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.

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

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

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.
