Devante invests $4000 in two different accounts. The first account paid 6 %, the second account paid 11 % in interest. At the end of the first year he had earned $320 in interest. How much was in each account?

$
at 6 %

$
at 11 %

Answer:

Step-by-step explanation:

Equation (A)

5(x - 6) + 3x = [tex]\frac{3}{4}(2x-8)[/tex]

5x - 30 + 3x = [tex]\frac{3}{2}x-6[/tex]

8x - 30 = 1.5x - 6

8x - 1.5x = 30 - 6

6.5 x = 24

x = [tex]\frac{24}{6.5}[/tex]

x = 3.69

Equation (B)

2.7(5.1x + 4.9) = 3.2x + 28.9

13.77x + 13.23 = 3.2x + 28.9

13.77x - 3.2x = 28.9 - 13.23

10.57x = 15.67

x = 1.48

Equation (C)

5(11x - 18) = 3(2x + 7)

55x - 90 = 6x + 21

55x - 6x = 90 + 21

49x = 111

x = 2.27

Solutions from these equations from least to greatest;

1.48 < 2.27 < 3.69

Equation (B) < Equation (C) < Equation (A)

Answer:

The slope of AC is 2.

you go up 6 units and run 3 units

6/3 = 2

Answer:

Slope = 2.

Step-by-step explanation:

from the graph

x1 = 2 x2 = 5

y1 = 1 y2 = 7

Slope = (y2 - y1)/(x2 - x1)

= (7 - 1)/(5 - 2)

= 6/3

= 2.

Answer:

The answer is

[tex] \huge y + 3 = \frac{1}{2} (x - 6) \\ [/tex]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question we have the final answer as

[tex]y + 3 = \frac{1}{2} (x - 6) \\ [/tex]

Step-by-step explanation:

Answer:

The standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.

Step-by-step explanation:

Let X represent the number of adult Australian sheep dogs weighing 65 pounds or more.

It is provided that the probability of occurrence of X is, p = 0.40.

A sample of n = 14 adult dogs is studied.

Each dog's weight is independent of the others.

The random variable X follows a Binomial distribution.

The standard deviation of a Binomial distribution is:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

Compute the standard deviation of the number of dogs who weigh 65 lbs or more as follows:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

   [tex]=\sqrt{14\times 0.40(1-0.40)}\\\\=\sqrt{3.36}\\\\=1.83303\\\\\approx 1.83[/tex]

Thus, the standard deviation of the number of dogs who weigh 65 lbs or more is 1.83.

Answer:

Step-by-step explanation:

Simplify the following:

-(3 + 1/3) (-(2 + 7/10))

Hint: | Multiply all instances of -1 in -(3 + 1/3) (-(2 + 7/10)).

(-1)^2 = 1:

(3 + 1/3) (2 + 7/10)

Hint: | Put the fractions in 2 + 7/10 over a common denominator.

Put 2 + 7/10 over the common denominator 10. 2 + 7/10 = (10×2)/10 + 7/10:

(3 + 1/3) (10×2)/10 + 7/10

Hint: | Multiply 10 and 2 together.

10×2 = 20:

(3 + 1/3) (20/10 + 7/10)

Hint: | Add the fractions over a common denominator to a single fraction.

20/10 + 7/10 = (20 + 7)/10:

(3 + 1/3) (20 + 7)/10

Hint: | Evaluate 20 + 7.

20 + 7 = 27:

(3 + 1/3)×27/10

Hint: | Put the fractions in 3 + 1/3 over a common denominator.

Put 3 + 1/3 over the common denominator 3. 3 + 1/3 = (3×3)/3 + 1/3:

27/10 (3×3)/3 + 1/3

Hint: | Multiply 3 and 3 together.

3×3 = 9:

((9/3 + 1/3)×27)/10

Hint: | Add the fractions over a common denominator to a single fraction.

9/3 + 1/3 = (9 + 1)/3:

27/10 (9 + 1)/3

Hint: | Evaluate 9 + 1.

9 + 1 = 10:

10/3×27/10

Hint: | Express 10/3×27/10 as a single fraction.

10/3×27/10 = (10×27)/(3×10):

(10×27)/(3×10)

Hint: | Cancel common terms in the numerator and denominator of (10×27)/(3×10).

(10×27)/(3×10) = 10/10×27/3 = 27/3:

27/3

Hint: | Reduce 27/3 to lowest terms. Start by finding the GCD of 27 and 3.

The gcd of 27 and 3 is 3, so 27/3 = (3×9)/(3×1) = 3/3×9 = 9:
