A school principal of 890 students needs to determine what percentage of students passed and did not pass a statewide examination. 300 students passed. Round to the nearest percent. What percent did not pass the test?

Percentage = 66%

Step-by-step explanation:

Let the number of students that pass be P.

Let the number of students that fail be F.

Given the following data;

Total number of students, T = 890 students

P = 300 students

To find the percentage that failed;

First of all, we would determine the number of students that failed using the mathematical expression given below;

Total students, T = P + F

890 = 300 + F

F = 890 - 300

F = 590

Percentage = 66.29 ≈ 66%

Therefore, the percentage of students that failed or didn't pass is 66%.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
