Answer:

The correct answer will be "-1.66".

Step-by-step explanation:

Let z₀ be,

$P(z$

$=0.048$

⇒ $\Phi (z_0)=0.048$

Now,

⇒ $\Phi (-1.6646)=0.048$

$z_0=-1.6646$

$\simeq -1.66$

Thus the above is the right answer.

Find the measure of an interior angle and exterior angle of a regular 24gon

Julli [10]

Answer:

Interior Angle: 165°

Exterior Angle: 15°

Step-by-step explanation:

So first you have to find the sum of all interior angles of a polygon with 24 sides. This can be found using the formula:

sum = ( n - 2 ) * 180° where 'n' is the number of sides.

When 'n = 24' then the sum is:

sum = ( 24 - 2 ) * 180°

Simplify and solve.

sum = 22 * 180°

sum = 3960°

Since there are 24 sides to the polygon, there are 24 interior angles. Assuming that this polygon is equilateral, you can surmise that:

Interior Angle = sum° / n where n is the number of sides,

3960° / 24 = 165° = Interior Angle

Using that information, and combine it with the [Supplementary Angles Theorem] the exterior angle can be found by:

165° + x = 180°

Solve for x.

Let's call the aces $h, d, c, s$ for hearts, diamonds, clubs and spades. So, $h, d$ are red and [ted] c, s[/tex] are black.

Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple

$(x,y)\, x, y \in \{h,d,c,s\}$

There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favour to deduce the probability of winning:

If we want a player to draw two card of the same colour, the following couples are good:

$(h,h),\ (h,d),\ (d,h),\ (d,d),\ (c,c),\ (c,s),\ (s,c),\ (s,s)$

so 8 possible couples over 16. This means that the probability that a player draws two cards of the same color is 8/16 = 1/2.

Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:

$(h,c),\ (h,s),\ (d,c),\ (d,s)$

which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.

The price of a technology stock was $9.71 yesterday today the price rose to $9.84 find the percentage increase round your answer

VARVARA [1.3K]

Answer:

1.34%

Step-by-step explanation:

In order to find the percentage increase between these two prices, we must first find the difference in price. We calculate this by subtracting the final price by the initial price like so...

$9.84 - 9.71 = 0.13

Now we divide the difference by the initial price to find what percentage of the initial price this difference is, since this percentage difference was added to the initial price to get the new and final price point.

0.13 / 9.71 = 0.013388 ... multiply by 100 to get percent value

0.013388 * 100 = 1.3388% or 1.34% rounded.
