The answer is 42 3/4 for this question

Answer:

320

Step-by-step explanation:

The given series is an illustration of an arithmetic series, where the sum of first 10 terms of the series is -160.

Given

[tex]2 + (-2) + (-6) + (-10) +.......[/tex]

First, we calculate the common difference of the series

[tex]d = T_2 - T_1[/tex]

[tex]d = -2 -2[/tex]

[tex]d = -4[/tex]

The sum of the first nth term of an arithmetic series is:

[tex]S_n = \frac n2(2a + (n - 1)d)[/tex]

Where:

[tex]n = 10[/tex] ---- i.e. sum of 10 terms

[tex]a = 2[/tex] --- the first term

[tex]d = -4[/tex] --- the common difference

So, we have:

[tex]S_{10} = \frac{10}{2}(2 \times 2 + (10 - 1) \times -4)[/tex]

[tex]S_{10} = 5(4 + 9 \times -4)[/tex]

[tex]S_{10} = 5(-32)[/tex]

[tex]S_{10} = -160[/tex]

Hence, the sum of 10 terms of the series is -160.

Step-by-step explanation:

Answer:

x=27

Step-by-step explanation:

You want to isolate the variables so you subtract 5 from both sides. Therefore the equation will be 2/3x-1/9x=15. You want to take away the fraction because no one likes fractions. You have to multiply everything by 9. Therefore, the equation will be 6x-x=135. 5x=135. You want to isolate x so you have to divide each side by 5. x=135/5. Simplify to get x=27.

x is [tex]\frac{1}{3}[/tex] of y

AND

y is [tex]\frac{3}{4}[/tex] of (x+y)

Step-by-step explanation:

x:y is 1:3

=>  y is bigger than x

=>  y is 3x bigger than x

=>  y = 3 lots of x

=>  [tex]y =[/tex] [tex]3x[/tex]

=>  [tex]\frac{y}{3}[/tex] [tex]= x[/tex]

=>  [tex]\frac{1}{3} y[/tex] [tex]= x[/tex]

So x is [tex]\frac{1}{3}[/tex] of y

y is [tex]\frac{3}{4}[/tex] of (x+y)

If x = 1 and y = 3 (substitute in values)

=>  3 is [tex]\frac{3}{4}[/tex] of (4)

=>  3 is [tex]\frac{3}{4}[/tex](4)

=>  3 is ([tex]\frac{3}{4}[/tex]x4)

=>  3 = 3

Therefore, y is [tex]\frac{3}{4}[/tex] of (x+y) is true

So the answers are:

x is [tex]\frac{1}{3}[/tex] of y

AND

y is [tex]\frac{3}{4}[/tex] of (x+y)

Answer: I think it's The Third Point Unsure

The solution is, the right answer is :

Group 1: (5, 61); Group 2: (15, 73); Group 3: (25, 79)

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

Minutes studying(x) 0 , 5 , 10 , 10 , 15 , 20 , 25 , 30 , 30

Test score(y)            68, 61, 54, 64, 73, 76, 80, 79, 85

The median of x is 15 (The middle value)

Median of y would be 73 (The middle value)

So group 2 would be (15,73)

Here is the sequence 'x' without median 0 , 5 , 10 , 10, 15

The median would be 10.

Here is the sequence 'y' without median 54, 61, 64, 68, 73

The median is 61.

Hence,

So group 1 will be (5, 61).

73, 76, 79, 80, 85 median of 'y' would be 79

15 , 20 , 25 , 30 , 30 median of 'x' would be 25

so group 3 would be (25 , 79)

Therefore the right answer is :

Group 1: (5, 61); Group 2: (15, 73); Group 3: (25, 79)
