If WXWZ, which of the following statements CANNOT be true?
Answers
Answer:
B.
Step-by-step explanation:
The statement that cannot be true is "length RW is a mid segment of the triangle". option D.
What is mid segment of a triangle?The mid segment of a triangle is a line segment that connects the midpoints of two sides of a triangle. More specifically, if a triangle has sides of lengths a, b, and c, then the mid segment connects the midpoints of the two sides of length a and is parallel to the side of length c. The length of the mid segment is half the length of the third side (c/2).
here, we have,
In other words, if a triangle has sides AB, BC, and AC, then the mid segment connects the midpoint of AB (denoted as M) to the midpoint of BC (denoted as N) and is parallel to AC.
The length of the mid segment MN is equal to half the length of AC
(MN = 1/2 * AC).
we have,
For the given diagram, the midpoint is S, so the length RW cannot be the length of the mid segment.
Hence, The statement that cannot be true is "length RW is a mid segment of the triangle". option D.

The line plot shows the number of letters in the last name of 12 children.
Answers
Answer:
The mode is 9 letters: True
The median is 7.5 letters: True
The mean is 7 letters: False
The graph is skewed right with an outlier of 2: False
Step-by-step explanation:
1) The mode is 9 letters. (True)
The mode is the value that shows up the most. 9 letters shows up the most as the length of a child's last name.
2) The median is 7.5 letters. (True)
The median is one of the middle points of a data set. This can be found by writing out all of the results from least to greatest, and crossing out each number starting from the ends.
2, 6, 6, 7, 7, 7, 8, 8, 9, 9, 9, 9
Once you meet in the middle, you should be left with 7 and 8. In this case, we find the mean of the two numbers, which is 7.5. (In cases where the data set has an odd amount - if there were 13 children instead of 12), you'd just use the middle piece of data.
3) The mean is 7 letters. (False)
The mean is also a middle point of a data set. However, this one is different. The mean can be found by adding up all of the numbers in the data set ([tex]2+6+6+7+7+7+8+8+9+9+9+9[/tex]) and then dividing that number by the amount of numbers are in the data set. Setting this up as an expression would look like: [tex]\frac{2+6+6+7+7+7+8+8+9+9+9+9}{12}[/tex]. By plugging this into a calculator you'd get 7.25 instead of just 7.
4) The graph is skewed right with an outlier of 2.
Although the outlier of 2 part of the statement is correct, the graph is not skewed right; it is skewed left.
Given that the triangle ABC is at A=(-1,5) B=(1, 1) C = (2, 3), and if the triangle is
reflected across the line x = 4, find the new position of point C'.
Answers
Answer: (6,3)
Step-by-step explanation:
Since C is 2 units from the line of reflection, and it lies on the left of the line of reflection, C' will lie 2 units to the right of the line of reflection.
Therefore, C'=(6,3).
If Toni wants to grow flowers in her garden, she will need a special type of top soil. If she wants the topsoil to be 1 foot deep, how much topsoil is needed? Remember, the length of the garden is 44 feet and the width is 2 feet.
Answers
Answer:
Depending on the unit your answer needs to be in, it would be 88 cubic feet or 3.25926 cubic yards
If your question asks you to round to the nearest hundredth it would be 3.26 cubic yards.
Step-by-step explanation:
To find the volume of soil:
Volume= Length x Width x Depth/Height
Volume= 44ft x 2ft x 1ft
Volume= 88 cubic feet or 3.25926 (there are 27 cubic feet in a cubic yard, 88/27=3.25926)

A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures. Historically, the failure rate for LED light bulbs that the company manufactures is 3%. Suppose a random sample of 10 LED light bulbs is selected. What is the probability that:
a. None of the LED light bulbs are defective?
b. Exactly one of the LED light bulbs is defective?
c. Two or fewer of the LED light bulbs are defective?
d. What are the mean and standard deviation of the binomial distribution for the number of defective LED light bulbs?
Answers
Answer:
a) There is a 59.87% probability that none of the LED light bulbs are defective.
b) There is a 31.51% probability that exactly one of the light bulbs is defective.
c) There is a 98.84% probability that two or fewer of the LED light bulbs are defective.
d) There is a 100% probability that three or more of the LED light bulbs are not defective.Step-by-step

Answer:
a. 1/20, 1 out of twenty, or 5%
b. three out of ten, 3/10, 30%
c. 3/20 = 3/20 yes.
Step-by-step explanation:
a. It is a fraction. out of the 20 divisions there is only one 20. so there is 1 out of twenty which as a fraction is 1/20. this is equal to 1 divided by 20 wich eqauls 0.05. You move the decimal to the right twice to get 5%.
b. 6 out of twenty, 6/20. They are both even so it can be simplified.
6 ÷ 2 = 3
20 ÷ 2 = 10
It becomes 3/10, 0.3 or 30%
c. I decided that 3, 17, 2, 15, 10, and 9 are the lower right region.
the odds are 6/20 wich we know is 3/10
I only see 20 hits, but out of the 20, 6 are in the lower right region.
the odds from this is 6/20 which we know is 3/10.
We can see that the odds are equal.
What are the domain and range of the function represented by the set of ordered pairs?

A. Domain: {-6, -3, 1, 14}

B. Domain: -6 ≤ x ≤ 14
Range: -4 ≤ y ≤ 12
C. Domain: {-4, -2, 0, 12}
Range: {-6, -3, 1, 14}
D. Domain: -4 ≤ x ≤ 12
Range: -6 ≤ y ≤ 14
Answers
Answer:
A
Step-by-step explanation:
the domain is the definition of the valid x (input) values.
the range is the definition of the valid y (result) values.
as the function is defined by listing the specific points, the function only consists of individual points and not of connecting lines.
therefore the domain and range cannot be continuous intervals (otherwise the function would suddenly also include points not in the original list).
so, B and D are wrong.
and A is right, because the domain contains the x values, and the range the y values.
What is the equation of the line that is perpendicular to the line and passes through the point (15,-5)?
Answers
The equation of the line that is perpendicular to the line and passes through the point (15,-5) is y = -x + 10
The complete question is
What is the y-intercept of the equation of the line that is perpendicular to the line y = x + 10 and passes through the point (15, –5)?
What is the meaning of Perpendicular ?A perpendicular means a line which intersects the other line at 90 degree.
Line given y = x+10
slope = 1
Slope of the line perpendicular to the above line = -1
and it passes through the point (15, –5)
The equation will become
y = mx +c
-5 = -1 * 15 + c
15-5 = c
c = 10
Therefore the equation is y = -x +10

Two triangles are similar. The base of one is 2 inches and the height is 5 inches. If the base of the other is 7 inches, what is the height?
Answers
Step-by-step explanation:
similar shapes means that they have the same angles, and there is one scale factor that applies to all sides and other lines in the shapes (like heights).
therefore the ratios between 2 correlated lines are all the same.
so,
2/7 = 5/height
2×height / 7 = 5
2×height = 7×5 = 35
height = 35/2 = 17.5 in
