Answer:
1/4¹⁰
Step-by-step explanation:
this is the the simplified version for the question
Aline read a report saying 39% of teachers in the United State were members of a labor union. She wants to test whether this holds true for teachers in her state, so she is going to take a random sample of teachers and see what percent of them are members of a union. Let p represent the proportion of teachers in her state that are members of a union. Write an appropriate set of hypotheses for her significance test.
Answer:
H0: p= 0.39 vs Ha: p ≠ 0.39
Step-by-step explanation:
She wants to test whether this holds true for teachers in her state.
The test is the formulated into the hypotheses.
The null hypothesis would be
H0: p= 0.39 against the claim Ha: p ≠ 0.39
The null hypothesis tells that the the proportion of teachers in her state that are members of a union is equal to the proportion of teachers in the US that are members of the labor union.
against the claim
That the the proportion of teachers in her state that are members of a union is not equal to the proportion of teachers in the US that are members of the labor union.
What is the mean of this set of numbers?
3, 7, 0, 3, 4, 0, 9, 1
Answer:
3.375 or 3.38 if rounded to the hundredths place.
Step-by-step explanation:
To get the mean of a set of numbers we add all the numbers in the set and then divide the sum by the amount of numbers in the set.
3+7+0+3+4+0+9+1= 27
Amount of numbers: 8
We divide 27 by 8.
27 ÷ 8= 3.375
3.375 is the mean, which we can round to 3.38 or further down to 3.4 for the tenths place and 3 for the ones place.

Mike borrowed a sum of rs 9450 for 5 years at a rate of 6% per year. calculate the total amount that he had to pay.
First year :
9450 + 9450 × ( 6 / 100 ) =
9450 + ( 9450 × 6 / 100 ) =
9450 + ( 56700 / 100 ) =
9450 + 567 =
Rs 10,017
_____________________________
Second year :
10,017 + 10,017 × ( 6 / 100 ) =
10,017 + ( 10,017 × 6 / 100 ) =
10,017 + ( 60,102 / 100 ) =
10,017 + 601.02 =
Rs 10,618.02
______________________________
Third year :
10,618.02 + 10,618.02 × ( 6 / 100 ) =
10,618.02 + ( 10,618.02 × 6 / 100 ) =
10,618.02 + ( 63,708.12 / 100 ) =
10,618.02 + 637.0812 =
Rs 11,255.1012
_______________________________
4th year :
11,255.1012 + 11,255.1012 × ( 6 / 100 ) =
11,255.1012 + ( 11,255.1012 × 6 / 100 ) =
11,255.1012 + ( 67,530.6072 / 100 ) =
11,255.1012 + 675.306072 =
Rs 11,930.407272
_______________________________
5th year :
11,930.407272 + 11,930.407272 × ( 6 / 100 )
=11,930.407272 +( 11,930.407272 × 6 / 100)
= 11,930.407272 + ( 71,582.443632 / 100 )
= 11,930.407272 + 715.82443632
= Rs 12,646.23170832
_______________________________
Thus Mike have to pay approximately Rs 12,646 after 5 years.
A =?
P= 9456
r = 6% = 0.06
t = 5 yrs
Formula
A= P(1+r)^t
A= 9456×1.06⁵
A = 12646.23
the total amount that he had to pay was 12646 rs

Which equations have no real solution but have two complex solutions?
A 3x>2-5=-8
b 2x>2=6x-5
c 12x=9x>2 +4
d -x>2 - 10x =34
Answer:
see details below
Step-by-step explanation:
First, assume >2 was meant to be &super;. or square.
then the given equations are:
A 3x^2-5=-8
b 2x^2=6x-5
c 12x=9x^2 +4
d -x^2 - 10x =34
In all cases, rearrange equation to identify parameters a, b and c, then calculate determinant using D=b^2-4ac.
A 3x^2x-5=-8
3x^2-5x+8=0, a=3, b=-5, c=8
D=b^2-4ac = (-5)^2-4*3*8 = 25 - 96 = -71 < 0 => 2 complex solutions
B 2x^2=6x-5
2x^2-6x+5, a=2, b=-6, c=5
D=b^2-4ac = (-6)^2-4*2*5 = 36 - 40 = -4 < 0 => 2 complex solutions
C 12x=9x^2 +4
9x^2-12x+4, a = 9, b=-12, c=4
D=b^2-4ac = (12)^2-4*9*4 = 144 - 144 = 0 => 2 real coincident solutions
D -x^2 - 10x =34
-x^2-10x-34, a = -1, b=-10, c=-34
D=b^2-4ac = (-10)^2-4*(-1)*(-34) = 100 - 136 = -36 <0 => 2 complex solutions

6(2x - 11) + 15 = 3x + 12
Answer:
x = 7
Step-by-step explanation:
Lets do the brackets first,
6 × 2x = 12
6 × -11 = -66
------
Calculate the x constant:
12x - 3x = 9x
-------
Then the ones with no x:
-66 + 15 = -51
51 + 12 = 63
-------
Lastly, divide
63 ÷ 9 = 7

A line, y = mx + b. passes through the point (2, 4) and is parallel to y = 3x - 5. What is the value of b?
Answer:
-2
Step-by-step explanation:
Well since this line is parallel to y=3x-5 they must have the same slope
We are just solving for the y-intercept
We have a point (2,4) lets plug it into
y=3x+ b
4 = 3(2) +b
4= 6 +b
-2 = b
The value of b is -2
Answer:
B-value = -2
Step-by-step explanation:
In the picture below Orange line represents the line of "y = 3x - 5", since we know that the line passing through the point (2,4) is parallel to the given line, the slope of the line would be 3x as well. To find b-value or y-intercept we have to plot the point on the graph where the line passing through the points (2,4) intersects the y-axis, in this case it's at (0,-2), therefore the b-value = -2.
Hope this helps!

please help! 20 points. if you guess or just comment to take my points i will make sure ur account gets banned. thanks! i want a simple explanation
Answer:
x = 9
Step-by-step explanation:
Of course I'll do very simple explanation!
every time you see a straight line (nondiagonal) it measures 180°.
so if we're trying to solve for x in this case, we'll subtract 180° - 40° = 140°.
Then use the statement to solve for x
[tex]10x+50=140[/tex]
[tex]10x-50[/tex] = - 50 Subtract 50 from both sides
[tex]10x[/tex] [tex]=[/tex] 90 Divide 10 from both sides
x = 9
Please rate your understanding of the vocabulary from today (planes, points, lines, collinear, coplanar, line segments, rays, and opposite rays.) I understand the definitions of all terms above and I could explain these topics to others. 4 I am not sure if I understand every word completely, but I have enough confidence to try and figure it out. 3 Some terms make sense, but I need some help understanding others. 2 This is new to me and I cannot define these terms now. 1
Answer:
See below
Step-by-step explanation:
A plane is a flat, two-dimensional surface that extends infinitely.
A point is a precise location on a plane.
A line is a one-dimensional figure that has only its length that extends infinitely.
Points are collinear if they all fall on the same straight line.
Points or lines are coplanar if they all fall on the same plane.
Line segments are a line with two endpoints on each end of the segment, which have a definite length.
Rays are lines that have one endpoint and the other end of the line extends infinitely with no endpoint.
Opposite rays are two rays that have a common endpoint that point in opposite directions and form a straight line.
