Answer:
The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Step-by-step explanation:
9x² - 4x + 1 = 0 ax² + bx + c = 0
The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20
b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Answer:
$55.80
Step-by-step explanation:
8, 16, 24, 32, 36
8=12.40, 16=24.80, 24=37.2, 32=49.6,
+4 makes it 36 so it's have of 8, so add 6.20 to the end and it's 55.80
Answer:
C) -3
Step-by-step explanation:
Rearrange your equation so that it is in slope-intercept form (y = mx + b). The m in the equation is the gradient.
y = 7 - 3x
y = -3x + 7
The m-value is -3. This means that the gradient is -3.
Answer:
11/25 The right answer is not a part of the options given.
Step-by-step explanation:
Given;
Probability that event M will not occur = 0.8
Probability that event R will not occur = 0.6
Then the ;
Probability that event M will occur = 1 - 0.8 = 0.2
Probability that event R will occur = 1 - 0.6 = 0.4
If events M and R cannot both occur, probability that either event M or event R will occur
= probability that M occurs and R does not or the probability that R occurs and M does not
= 0.2 × 0.6 + 0.4 × 0.8
= 0.12 + 0.32
= 0.44
= 11/25
