Arrange in ascending order:
0, 0, 0, 1, 1, 1, 2, 2, 3, 4, 8, 8, 9.
The median = middle value = 2.
Lower quartile = 0.5
Upper quartile = 6.
what’s the circumference, to this problem ?
Answer:
9.42 i think
Step-by-step explanation:
Answer:
The formula to get the circumference of a circle is [tex]C=2*\pi * r[/tex] but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this [tex]C=d*\pi[/tex].
We can then input the value and we get that [tex]C=3*\pi[/tex] which then just narrows down to [tex]C=9.425[/tex].

The multiplication of two rational numbers results in a _____________
===========================================================
Explanation:
The proof of this is as follows
p, q, r and s are integers
q and s cannot be zero
A = some rational number = p/q
B = some other rational number = r/s
A*B = (p/q)*(r/s) = (p*q)/(r*s)
The result is of some form integer/integer, where the denominator is nonzero. This shows that A*B is rational.
Therefore,
rational*rational = rational

A few examples:
(1/2)*(3/7) = (1*3)/(2*7) = 3/14(2/5)*(9/8) = (2*9)/(5*8) = 18/40 = 9/20(7/3)*(-1/9) = (7(-1))/(3*9) = -7/27Side note: any whole number is a rational number. For instance, the number 7 can be thought of as the fraction 7/1 or 14/2 or 21/3 and so on.

Which graph represents the solution of y > x2 + 2?
The graph that represents the solution of y>x²+2 is given below.
The given inequality is y>x²+2.
We need to identify which graph represents the solution of y>x²+2.
What is an inequality graph?Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
For example, this graph shows inequality. This can be seen as there is a dashed line, and the region where the coordinates are less than -1 is shaded.
Graph the inequality by finding the boundary line, and then shading the appropriate area.
Put x=0, 1, 2, 3,....in the inequality and solve for y.
We get y=2, 3, 6, 11,...

Answer:
I did it and got it correct
Step-by-step explanation:
Find P(B|C). P(B|C) = StartFraction 9 Over 34 EndFraction = 0. 26 P(B|C) = StartFraction 9 Over 24 EndFraction = 0. 38 P(B|C) = StartFraction 9 Over 70 EndFraction = 0. 13 P(B|C) = StartFraction 9 Over 58 EndFraction = 0. 16.
The question is an illustration of probability, and the value of P(B|C) is P(B|C) = 9/24 =0.38
How to determine the probability P(B|C)?The table is given as:
C D Total
A 15 21 36
B 9 25 34
Total 24 46 70
The probability (BIC) is calculated using:
P(B|C) = n(B and C)/n(C)
From the table, we have:
n(B and C) = 9
n(C) = 24
So, the equation becomes
P(B|C) = 9/24
Evaluate
P(B|C) = 0.38
Hence, the value of P(B|C) is P(B|C) = 9/24 =0.38

What is the mean absolute deviation for the data set?
Enter your answer as a number rounded to the nearest tenth, like this: 42.5
If the mean value of the data set is 509. Then the mean absolute deviation (MAD) for the data set will be 51.5.
What is the mean absolute deviation?It is the average distance between each data point and the mean.
The mean of the following data is 509.
{419, 450, 462, 499, 520, 521, 589, 612}
Then the mean absolute deviation (MAD) for the data set will be
[tex]\rm MAD =\dfrac{1}{n}\sum_{i=1}^{n}\left|x_i - \mu \right|[/tex]
We have
μ = 509
n = 8

Suppose A< - 1 what must be true about the value of b so that ab< a
Answer:
b must be positive
Step-by-step explanation:
if a is less than -1
that means to get smaller numbers
b needs to be positive
so that when a is multiplied by b you would have
numbers that are more negative
Answer:
b > 1
Step-by-step explanation:
Given:
a < -1 ab < aSubstituting a = -1 into ab < a
⇒ (-1)b < -1
⇒ -b < -1
⇒ b > 1
If a < -1 then a is negative. If ab < a then ab is also negative.
In order for ab to be negative (when a is negative) b must be positive.
For ab < a then b > 1.
Proof
If b = 0.5 and a = -1.5 then ab = -0.75
As -0.75 > -1.5 then ab > a so this cannot be true.
If b = 1.5 and a = -1.5 then ab = -2.25
As -2.25 < -1.5 then ab < a so this is true.
Therefore b > 1
