Colt1911 [192]

Answer:

a_n = 2+6(n-1)

Step-by-step explanation:

Explicit Arithmetic Formula: a_n=a_1 + d(n-1)

a₁ is 1st term in sequence

<em>d</em> is common difference

<em>n</em> is term number

Step 1: Find <em>d</em>

d = 8 - 2 = 6

Step 2: Plug in variables into formula

a_n = 2+6(n-1)

Marat540 [252]

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

4a+4(120)=1080 (There are four 120^{\circ} and 4 a^{\circ}, they sum to 1080°)

4a + 480 = 1080

4a = 600

a = 150

Hope this helps :)

15 and 17 pls.. 15 points!!!!
Maurinko [17]

Step-by-step explanation:

15) 50 ÷ 2 = 25

17) Mean = 301, Mode = 40-50

(10+20) ÷ 2 = 15, (20+30) ÷ 2 = 25, (30+40) ÷ 2 = 35

(40+50) ÷ 2 = 45, (50+60) ÷ 2 = 55, (60+70) ÷ 2 = 65

(70+80) ÷ 2 = 75

• 15×4 = 60, 25×8 = 200, 35×10 = 350, 45×12 = 540

55×10 = 550, 65×4 = 260, 75×2 = 150

Mean = (60+200+350+540+550+260+150) ÷ 7

= 2110 ÷ 7

= 301.4285....

= 301

Sophia puts $250 in the bank with a 2.5% annual interest rate compounded monthly. If Sophia does not touch his money, how much m
Fittoniya [83]

Answer:

<h3> D) $276.26</h3>

Step-by-step explanation:

Deposited amount initially (P) = $250.

Rate of interest(r) = 2.5% compounded monthly = 0.025

Number of years (t) = 4.

Number of months in an year (n) = 12.

Formula for compound interest:

A=P(1+\frac{r}{n})^{nt}.

Plugging values in formula, we get

A= 250(1+\frac{0.025}{12})^{12\times 4}

A= 250(1.00208)^{48}

A= 250\times \:1.10506

A=276.26.

<h3>Therefore, correct option is  D) $276.26.</h3>
