The missing number is 29.6
The rule shown in this is n - 7.1
So 36.9 - 7.1 = 29.6
And to check it 29.6 - 7.1 = 22.5
Answer:
45.54m
Step-by-step explanation:
Refer the attached figure
Scarlett's height = AB = 1.65 meters
She stands 90 meters away from the dam i.e. BE = AC = 90 m
She records the angle of elevation to the top of the dam to be 26º i.e. ∠DBE = 26°
Height of the Dam = DC = EC+DE
AB = EC = 1.65
In ΔBDE
Height of the Dam = DC =1.65+43.89=45.54 m
Hence the height of the dam is 45.54 m.
Answer: B and E
Step-by-step explanation: Trust me, this is correct
The total number of different routes that a fire truck can travel the m-distance from F to Z = 4 (Option C).
<h3 /><h3>What is a graph?</h3>
A graph refers to a diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.
Now,
Firstly, refer to the graph attached.
- The graph can be used to manually calculate the number of routes that lead from F to Z.
- F is four m-distances from Z.
- Now, manually calculate the m-distance of the path from F to Z using the 4 boxes that represent it. We discover 6 distinct pathways, each with an m-distance of 4.
Hence, The total number of different routes that a fire truck can travel the m-distance from F to Z = 4 (Option C).

Answer:
The margin of error is of 0.1282 = 12.82%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
A survey conducted by General Motors of 38 drivers in America, 34 indicated that they would prefer a car with a sunroof over one without.
This means that
99% confidence level
So , z is the value of Z that has a p-value of , so .
What is the margin of error?
The margin of error is of 0.1282 = 12.82%.
