The city council is considering a law that would ban smoking in all public facilities. A sample has been selected from the community and tested for support of the ordinance. Is there a statistically significant relationship between age and support for the anti-smoking law? Use the five step model as a guide and write a sentence or two interpreting your results.
Age
Less than 40 More than 40
SUPPORT For 145 78 223
Against 103 169 272
Total 248 247 495
Answer:
Reject Null Hypothesis given that P-value < ∝
Step-by-step explanation:
Applying the Five ( 5 ) step model and assuming ∝ = 0.05
First step : determine the Null hypothesis
H0 : Age and support for Anti-smoking = independent
Second step : Determine the alternate hypothesis
Ha : Age and support for Anti-smoking ≠ independent
Thirdly : Identify significance level ( ∝ ) = 0.05
4th step : Calculate the Test statistic and P-value
Chi-squared test = 36.1429 using excel function
P-value = 1 - CHISQ.DIST(36.1429, 1, TRUE) < 0.0001
finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that
P-value < ∝

n= -1
n= 2
n= 5 over 3
n= 5 over 2
* will mark BRAINLIEST *
do not answer just for points pls or will be reported.
Answer:
The answer is B
The answer is 2.
Work:
3/5n-4/5=1/5n
-Combine like terms
3/5n-4/5=1/5n
-3/5n -3/5n
-4/5=-2/5n
Divide by -2/5
-4/5=-2/5n
/ -2/5

Answer:
37.9 degrees
Step-by-step explanation:
Using the law of sines, [tex]\frac{\sin(m\angle C)}{21}=\frac{\sin(47^\text{o})}{25}[/tex]. It follows that [tex]\sin (m\angle C) = \frac{21\sin(47^\text{o})}{25} \approx 0.6143371[/tex]. Therefore, [tex]m\angle C = \sin^{-1}(0.6143371)=37.9^\text{o}[/tex].

PLS HELP !! Find the length of the third side. If necessary, round to the nearest tenth.
Answer: 16
Step-by-step explanation:
Use the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]). A and b are the 2 legs, and c is ALWAYS the hypotenuse.
Plug in the values and solve:
[tex]12^2+b^2=20^2\\144+b^2=400\\b^2=256\\b=16[/tex]
what fractions are equivalent to 2/5?
Answer:
4/10, 6/15, 8/20, 10/25, .
Step-by-step explanation:
Answer:
4/10, 6/15, and 8/20
Step-by-step explanation:
Multiply the numerator and denominator by any of the same number to find equivalent fractions:
2 × 2 / 5 × 2 = 4/10
2 × 3 / 5 × 3 = 6/15
2 × 4 / 5 × 4 = 8/20
You can choose any number you would like to multiply with.

5y+9=39
need the steps
and what is y
Answer:
6
Step-by-step explanation:
5y+9=39
-9 on both sides to get the y by itself =30
5y=30
now divide 5 on both sides and you get y = 6
Hey there!
5y + 9 = 39
SUBTRACT 9 to BOTH SIDES
5y + 9 - 9 = 39 - 9
CANCEL out: 9 - 9 because that gives you
KEEP: 39 - 9 because that helps you solve for y
39 - 9 = 30
NEW EQUATION: 5y = 30
DIVIDE 5 to BOTH SIDES
5y/5 = 30/5
CANCEL out: 5/5 because that gives you 1
KEEP: 30/5 because that helps solve for y
y = 30/5
Answer: y = 6

a. Compute the mean price for a round-trip flight into Atlanta and the mean price for a round-trip flight into Salt Lake City. Round your answers to two decimal places. Atlanta $ 356.73 Salt Lake City $ 400.95 Is Atlanta less expensive to fly into than Salt Lake City
Answer:
Atlanta Mean price:
= Sum of all prices / Number of prices
= (340.1 + 321.6 + 291.6 + 339.6 + 359.6 + 384.6 + 309.6 + 415.6 + 293.6 + 249.6 + 539.6 + 455.6 + 359.6 + 333.9) / 14
= 4,994.2 / 14
= $356.73
Salt Lake City mean price:
= (570.1 + 354.6 + 465.6 + 219.6 + 311.6 + 297.6 + 471.6 + 618.4 + 513.2 + 381.6 + 159.6 + 267.6 + 458.6) / 14
= 5,613.3 / 14
= $400.95

Answer:

stay safe healthy and happy.answer:
5. 6.2 yd
6. 10.4 ft
7. 5.1 mi
8. 8 yd
9. 75.40 m
10. 69.12 m
step-by-step explanation:
to find the radius, divide the diameter (which is given) by 25 — 12.4 / 2 = 6.2 yd
6 — 20.8 / 2 = 10.4 ft
7 — 10.2 / 2 = 5.1 mi
8 — 16 / 2 = 8 yd
to find the circumference of the circle, you can use this formula: C = 2πr9 — 2π(12) = 75.3982236862 = 75.40 m
10 — 2π(11) = 69.115038379 = 69.12 m
