We have a base 2 with an exponent power raised to -3
so in order to have a positive exponent factor, we take reciprocal of the number1/2^3.
now that the base has a positive exponent number, we simply multiply it the times on the exponent number, so: 1/2*2*2 = 1/8
hope this help

.we have PE congruent to ER
.angle PEF congruent to angle FER
.and EF that is common for both of triangles
6.SSS
.MO congruent to KL
.MK congruent to OL
.KO that is common for both of triangles.
$308 bc i added 250+30 = 280 and multiplied it by 0.10 to get 28 and i added that to 280
Using proportions, it is found that there is a 0.54 = 54% probability that a randomly selected household owns a cat.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the proportions associated with owning a cat are given by:
- 70% of 60%(also have a dog).
- 30% of 40%(do not have a dog).
Hence:
p = 0.7(0.6) + 0.3(0.4) = 0.42 + 0.12 = 0.54.
0.54 = 54% probability that a randomly selected household owns a cat.
