≤x), which is what the CDF function gives you.
If you want to use the binomcdf function, the lower and upper limits should probably be the same: 0,0 or 1,1 or 2,2 and so on up to 5,5.
The binomcdf function on my TI-84 calculator only has the upper limit, so I would need to subtract the previous value to find the table entry for p(x).
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Angles ∠A and ∠B are 28° and 37°.
<u>We don't know:</u>
<u>So, we do this:</u>
- Add the 180°
- Solve the equation 180 - 28 - 37
<u>Solve:</u>
Angle ∠C is 115°.
Answer:
The answer to your question is a ) 127° b) 80°
Step-by-step explanation:
a) We have to consider that the sum of the interior angles in a triangle equals 180°.
Then,
89 + (5x - 7) + [180 - (14x + 1)] = 180
Simplification
89 + 5x - 7 + 180 - 14x - 1 = 180
5x - 14x = 180 - 89 + 7 - 180 + 1
- 9x = -81
x = -81 / -9
x = 9
Exterior angle = 14(9) + 1
= 127°
b) The process is the same that the previous problem
30 + (4x + 2) + [180 - (8 + 6x)] = 180
Simplification
30 + 4x + 2 + 180 - 8 - 6x = 180
4x - 6x = 180' - 30 - 2 + 8 - 180
-2x = -24
x = -24/-2
x = 12
The measure of the external angle is = 8 + 6(12)
= 8 + 72
= 80°
