4c2+6c-3c2-2c-3

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "c2" was replaced by "c^2". 1 more similar replacement(s).

Step by step solution :Step 1 :
Equation at the end of step 1 : ((((4•(c2))+6c)-3c2)-2c)-3 Step 2 :Equation at the end of step 2 : (((22c2 + 6c) - 3c2) - 2c) - 3 Step 3 :Trying to factor by splitting the middle term

3.1 Factoring c2+4c-3

The first term is, c2 its coefficient is 1 .
The middle term is, +4c its coefficient is 4 .
The last term, "the constant", is -3 

Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3

Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 4 .

-3 + 1 = -2 -1 + 3 = 2
Final result : c2 + 4c - 3

720 pt/h=______ qt/min

Gennadij [26K]

1 pt = 0.5 qts.....so 720 pts = (720 * 0.5) = 360 qts
1 hr = 60 minutes

360/60 = 6

720 pt/hr = 6 qts/min

In a random sample of students who took the SAT test, 427 had paid for coaching courses and the remaining 2733 had not. Calculat

Dvinal [7]

Answer:

The 95% confidence interval for the proportion of students who get coaching on the SAT is (0.1232, 0.147).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.
