If you roll a number cube, what is the probability that you will roll an even number?
Yanka [14]

Answer:

\frac{1}{2}

Step-by-step explanation:

Probability is calculated as

P = \frac{favourable outcome}{number of outcomes}

A favourable outcome is an even number , that is 2, 4, 6 , a total of 3

number of outcomes = 6 , that is 1, 2, 3, 4, 5, 6

Then

P( even number) = \frac{3}{6} = \frac{1}{2}

Allison is making fruit drinks for her friends.
Svetllana [295]

The number of cups of fruit Allison will need is = 4 ⅘ cups of fruits

<h3>Calculation of total quantity of fruits</h3>

The quantity of strawberries needed for each fruit drink= 3/5 cup

The quantity of blueberries needed for each fruit drink = 1/5 cup

Therefore the total quantity of fruits needed for each drink = 3/5 + 1/5

= 4/5

If 4/5 = 1 fruit drink

X = 6 fruit drinks

Make X the subject of formula,

X = 4/5 × 6

X = 24/5

X= 4 ⅘

Therefore, the number of cups of fruit Allison will need is = 4 ⅘ cups of fruits

Sesame Company purchased a computer system for $74,000 on January 1, 2018. It was depreciated based on a 7-year life and an $18,
amm1812

Answer: $24000

Step-by-step explanation:

Depreciation for 2018 = ($74,000 - $18000) / 7

= $56000/7

= $8000

Depreciation for 2019 = ($74,000 - $18000) / 7

= $56000/7

= $8000

Depreciation up to 2019 = $8000 + $8000 = $16000

Book value at end of 2019 = $74000 - $16000 = $58000

Revised residual value = $10,000

Number of remaining years = 4-2 = 2 years

Depreciation expensed for 2020 will be:

= ($58000 - $10,000) / 2

= $48000/2

= $24000
