Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825
Answer:
75 Dragons
Step-by-step explanation:
We know that the ratio is 5 dragons and 4 knights.
Now, there are 60 knights, meaning the original number of knights (4), was multiplied by 15. So, if one side is multiplied by 15, the other side must follow the same rule. So, 15 x 5 = 75.
There are 75 Dragons.
Answer:
-8 °F is 8° below
Step-by-step explanation:
it's negative 8 so its 8 below
Answer:
Add 3 to both sides, so you will have
x^2 - 8x + 13 + 3 = 3
x^2 -8x + 16 = 3
And now the left side is a perfect square trinolmial: (x-4)^2.
Step-by-step explanation:

Answer:
(a)0.0005
(b)0.2720
Step-by-step explanation:
Total Number of Transistors = 16
To find the probability that 4 selected at random are defective (or non-defective), we find the probability of the 1st, 2nd, 3rd, and 4th defective (or non-defective) items in that order, Note that the selection is without replacement.
(a)Probability that all are defective
Number of Defective Transistors =4
P(all are defective)
=0.0005
(b)Probability that none are defective
Number of Non-Defective Transistors =16-4=12
P(none are defective)
=0.2720
