The scatter plot shows the number of students per class at monida middle school and the number of magazine subscriptions each class sold for a fund-raiser. about how many subscriptions did the class of 30 students sell?
a. about 185 subscriptions
b. about 175 subscriptions
c. about 165 subscriptions
d. about 195 subscriptions

Option:B is the correct answer.

B.  about 175 subscriptions  

Step-by-step explanation:

We have a scatter plot that represents or shows the number of students per class at Monida Middle School and the number of magazine subscriptions each class sold for a fund-raiser.

So, we are asked to fund approximate number of subscriptions that were sold by the class of 30 students.

So, as from the scatter plot we could see that the number of subscriptions sold by a class of 30 students is close to 180 but did not reach 180.

Hence, the correct answer is:

About 175 subscriptions.

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
