Answer:
$69.375
Step-by-step explanation:
To find the total cost: you will add the actual cost of the rug, $64 and the additional shipping and handling cost, $5.375.

The total cost of the rug, including shipping and handling is $69.375
"X is partly constant and partly varies as y"
---> x = ky + p
when y=2,x=30 ---> 30 = 2k + p
when y=6,x=50 ---> 50 = 6k + p
subtract: 20 = 4k
k = 5
sub back in the first: 30 = 10+p
p = 20
x = 5y + 20
now you can answer B
notice this is just a variation of y = mx + b
Answer:
(a)0.3303
(b)0.6697
Step-by-step explanation:
Point estimation is the use of sample data to calculate a single value which serves as a best estimate of a given unknown population parameter.
Total Sample=1226
Number who said that they were not confident that the food they eat in country A is safe=405.
The point estimate of those who said that they were not confident that the food they eat in country A is safe is given as 
(a)Point Estimate for p,

(b)Point estimate for q,
1- (point estimate for p)
=1-0.3303
=0.6697

Step-by-step explanation:
Answer: the value of the account at the end of 6 years is is $8577
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 6000
r = 6% = 6/100 = 0.06
n = 4 because it was compounded 4 times in a year.
t = 6 years
Therefore,.
A = 6000(1+0.06/4)^4 × 6
A = 6000(1+0.015)^24
A = 6000(1.015)^24
A = $8577
