Answer:

4/7 of his marbles aren't blue or green.

Step-by-step explanation:

1/7 + 2/7 = 3/7 marbles are either blue or green in total.

7/7 - 3/7 = you're left with 4/7 not blue or green marbles.

If your starting salary were $50,000 and you received a 4% increase at the end of every year for 15 years, what would be the tot
ycow [4]

<u>Answer-</u>

<em>The total amount you would have earned over the first 16 years is </em><em>$90047.20</em>

<u>Solution-</u>

The exponential function that would given the growth is,

P'=P(1+r)^t

Where,

P' = Future value,

P = Current value = $50000

r = rate of change = 4% = 0.04

t = time = 15 year (not 16 because the the increment occurs at year end and we want to get the value at the beginning of 16th year)

Putting the values,

P'=50000(1+0.04)^{15}

=50000(1.04)^{15}

=90047.20

Therefore, the total amount you would have earned over the first 16 years is $90047.20

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the ta
german

Based on the number of songs in each genre that Josiah listened to, the statements about his solution that are true are:

  • He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
  • He did not multiply the numerator and denominator by the correct number to equal 1,500.
  • He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

<h3>What did Josiah do wrong?</h3>

To find the average of the number of rock songs, he should have taken the average of rock songs he listened to which were 4 and 6:

= (4 + 6) / 2

= 5

Because he has a total of 1,500 songs on his player, he should have multiplied both the numerator and denominator by a number that would lead to 1,500 which is 75 and not 30.
