Answer:
The 95% confidence interval of true proportion of workers who belong to a union.
(0.29657 , 0.40343)
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 600
Given sample proportion p = 35% or 0.35
The 95% confidence interval of true proportion of workers who belong to a union.
[tex](p^{-} -Z_{0.05} \sqrt{\frac{pq}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]
[tex](0.35 -1.96\sqrt{\frac{0.35 X0.65}{600} } , 0.35 + 1.96\sqrt{\frac{0.35 X 0.65}{600} } )[/tex]
( 0.35 - 1.96 (0.02726) , 0.35 + 1.96 (0.02726)
(0.35 - 0.05343 , 0.35 + 0.05343)
(0.29657 , 0.40343)
Final answer:-
The 95% confidence interval of true proportion of workers who belong to a union.
(0.29657 , 0.40343)

The 8th grade students at two middle schools are raising money by washing cars.
Eastern School has already raised $625 and charges $4.50 per car. West School
charges $6.00 per car and has already raised $475. Which of the following equations
can be used to find c, the number of cars each school needs to wash so that the total
amount raised is the same for both schools?
A. 625c +4.5 = 475c + 6
B. 4.50 +625 = 6c +475
C. 625c +6=4750 +4.5
D. 4,5c 1475 = 6c 4625
Answer:
B is the only answer
Step-by-step explanation:
all other answers plug the amount of money (c) onto the whole amount that they've made, multplying in this manner would give a bigger number. B is the only excusable equation since plugging the (c) onto the West school would bring the total closer to the final amount.
Try it out! What is the slope of the line that goes through the points (6,9) and (7.1)?
Answer:
-8
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
1-9/7-6
-8/1
-8
Best of Luck!
Answer: The slope is equal to -8
Step-by-step explanation:
Since we know all of the points we can put it into the equation y2-y1 divided by x2-x1
So we input the numbers into the equation
1-9= -8
7-6= 1
-8/1 comes out to -8

Step-by-step explanation:
Polynomial long division is done using the same methods as for numerical long division. Each quotient term is multiplied by the divisor, and that product subtracted from the dividend to get the new dividend. You are done when the degree of the dividend is less than the degree of the divisor.
As with numbers, 0 is put where a placeholder is needed. Here, that is needed for the (missing) x^2 term in the dividend.
As with numbers, the remainder is expressed as a fraction using the divisor as the denominator.
The full quotient is 4x^2 +2x +11/4 +37/(8x-4).
SOMEONE PLEASE HELP!!! THIS IS MY LAST QUESTION!!!
Answer:
The answer to the question provided is 30.
Step-by-step explanation:
[tex] \frac{18}{27} = \frac{20}{x} \\ \\ \frac{540}{18} = \frac{18x}{18} \\ \\30 = x[/tex]
Happy to help!
=====================================================
Explanation:
Due to the parallel lines, we have two similar triangles. So the sides are proportional.
18/27 = 20/x
2/3 = 20/x
2x = 3*20
2x = 60 .... cross multiply
x = 60/2
x = 30
---------------
Another way you can approach it is to say
18/(18+27) = 20/(20+x)
18/45 = 20/(20+x)
2/5 = 20/(20+x)
2(20+x) = 5*20
40+2x = 100
2x = 100-40
2x = 60
x = 60/2
x = 30
how many times can 200 go into 487
Estimate the product of 2 & 4/11 and 16 & 1/5.
A. about 2 × 16 = 32
B. about 2 × 14 = 28
C. about 3 × 16 = 48
D. about 3 × 14 = 42
Answer:
a
Step-by-step explanation:
Determine what is closer to 2 4/11.
you would- 4/11 to get 2
you would +6/11 to get 3.
So 2 is closer
Do the same with 16 1/5
16 is closer
therefore, it is 2*16=32

Greg worked for 4 hours and took two 15 minute breaks if he worked eight hours yesterday how many minutes in brakes did Greg take
Answer: Greg would have taken 4 breaks, you pretty much multiply the breaks by 2 because 4 x 2 is 8 hours and 2 x 2 is 4 breaks. In total he would have taken 4 breaks yesterday for a total of 60 minutes. I hope that this helped you!

Find the height of an equilateral triangle with side length 8.
Answer:
U need to just do
[tex] \sqrt{3 \div 4} a {}^{2} [/tex]
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The segment from a vertex to the side opposite is a perpendicular bisector.
The equilateral Δ is divided into 2 right triangles with legs 8 and 4
let height be h, then using Pythagoras' identity
h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )
h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value
Evaluate the function E(z)=(z+1)^2 for the following values of z.
a. E(a)
b. E(a + h), h not equal to 0
Use a & b to evaluate the following, for h not equal to 0
c. E(a + h) - E(a) / h =
Answer:
a. E(a) = (a+1)²
b. E(a + h) = (a+h+1)²
c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
Step-by-step explanation:
E(z)=(z+1)²
E(a) = (a+1)²
E(a + h) = (a+h+1)²
E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
