Answer: 1,045 passengers
Step-by-step explanation:
This question involves multiple steps. Let's first try to figure the number of children on the cruise.
The ratio of girls to the total number of children was 2:5. There are 198 boys.
This information tells me that for every 5 children, there's 2 girls and 3 boys.
Based off of this information, we can divide the total number of boys by 3 in order to find the number of children.
198÷3=66
Let's multiply 66 by 5 since that's the number of groupings based off the ratio.
66×5=330
Let's check the number of children. Since the ratio of girls to total children is 2:5 and we already confirmed there's 198 boys, there should be 132 girls. We can turn this ratio into a fraction where 2/5 of the children are girls. we can confirm this by multiply 330 by 2/5 (0.4) and getting 132.
There are 330 children on the cruise.
The ratio of the number of adults to the number of children was 13:6.
For every 6 children, there were 13 adults. Let's divide the number of children by 6 in order to find the number of groupings.
330÷6=55
Let's now multiply the groupings by 13 to find the number of adults.
55×13=715
So there should be 715 adults and 330 children on the cruise.
715+330=1,045
The slope of the following equation is -5, the y- intercept is (0,-2).

Answer:</h2>
We must determine the y-intercept, b using the slope and point provided.
Now that we know the y-intercept, b, we can create the equation of this line: <em>y = -3x + 1</em>.

Step-by-step explanation:
Your intervals are x=-2, and x=0. In this case, x=-2 will be a, and x=0 will be b.
To find the average rate of change, you have to first find f(-2) and f(0)
Then, f(0)
Now you know f(-2) is -11, and f(0) is 1.
Next, you plug these into the average rate of change formula, which is
Flug in -11 and 1 on the numerator, and -2 and 0 on the denominator.
