How many yards of fence does Raul need to
fence in a garden that is 12ą yards long and 9
yards wide?
Don’t tell me to “download the answer” that’s bs
Answers
Answer:
Raul needs 42 yards of fence.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w)
In this question:
The fence is rectangular.
12 yards long means that l = 12.
9 yards wide means that w = 9.
Perimeter:
P = 2(12 + 9) = 2(21) = 42
Raul needs 42 yards of fence.

A random sample of 25 items is drawn from a population. The sample mean is 850 and population standard deviation is 15. Find a 90% confidence interval
Answers
Answer:
The 90% confidence interval of the mean
(846.154, 853.846)
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 25
Given that the sample mean (x⁻) = 850
The standard deviation of the Population (σ) = 15
Level of significance = 0.10
Step(ii):-
The 90% confidence interval is determined by
[tex](x^{-} - Z_{0.05} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.05} \frac{S.D}{\sqrt{n} } )[/tex]
[tex](850 - 1.282\frac{15}{\sqrt{25} } , 850+ 1.282 \frac{15}{\sqrt{25} })[/tex]
(850 - 3.846 , 850 + 3.846)
(846.154 , 853.846)
Final answer:-
The 90% confidence interval of the mean
(846.154, 853.846)

Answers
Answer: [tex](7,\frac{\pi}{2})[/tex]
Step-by-step explanation:
Given
The equation of the circle is [tex]x^2+y^2=r^2[/tex]
Point [tex](0,7)[/tex] lies on the circle
Put the value
[tex]\Rightarrow 0^2+7^2=r^2\\\Rightarrow r=7\ \text{units}[/tex]
for this point, the angle is given by
[tex]\Rightarrow \tan \theta=\dfrac{y}{x}\\\\\Rightarrow \tan \theta=\dfrac{7}{0}\rightarrow \infty[/tex]
That is [tex]\theta \rightarrow 90^{\circ}[/tex]
The polar coordinate is given by [tex](r,\theta)[/tex]
[tex]\therefore\ (7,90^{\circ})\ \text{or}\ (7,\frac{\pi}{2})[/tex]

An airplane is flying with a constant altitude at a speed of 450 mph in a direction 10° north of west directly towards its final destination. The airplane then encounters wind blowing at a steady 34 mph in a direction 85° north of east. If the pilot does not correct his course after encountering the wind, at what speed and in what direction (counterclockwise from east) will the plane be traveling? Speed: _____mph Direction:______ °
Answers
Answer:
your answer is gonna be 579 miles that would be your answer
The ground speed will be 454.2 mph in north east.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
Given that airplane is flying with a constant altitude at a speed of 450 mph in a direction 10° north of west directly towards its final destination.
The airplane then encounters wind blowing at a steady 34 mph in a direction 85° north of east.
The component of an airplane will be
x =450 sin 10
x = -244.8
y = 450 cos 10
x = -377.5
The component of wind will be
x =34sin 85
x = -5.98
y = 34 cos 85
x = -33.4
Then the ground speed will be 454.2 mph in north east.

18 of the 47 people surveyed said they were not interested in trying a sample of a new soft drink. Find probability that a randomly selected person was interested in trying a new drink.
Answers
Answer: 0.62
Step-by-step explanation:
Total people= 47
Let A be the event of selecting person was interested in trying the new drink.
Person not interested in trying a sample of a new soft drink (nA')=18
Person interested in trying a sample of a new soft drink (nA)=47-18=29
Thus probability that a randomly selected person was interested in trying the new drink
P (A) = 29/41 = 0.6170 (or) 0.62
Thus, probability that a randomly selected person was interested in trying the new drink is 0.62.
47-18=29 people interested in the new drink
29/47=0.617
0.617*100=61.7% chance

A plane traveled 588 miles each way to Athens and back. The trip there was with the wind. It
took 7 hours. The trip back was into the wind. The trip back took 14 hours. Find the speed of
the plane in still air and the speed of the wind.
Answers
Answer:
The wind speed is 21 miles per hour, and the speed of the plane in still air is 63 miles per hour.
Step-by-step explanation:
Since a plane traveled 588 miles each way to Athens and back, and the trip there was with the wind and took 7 hours, while the trip back was into the wind and took 14 hours, to find the speed of the plane in still air and the speed of the wind, the following calculations must be performed:
Downwind travel = 588/7 = 84 miles per hour
Headwind travel = 588/14 = 42 miles per hour
84 - 42 = 42/2 = 21
84 - 21 = 63
Therefore, the wind speed is 21 miles per hour, and the speed of the plane in still air is 63 miles per hour.
