Is 300 degrees the same as -60 degrees in a drawing?

1 answer:

8 0

No.

Inside a circle, where the lines are drawn inside a 300 degrees angle will correspond with a 60 degrees angle, but the shaded parts are different. However, there is technically no such thing as a negative angle, so your answer is No.

hope this helps

An urn contains 8 pink and 5 red balls. Six balls arerandomly drawn from the urn in succession, with replacement.That is, after

slega [8]

0.088

Step-by-step explanation:

The total number of balls in the urn is;

8 + 5 = 12

Because the pink balls are 8, then the probability of picking a pink ball from the urn is;

8/12

To get the probability that all 6 balls drawn from the urn are pink, we will use the AND probability rule of the mutually exclusive events which means we’ll multiply the probabilities of each of the six pink balls;

8/12 * 8/12 * 8/12 * 8/12 * 8/12 * 8/12

= 0.088

Find the partial fraction decomposition of x-3/x(x^2+3)

Setler [38]

Answer:

-1 / x + (x + 1) / (x² + 3)

Step-by-step explanation:

(x − 3) / (x (x² + 3))

There are two factors in the denominator, so split this into two fractions with unknown numerators:

A / x + (Bx + C) / (x² + 3)

Combine back into one fraction:

(A (x² + 3) + (Bx + C) x) / (x (x² + 3))

Now equate this numerator with the original:

A (x² + 3) + (Bx + C) x = x − 3

Ax² + 3A + Bx² + Cx = x − 3

(A + B) x² + Cx + 3A = x − 3

Match the coefficients:

A + B = 0

C = 1

3A = -3

Solve:

A = -1

B = 1

C = 1

Therefore, the partial fraction decomposition is:

-1 / x + (x + 1) / (x² + 3)

Here's a graph showing that the two are the same:

Solve the simultaneous equation :<br><br> 4x+2y=17<br> 3x+2y=14

enot [183]

Answer:

(x, y) = (3, 5/2)

Step-by-step explanation:

$4x+2y=17\\3x+2y=14$

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

$4x+2y=17\\-(3x+2y=14)$

Now just add those from top to bottom.

$\rightarrow (4x-3x)+(2y-2y)=17-14\\\rightarrow x=3$

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

$4x+2y=17\\\rightarrow 4(3)+2y=17\\\rightarrow 12+2y=17\\\rightarrow 2y=5\\\rightarrow y=\frac{5}{2}$

(x, y) = (3, 5/2)
