Answer:

Step-by-step explanation:

Since it is simple interest, you have to use the formula I = Prt.

(I is interest, P is principal (the starting amount), and r is the & rate as a decimal.

So, the interest would be

I = 543,300 (0.048) (2) = $52,156.80

The balance is the total amount. The balance would be the starting amount plus the interest.

Balance = 543,300 + 52,156.80 = $595,456.80

In a random sample of 60 dog owners enrolled in obedience training, it was determined that the mean amount of money spent per ow

Anton [14]

Answer: $(\$106.29,\ \$112.37)$

Step-by-step explanation:

Given : Sample size : $n=60$

The mean amount of money spent per owner = $\$109.33\text{ per class}$

Standard deviation : $\sigma=\$12$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

We know that the confidence interval for population mean is given by :-

$\mu\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$109.33\pm(1.96)\dfrac{12}{\sqrt{60}}\\\\\approx109.33\ \pm\ 3.04\\\\\approx(109.33-3.04,\ 109.33+3.04)\\\\(106.29,\ 112.37)$

Hence, the 95% confidence interval for the mean amount spent per owner for an obedience class will be $(\$106.29,\ \$112.37)$

Write the equation of the line if the slope = -3/5 and the line passes through (-4, 0). Show your work.

topjm [15]

Answer:

3x+5y+12=0

Step-by-step explanation:

This information is given in the question:

m=-3/5

x1=-4

y1=0

The formula for the equation of a line is:

y-y1=m (x-x1)

From this we can make a substitution

y-0=-3/5 (x--4)

Next simplify

y=-3/5 (x+4)

Multiply both sides of the equation by 5

5y=-3x-12

Make the right side of the equation equal to zero

3x+5y+12=0

This is the equation of the line in general form.

2x + 3y = 3 and x + 6y = -3

jekas [21]

Answer:

Step-by-step explanation:

Multiplying x+6y=-3 with 2 so its equal to first eqn,

Eliminating,

2x + 3y = 3 (1)

2x +12y = -6 (2) (because subtracting)

------------------

-9y =9

∴y=-1

eq. y in 1

2x -3=3

2x=3+3

x=6/2
