Answer:

  • Annie- 17 hours, Brian- 3 hours

Step-by-step explanation:

Let the number of hours Annie travelled be a, and same of Brian be b

<u>Then we have</u>

  • a + b = 20
  • a = 5b + 2

<u>Substituting a in the first equation</u>

  • 5b + 2 + b = 20
  • 6b = 20 - 2
  • 6b = 18
  • b = 3

<u>Then finding a</u>

  • a = 20 - 3 = 17

<u>So the answer is:</u>

  • Annie- 17 hours, Brian- 3 hours

(20 x 40) x 14 = ?
fredd [130]

To solve this problem, we must use the order of operations outlined by PEMDAS, which tells us that we should simplify or compute parentheses first, then exponents, multiplication, division, addition, and finally subtraction.

Using this method, we have to perform the multiplication inside the parentheses first.

(20 * 40) * 14

800 * 14

Finally, we must perform the final operation to simplify this expression, which is multiplication.

800 * 14 = 11200

Therefore, your final answer is 11200.

Hope this helps!

Given an actual demand of 64, a previous forecast of 59, and an of .3, what would the forecast for the next period be using simp
BartSMP [9]

Answer: 60.5

Step-by-step explanation:

The forecast for the next period using the simple exponential smoothing method is given by:

D\times \alpha+F(1-\alpha) , where D= actual demand for the recent period, \alpha= smoothing factor, F= forecast for the recent period .

Given: D= 64, \alpha=0.34 , F= 59

The forecast for the next period  = 64\times0.3+59(1-0.3)

\\\\= 64\times0.3+59\times0.7\\\\=19.2+41.3\\\\=60.5

Hence, the forecast for the next period = 60.5

murzikaleks [220]

Answer:

$594.03

Step-by-step explanation:

Using the exponential function;

A = Pe^-rt

Principal = $960

Rate r = 12% = 0.12

Time t = 4years

Substitute

A = 960e^-(0.12*)*4

A = 960e^-0.48

A = 960(0.61878)

A = 594.03

HEnce the worth after 4years will be $594.03
