Answer: the number of boats that are in the marina is 105.
Step-by-step explanation:
Let x represent the number of boats that are in the marina.
Two-thirds of the boats in the marina are white. It means that the number of white boats in the marina is
2/3 × x = 2x/3
The remaining number of boats will be
x - 2x/3 = x/3
4/7 of the remaining boats are blue. It means that the number of boats that are blue is
4/7 × x/3 = 4x/21
The number of boats left would be
x/3 - 4x/21 = 3x/21
If there are 15 red boats, it means that
3x/21 = 15
3x = 21 × 15 = 315
x = 315/3
x = 105
H(x) = 3x + 12 + 5x + 10
h(x) = 8x + 22
in 4 hrs Colby can make: 3(4)+12 = 24$
in 4 hrs Dan can make: 5(4)+10 = 30$
together they make 22+30=52$ in 4hrs
if split equally that's 52/2=26$ a piece
yes, Colby doesn't make as much money so he will benefit from teaming up with Dan.
hello
this type of question can be described as a pythagorean triple
i.e they come in 3:4:5
the 3:4 signifies the adjacent to opposite sides
x can be calculated using pythagorean theorem
<em>C</em>
Approximately 95% of data falls within 2 standard deviations (±2) of the mean.
<em>Explanation</em>
According to the empirical rule of normal distribution:
Approximately 68% of the data falls within ±1 standard deviation of the mean
2. Approximately 95% of the data falls within ±2 standard deviations of the mean
3. Approximately 99.7% of the data falls within ±3 standard deviations of the mean.
Therefore, among the given options, only option C adheres to the empirical rule of the normal distribution. Therefore, the option C is correct
