I give you a tricky one Express 108 ×125as a product of prime factors in exponential form
lana [24]

Answer:

108 \times 125=2^2 \times 3^3 \times 5^3

Step-by-step explanation:

To express the given product (108 X 125) as a product of prime factors

Step 1: Express each of the numbers as a product of its prime factors.

108=2^2 \times 3^3\\125=5^3

Step 2: Write the product together, and combine any like terms if any

Therefore,

108 \times 125=2^2 \times 3^3 \times 5^3

MULTIPLE CHOICE A thermometer is
pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

  • Thermometer accuracy = ±2°F
  • Thermometer reading = 17°F

<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :

  • Thermometer reading - thermometer accuracy

  • 17 - 2 = 15°F

<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :

  • Themometer reading - thermometer accuracy

  • 17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F

Paul, Colin and Brian are waiters.
Kisachek [45]

Add the ratios together: 2 + 3 +4 = 9

Divide the total tips by 9:

77.40 / 9 = 8.60

Multiply each portion of the ratio by 8.60:

2 x 8.60 = 17.20

3 x 8.60 = 25.80

4 x 8.60  = 34.40

The ratios are in order of the people:

Paul got 17.20

Colin got 25.80

Brian got 34.40

Brian got 34.40 - 17.20 = 17.20 more than Paul

the demand for a product for the last six years has been 15, 15, 17, 18, 20, and 19. The manager wants to predict the demand for
Marta_Voda [28]

Answer and explanation:

Given : The demand for a product for the last six years has been 15, 15, 17, 18, 20, and 19. The manager wants to predict the demand for this time series using the following simple linear trend equation : tr_t = 12 + 2t

To find : What are the forecast errors for the 5th and 6th years?

Solution :

Data : 15, 15, 17, 18, 20, and 19.

The simple linear trend equation is given as, tr_t = 12 + 2t

For t = 5 years

tr_t = 12 + 2(5)

tr_t = 12 +10

tr_t = 22

Observed tr_t = 20

Predicted tr_t = 22

Forecast error = Observed – Predicted = 20 – 22 = -2

Absolute forecast error = |-2| = 2 .

For t = 6 years

tr_t = 12 + 2(6)

tr_t = 12 +12

tr_t = 24

Observed tr_t = 19

Predicted tr_t = 24

Forecast error = Observed – Predicted = 19 – 24 = -5

Absolute forecast error = |-5| = 5.
