The factor of 11 is going to be 77 because you have to stay in between 70 to 80
and 7 times 11 is 77. It also has to be a number in the 11 timetables. It can't be 88 because we can't cross 80 so the factor is going to be 77.
Hope it helps
Answer:
380
Step-by-step explanation:
285 / x = 75 / 100
Cross multiply 28500 = 75x
Divide by 75 380
1374 multiplied by 6 would be 8244

Let the boat speed in still water be b.
Let the current speed be c.
The speed going upstream is 20/4 = 5 mph.
The speed going downstream is 32/4 = 8 mph.
b - c = 5 ........(1)
b + c = 8 .......(2)
Adding equations (1) and (2) we get:
2b = 13
b = 13/2 = 6.5
Plugging in the value for b into equation (1) we find c = 1.5.
The boat speed in still water is 6.5 mph and the current speed is 1.5 mph.
Answer:
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Negative correlation:-
The negative correlation is a relation between two variables such that they are part of a function in which depends and independent variables move in different directions in terms of value.
<u><em>Positive correlation</em></u>
The variable x - value increases as y- value increases is called positive correlation.
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
<u><em>No correlation </em></u>
There is no pattern between two variables
there is no connect between two variables is called No - correlation
