Answer:
A) (7.6, 8.8)
which are the coordinates of the treasure.
Missing Problem Statement:
Given Options:
A) (11.4, 14.2)
B) (7.6, 8.8)
C) (5.7, 7.5)
D) (10.2, 12.6)
I have added the picture showing the traced map onto a coordinate plane to find exact location of treasure.
The coordinates of Tree are (16,21)
Coordinates of rock are (3,2)
Step-by-step explanation:
Let,
Coordinates of treasure be (a,b)
= distance from tree to treasure
=distance from rock to treasure
Given ratio between rock and tree, = 0.55_______(Equation.1)
which will be used to locate the treasure.
Now we just need to cross check by putting the coordinates given in the options one by one to find out value of ,
and checking if it satisfies the Equation 1.
Check (A) (11.4, 14.2)
= 14.8,
= 8.2,
= 1.8
Check (C) (5.7, 7.5)
= 6.13,
= 16.98,
= 0.36
Check (D) (10.2, 12.6)
= 12.8,
= 10.2,
= 1.25
Check (B) (7.6, 8.8)
= 8.2,
= 14.8,
= 0.55
Which satisfies Equation 1, such that ratio between rock and tree is 5:9 or = 0.55
So, the coordinates of the treasure are (B) (7.6, 8.8)
Answer:
a) 0.954
b) 0.937
c) 0.891
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 6 percent
Standard Deviation, σ = 1.3 percent
We are given that the distribution of particular interest rate is a bell shaped distribution that is a normal distribution.
Formula:
a) P(At least 3.8 percent.)
Calculation the value from standard normal z table, we have,
b) P(At most 8 percent)
Calculating the value from the standard normal table we have,
c) P(Between 3.8 percent and 8 percent. )
