Answer:

x = 15

Step-by-step explanation:

A full circle = 360°

Therefore,

(8x - 10)° + (6x)° + (10x + 10)° = 360°

Solve for x

8x - 10 + 6x + 10x + 10 = 360

Add like terms

24x = 360

Divide both sides by 24

x = 360/24

x = 15

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15. N an 1 4 2 −12 3 36 t

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is $\sum_{n=4}^{15} 5(-2)^{n-1}$$$

<h3>What is sequence ?</h3>

Sequence is collection of numbers with some pattern .

Given sequence

$a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20$

We can see that

$\frac{a_1}{a_2}=\frac{-10}{5}=-2\\$

and

$\frac{a_2}{a_3}=\frac{20}{-10}=-2\\$

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now $n^{th}$ term of this Geometric progression can be written as

$T_{n}= 5\times(-2)^{n-1}$

So summation of 15 terms can be written as

$\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$$

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is $\sum_{n=4}^{15} 5(-2)^{n-1}$$$

omeli [17]

Answer:

basketball= 66.66 infinite%

baseball=42.86%

Step-by-step explanation:

if you divide 14 by 21 you get .66 infinite which is 66.66 infinite%

divide 9 by 21 you get around .4286 which is 42.86%
