She will need a minimum of 38 hours, at 38 hours she will make 456, plus the 300 she already has, so that in total is 756.
Answer:
648 inches squared or 54 feet squared
Step-by-step explanation:
12*9=108
108*6=648
684/12=54
Answer:
x = 100
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
52 + 28 + x = 180
80 + x = 180 ( subtract 80 from both sides )
x = 100
<span>x^2-2x-3=0
(x-3)(x+1)=0 [factor]
x-3=0 [set each factor equal to zero and solve for the x-value]
x=3
and
x+1=0
x=-1
So, the solutions are x = 3 and x = -1</span>
Answer:
Required Probability = 0.605
Step-by-step explanation:
Let Probability of people actually having predisposition, P(PD) = 0.03
Probability of people not having predisposition, P(PD') = 1 - 0.03 = 0.97
Let PR = event that result are positive
Probability that the test is positive when a person actually has the predisposition, P(PR/PD) = 0.99
Probability that the test is positive when a person actually does not have the predisposition, P(PR/PD') = 1 - 0.98 = 0.02
So, probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition = P(PD/PR)
Using Bayes' Theorem to calculate above probability;
P(PD/PR) =
= = = 0.605 .
