Answer:
Step-by-step explanation:
d = √((9 -(-2))² + (5 - 2)²)
d = √(11² + 3²)
d = √130
d = 11.401754250...
d = 11.4 units
Answer:
a) The interval for those who want to go out earlier is between 43.008 and 46.592
b) The interval for those who want to go out later is between 47.9232 and 51.9168
Step-by-step explanation:
Given that:
Sample size (n) =128,
Margin of error (e) = ±4% =
a) The probability of those who wanted to get out earlier (p) = 35% = 0.35
The mean of the distribution (μ) = np = 128 * 0.35 = 44.8
The margin of error = ± 4% of 448 = 0.04 × 44.8 = ± 1.792
The interval = μ ± e = 44.8 ± 1.792 = (43.008, 46.592)
b) The probability of those who wanted to start school get out later (p) = 39% = 0.39
The mean of the distribution (μ) = np = 128 * 0.39 = 49.92
The margin of error = ± 4% of 448 = 0.04 × 49.92 = ± 1.9968
The interval = μ ± e = 44.8 ± 1.792 = (47.9232, 51.9168)
The way for those who want to go out earlier to win if the vote is counted is if those who do not have any opinion vote that they want to go earlier
The mean salary for Linda's employees is in thousands, is: 34,800.
<h3>What is the Mean of a Data Set?</h3>
- Mean of a data set is the average of the data set.
- To calculated the mean of a data set, use the formula: Mean = (∑fx)/∑f).
Thus:
∑fx = 974
∑f = 28
Therefore:
Mean = 974/28
Mean = 34.8
In thousands, the mean salary for Linda's employees is 34,800.

Step-by-step explanation:
average age of both = 40
average age of teachers = 35
average age of professors = 50
35 + 35 + 50 = 120
120 / 3 = 40
57508.5 and 120, it gives you ounces for first one and then asks for pounds and it gives you the number of ounces per pound on the side so you do 920136/16 and for the second you do the same thing but with the number of feet per yard and you would do 360/3
