Answer:
5 - 8 = -3
4 x -3 = -12
2 + -12 = -10
Step-by-step explanation:
Y=mx+b...............................................................................................
To solve for the quadratic equation 9x² = 4, we need to recall that the difference between two square can be expressed as the product of their sum and difference or (a² - b²) = (a + b)(a - b).
Thus, we have
9x² = 4
9x² - 4 = 0
(3x)² - (2)² = 0
(3x + 2)(3x - 2) = 0
We now have two linear equations:
3x + 2 = 0 | 3x - 2 = 0
3x = -2 | 3x = 2
x = -2/3 | x = 2/3
Thus, x = +2/3 and -2/3.<span>

Answer:
Step-by-step explanation:
Given that in an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are run.
No of 5's Freq Prob
0 6 0.1
1 9 0.15
0 33 0.55
3 3 0.05
4 9 0.15
60 1
The above is the probability distribution of the discrete variable.
