Answer:

$450

Step-by-step explanation:

First, find an equation that represents the proportional relationship between number of months (x) and amount spent (y).

A proportional equation can be represented in the form, y = kx, where,

k = constant of proportionality = y/x

Using a point on the line, (1, 50),

k = 50/1 = 50.

Substitute k = 50 into y = kx

The equation would be:

y = 50x

After 9 months (x), they would pay the following:

Substitute x = 9 into y = 50x

Thus:

y = 50(9)

y = 450

Educational Television In a random sample of 200 people, 159 said that they watched educational television. Find the 90% confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.

Answer:

The 90% confidence interval is   [tex]0.748  <  p <  0.842[/tex]      

Step-by-step explanation:

From the question we are told that

     The sample size is  n = 200

     The number of people that watched the educational television is [tex]k = 159[/tex]

Generally the sample proportion is mathematically represented as

               [tex]\^ p = \frac{159}{200}[/tex]

=>               [tex]\^ p = 0.795[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>     [tex]E =  1.645  * \sqrt{\frac{0.795 (1- 0.795)}{200} } [/tex]

=>     [tex]E = 0.04696 [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>    [tex]0.795  -0.04696  <  p <  0.795 + 0.04696[/tex]

=>    [tex]0.748  <  p <  0.842[/tex]

Answer:

first you find out how much will 1/2 kg of carrot cost, that way you can multiply it by 3 to get what 3/2 cost.

So, 3÷ 5 = 0.6 per 1/2 kg. Then 0.6 × 3 = 1.8 dollars for 3/2 kg

Answer:

Option A

Step-by-step explanation:

We know that Mia's frog only jumped [tex]\frac{4}{5}[/tex] the distance of Chloe's frog - which means that Mia's frog must be behind Chloe's frog. Therefore, Mia's frog must also not be in first place.  

We also know that Tony's frog jumped [tex]1\frac{1}{4}[/tex] the distance of Chloe's frog - meaning that Tony's frog jumped further than Chloe's frog, since it is above 1. So, Tony's frog is ahead of Chloe's frog. Therefore, Chloe's frog cannot be in first place either.

Let's look at the clues gathered so far:

Using logic, the only option that meets these requirements would be option A. Tony would be ahead of Chloe, Mia would be behind Chloe, and neither of the girls' frogs would be in first place. You could also use the process of elimination to get rid of the other answers.

Answer:

The total interest the account earned was $88.41.

The ending balance in the account is $1,163.41.

The account earned $25.26 in interests in the first year.

Step-by-step explanation:

The simple interest is one that does not accumulate to the initial capital, that is to say that the capital does not accumulate over the years.

Therefore, if Brian deposited $ 1,075 in an account with an interest of 2.35% per year for 3 and a half years, to obtain the total interest generated by the account, the following calculation must be performed:

(1,075 x 2.35 / 100) x 3.5 = X

25.2625 x 3.5 = X

88.41 = X

Thus, the interest generated during the first year was $ 25.26, while the accumulated interest during 3 and a half years was $ 88.41. In turn, since 88.41 + 1,075 equals 1,163.41, that is the resulting amount after the end of the investment.

Answer:

16x²

Step-by-step explanation:

since all sides of a square are equal, we just multiply 4x by 4x. this gives us 16x².

The area of square with side length 4x is 16x.

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.

Given,

The side length of a square is 4x

We need to find the area of square.

As we know that area of square = 4a.

Where a is the length of side of a square.

In a square all the four sides will have same length.

a=4x

Area of square=4(4x)

=16x

Hence the area of square with side length 4x is 16x.

Answer:

let this previous income be x

then 8% of (x-2000) = 3000

     or, 8/100*(x-2000) = 3000

Step-by-step explanation:

13 feet is the length of the other side of the room.

The formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here, 2inches =5feet thus 1 inch is equivalent to 5/2 feet and let the length of the other side is x

now area of the room is 24.96 inches²

Thus in feet the area is 24.96×(5/2)²=156 feet²

Also 12 × x = 156

             x  = 13 feet

Hence the length of the other side is equal to 13 feet

Correct principal is $1200.

Answer:

R = 6.736%

Step-by-step explanation:

Formula for simple interest is;

Interest = PRT/100

We are given;

Principal; P = $1200

Time; T = 6 years

Interest; I = $485

Rate; R =?

From, Interest = PRT/100, we have;

485 = 1200 × R × 6/100

Making R the subject gives;

R = 485 × 100/(6 × 1200)

R = 6.736%
