Isme estimated that there are 50 students in the seventh-grade class. There are actually 40 students in the seventh-grade class.
A. What is Isme's percent error?

B. Out of the 40 students in the seventh-grade, 60% of the students carry a cell phone. What fraction of the students in the seventh grade class carry a cell phone? How many students in the seventh grade class carry a cell phone/

A) 25%

B) fraction: ⅗

Number: 24

Step-by-step explanation:

Error: 50 - 40 = 10

%error = 10/40 × 100 = 25%

60% = 60/100 = ⅗

⅗ × 40 = 24

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
