Answer:

? = 9

Step-by-step explanation:

The segments of each of the transversals are proportional. On the left side, the bottom transversal segment will be 10 -6 = 4 units in length.

Now we can write a proportion relating right-side transversal segments to left-side transversal segments:

?/6 = 6/4

? = 6(6/4) = 36/4 = 9

The missing length is 9 units.

Anyone know how to work this out?

The first and crucial thing we want to take notice is that the lines DF and EG intersect at point H which creates 4 different triangles in the rhombus. The innermost angles of DGH and EFH are vertical angles and vertical angles are congruent. So if the angles of the triangles are congruent than the triangles themselves are congruent. This is supported by the vertical angles theorem.

Solve for a and x in ax^2=48<br>

Gelneren [198K]

Answer:

$ax^2 = 48\\a = \frac{48}{x^2}$

$ax^2 = 48\\x^2 = \frac{48}{a} \\x = \frac{\sqrt{48} }{\sqrt{a} } \\x = \frac{4\sqrt{3} }{\sqrt{a}} \\x = \frac{4\sqrt{3a} }{a}$

5. A box in a supply room contains 15 compact fluorescent lightbulbs, of which 5 are rated 13-watt, 6 are rated 18-watt, and 4 a

skelet666 [1.2K]

Answer:

176/1125 or 0.156

Step-by-step explanation:

There are 15 bulbs, of which 4 are 23-watt. The probability of selecting a 23-watt bulb = 4/15. If we call this probability x, then x = 4/15.

The probability of selecting a 13-watt or 18-watt bulb is the probability of not selecting a 23-watt bulb. If we call this y, y = (6+5)/15 = 11/15. It follows that x and y are mutually exclusive. Here, we have a binomial distribution.

The number of ways of selecting exactly two 23-watt bulbs out of three is

$\binom{3}{2} = 3$

The probability of selecting them is

$3x^2y = 3\times\left(\dfrac{4}{15}\right)^2\times\dfrac{11}{15}=\dfrac{176}{1125}= 0.156$
