X³ + 3x² = 25x + 75
x³ + 3x² - 25x - 75 = 0
x²(x + 3) - 25(x + 3) = 0
(x² - 25) * (x + 3) = 0
(x² - 25) = 0 (x + 3) = 0
x² = 25 x = -3
x = ±5
Hope this helps! :)
Answer:
0.4
Step-by-step explanation:
Given that:
P(debt) = P(D) = Probability of being in debt = 0.7
P(debt n Midwest) = P(Dn M) = probability of being in debt and lives in Midwest = 0.280
The probability that a randomly selected farmer lives in the Midwest given that he is in debt is?
P(M | D) = p(D n M) / p(D)
P(M | D) = 0.280 / 0.7
P(M | D) = 0.4
B + 4b = 8
You have to combine the like terms and then divide both sides by the coefficient to isolate the variable b.
<em>b + 4b = 8
</em>5b = 8
(5b / 5) = 8 / 5
b = 1.6
Since it says to round to the nearest hundredth, I would just put a zero right after the tenths place.
b = 1.60
The answer is the following: 800,000
Answer:
The no. of student failed is 36.
Step-by-step explanation:
Given, the number of student enrolled= 216
Let us suppose number of student failed = x
Given,
no. of student passed is 5 times no. of student failed.
Then, no. of student passed = 5x
x +5x = 216
6x = 216
x = 216/6
x = 36
Thus, the no. of student failed is 36.
