Answer:
16/31 days
Step-by-step explanation:
Add up all the days: 15+10+6=31
Add up the days with no rain: 10+6=16
With no rain as numerator and total as denominator you get an answer of 16/31
Times it by 3 and see what u get try see if it work
The value of a = 2.17 and b = 1.95.
<h3>What is regression line?</h3>
A regression line is a graphic representation of the regression equation expressing the hypothesized relationship between an outcome or dependent variable and one or more predictors or independent variables;
y=
Correlation:
r=0.964
R-squared:
r²=0.9292
Hence, value of a and b is 2.17 and 1.95.

Answer:

Step-by-step explanation:
We have been given a graph of the function f(x).
Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:




We see that graph has end points in opposite direction then the degree of polynomial must be ODD.
Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.
Only
satisfies the given points from graph.
Hence correct choice is
.
Answer:
30
Step-by-step explanation:
Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!
