A number plus itself, plus twice itslef, plus 4 times itself, is equal to -104. what is the number?

Nutka1998 [239]

Let's represent this unknown number with the variable 'n'
n + n + 2n + 4n = -104

Explanations:
'n+n' - a number plus itself
'+2n' - plus twice itself
'+4n' - plus 4 times itself

Anyway:
n + n + 2n + 4n = -104
Simplify:
8n = -104
Divide both sides by 8:
n = -13

The number is -13
Good luck! If you need me to explain something in more depth, just ask :))

Mallory is training for a marathon. She ran for 15 minutes on the 1* day, 19

lilavasa [31]

the amount of time that she runs on the n-th day is:

T = 4min*n + 11min

And on day number 30 is:

T = 4min*30 + 11min = 133min

We know that:

She ran for:

15 minutes on the 1* day
19 minutes on the 2nd day
23 minutes on the 3rd day
27 minutes on the 4th day.

So on each consecutive day that she runs, she adds 4 minutes to the running time. This is a linear relationship.

So, if we define n as the day number, we can write the time T of running as:

T = 4min*n + b

Where b is a constant, notice that when n = 1 (the first day) the time of running is 15 minutes, then:

15 min = 4min*1 + b

15 min - 4min = 11 min =b

Then the amount of time that she runs on the n-th day is:

T = 4min*n + 11min

And on day number 30 is:

T = 4min*30 + 11min = 133min

An online merchant sells products that can be classified into the following non-intersecting categories: video games, electronic

Andrej [43]

Answer:

0.15 ( E )

Step-by-step explanation:

Assuming

video game to be : V

electronics : E

clothing : C

From the content of the question

V = 2c

hence E = 2/3 V - 1/5 C

= 2/3 ( 2c ) - 1/5 c

= $\frac{17c}{15}$

therefore : V = 2c and E = 17c / 15

assuming the number of clothing ( c ) = 15

V = 2*15 = 30 and E = ( 17 *15 ) / 15 = 17

Total number of items sold = V + C + E = 30 + 15 + 17 = 62

from here we can determine the probability that of the five items independently sold that there are 3 video game, 1 electronic item and 1 clothing item

attached below is the remaining part of the solution

Question is Incomplete, Complete question is given below.

Each morning papa notes the birds feeding on his birdfeeder. so far this month he has seen 59 blue jays, 68 black crows, 12 red robins and 1 cardinal. What is the probability of a blue jay being the next bird papa sees?

Answer:

The probability of a blue jay being the next bird papa sees is 0.421

Step-by-step explanation:

Given:

Number of outcomes of Blue jays = 59

Number of outcomes of Black crows =68

Number of outcomes of red robins = 12

Number of outcomes of cardinal = 1

Total Number of Birds = Number of outcomes of Blue jays + Number of outcomes of Black crows + Number of outcomes of red robins + Number of outcomes of cardinal = $59+68+12+1=140$

To calculate the probability, it is obtained by the formula number of outcomes / total number of possible outcomes.

Probability of of a blue jay being the next bird papa sees = $\frac{\textrm{Number of outcomes of Blue jays}}{\textrm{total number of birds}}= \frac{59}{140} = 0.421$

Hence, the probability of a blue jay being the next bird papa sees is 0.421
