If one of the 50 states is chosen at random, then a standard die is rolled, Find the probability of getting a state that starts

Black_prince [1.1K]

Answer:

The final answer is 2/15 or 0.133

Step-by-step explanation:

The US States that start with an "N" are:

Nebraska
Nevada
New Hampshire
New Jersey
New Mexico
New York
North Carolina
North Dakota

The probability of selecting a state that starts with an N is 8/50

The probability of rolling at least a two is 5/6.

If we multiply the two probabilities together, we get 2/15.

Identify the zeros of the function f(x) = 2x^2 − 4x + 5 using the Quadratic Formula

Nostrana [21]

For this case we have that by definition, the roots, or also called zeros, of the quadratic function are those values of x for which the expression is 0.

Then, we must find the roots of:

$2x ^ 2-4x + 5 = 0$

Where:

$a = 2\\b = -4\\c = 5$

We have to: $x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}$

Substituting we have:

$x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (2) (5)}} {2 (2)}\\x = \frac {4 \pm \sqrt {16-40}} {4}\\x = \frac {4 \pm \sqrt {-24}} {4}$

By definition we have to:

$i ^ 2 = -1$

So:

$x = \frac {4 \pm \sqrt {24i ^ 2}} {4}\\x = \frac {4 \pm i \sqrt {24}} {4}\\x = \frac {4 \pm i \sqrt {2 ^ 2 * 6}} {4}\\x = \frac {4 \pm 2i \sqrt {6}} {4}\\x = \frac {2 \pm i \sqrt {6}} {2}$

Thus, we have two roots:

$x_ {1} = \frac {2 + i \sqrt {6}} {2}\\x_ {2} = \frac {2-i \sqrt {6}} {2}$

Answer:

$x_ {1} = \frac {2 + i \sqrt {6}} {2}\\x_ {2} = \frac {2-i \sqrt {6}} {2}$

Can u help me here I have more the next one is part 2 for this question

Harlamova29_29 [7]

The circumference of the vase is 18.84 inches.

<u>Step-by-step explanation:</u>

The circumference of the cylinder is same as the circumference of its base.

Moreover, the base of the cylinder is actually a circle.

So we need to find the circumference of the circle to find the circumference of the cylinder.

From the given figure, we know that the diameter of the base d= 6 inches.

∴The formula for the circumference of the circle = 2πr or dπ.

⇒ circumference = 6×3.14.

= 18.84.

So the circumference of the circle is 18.84 inches.

∴The circumference of the cylindrical vase is also 18.84 inches.
