Use sigma notation to represent the sum of the first six terms of the following sequence: −10, −13, −16, …
Anika [276]

Answer:

"<em>the summation from n equals one to 6 of quantity negative 7 minus 3 times n</em>"

Step-by-step explanation:

<u>General term of an arithmetic sequence:</u>

a_n=a_1+(n-1)r

Where

a_1 is the first term

n is the number of terms

r is the common difference

The value of r can be found by subtracting two consecutive values

r=a_2-a_1=-13+10=-3

Then

a_n=-10+(n-1)(-3)=-7-3n

If we want to sum the first six terms of the sequence, we must find

\sum_{n=1}^{n=6}(-7-3n)

The correct option is

"the summation from n equals one to 6 of quantity negative 7 minus 3 times n"

Out of a class of 150 students, two-fifths opted for German classes and one-third opted for Italian classes. The remaining opted
Yuliya22 [10]

Fraction of students that opted for French = \frac{4}{15}

The total number of students = 150

Fraction of students that opted for German = \frac{2}{5}

Fraction of students that opted for Italian = \frac{1}{3}

Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian

Fraction of students that opted for French = 1-\frac{2}{5} - \frac{1}{3}

Fraction of students that opted for French = \frac{15-6-5}{15}

Fraction of students that opted for French = \frac{4}{15}
