Find the 60th term of the arithmetic sequence <br> −29,−49,−69,...

Mariulka [41]

Answer:

-1209

Step-by-step explanation:

Your sequence has first term a1 = -29 and common difference d = -20. Using these in the formula for the n-th term, we can find the 60 term.

an = a1 +d(n -1)

an = -29 -20(d -1)

a60 = -29 -20(60 -1) = -1209

You put $201 into a investment at 9% for four years. What will be the balance be at the end of four years??

spin [16.1K]

Depends if it is compounding interest or not. But assuming it is:

$201 x .09 = 18.09 (interest) = $219.09 (year 1)
$219.09 x .09 = 19.72 (interest) = $238.81 (year 2)
$238.81 x .09 = 21.49 (interest) = $260.30 (year 3)
$260.30 x .09 = 23.43 (interest) = $283.73 (year 4)

Please help thank you

grin007 [14]

Step-by-step explanation:

Y = 3x + 2

Putting value of y in equation 2

x + 12 = 3x + 2

12 - 2 = 3x - x

10 = 2x

10/2 = x

5 = x

Putting value of x in equation 1

Y = x + 12

Y = 5 + 12

Y = 17

The admissions office of a private university released the following admission data for the preceding academic year: From a pool

lina2011 [118]

Answer: Our required probability is 0.1695.

Step-by-step explanation:

Since we have given that

Number of male applicants = 4200

Number of female applicants = 3800

So, total number of applicants = 4200+3800 = 8000

Probability of male entered and subsequently enrolled is given by

$0.4\times 0.4=0.16$

Probability of female entered and subsequently enrolled is given by

$0.4\times 0.45\\\\=0.18$

Number of male entered and subsequently enrolled is given by

$0.16\times 4200\\\\=672$

Number of female entered and subsequently enrolled is given by

$0.18\times 3800\\\\=684$

So, Probability that a student who applied for admission will be accepted by the university and subsequently will enroll is given by

$\dfrac{672+684}{8000}\\\\=\dfrac{1356}{8000}\\\\=0.1695$

Hence, our required probability is 0.1695.
