Answer:
a= 25.69, b=23.12, c=131.119
Step-by-step explanation:
Whenever a quadratic equation is in the form
(i.e. the leading terms is 1), you can solve it by looking for two numbers that give when summed and when multiplied.
So, in your case,
So, we're looking for two numbers such that:
you can clearly check that these numbers are 3 and 4.
(2y + 2t − 3) dt + (8y + 2t − 1) dy = 0, y(−1) = 2.
Answer:
x=1
Step-by-step explanation:
x+y=4
replace y with 3x
x+3x=4
then add the x which is 1x plus 3x
4x=4
then divide 4 on both sides
4x/4=4/4
and your answer is 1
Answer:
A. The probability of event A
Step-by-step explanation:
The proportion of times a particular event A occurs is known as the probability of event A because the probability is the measure of uncertainty and by definition probability is calculated as
P(x)=X/n
where
P(x) is the probability of occurring of random variable X
X=number of favorable outcomes
and
n= total number of outcomes.
Thus, the proportion of times a particular event A occurs is known as the probability of event A.
