I cant figure out 1/9 x 81/1 in my math book

Answer:

9

Step-by-step explanation:

Simplify before multiplying to make things easier.

\frac{1}{9}* \frac{81}{1}  

you can cross-simplify 9 and 81, which simplifies to:

\frac{1}{1}*\frac{9}{1}

\frac{1}{1} is equivalent to 1 and \frac{9}{1} is equivalent to 9, so all you're really doing is multiplying 9*1

9*1 = 9

so 1/9 * 81/1 is just 9.

X^4-x^2-42=0 <br>need to solve equation and find solution set
Ipatiy [6.2K]
That's a quadratic equation in x^2, which means we get an extra square root and \pm at the end.

x^4 - x^2 - 42 = 0

We factor,

(x^2 - 7)(x^2+6) = 0

x^2 = 7 \quad \textrm{or} \quad x^2 = -6

x = \pm \sqrt{7} \quad \textrm{or} \quad x = \pm i \sqrt{6}

Softa [21]

Answer:

0.006369

Step-by-step explanation:

Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.

By mere guessing p = probability for a right answer = 1/5 =0.20

There are two outcomes and each question is independent of the other.

X no of questions right is Bin (10,0.20)

the probability that the student will pass the test

= prob of getting more than 60%

=P(X\geq 6)

=0.006369
