1 answer:
Paladinen [302]3 years ago
6 0

Answer:

k = 3.9

Step-by-step explanation:

Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:

\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\

<u>k = 3.9</u>

Which is equivalent to 256 Superscript three-fourths? 4 12 64 192
Vaselesa [24]

Answer: 64

Step-by-step explanation:

256 is thesame thing as 2 raise to power of 8.

We then multiply 2 raise to power 8 by the power of 3/4. We will then be left with 2 raise to power 6.

2 raise to power 6 equals:

= 2 × 2 × 2 × 2 × 2 × 2

= 64

I need help please with this math problem
Arada [10]
When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.

All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.

You can check to see if the signs agree in detail. (They do.)
