Answer:
0.3667 or 36.67%
Step-by-step explanation:
The probability of getting at least 1 defective hard disk among the 5 (P(X>0)) is equal to 100% minus the probability of getting none defectives (1-P(X=0)).
If 23 out of 25 hard disks are non-defective, the probability is:
The probability that there is at least 1 defective hard disk is 0.3667 or 36.67%.
Answer:
1.98
Step-by-step explanation:
The triangle in the figure is a right triangle, which has a 90 degrees angle.
The side opposite to the right angle is called hypothenuse, and it is the longest side of the triangle.
For a right triangle, the following relationship exists between angles and sides:
(1)
where 
is any of the other 2 angles in the triangle, and opposite means "side opposite to the angle" and adjacent means "side adjacent to the angle".
In this problem, we know that the angle at D is
We also know that the hypothenuse is
Therefore, in order to measure EF, we can use eq.(1). We find:
Answer:
Step-by-step explanation:
85+x+x=89
85+2x=89
2x=89-85
2x=4
x=2
So she would need 89+2=91
Brand X costs $1.56 for 12 ounces
Brand X: cost of each ounce = $1.56 / 12 = $0.13
Brand Y costs 2 cents more per ounce, so the cost of brand Y per ounce= $0.13 + $0.02 = $0.15
The cost of 15 ounces of brand Y = $0.15 x 15 = $2.25
Answer
$2.25
Answer:
The answer to your question is below
Step-by-step explanation:
Process
1.- Transform the inequality to a line
2x - y < 4
2x - y = 4
2.- Find the x and y-intercepts
If x = 0, 2(0) - y = 4
0 - y = 4
y = -4 (0, -4)
If y = 0 2x - 0 = 4
2x = 4
x = 2 (2, 0)
3.- Do not consider graphs 1 and 2 because do not go through (0, -4).
4.- The answer is graph three because of the inequality "<", we look for the shaded region below the line.
