Complete the statements about the series
AleksAgata [21]

Answer:

Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.

This means that the value of k will go from 0 to 4, then all the numbers in the sum are:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

So we have 5 terms in our series.

b) to see the sign in each term, we must solve the powers, remember that:

(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:

(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4

= 1 -1/2 + 1/4 - 1/8 + 1/16.

So the sign in each term of the series alternates.

Which situation best shows causation?
dangina [55]

A cause and effect relationship exist between two variables, when one

variable event is made to happen by the other variable.

The situation which best shows causation is option <u>B) The amount of time a </u>

<u>cell phone is used affects the charge of the battery</u>.

Reasons:

Causation is the condition in which the occurrence of an event is caused by

or contributed to by another event. Such that the incident or observation

identified as the cause is responsible for the event, while the the

occurrence of the event depends on the cause being put in place.

  • Option A) A rectangle of a given width can have different dimensions of length

  • Option C) Milkshakes and ice cream bars can have different customer base, such that the number of milkshake and ice cream bars sold can be equal

  • Option D) The balls used in a soccer match are provided by the officials of the game

Therefore;

  • The situation which shows causation is B) <u>The amount of time a cell phone is used affects the charge of the battery</u>.

The option is correct because, a cell phone is powered by battery, and

therefore, the more the cell phone is used, the battery power is used up

and therefore, the charge on the battery is reduced.
