Answer- 55
A triangle has 180 degrees
One side is 35 and we have the 90 degree angle
All we have to do is 35+90 then subtract that from 180

Answer:
0.0138 minutes/meter
Step-by-step explanation:
A linear regression model is given by the following general equation:

Where 'y' changes as a function of 'x', 'c' is a constant and 'm' is the slope that dictates the rate of change.
The given equation for the duration of a dive (DD), in minutes as a function of depth (D) in meters is:

Comparing this equation to the general model, the rate of 0.0138 minutes per meter, is our slope 'm'
Therefore, the slope of the regression line is 0.0138.

Answer: The mean temperature for the first eight days is 6.5 degrees
Step-by-step explanation: The most important piece of clue has been given which is the mean (average) for the observed data set, which is 7 days.
Note that the formula for the mean of a data set is derived as;
Mean = ∑x / f
Where ∑x is the summation of all observed data set and f is the number of data observed, that is 7. The formula now becomes;
6 = ∑x / 7
By cross multiplication, we now have,
6 * 7 = ∑x
42 = ∑x
This means the addition of all temperature observed on the first 7 days is 42. The temperature on the eighth day is now given as 10 degrees, this means the summation of all observed data for the first eight days would become 42 + 10 which equals 52. Therefore when calculating the mean for the first eight days, ∑x is now 52. The formula for the first eight days therefore is derived as follows;
Mean = ∑x / 8
Mean = 52 / 8
Mean = 6.5
The calculations therefore show that the mean temperature for the first eight days in January is 6.5 degrees
