On the occasion of its 10-year anniversary, AJ Inc. sells lucky draw tickets. If the customers are interested in the lucky draw contest, then they have to purchase a ticket for $15. The gift could be worth $115, $215, $315, or nothing. The probability of each event is given below. What is the value of the standard deviation
Probability 0.35 0.26 0.21 0.18
Amount gained $100 $200 $300 -$15
Option;
a) $11,143
b) $106
c) $10,200
d) $147
Answer:
the standard deviation is 106
Option b) $106 is the correct Answer
Step-by-step explanation:
Given the data in the question;
let the random variable be x
x = amount gained by customers in a lucky draw contest
so
Variance (x) = [∑(x² × P(x))] - [(∑(x × P(x))²]
so
x x² p(x) x.p(x) x².p(x)
$100 10,000 0.35 35 3,500
$200 40,000 0.26 52 10,400
$300 90,000 0.21 63 18,900
-$15 225 0.18 -2.7 40.5
TOTAL 147.3 32,840.5
Variance (x) = [∑(x² × P(x))] - [(∑(x × P(x))²]
we substitute;
Variance (x) = 32,840.5 - (147.3)²
Variance (x) = 32,840.5 - 21,697.29
Variance (x) = 11,143.21
Now Standard Deviation = √variance
so, S.D = √11,143.21
S.D = 105.56 ≈ 106
Therefore, the standard deviation is 106
Option b) $106 is the correct Answer

An amount of $44,000 is borrowed for 9 years at 3% interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid
back?
Answer:
A= $52,190.93
Step-by-step explanation:
A = $ 52,190.93
A = P + I where
P (principal) = $ 40,000.00
I (interest) = $ 12,190.93
Calculation Steps:
First, convert R percent to r a decimal
r = R/100
r = 3%/100
r = 0.03 per year,
Then, solve our equation for A
A = P(1 + r/n)nt
A = 40,000.00(1 + 0.03/1)(1)(9)
A = $ 52,190.93
Summary:
The total amount accrued, principal plus interest,
from compound interest on an original principal of
$ 40,000.00 at a rate of 3% per year
compounded 1 times per year
over 9 years is $ 52,190.93.
In an urban area, 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog owners in this urban area if they pay for someone to walk their dog. What is the probability that more than 30% of the owners in the sample pay for someone to walk their dog?
A. 0.439
B. 0.519
C. 0.561
D. 0.586
Answer:
c 0.561
Step-by-step explanation:
did the test on edge
The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.
Calculation of the probability:Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog
So
= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50
= P(z > - 0.1530)
= 0.5608
= 0.561
Hence, the option c is correct.

write an equation in slope-intercept form for the line that has a slope of 4 and passes through the point (3,24)
Answer:
y = 4x + 12
Step-by-step explanation:
y = mx + b
'm' represents slope
'b' represents the y-intercept
use the slope and the point (3,24) as your x and y inputs to find 'b'
24 = 4(3) + b
24 = 12 + b
b = 12
y = 4x + 12

What is the value of the fourth term in a geometric sequence for which ay =
10 and r = 0.5?
Answer:
1.25
Step-by-step explanation:
a = 10 and r = 0.5
The formula for calculating any term in a geometric sequence is a (the first term) times r (the common ratio) raised to the power of n - 1.
In this case n = 4, since we're looking for the fourth term.
so,
Un = ar^n-1
= ar^4-1
= ar^3
U4 = 10 × 0.5^3
= 10 × 0.125
= 1.25
