Answer:
Step-by-step explanation:
a=213
l=912
let cardinal number=n
let c.d.=d
d=214-213=1
l=a+(n-1)d
912=213+(n-1)1
912=213+n-1
912-212=n
n=700

U = {1,2,3,4,5,6,7,8,9},
A = {1,2,3,4,5,6},

A∩B = {2,4,5,6,}
A∪C = {1,2,3,4,5,6,7}
(AUB)∩(A∪C) = {1,2,3,4,5,6}
A'∩B' ={7,8,9}
(A∩C)' = {2,3,4,5,7,8,9}
A∪C = {1,2,3,4,5,6,7}
A∩(B∪C) = {1,2,4,5,6}
A' = {7,8,9}
A'∪B' = {1,3,7,8,9}
A-B = {2,4,5,6}
A∪B = {1,2,3,4,5,6}
A∪(B∪C) = {1,2,3,4,5,6,7}

Which of the dot plots shows a symmetric distribution?
The dot plot that has a symmetric distribution is option b.
What is a dot plot?A dot plot is a graph that has similarities with a histogram. A dot plot is made up of a number line and dots. A dot plot is used to represent the frequency of a data set.
The dots in the dot plot represent the frequency of the data. The greater the frequency of a data, the greater the number of dots the number has. For example, if a number has a frequency of 6, it would have 6 dots have it.
A dot plot is symmetric if the left side of the graph and the right side of the graph are mirror images of each other. A dot plot is skewed to the left if there are more dots on the left side of the graph. A dot plot is skewed to the right if there are more dots on the right side of the graph.

f(x)=4x^2-x-3, find x when f(x)= -3
Answer:
x = 0 or x = 1/4
Step-by-step explanation:
f(x) = 4x^2-x-3 = -3
4x^2 - x - 3 = -3
4x^2 - x = 0
x(4x - 1) = 0
x = 0 or 4x - 1 = 0
x = 0 or x = 1/4
Answer:
The values for x are x =0 x = 1/4
Step-by-step explanation:
f(x)=4x^2-x-3
find f(x) = -3
Let f(x) = -3
Solve for x
-3 = 4x^2-x-3
Add 3 to each side
-3+3 = 4x^2-x-3+3
0 = 4x^2-x
Factor out an x
0 = x( 4x-1)
Using the zero product property
0 = x 4x-1 =0
0=x 4x=1
0=x x = 1/4
The values for x are x =0 x = 1/4

Which inequality correctly compares 5/6,1/2,3/9
and 1?
The inequality between (5/6), (1/2), (3/9) and 1 can be best described by
[tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].
As per the question statement, we are provided with three proper fractions, (5/6), (1/2), (3/9) and an integer, 1.
We are required to correctly compare the inequality between the question mentioned terms.
Since all three fractions are proper fractions, i.e., their numerators are less than their denominators, hence, all three fractions are less than the integer 1.
Thus, we are required to determine the order of magnitude between the fractions. To do so, we will calculate the L.C.M of the denominators.
L.C.M of 2, 6 and 9 is 18.
Therefore, we will multiply both the numerator and denominators of (5/6) with 3, and we will obtain [tex]\frac{5*3}{6*3} =\frac{15}{18}[/tex].
Similarly, we will multiply both the numerator and denominators of (1/2) with 9, and we will obtain [tex]\frac{1*9}{2*} =\frac{9}{18}[/tex].
Finally, we will multiply both the numerator and denominators of (3/9) with 2, and we will obtain [tex]\frac{3*2}{9*2} =\frac{6}{18}[/tex].
Now comparing [tex][\frac{15}{18}, \frac{9}{18}, \frac{6}{18}],[/tex] we can see than all the denominators are now same (18). Hence, the order of magnitude of the fractions can be determined in the order of magnitude of the numerator values, i.e.,
[15 > 9 > 6] or, [6 < 9 < 15].
Therefore, [tex][\frac{6}{18} < \frac{9}{18} < \frac{15}{18}][/tex], or, [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6}][/tex].
And since 1 is greater than any proper fraction, The inequality between (5/6), (1/2), (3/9) and 1 can be best described by [tex][\frac{3}{9} < \frac{1}{2} < \frac{5}{6} < 1][/tex].
