Bbbbbbbbbbbbbbbbbbbbb is the answer
Answer:
The answers to the questions are
a) The average number of coconut palms on the randomly chosen side is 49.5 coconut palms
b) The projected number of palms on the entire farm is 3168 coconut palms.
Step-by-step explanation:
(a) The average is given by ∑fx/∑f = (∑x)/n
The sum of the number of coconut palms in the random sample of 10 acres is as follows
∑x = 56+43+62+63+33+34+38+51+59+56 = 495
n = 10
Therefore the average = 495/10 = 49.5 palm tree per acres
The average number of palm tree per acre = 49.5 palm tree
b) To project the number of coconut palms on the entire farm, we note that the average palm tree per acre = 49.5 coconut palms
Number of acres = 64
∴ Projected number of coconut palms in the farm = (Average number of palm tree per acre) × (Number of acres in the farm)
= 64 × 49.5 = 3168 coconut palms.
Answer:
The value of the bond when Tyler's mom purchased it was $150
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
where
a is the initial value (y-intercept)
b is the base
r is the rate
b=(1+r)
In this problem
r=4%=4/100=0.04
b=1+0.04=1.04
substitute
where
x is the number of years since the savings bond was purchased
f(x) is the value of the savings bond
For x=1
f(x)=$156
substitute
Solve for a
therefore
The value of the bond when Tyler's mom purchased it was $150
Can you provide a picture of the two figures .?
Answer:
225
Step-by-step explanation:
x + y + z = 1305
x = 360
y = 360×2 = 720
z = 1305 - 360 - 720 = 225
