In a mathematics test given to 15 students, the following marks (out of 100) se recorded. Find the mean 41,39,48,52,46,62,54,40,96,52.98,40 ,42,52.60

54.8

Step-by-step explanation:

41+39+48+52+46+62+54+40+96+52+98+40+42+52+60 = 822

822/15= 54.8

Hey there! I'll try to provide you with my best answer.

51.198 but if the question asks approximation then it's 51 .

In order to find we the mean, we add them all and divide the total by how many numbers there were. So,

(41 + 39 + 48 + 52 + 46 + 62 + 54 + 40 + 96 + 52.98 + 40 + 42 + 52.60)/13

= 665.58/13

= 51.198

Approximately its 51

Hope it helps! ^^

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
