In the first 25% of the produce, 7% of that is defective. Which means that 25%*93% is not defective.

=20.75% not defective.

In the second 30% of the produce, 6% is defective Which means that 30%*94%

=28.2% not defective

Now for the 3rd 45% of the produce, 4% is defective which means that

45%*96%

=43.2% not defective.

Added together, 20.75+28.2+43.2=92.15% not defective.

Can someone tell me why the answer is 2?

Ira Lisetskai [31]

Answer:

If we put x=2 in the given equation, we get the answer for the equation as 2

Given:

$\sqrt{-3 x+10}=x$

To find:

Why the answer is 2

Solution:

If we substitute the value x=2 in the given option, we get

$\sqrt{-3(2)+10}=2$

$\sqrt{-6+10}=2$

$\sqrt{4}=2$

Result:

Thus we can say that when substitute the value of x=2

We get the answer as $\sqrt{-3 x+10}=2$

Answer:

$x^4 + 4x^3 + 6x^2 + 7x + 2$

Step-by-step explanation:

We are asked to multiply the given polynomials.

$(x^ 2 + 3x + 1) \times (x^2 + x + 2)$

Multiply each term of the first polynomial to each term of the second polynomial.

$x^ 2 \times (x^2 + x + 2) = x^4 + x^3 + 2x^2$

$3x \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x$

$1 \times (x^2 + x + 2) = x^2 + x + 2$

Add the results

$(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)$

Combine the like terms

$x^4 + 4x^3 + 6x^2 + 7x + 2$

The answer is written in descending powers of x.

Answer:

x = 9.6

Step-by-step explanation:

Before we can figure out what x is, we need to figure out what the unlabeled side is. To figure that out, multiply the hypotenuse (12) by the sine of the angle labeled (34)

12 * sin(34)

sin(34) equals 0.559192903470747; I'll round it to 0.6 for convenience.

12 * 0.6

Now simply multiply 12 by 0.6 to get 7.2.

The unlabeled side is approx. 7.2 units long.

Now we know what the unlabeled side is. Now, to find x, find the square root of 12 squared minus 7.2 squared.

x = √12² - 7.2²

12 squared is 144; 7.2 squared is 51.84.

x = √144 - 51.84

Subtract 51.84 from 144 to get 92.16.

x = √92.16

The square root of 92.16 is 9.6 (on the spot!).

x equals 9.6.
