How to find two consecutive integers for a product of 1295?

attashe74 [19]

Let the first integer be x; then the second is x+1.

The product of x and x+1 is x(x+1), and this product must equal 1295.

Thus, x^2 + x = 1295, or x^2 + x - 1295 = 0

Solve for x by completing the square:

x^2 + x + (1/2)^2 - (1/2)^2 - 1295 = 0

(x-1/2)^2 - 1/4 - 1295 = 0, or (x-1/2)^2 -5181/4 = 0,

Thus, x-1/2 = sqrt(5181/4), and so

x = 1/2+sqrt(5181/4) = 25.45

This could NOT be correct, since x and x+1 are CONSECUTIVE INTEGERS.

Suppose that a poll finds that 31.9% of taxpayers who filed their tax return electronically self-prepared their taxes. If thre

Aneli [31]

Answer: 0.0325

Step-by-step explanation:

Binomial probability distribution formula for x successes in n trials:-

$P(X=x)=^nC_x\ p^x\ (1-p)^{n-x}$ , where n is the number of trials , p is the probability of success.

Given : The probability that taxpayers who filed their tax return are electronically self-prepared their taxes : $p= 0.319$

If three tax returns submitted electronically are randomly selected, then the probability that all three were self-prepared is given by :-

$P(X=3)=^3C_3\ (0.319)^3\ (1-0.319)^{3-3}\\\\=(1) (0.319)^3(1)\\=0.032461759\approx0.0325$

Hence, the probability that all three were self-prepared =0.0325
