X is partly constant, and partly varies as y. When y= 2 , x = 30 and when y = 6, x = 50
kirza4 [7]

"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

Let p be the population proportion for the following condition. Find the point estimates for p and q. In a survey of 1226 adults
weeeeeb [17]

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 \^{p}

(a)Point Estimate for p,

\^{p}=\frac{405}{1226} =0.3303

(b)Point estimate for q, \^{q}=1- (point estimate for p)

=1-0.3303

=0.6697

Use the formula for computing future value using compound interest to determine the value of an account at the end of 6 years if
nadezda [96]

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
