b) The spinner is spun once more.
Estimate the probability of landing on purple.
c) If the spinner is spun another 1000 times,
about how many times would you expect it to land on blue?

Answers

Answer:

A) 60

B) 72/300

C) 150

Step-by-step explanation:

A) P(green) = ⅕

⅕ × 300 = 60

B) purple: 72

45+37+52+94+72 = 300

Therefore, 72/300

C) 1000 × (45/300)

150

a, The number of times is 60.

b. The probability for landing should be [tex]72/300[/tex]

c. The number of times is 150.

Calculation of the number of times and probability:

Since

a. The spinner shown is spun 300 times

and, the probability of green should be like [tex]1/5[/tex]

So here one-fifth of 300 should be 60.

b. The probability is

First the total be like

= 45+37+52+94+72

= 300

Now the probability is

=  [tex]72/300[/tex]

C) The number of times should be

[tex]= 1000 * (45/300)[/tex]

= 150

Answer:

Step-by-step explanation:

Maya makes trail mix by combining 1/2 cup of mixed nuts, 1/4 cup of dried fruit, and 1/8 cup of chocolate morsels. What is the total amount of ingredients in her trail mix? Explain how you solved the problem.

Answers

Answer:

7/8 of ingredients

Step-by-step explanation:

To calculate the amount of ingredients in Maya's trail mix, we should first come up with a common denominator to convert all the fractions to.

Our LCD here could be 8, because 8 is divisible by 2 and 4, our other denominators.

1/8 stays as 1/8.

1/2 = 4/8

since 1 x 4 = 4 and 2 x 4 = 8

1/4 = 2/8

since 1 x 2 = 2 and 4 x 2 = 8

1/8 + 4/8 + 2/8 gets us 7/8.

(( I assume you are looking for the total amount in fraction form ))

A $40,000 car depreciates in value about 18% per year for the life of the car. Determine the value of the car after 7,8, and 9 years. What is the rate of decay?

Answers

Answer:

Value after:

7 years = $9971.42

8 years = $8176.56

9 years = $6704.78

Rate of decay = 18%

Step-by-step explanation:

A $40,000 car depreciates in value about 18% per year for the life of the car.

Determine the value of the car after 7,8, and 9 years. What is the rate of decay?

The formula for Depreciation is

FV = PV( 1 - r)^t

Where

FV = Future value

PV = Present value = $40,000

r = Depreciation rate = 18% = 0.18

t = time in years

a) After 7 years

$40,000 (1 - 0.18)⁷

= $9971.4188227

= $9971.42

b) After 8 years

$40,000 (1 - 0.18)⁸

= $8176.5634346

= $8176.56

c) After 9 years

$40,000 (1 - 0.18)⁹

= $6704.7820164

≈ $6704.78

= $9971.42

The Rate of decay = 18%
