The scatter plot shows the number of minutes guya practiced the flute each day in a given week. what is guya's mean practice time per day during the given week? round to the nearest tenth, if necessary.
a. 35 min.
b. 35.6 min.
c. 35.7 min.
d. 40 min

Guya's mean practice time per day during the given week =  35.7 mins

Step-by-step explanation:

Look at the attached picture:

The plot tells us that Guya practiced 10 minutes on Sunday, 30 minutes on Monday, 20 minutes on Tuesday and so on

So, in the whole week she practice minutes.

10+30+20+40+50+40+60 = 250 minutes

The mean of a set of numbers is defined as the sum of the numbers divided by the number of given terms. So, we have seven numbers adding up to 250, and the mean is thus

250/7 = 35.714285

By rounding off we get:

35.7

Guya's mean practice time per day during the given week =  35.7 mins

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
