Answer:
Step-by-step explanation:
25%=25/100= 1+4=5
1 is loss on selling price 4 so cost price =1+4=5
Then loss on cost price = 1/5x100=20%
Using the line of best-fit, it is found that the residual for the player is of 12.6.
<h3>What is the residual for a line of best-fit?</h3>
A residual is given by the difference <u>between the observed point and the predicted point</u>.
In this problem, the expected score over x hours is given by:
f(x) = 280.3 + 85.7x.
Hence, for 3 hours, the predicted score is given by:
f(3) = 280.3 + 85.7 x 3 = 537.4.
The observed score was of 550, hence the residual is given by:
R = 550 - 537.4 = 12.6.

Answer:
depth of swimming pool = 2.4 meters
Step-by-step explanation:
Volume of the swimming pool = l x b x h = 3000
Volume of the swimming pool = 50 x 25 x h = 3000
h = 2.4 meters
Answer:
86.19°
Step-by-step explanation:
Let x represent the missing value.
The given trigonometric equation becomes:
We take the inverse tangent of both sides to obtain:
This implies that;
We use at least a scientific calculator to evaluate this and obtain:
To the nearest hundredth, the missing value is
