Answer:
There were 22 men in the sight-seeing tour
Step-by-step explanation:
If the number f women on the sight-seeing tour was less than 30, the closest number that can be divided by 5 is 25, so we suppose that there were 25 women, so with the ratio women(5): children(2) we can apply a rule of three, so we multiply 25*2 divided by 2, now we know that there were 10 children, now with the ratio of men(11): children(5) we apply another rule of three, and multiply 10*11 and then divide it by 5, and now we know that there were 22 men in the sight-seeing tour.
Answer:
4.1 shirts
Step-by-step explanation:
Mean can be found by adding all data points and dividing that by the total amount of data points.
There are 12 students selling shirt, which gives you 12 data points.
So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...
Which rounds to 4.1 shirts
We have been given that
![y = f ( x + 4 ) + 1\\ \\ f(4)=-2](https://tex.z-dn.net/?f=y%20%3D%20f%20%28%20x%20%2B%204%20%29%20%2B%201%5C%5C%0A%5C%5C%0Af%284%29%3D-2)
Now, we need to find an ordered pair that must be on the graph of
![y = f ( x + 4 ) + 1](https://tex.z-dn.net/?f=y%20%3D%20f%20%28%20x%20%2B%204%20%29%20%2B%201)
On substituting x=0 in the above equation, we get
![y = f ( 0 + 4 ) + 1\\ \\ y=f(4)+1\\ \\ \text{On substituting the value of f(4)= -2, we get}\\ \\ y=-2+1\\ y=-1](https://tex.z-dn.net/?f=y%20%3D%20f%20%28%200%20%2B%204%20%29%20%2B%201%5C%5C%0A%5C%5C%0Ay%3Df%284%29%2B1%5C%5C%0A%5C%5C%0A%5Ctext%7BOn%20substituting%20the%20value%20of%20f%284%29%3D%20-2%2C%20we%20get%7D%5C%5C%0A%5C%5C%0Ay%3D-2%2B1%5C%5C%0Ay%3D-1)
Therefore, the required ordered pair is given by (0,-1)
