Answer (Respuesta): B
3^2 (9) + 1 = 10 y 2^2 (4) + 1 = 5 por eso 10 - 5 = 5
68% +75 % +79 % +x ÷4≥ 80%
.68 + .75 + .79+x ÷4* 4 ≥ . 80*4
.68 + .75 + .79+x ≥ 3.2
2.22 + x ≥ 3.2
2.22 -2.22+x ≥ 3.2 -2.22
x ≥ 0.98
She has to get at least 98% to get an B.
Answer:
The mass would be 6x10^6
Step-by-step explanation:
In order to solve this, we simply need to multiply the two numbers together to get the new mass.
3x10^4 * 2x10^2 = 6x10^6
3 x 5 = 15
and now add the negative which is 3x-5= -15
The mean score is 3.08.
There is 1 quiz with score 1, so 1 point; 3 quizzes with score 2 for 3*2 = 6 points; 4 quizzes with score 3 for 4*3 = 12 points; 4 quizzes with score 4 for 4*4 = 16 points; and 1 quiz with score 5 for 5 points.
This is a total of 1+6+12+16+5 = 40 points.
This is out of 1+3+4+4+1 = 13 quizzes.
40/13 = 3.08
