Answer:
Option A is right
Step-by-step explanation:
In any data set, we find that the range is the difference between maximum and minimum. The range cannot give full information about the variability of the data set.
Outliers are the ones which are either below Q1-1.5IQR or Q3+1.5IQR
Thus Inter quartile range, the difference between I quartile and III quartile gives a better idea about variability and also outlier.
Hence out of the four options given, we find that option B is the right one.
Option
A. The IQR is the best measure of variability because the distribution has an outlier.
Answer: the answer is a

Peyton and James each bought a large cookie cake. The cookie cakes are
the same size.
Peyton cut his cookie cake into 12 slices.
James cut his cookie cake into 6 slices and ate 4 slices.
Together Peyton and James ate 10
12 of one cookie cake.
How many slices of cake did Peyton eat?
A 1 slice
B 2 slices
C 3 slices
D 4 slices
Answers
Answer:
2 slices.
Step-by-step explanation:
Let's say that James' cake is essentially one half of Peyton's cake. 6 x 2 is 12, and 4 x 2 is 8. So James' must have eaten 8 slices while Peyton ate 2.
Help me I am a stone when it comes to absolute value in problems—
Explination too please
Answers
Answer:
31.) you put a dot on one and go to the right
32.) you put a dot on ten and go to the left
Step-by-step explanation:
the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!
when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.
Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed
[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]
[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)
c) Is triangle DCA congruent to triangle BCA? Explain. (2 points)
Answers
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Write the equation of a line that passes through the point (–10, 2) that has a slope of .5
Answers
Answer:
y=(.5)x+7
Step-by-step explanation:
Hello. For this question, they are asking us to find the equation of a line. A line has this form: y=mx+b.
For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.
First, we can put in the point into the equation. The point given is (-10,2) so the x value is -10 and they y value is 2.
y=mx+b
2=m(-10)+b
Then we know that the slope is .5, so we can put that in as m.
2=(.5)(-10)+b
Solving for b, we get that it is equal to 7.
[2+5=b] b=7
Therefore, the equation for the line would be:
y=(.5)x+7

Explanation:
The volume of a rectangular prism (R):
length x width x height
Replacing with the values given and solving for v(Volume)
V(R) = 4x 2 x 1
V(R) = 8m3
Volume of a triangular prism (T): base area X
height
Base area = 1/2 x base × height (of the triangular base)
A = 1/2 x1x 3.5 = 1.75m2
Back with the volume formula:
V (T)= Ax h= 1.75 x 2 = 3.5m3
Adding both volumes:
8 +3.5 = 11.5 m3
