Suppose the weights of tight ends in a football league are normally distributed such that σ2=1,369. A sample of 49 tight ends was randomly selected, and the weights are given below. Use Excel to calculate the 95% confidence interval for the mean weight of all tight ends in this league. Round your answers to two decimal places and use ascending order.
Answers
Answer:
Step-by-step explanation:Answer Explanation
Correct answers:
$\left(241.42,\ 262.14\right)$
A 95% confidence interval for μ is (x¯−zα/2σn‾√,x¯+zα/2σn‾√). Here, α=0.05, σ=37, and n=49. Use Excel to calculate the 95% confidence interval.
1. Open Excel, enter the given data in column A, and find the sample mean, x¯, using the AVERAGE function. Thus, the sample mean, rounded to two decimal places, is x¯=251.78.
2. Click on any empty cell, enter =CONFIDENCE.NORM(0.05,37,49), and press ENTER.
3. The margin of error, rounded to two decimal places, is zα/2σn‾√≈10.36. The confidence interval for the population mean has a lower limit of 251.78−10.36=241.42 and an upper limit of 251.78+10.36=262.14.
Thus, the 95% confidence interval for μ is (241.42, 262.14).
The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?
Answers
Answer:
B
Step-by-step explanation:
Formula for finding the volume of a cone: [tex]V=\pi r^{2} \frac{h}{3}[/tex]
From the question, we can tell that the height, h, is equal to 2d or 4r.
h = 4r.
Substitute h into the volume formula:
[tex]V=\pi r^{2} \frac{4r}{3}[/tex]
Rearrange to get the final equation of:
[tex]V=\frac{4}{3} \pi r^{3}[/tex]

Your answer
Answers
Answer:
x= -5/2 (-2.5)
-2(3x+1)=17-4
-2(3x + 1) = 13
3x + 1 = 13/23x = -13/2 - 1
3x=-15/2
x=15/2/3
x=15/2x3
x=-15/6
x=-5/2
Answer:x= -5/2
Step-by-step explanation: −2(3x+1)+4=17
(−2)(3x)+(−2)(1)+4=17(Distribute)
−6x+−2+4=17 (−6x)+(−2+4)=17(Combine Like Terms)
−6x+2=17

Step-by-step explanation:
-3(4 - 3x) = 9x - 12
expand the problem
-12 + 3x = 9x - 12
subtract 12 from both sides
3x = 9x
subtract 9x from both sides
-6x = 0
divide both sides by -6
x = 0

DEFG is an isosceles trapezoid
Answers
Answer:
x=8
Step-by-step explanation:
Since it is an isosceles trapezium, we know that GF and DE are parallel, and that EF = GD. Since we know that co-interior angles always add up to 180 degrees, we know that:
Angle F (13x+4) + Angle E (9x) = 180
So we can write an equation for x and solve it.
13x+4+9x=180
22x + 4 = 180
22x + 4 - 4 = 180 - 4
22x = 176
22x/22 = 176/22
x = 8

find all the numbers such that the number added to itself is less than the number subtracted from 6
Answers
Answer:
All numbers less than 2 or [tex](-\infty, 1][/tex] or [tex](-\infty, 2)[/tex]
Step-by-step explanation:
Given that:
Number is added to itself is less than the number subtracted from 6.
To find:
All such numbers.
Solution:
Let the number be [tex]x[/tex].
Here, an inequality will be made.
When solved, it might give more than one answers.
As per the question statement, let us write the inequality.
Number added to itself [tex]\Rightarrow x +x =2x[/tex]
Number subtracted from six = [tex]6-x[/tex]
As per question:
[tex]2x<6-x\\\Rightarrow 3x<6\\\Rightarrow x<2[/tex]
So, the answer is:
All numbers less than 2 or [tex](-\infty, 1][/tex] or [tex](-\infty, 2)[/tex].

An experiment finds that runners with the longest legs complete a mile run in less time. Identify the relation between leg length and time of a mile run.
Answers
Answer:
The relation between the leg length and the time of a mile run is an inverse relation.
Step-by-step explanation:
Inverse relation is one between two variables in which as the value of one of the variables increases, then the value of the other decreases.
From the given question the longer the leg of a runner, the lesser the time to complete a mile run. This implies that as the length of the leg of a runner increases, the time to cover a mile decreases. Therefore, the relation between the leg length and time is an inverse relation.

Answer:
Concept: Algebraic Representation
You have a daily pay or a y-intercept of 20 Then you have a variable change such that 0.50 is earned for each additional pizza Hence the representation is y=0.50x+20X represents pizzas sold and y represents total payAnswer:
y=0.50x+20

Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)

the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

Answer:
D. 2,787.64 yd
Step-by-step explanation:
The formula for the volume of a cone is ...
V = (1/3)πr²·h
The radius (r) is half the diameter, so is (22 yd)/2 = 11 yd. Putting the given values into the formula, we have ...
V = (1/3)π(11 yd)²(22 yd) = 887.333π yd³ ≈ 2787.64 yd³ . . . . matches D
