Find an for the arithmetic series with s16 = -288 And a1 =-21

Maru [420]

If $d$ is the common difference between terms in the sequence $\{a_n\}$ , then

$a_1=-21$
$a_2=a_1+d=-21+d$
$a_3=a_2+d=-21+2d$
...
$a_n=a_{n-1}+d=\cdots=-21+(n-1)d$

You're told that $S_{16}=-288$ (the sum of the first 16 terms in the sequence, presumably). Well, we know that

$S_{16}=\displaystyle\sum_{n=1}^{16}a_n=\sum_{n=1}^{16}(-21+(n-1)d)$
$S_{16}=\displaystyle(-21-d)\sum_{n=1}^{16}1+d\sum_{n=1}^{16}n$

Recall that

$\displaystyle\sum_{n=1}^kn=\frac{k(k+1)}2$

so that we have

$-288=16(-21-d)+\dfrac{16(16+1)}2d\implies d=\dfrac25$

So we get

$\begin{cases}a_1=-21\\\\a_n=-21+\dfrac25(n-1)\end{cases}$

The cost of a jacket increased from $90.00 to $103.50. What is the percentage increase of the cost of the jacket?

a_sh-v [17]

Answer:

So the Percentage Increase = 15 %

Step-by-step explanation:

Given:

Original price = $ 90.00

New Price = $103.50

To Find:

Percentage Increase = ?

Solution:

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Now In our Given Data

Difference in Value = New Value - Original Price

Putting in the values

Difference in Value = 103.50 - 90.00

= $13.50

Now we Know all the value and the formula is

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Putting in the values

Percentage Increase $=\frac{13.50* 100}{90.00}$ %

$=\frac{1350}{90.00}$ %

= 15%

which tells us that

Percentage Increase = 15 %

Six of the nine students are from middle gerogia state college. What is the probability that all three interviewed students are

ozzi

Answer:

0.2381 = 23.81%

Step-by-step explanation:

To calculate this probability, we can calculate the probability of each student of the 3 students interviewed being from middle georgia state college.

If inicially there are six students from middle georgia state college among the nine students, the probability of the first student chosen being from middle georgia state college is 6/9.

Then, as one student was already picked, we have now 5 students from middle georgia state college in a total of 8 students, so the probability of the second student will be 5/8.

In the same way, the third student will be picked in a group of 7 students, where 4 are from middle georgia state college, so the probability is 4/7.

Multiplying all the probabilities, we have the probability of all three students interviewed being from middle georgia state college:

P = (6/9) * (5/8) * (4/7) = 120/504 = 0.2381 = 23.81%
