7 0

Answer:

X^2 +Y^2 - 2X-4Y= 0

Step-by-step explanation:

From the circle eqn.

(x-a) ^2 +(y-b) ^2 =r^2

a=1, b= 2. r= 3

(x-1)^2 +(y-2)^2 =3^2

(x-1)(x-1)+(y-2)(y-2)=3^2

X^2 - 2x+1+y^2 -4y+4=9

X^2 +Y^2 - 2x-4y+5=9

X^2 +Y^2 - 2x-4y-4=0

Anthony borrowed $18,800 at 6% simple interest for 4 months. Determine the amount of interest.
anygoal [31]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
putting time into years for simplicity,
4 months ÷ 12 months/year = 0.333333 years,
then, solving our equation

I = $ 376.00

I = 18800 × 0.06 × 0.333333 = 375.999624
I = $ 376.00

The simple interest accumulated
on a principal of $ 18,800.00
at a rate of 6% per year
for 0.333333 years (4 months) is $ 376.00.

Suppose that we wish to assess whether more than 60 percent of all U.S. households in a particular income class bought life insu
IceJOKER [234]

Answer:

A. 0.0049

B. Yes

Step-by-step explanation:

Sample proportion = 0.64

N = 1000

Population proportion = 0.60

We solve for standard deviation

= √p(1-p)/n

= √0.60(1-0.60)/1000

= √0.60x0.40/1000

= √0.00024

= 0.0155

A.

The probability of sample >=0.64

Z>=0.64-0.60/0.0155

Z >= 0.04/0.0155

So z >= 2.5806

Using excel this equal to 0.0049

0.0049 is probability of sample proportion being 0.64 at least.

B.

This answer in a shows that than 60% of households in the united states income class purchased life insurance last year.
