Step-by-step explanation:

The sum of ages is 8+9+10 = 27, so each year of age is rewarded by ...

  216/27 = 8 . . . Rs

Then age 8 gets 8(Rs. 8) = Rs. 64

  age 9 gets 9(Rs. 8) = Rs. 72

  age 10 gets 10(Rs. 8) = Rs. 80

Answer:

±12.323

Step-by-step explanation:

A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the scores of a random sample of 238 graduating seniors and found the mean score to be 493 with a standard deviation of 97. Calculate the margin of error using the given formula. How could the results of the survey be made more accurate?

The formula for margin of Error =

±z × Standard deviation/√n

We are not given the confidence interval but let us assume the confidence interval = 95%

Hence:

z score for 95% confidence interval = 1.96

Standard deviation = 97

n = random number of samples = 238

Margin of Error = ± 1.96 × 97/√238

Margin of Error = ±12.323

The margin of error using the given formula will be ±12.323.

An error is a mistaken or erroneous action. In some contexts, an error is interchangeable with a mistake.

The discrepancy between the calculated value and the correct value is referred to as an "error" in statistics.

Given data;

Confidence interval = 95%

z score for 95% confidence interval = 1.96

Standard deviation = 97

n is a random number of samples = 238

The margin of Error is found as;

E =±z × Standard deviation/√n

[tex]\rm E= +z \times \frac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm E=\±1.96 \times \frac{97}{\sqrt{238} }\\\\ E=\±12.323 \[/tex]

Hence,the margin of error using the given formula will be ±12.323.

Answer:

Step-by-step explanation:

Let the price of DVDS = x

The price of movie tickets = y

The total price of five DVDs (all the same cost) and four movie tickets (all the same cost) is $138,

= 5x + 4y = $138

The total price of two DVDs and five movie tickets is $96.

2x + 5y = $96

Hence:

5x + 4y = $138.... Equation 1

2x + 5y = $96..... Equation 2

What is the price of one movie ticket?

Elimination method

2y = 204

y = 204/2

y = 102

The function value of given function at x = 3 is 63.

The given function is,

Answer:

$93,585.53

Step-by-step explanation:

If he is paying interest continually, you would use the formula Pe^rt

25000e^.33(4)= 3,585.53

If he used any other type of interest (monthly=12, quarterly=6, semi-annually=2, or annually=1) then you would use the formula p(1+r/n)^nt

25000(1+.33/n)^n(4)

n= put the number for how much you pay interest

Answer:

Number of Years to Double= 10.62 years

Step-by-step explanation:

First, we need to calculate the real annual interest rate:

Real annual interest rate= {[(i/12)+1]^12} - 1

Real annual interest rate=  [{(0.064/12) + 1]^12 - 1}

Real annual interest rate= 0.0659

Now, we need to use the rule of 72. The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double.

Number of Years to Double= 70/Annual Rate of Return

Number of Years to Double= 70/6.59

Number of Years to Double= 10.62 years

Answer:

the slope is 5/4

Step-by-step explanation:

use the formula y2 - y1 over x2 - x1, and plug in the coordinates into that

The slope of the line whose points are (1, 4) and (5, 9) will be 1.25.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The points are given below.

(1, 4) and (5, 9)

The slope of the line is given as,

m = (9 - 4) / (5 - 1)

m = 5/4

m = 1.25

The slope of the line whose points are (1, 4) and (5, 9) will be 1.25.

Answer:

option 4

Step-by-step explanation:

put like terms on either side

9x + 2a = 3a - 4x

subtract both sides by 2a

9x = a - 4x

add both sides by 4x

13x = a

divide both sides by 13

x = a/13

Answer:

We conclude that the value of the constant of proportionality.

Step-by-step explanation:

We know that if 'y' varies directly with 'x', we use the equation

y ∝ x

y = kx

where 'k' is called the constant of proportionality.

Given the equation

y = 14x

comparing with the equation

y = kx

Thus,

k = 14

Therefore, we conclude that the value of the constant of proportionality.
