An investor is interested in purchasing an apartment building containing six apartments. The current owner provides the followin

Vsevolod [243]

Answer:

b) 2.7632

Step-by-step explanation:

To find the mean, we multiply each value by it's probability. So

$E = 0\frac{5}{38} + 1\frac{9}{38} + 2\frac{7}{38} + 3\frac{4}{38} + 4\frac{3}{38} + 5\frac{2}{38} + 6\frac{8}{38} = \frac{1*9 + 2*7 + 3*4 + 4*3 + 5*2 + 6*8}{38} = 2.7632$

So the correct answer is:

b) 2.7632

Why does multiplying a + bi by the complex conjugate a -bi eliminate I from the expression

navik [9.2K]

<u>EXPLANATION</u>

The reason is that

$i^2=-1$

If we multiply $a+bi$ by its conjugate $a-bi$

We obtain;

$(a+bi)(a-bi)$

This is difference of two squares so we obtain;

$(a+bi)(a-bi)=a^2-(bi)^2$

This further gives us,

$(a+bi)(a-bi)=a^2-b^2i^2$

Since the $i^2=-1$ , we substite to get;

$(a+bi)(a-bi)=a^2-b^2(-1)$

The $i$ is now eliminated and we get,

$(a+bi)(a-bi)=a^2+b^2$

) If the pattern shown continues, how many black keys appear on a portable keyboard with 49 white keys? Suggestion: use equivale

andriy [413]

Answer:

35

Step-by-step explanation:

Here we see 5 black keys for every 7 white keys.

So the ratio is 5:7

If we need 49 white keys, find the amount we scale the original ratio by:

49/7 = 7

So we are scaling by a factor of 7.

The number of black keys would be 5 * the scale of 7. = 35

So there should be 35 black keys.

Three friends are playing catch. Zoe is in a straight path 12 feet to the west of alex. Jin is in a straight path 9feet to the n

Tanzania [10]

Answer:

15 ft

Step-by-step explanation:

This problem can be represented by a right angle triangle, shown in the diagram below.

The distance between Jin and Zoe is the hypotenuse of the triangle, x.

According to Pythagoras theorem,

hyp² = opp² + adj²

Where opp is the opposite side and adjacent is the adjacent side to any angle of consideration (which is not important in this case)

Hence:

x² = 12² + 9²

x² = 144 + 81

x² = 225

Finding the square root:

x = 15 ft

Jin and Zoe are 15 ft apart.
