Answer:
cos α = 8/17
Apply Pythagoras theorem for triangle ,
Let get unknown side of triangle is y
17^2 = 8^2 + y^2
17^2 - 8^2 = y^2
225 = y^2
y = sqrt(225)
y = 15
tan α = 15/8

Answer:
point is (13/4 , 17/2)
Step-by-step explanation:
Let (x1,y1) and (x2,y2) be the end points of a line segment, 'A' is the point on the line segment such that A divides the line segment in the ratio p : q then the coordinates of A (x,y) is given by,
x = x1 + p/w(x2 - x1) and y= y1 + p/w(y2 - y1) where w = p+q
It is given that,
Point A is located at (4, 8) and point B is located at (14, 10) .
Let P be the point on AB such that P divides AB in the ratio 1:3
<u>Find the coordinates of P(x,y)</u>
w = 1+3 = 4
x = x1 + p/w(x2 - x1) = 4 + 1/4(14 -4) = 4 + 10/4 =13/4
y= y1 + p/w(y2 - y1) = 8 + 1/4(10 - 8) = 8 + 1/2 = 17/2
point is (13/4 , 17/2)
Answer:
i think 37237
Step-by-step explanation:
Answer:
The probability that the mean daily revenue for the next 30 days will exceed $7500 is 0.0855
Step-by-step explanation:
It has been given that
Now, the formula for z-score of a normal distribution is given by
Substituting the known values, we get
Simplifying, we get
Now, we have to find that the daily revenue for next 30 days will exceed $7500.
Thus, we have to find
P(z>1.369238)
From the normal distribution table, we have
P(z>1.369238)= 0.0855
Therefore, required probability is 0.0855
