Answer:
0.33411
The probability that a particular criminal trial lasted atleast 24 days is 0.33411
Step-by-step explanation:
The random variable X is normally distributed with a mean of 21 and standard deviation of 7
;
X ~ N(μ = 21 ; σ = 7)
X ~ N(21, 7)
Probability that a trial lasted atleast 24 days :
P(X ≥ 24) :
The standardized score :
Z = (x - μ) / σ ; (24 - 21) / 7 ; 3 / 7 = 0.4286
Hence,
P(Z ≥ 0.4286) = 0.33411
The probability that a particular criminal trial lasted atleast 24 days is 0.33411

(x - 3)(x + 9) = -27
Expand the brackets:
x^2 + 9x - 3x - 27 = -27
Simplify:
x^2 + 6x - 27 = -27
+ 27 to both sides
x^2 + 6x = 0
Factorise:
x(x + 6)
The solutions are x = 0, x = -6

Answer:
48 Cubic Inches
Step-by-step explanation:
One foot, whether it be squared, cubed, or otherwise changed, will always equal twelve inches to the same power. So, 4 cubic feet is 48 cubic inches because 4*12=48
Answer:
The fraction 5/-12 will be shown as a positive number divided by a negative number, which always results in a negative amount. The fractions have different value, so Liam is not correct. [I'm assuming thats your fraction because its the same I had a few days ago]
Well the sides of these 2 quadrilaterals are proportional to each other , so you would have to find the scale factor of the 2 then see which sides have already proportional pairs , then multiply *or / to find the last one .
