Answer:
94.15
Step-by-step explanation:
15.5 x 3.5= 54.25
22.8 x 1.75= 39.9
54.25+39.9=94.15
Answer:
11
Step-by-step explanation:
The slope of a linear regression is the rate of change of the line of the best fit
- The interpretation of the slope is that the wait time per staff is 1.62 minutes
- The slope value is realistic
The linear regression is given as:
y = -1.62x + 18
Where
- y represents the wait time
- x represents the number of staff
Using the above representations, the slope means that the wait time per staff is 1.62 minutes
Also, the slope value is realistic because time can be measured in decimals

Answer:

Step-by-step explanation:
Since we are in quadrant 2, sine is positive. Since sine is positive and cosine is negative, then tangent is negative.
Now I'm going to find the sine value of this angle given using one of the Pythagorean Identities, namely
.
If given
, then we have
by substitution of
.
Let's solve:
for
.

Subtract 4/9 on both sides:

Simplify:

Square root both sides:



===========

Multiplying top and bottom by 3 gives:

I'm going to move the factor of -1 to the top:
