<h2>Using the quadratic formula</h2>
The quadratic formula can help us solve for x in a quadratic equation:
We can use this when the given equation is organized in standard form:
<h3>Applying this to the problem</h3>
First we can identify the values of a, b and c:
a = 2
b = 5
c = -4
Plug these values into the quadratic formula:
<h2>Answer</h2>
Therefore, the two possible values of x are:
Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:
Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
Correct question is;
A bag contains 10 counters. 6 of them are white. A counter is taken at random and not replaced. A second counter is taken out of the bag at random. Calculate the probability that only one of the two counters are white
Answer:
probability that only one of the two counters is white = 8/15
Step-by-step explanation:
To solve this question, first of all, let's look at probability we would have to either draw two white counters or two non-white counters (4/10 * 3/9).
Probability(draw 2 white counters) = (6/10 × 5/9) = 30/90 = 1/3
Probability(draw 2 non-white counters) = (4/10 × 3/9) = 2/15
Now, In all other cases, we'll draw exactly one white and one non-white counter, so the odds of this would be;
P(one white counter and one non-white counter) = 1 - [1/3 + 2/15)
= 1 - 7/15 = 8/15
$25.21 times 40 equals $1008.40 This is how much he makes a week.
1008.4 times 52 equals $52436.80
He makes $52436.80 a year.
Good evening ,
Answer:
We know that 1/2 = 0.5 then
The only values that could correctly fill in the blank are:
10% ( = 0.1 )
-0.1
1/4 ( = 0.25 ).
