Their vehicles was recorded for each sample. The sample proportions were used to construct the 95 percent confidence interval for a difference in population proportions (FWD minus AWD ) for satisfied owners. The interval is given as (−0.01,0.12) . A car company believes that the proportion of satisfied owners of AWD AWD vehicles differs from the proportion of satisfied owners of FWD FWD vehicles. Does the confidence interval provide evidence that this belief is plausible?
Answer:
[tex] -0.01 \leq p \leq 0.12[/tex]
The confidence is 0.95 or 95% and the significance would be given by: [tex] \alpha=1-0.95=0.05[/tex]/
For this case our confidence interval contains the value 0. So then we can conclude that we don't have significant differences in the the proportion of satisfied owners of AWD vehicles from the proportion of satisfied owners of FWD at the significance level used of 5%. So then the claim that the two proportions are different is incorrect with the results obtained
Step-by-step explanation:
The confidence interval for the true proportion would be given by this formula
[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
And for this case we have the following result:
[tex] -0.01 \leq p \leq 0.12[/tex]
The confidence is 0.95 or 95% and the significance would be given by: [tex] \alpha=1-0.95=0.05[/tex]/
For this case our confidence interval contains the value 0. So then we can conclude that we don't have significant differences in the the proportion of satisfied owners of AWD vehicles from the proportion of satisfied owners of FWD at the significance level used of 5%. So then the claim that the two proportions are different is incorrect with the results obtained

Pythagorean Theorem.
Answer:
d = 5.4
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
a = 2
b = 5
2^2 + 5^2 = c^2
4 + 25 = c^2
29 = c^2
c = 5.4
Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
Using pythagorean theorem you will get 5 squared plus 2 squared equals c squared. Which is 25+4= 29 = c squared. That's the answer it wont simplify any further.
The area of one of the smaller circles is 8/ in². Find the area of the shaded region.
A. pi in.²
B. 4 pi in.²
C. 8 pi in.²
D. 16 pi in.²
The answer is D btw i just submitted my quiz
Answer:
Area of shaded region = 16π in² (D)
Step-by-step explanation:
The question is incomplete without the diagram if the circles. Find attached the diagram used in solving the question.
Area of the smaller circle = 8π in²
Area of a circle = πr²
πr² = 8π
r² =8
r = √8 = 2√2
From the diagram, there are two smaller circles in a bigger circle.
The radius of the bigger circle (R) is 2times the radius of the smaller circle (r)
R = 2r
Area of bigger circle = πR²
= π×(2r)² = π×(2×2√2)²
= π×(4√2)² = π×16×(√2)²
Area of bigger circle = π×16×2
Area of bigger circle = 32π in²
Since there are two smaller circles in a bigger circle
Area of shaded region = Area of bigger circle -2(area of smaller circles)
Area of shaded region = 32π in² - 2(8π in²)
Area of shaded region = 32π in² - 16π in²
Area of shaded region = 16π in²

Answer:
a) Número de personas que suben a un autobús en una parada.c) Conocer el ganador de la Liga de Campeones.Step-by-step explanation:
This problem is about random experiments.
Random experiments are defined as experiments where the outcome can't be predicted. To ensure that result, the subjects are selected randomly. So, in this case, the right answer must be a situation where subjects are randomly present.
People taking the bus is a random experiment, because there's no the exact subjects in a bus at any time, it happens randomly.
Also, the winner of a sport league is also a random experiment, because it happens after several games which cannot be predicted.
Therefore, the right answers are a and c.

How do I solve this problem? Please help me. Thank you very much.
Step-by-step explanation:
15 - 5n = 2n + 1
Bringing like terms on one side
15 - 1 = 2n + 5n
14 = 7n
14/ 7 = n
2 = n
Answer:
Step-by-step explanation:
First distribute. 5•3 and 5•n.
This gives you 15-5n=2n+1
Next add 5n to both sides.
This will give you 15=7n+1
Then you will subtract 1 from both sides.
14=7n
Finally you divide by 7 so you can get n by itself.
Your answer will be 2=n

You are buying fabric to make a patio umbrella in the shape of a regular hexagon, as shown. The blue fabric costs $3.50 per square yard and the white fabric costs $2 per
square yard. You can only order whole numbers of square yards of fabric. What will be the cost of the fabric for this project?
5 ft
3
Answer:
cost of the fabric = $22
Step-by-step explanation:
The picture is a regular hexagonal which means it has six sides of equal length. The triangle in the hexagons are equilateral triangle. This means they have equal length. The blue portion is just like half the area of the hexagon while the white part is also half the area . Note both colors cover 3 triangle each.
area of the hexagon = 3/2 × √3 × a²
where
a = sides
area of the hexagon = 3/2 × √3 × a²
a = 5 ft
convert ft to yard
3 ft = 1 yard
5 ft = 5/3 = 1.6666666667 yards
area = 3/2 × √3 × 1.6666666667²
area of the hexagon = 7.21687836516 yard²
Half of the area is the blue section area because 3 triangle makes half of the hexagon = 7.21687836516/2 = 3.60843918258 yard². Note we can only order whole number of square fabric . Therefore, 3.60843918258 ≈ 4
blue fabric cost $3.50 per square yard.
The cost for this yard = 4 × 3.50 = $14
white fabric cost $2 per square yard .
The cost for this yard = 4 × 2 = $8
Total cost = 14 + 8 = $22
cost of the fabric = $22

Find the circumference of each circle.
Answer:The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c).
circle diameter radius
A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d)
Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
The circumference of a circle is found using this formula: so the answer is B

You throw a ball up in the air.the basketball's height,in feet,is given by the function:h=-16t^2+30t+4,where t is the time in seconds after the ball leaves your hand.Find the greatest height the ball reaches(use a calculator).
Answer:
18.0625 ft
Step-by-step explanation:
Greatest height is when:
t = -b/2a
t = -30/2(-16)
t = 15/16
Greatest height is:
-16t(15/16)² + 30(15/16) + 4 = 289/16
= 18.0625m

Solve the right triangle, AABC, for the missing side and angles to the nearest
tenth given sides a = 14.9 and b = 17.5.
Answer:
The missing side is 22.98, or rounded to the nearest tenth, 23
The angles are 90, 40.37, and 49.63
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem;
[tex]a^2 + b^2 = c^2[/tex]
Since a = 14.9 and b= 17.5, we need to find the missing side, or c
[tex]14.9^2 + 17.5 ^2 = c^2[/tex]
Using a calculator this gives us;
528.26 = [tex]c^2[/tex]
Now to undo [tex]c^2[/tex], we have to square root both sides
[tex]\sqrt{528.26} = \sqrt{c^2}[/tex]
22.98 = c
Now to round to the nearest tenth, we know that .9 is greater than 5, so we can round 22.98 to 23
Now to find the angles.
We know that the triangle has a hypotenuse of 23, a short side of 14.9 and a long side of 17.5.
I labeled the side opposite of 14.9, x, and I will use sin to solve for the angle.
We know that sin= opposite/hypotenuse
So, sin(x)=14.9/23
Since we want to find the angle we must use the inverse of the trig function.
[tex]sin^-^1[/tex](14.9/23) = x
By using a calculator we get
x=40.37
Now since we know that this is a right triangle, we have a 90 degree angle.
So, we can subtract from 180 to find the third angle.
180-90-40.37=49.63
The angles of the triangle are 90, 40.37 and 49.63.
Hope this helped let me know if this can be explained further or if anything is wrong! : )
