For Part A the probability is 0.0095 and for Part B the probability is
0.0043.
What does defective mean in probability?Probability of defect is perhaps the most important indicator of a manufacturing process's quality. It's a statistical technique used to indicate how often a product will fail during its lifespan, which in turn allows you to estimate the likelihood that an item will result in customer dissatisfaction.
Part A:
The number of rivets=22 rivets
Probability that no rivet is defective= [tex](1-p)^{22}[/tex]
The probability that at least one rivet is defective=1-[tex](1-p)^{22}[/tex]
For 19% of all seams need reworking, probability that a rivet is defective is given by
1-[tex](1-p)^{22}[/tex] = 0.19
[tex](1-p)^{22} = 1-0.19\\(1-p)^{22} = 0.81\\ p=1-\sqrt[22]{0.81} \\p=0.0095[/tex]
Part B:
For 9% of all seams need reworking, probability of a defective rivet is:
1-[tex](1-p)^{22}[/tex] = 0.09
[tex](1-p)^{22} = 1-0.09\\(1-p)^{22} = 0.91\\ p=1-\sqrt[22]{0.91} \\p=0.0043[/tex]
Hence, For Part A the probability is 0.0095 and for Part B the probability is 0.0043.

If ABC is reflected across the y-axis, what are the coordinates of C?
A. (6,-3)
B. (3,-6)
C. (-6,-3)
D. (-6,3)
Answer:
Step-by-step explanation:
The correct answer would be C (-6,3). The y axis is the bold line going up and down on the middle of the page. If you were able to pick up triangle and flip it over the y axis. Point C would land at (-6,3).
Also, you can see that point C is six spaces to the right of the y axis. That means when we flipped it over the axis, it will now be six paces to the right of the y axis. Since the point did not go up or down when you flipped it. It is still 3 spaces above the x axis.
Answer:
D (-6, 3)
Step-by-step explanation:
the point C is originally (6, 3).
that means the x coordinate is 6, the y coordinate is 3.
now, if we reflect (= mirror) that point across the y axis, that means we mirror it to the other side of the y axis.
the y axis is the vertical coordinate axis in the middle of the graph.
so, what is going to happen to the point ?
will the y coordinate change ? no. the point will move over to the other side of the y line in the same "height" as before. nothing will move it higher or lower.
so, it will keep the same y coordinate : 3.
will the x coordinate change ? oh, yes. because the point will move from the right of the y axis to the left of the y axis. and it will be the same distance to the left as it was originally to the right.
so, +6 turns into -6 (as the y axis represents x=0).
In the Michigan lottery game, LOTTO 47, the state selects six balls randomly out of 47 numbered balls. The player selects six different numbers out of the first 47 positive integers. Prizes are given for matching all six numbers in any order (the jackpot) and matching five numbers ($2500). A ticket costs $1.00 and this dollar is not returned to the player. Find the probabilities of matching
The probability of matching six numbers is [tex]\frac{1}{47C_{6}}[/tex].
How to find the probability of matching six numbers?To find the probability, we have to divide the favorable events by the total number of events.
The total number of events is given by:
[tex]47C_{6}[/tex]
We use combinations since the order doesn't matter.
The total number of favorable events is given by:
[tex]6C_{6}[/tex]
The probability is given by:
[tex]\frac{\text{Favorable events}}{\text{Total events}}=\frac{6C_{6}}{47C_{6}} \\= \frac{1}{47C_{6}}[/tex]
We have found the probability of matching all six balls to be [tex]\frac{1}{47C_{6}}[/tex].

3a) The coordinate of R after dilation is; R' = (-6, 21)
3b) The coordinate of T after dilation is; T' = (1, 3)
5) A dilation by a scale factor of 2 followed by a translation right 1 up 3.
How to carry out dilation in Transformation?3a) We are given the coordinates of the rectangle as;
Q(-2, -1), R(-2, 7), S(4, 7), T(4, -1)
Now, we are told that R(-2, 7) is dilated about the origin with a scale factor of 3. Thus;
R' = (-2 *3), (3 * 7)
R' = (-6, 21)
3b) We are now told that T(4, -1) is dilated by a scale factor of 1/2 with R as center of origin. R has a coordinate of (-2, 7). Thus;
Coordinate of T' = (-2, 7) + ¹/₂((4, -1) - (-2, 7))
Coordinate of T' = (-2, 7) + ¹/₂(6, -8)
Coordinate of T' = (-2, 7) + (3, -4)
Coordinate of T' = (1, 3)
5) We can see that LN is 2 units while L'N' is 4 units and so we can say scale factor in the transformation of ΔLMN to ΔL'M'N' is 2.
Now, if we apply scale factor of 2 to coordinates of N before transformation, we will have; 2(3, 1) = (6, 2)
Comparing to N' which is (5, 5) we can say that it was shifted up by 3 units and right by 1 unit.

The frequency table displays the number of ill patients in each age group. The first two plots are incorrect because the sum of the dots connecting the numbers 24, 25, 26, 27, 28, and 29 in the first two plots is 3, but not in the other two plots.
In conclusion, there are only 4 ill individuals when the dots from the 30-34 age range on the first plot are added together. There are a total of 6 cases in that age group on the second graph. As a result, the second dot plot is the one that matches the frequency table.

Both systems have an infinite number of solutions.
The system of equations has more solutions.
The system of inequalities has more solutions.
Both systems have only one solution.
we conclude that the system of inequalities has more solutions than the system of equations.
What can we conclude about the two given systems?We have the system of equations:
y = (-1/2)*x + 1
y = x - 5
And the system of inequalities:
y > (-1/2)*x + 1
y < x - 5
First, if you look at the first system you can see that we have two non-parallel lines, so that system has only one solution.
Now let's look at the system of inequalities, we can get solutions like:
x = 10
y = 1
1 > (-1/2)*10 + 1 = -4
1 < 10 - 5 = 5
So both inequalities are true, which means that the point (10, 1) is a solution.

It takes 165 minutes per week if 10% increase in volume for an exercising client.
How much is the 10% increase in the volume?A client is exercising for 150 minutes per week. I.e., 30 minutes, 5 days per week.
So, 10% increase results,
