A. 16x11 = 176 + 30x8.75 = 262.5. 176+262.5 = 438.5. Not 470
B. 20x11 = 220 + 26x8.75 = 227.5. 220+227.5 = 448. Not 470
C. 30x11 = 330 + 16x8.75 = 140. 330+140 = 470. C. is the correct answer
D. 31x11 = 341 + 15x8.75 = 131.25. 341+131.25 = 472.25 Not 470
Answer:
x = 0
y = 5
z = -5.
Step-by-step explanation:
X-5y-z=-20
-2x-y-6z=25
-x-4y-z=-15
Add equation 1 and 3:
-9y - 2z = -35 .......... A
Multiply the first equation by 2:
2x - 10y - 2z = -40
Now add this to equation 2:
-11y -8z = -15.............B
Now multiply equation A by -4:
36y + 8x = 140.........C
Add equations B and C:
25y = 125
y = 5.
Substitute for y in equation A:
-9*5 - 2z = -35
2z = -45 + 35 = - 10
z = -5.
Now find x by substituting for y and z in the first equation:
x - 5(5) - (-5) = -20
x - 20 = -20
x = 0.
Answer:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.
Step-by-step explanation:
For each part, there are only two possible outcomes. Either they are defective, or they are not. Each part has a 4% probability of being defective, and the probability of a part being defective is independent of other parts, that is, they are selected independently. These are the conditions under which this situation would be a binomial experiment.
So the correct answers are:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.
The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.
Step-by-step explanation:
The given is,
Two points are L=(1,-3) and P=(8,-7)
Step:1
By graphical method,
First point L (1,-3)
The values of x=1 and y=-3 noted in the graph
Second point P(8, -7)
The values of x=8 and y=-7 noted in the graph
Now join the points L and P, in the graph,
Distance between two points are 8.1 units
( OR )
Step:2
By formula method,
Distance =
Where,
L (1,-3) are ()
P (8,-7) are ()
Substitute the values,
=
=
=
=
Distance = 8.06225 units
Result:
The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.
