Omar the tent maker wishes to support a 13.4-ft tent wall by attaching 25-ft cable to the top of it, and then anchoring the cable to the ground. If the cable is pulled tight, how far from the base of the tent will it be anchored?
Answer:
21.11 ft
Step-by-step explanation:
This question would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
13.4² + b² = 25²
179.56 + b² = 625
b² = 625 - 179.56
b = 445.44
find the square root of 445.44
b = 21.11 ft

Find the mode of the data set. 46, 44, 49, 54, 51, 50, 47, 41, 47, 51, 51, 40, 53, 50, 52, 53
Answer:
51
Step-by-step explanation:
To find the mode of a data set, you must order the data set from least to greatest and find out which number appears the most. For example, I ordered the data set in this example, and found the out that 51 appeared the most.
zz* + 3iz = p + 9i
where z is a complex number and p is a real constant.
Given that this equation has exactly one root, determine the complex number z
Step-by-step explanation:
I need to use the fact that it has exactly one root to find the y part - do I use the quadratic formula on the last bit I have written?
I have x already and z = x+iy
3i and 3 are two complex numbers that fulfill this equation.
What are complex numbers?A complex number is a number of the form (a + bi), where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex]. The general form of the complex number representation is (a + ib). In this, [a] is called real part and [ib] is called imaginary part.
We have -
zz* + 3iz = p + 9i
Assume the complex number to be -
z = a + ib
Then -
(a + ib)(a - ib) + 3i(a + ib) = p + 9i
a² + b² + 3ai + 3bi = p + 9i
(a² + b²) + i(3a + 3b) = p + 9i
So -
3(a + b) = 9
a + b = 3
(a² + b²) = p
Now -
Assume p = 9
Then -
a + b = 3
a² + b² = 9
we get two possible values -
(a, b) = (0, 3)
and
(a, b) = (3, 0)
It can be seen that the values of complex number depend upon the value of p. For p = 9, two complex numbers fulfill this equation -
0 + i3 = 3i
3 + i0 = 3
Therefore, 3i and 3 are two complex numbers that fulfill this equation.

Answer:
b = 30 yd is the answer.
Step-by-step explanation:
a = 40 yd
b = ?
c = 50 yd
According to the Pythagoras theorem,
a² + b² = c²
40² + b² = 50²
1600 + b² = 2500
b² = 2500 - 1600
b² = 900
b = 30 yd
∴ b = 30 yd is the length of the missing leg.
A random sample of 500 registered voters in Phoenix is asked if they favor the use of oxygenated fuels year-round to reduce air pollution. If more than 313 voters respond positively, we will conclude that at least 60% of the voters favor the use of these fuels.
Required:
a. Find the probability of type I error if exactly 60% of the voters favor the use of these fuels.
b. What is the type II error probability β if 75% of the voters favor this action?
Answer:
[tex]\alpha=0.11767[/tex]
[tex]\beta=0[/tex]
Step-by-step explanation:
From the question we are told that:
Population size size [tex]N=500[/tex]
Sample mean [tex]n=313[/tex]
Null hypothesis [tex]H_0:P=0.6[/tex]
Alternative hypothesis[tex]H_a:P>0.6[/tex]
Generally the equation for for P value is mathematically given by
[tex]P=\frac{n}{N}[/tex]
[tex]P=\frac{313}{500}[/tex]
[tex]P=0.6[/tex]
Generally the mean [tex]\=x[/tex] is mathematically given by
[tex]\=x=np\\\=x=500*0.6[/tex][tex]\=x=300[/tex]
Generally the standard deviation [tex]\sigma[/tex] is mathematically given by
[tex]\sigma=\sqrt{npq}[/tex]
[tex]\sigma=\sqrt{500*0.6*(1-0.6)}[/tex]
[tex]\sigma=10.95[/tex]
a)
Generally the probability of Type_I error [tex]P(X>313)[/tex] is mathematically given as
[tex]P(X>313)=P(\frac{x-\mu}{\sigma}>\frac{313-300}{10.95} )[/tex]
[tex]P(X>313)=P(z>1.187 )[/tex]
Therefore using z table
[tex]\alpha=0.11767[/tex]
b)
Null hypothesis [tex]H_0:P=0.75[/tex]
Alternative hypothesis[tex]H_a:P>0.75[/tex]
Generally the probability of Type_II error [tex]P(X<313)[/tex] is mathematically given as
[tex]P=0.75,n=500\\q=1-0.75\\q=0.25[/tex]
Generally the mean [tex]\=x'[/tex] is mathematically given by
[tex]\=x'=500*0.75[/tex]
[tex]\=x'=500*0.75[/tex]
[tex]\=x'=375[/tex]
Generally the standard deviation [tex]\sigma[/tex] is mathematically given by
[tex]\sigma=\sqrt{npq}[/tex]
[tex]\sigma=\sqrt{500*0.75*(1-0.75)}[/tex]
[tex]\sigma=9.68[/tex]
Therefore
[tex]P(X<313)=P(\frac{x-\mu}{\sigma}<\frac{313-375}{9.68} )[/tex]
[tex]P(X<313)=P(z<-6.405)[/tex]
Therefore from standard normal table
[tex]P(X<313)=0[/tex]
[tex]\beta=0[/tex]

A baseball team plays in a stadium that holds 54000 spectators. With the ticket price at $8 the average attendance per game has been 20000. When the price dropped to $6, the average attendance rose to 27000. Assume that attendance is linearly related to ticket price.

What ticket price would maximize revenue? (round to the nearest cent)
9514 1404 393
Answer:
R(p) = -3500p^2 +48000p . . . revenue function
$6.86 . . . price for maximum revenue
Step-by-step explanation:
The 2-point form of the equation for a line can be used to find the attendance function.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (27000 -20000)/(6 -8)(x -8) +20000
y = -3500(x -8) +20000
y = 48000 -3500x . . . . y seats sold at price x
The per-game revenue is the product of price and quantity sold. In functional form, this is ...
R(p) = p(48000-3500p)
R(p) = -3500p^2 +48000p . . . per game revenue
__
Revenue is maximized when its derivative is zero.
R'(p) = -7000p +48000
p = 48/7 ≈ 6.86
A ticket price of $6.86 would maximize revenue.

Evaluate the six trigonometric functions of the angle 0?
Step-by-step explanation:
In the above right Angled triangle , we have ,
perpendicular = 12base = 9hypontenuse = ?For finding hypontenuse use Pythagoras Theorem , we have ,
⇒ h² = p² + b²
⇒ h² = 9² + 12²
⇒ h² = 81 + 144
⇒ h² = 225
⇒ h = √225
⇒ h = ± 15
⇒ h = 15 [ Neglect -ve value ]
Therefore ,
cosθ = b/h = 9/15sinθ = p/h = 12/15tanθ = p/b = 12/9cosecθ = h/p = 15/12 secθ = h/b = 15/9 cotθ = b/p = 9/12two friends bought a strip of tickets for the school carnival. Arlo used 5/6 of his tickets. jayson used 6/6 of his tickets.
::::::::::::::::::::
Answer:
total number of tickets bought: 12
total number of tickets used: 11
Jayson used 1 more ticket than Arlo
Step-by-step explanation:
Erm, I don't know what you want answered, but here's some basics:
So to find how many total tickets were bought, we just have to add both of the strips together:
6 + 6 = 12
So the total number of tickets bought was 12.
To find the amount of ticket used, you have to add the top numbers together:
5 + 6 = 11
So the total number of tickets used is 11.
If you wanted to find how many more tickets Jayson used than Arlo, you'd have to subtract Arlo's tickets from Jayson's:
6 - 5 = 1
So Jayson used 1 more ticket than Arlo.

You buy tomatoes in 25-pound cases. One batch of Cobb salad requires 1.1 ounces of tomatoes. How many portions can be made with one case? Round down (don’t include partial portions).
Answer:
363 portions can be made with one case.
Step-by-step explanation:
Since I buy tomatoes in 25-pound cases, and one batch of Cobb salad requires 1.1 ounces of tomatoes, to determine how many portions can be made with one case, the following calculations must be performed:
1 pound = 16 ounces
25 pounds = 400 ounces
400 / 1.1 = 363.63
Therefore, 363 portions can be made with one case.

Your marketing team has conducted two focus group sessions to evaluate a new product design. The first focus group consisted of teenagers and resulted in four out of five liking the new product. The second group was made up of parents of young children. Only one out of five people in this group said they liked the same new product as the teens. With 90% confidence (Z = 1.64), can you say that there is a difference between the views of these two populations? Please show your calculations, use 2 decimal places in your calculation answer, and justify your answer regarding differences.
Answer:
Since the calculated Z falls in the critical region therefore the null hypothesis is rejected and concluded that there is a difference between the views of these two populations.
Step-by-step explanation:
1) Formulate the hypotheses:
H0 : p1=p2
Ha: p1 ≠ p2
2) The significance level is chosen at ∝= 0.1
3) The critical region is Z∝/2 ≥ ± 1.645
4) The test statistic under H0 is
Z = p1^- p2^/ √p^q^( 1/n1 + 1/n2)
p1^= proportion of of teenagers liking the new product.
p2^ = proportion of of parents of young children liking the new product.
p1^= 4/5
p2^= 1/5
p^= 5(0.8) + 5(0.2)/5+5= 4+1/10= 0.5
q^= 0.5
Thus
Z= p1^- p2^/ √p^q^( 1/n1 + 1/n2)
z= 0.8-0.2/√0.5*0.5( 1/5 + 1/5)
z= 0.6/ 0.316227
z= 1.897
5) Conclusion:
Since the calculated Z falls in the critical region therefore the null hypothesis is rejected and concluded that there is a difference between the views of these two populations.
