Answer:
The probability that the bulb will last more than 1,200 hours is 0.3012
Step-by-step explanation:
Let the random variable <em>X</em> = life of a light bulb .
The random variable
The probability distribution function of exponential distribution is:
The mean of the distribution is, Mean = 1000 hours.
The value of λ is:
Compute the probability that the bulb will last more than 1,200 hours as follows:
Thus, the probability that the bulb will last more than 1,200 hours is 0.3012.
The answer for this question is= 46.5
What is 155 percent of 30 is 46.5.
It's all from the knowledge.
Left side:
x+x+x+1+1+1+1+1+1+1+1 = 3x + 8
Right side:
x+x+x+x++1+1+1+1+1+1
Left side = Right side to solve x
3x + 8 = 4x + 6
Subtract 4x from both sides
3x + 8 - 4x = 4x + 6 - 4x
Simplify
-x + 8 = 6
Subtract 8 from both sides
-x + 8 - 8 = 6 - 8
Simplify
-x = -2
Multiply both sides by (-1)
-x * (-1) = -2 * (-1)
Simplify
x = 2
Answer
C. x = 2
CD is the perpendicular bisector of another line AB which can be proven below.
<h3>What is perpendicular bisector?</h3>
Perpendicular bisector is a line that divides another line into two equal halves in such a way that it creates an angel of 90°.
To proof that CD is the perpendicular bisector of another line AB the following is carried out;
- Draw a line segment AB with length of about 5 cm.
- With any radius greater than 2.5 cm, and compass fixed at A, draw 2 arcs, one above and one below AB.
- With the same radius, compass at B, cut the 2 arcs drawn in step 2.
- The line joining these two arcs is the perpendicular bisector of AB.

Answer:
c=-0.98
Step-by-step explanation:
We know that the function
is solution of the differential equation
to find the value of c we use the condition y(10)=2
then, c = -0.98
hope this helps!!
