Answer:
No the ratio 3:4 is not equal to 4:5
Step-by-step explanation:
3:4 = 3/4 and 4:5 = 4/5
3/4 is equal to 0.75 and 4/5 is equal to 0.8
0.75 
0.8
therefore, 3:4 4:5
Hope this helps!
notice your "a" and "b" components, to get the distance "c" from the center to either foci and the vertices, of course, are h + a, k and h - a, k
Add 11 and 7
11 + 7
18
Mulitply 1/3 and 18
1/3 * 18
6
1/3 the sum of 7 and 11 is 6.
Answer:
The expectation and variance for the number of 1s in the sequence of die rolls is: 1/6
If the coin was unfair the change is: 1/2
The probability of obtainig heads was: 51%
Step-by-step explanation:
In probability and statistics theory:
The expectation and variance possibilities gotten rolling one dice are six.
In independent Bernoulli trials sequence with probability 1/2 of success on each trial is metaphorically called a fair coin.
By the other hand if the probability is not 1/2, it is called a biased or unfair coin.
It might be thought that the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails but if it starts out as heads, there's a 51% chance that it will end as heads.
The answer is 65 you are welcome
