OlgaM077 [116]

Answer:

48% of people do NOT like walking

Step-by-step explanation:

First, write it as a fraction 13/25 (People who like jogging)

We want to find out the number of people who DON'T like walking, so we subtract 25-13=12. Put 12/25.

Lastly, convert into a percentage. Percent is out of 100, so we need to make the fraction out of 100. To do this multiply the numerator and the denominator by 4. 48/100.

=

48%

Hope this helps,

A series is defined by 5+9+13+17+.......+805 a. Find the number of terms of the series. b. Find the sum of the first 20 terms.​
puteri [66]

Answer: the number of terms of the series is 201 numbers

              the sum of the first 20 terms is 890    

the number of terms of the series is \frac{805-5}{4}+1=201

the series have:

u1 = 5

d = 4

=> u(n) = 5 + 4.(n - 1)

=> u(20) = 5 + 19.4 = 81

so the sum of the first 20 terms is (81 + 5).20/2 = 890

( u1 is the first number of the series, d is the  distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)
