For a 60% confidence interval, the number of cis that we expect to contain the true mean is of 60% of the total amount.
What is the interpretation of a x% confidence interval?The interpretation of a x% confidence interval it is x% likely that the population parameter(mean/proportion/standard deviation) is between a and b, which are the bounds of the confidence interval.
The bounds a and b of the confidence interval are given by the estimate plus/minus the margin of error.
The interpretation also means that out of n samples, the percentage which are expected to contain the true mean is of x, hence the percentage for this problem is of 60%, as it is the confidence level.
Missing InformationThe problem is incomplete, hence only the first part could be answered.

Maribel pidio 100 refrescos a una tienda,los de naranja se los vendieron a $35.00 y los de cola a $38.00 si pago en total $3620 cuantos refrescos de naranja pideo
Answer:
the number of orange sodas be 60
Step-by-step explanation:
Let us assume the orange ones be x
And, the cola ones be y
Now according to the question
x + y = 100
y = 100 - x.........(1)
35x + 38y = $3,620........(2)
Now put the value of equation 1 in equation 2
So,
35x + 38(100- x) = 3620
35x + 3800 - 38x = 3620
-3x = -180
x = 60
Hence, the number of orange sodas be 60
The number of butterflies in an exhibit is decreasing at an exponential rate of decay. The number of butterflies is decreasing by 5% every year. There are 500 butterflies in the exhibit right now. How many butterflies will be in the exhibit in 7 years? Round your answer to a whole number.
Answer:
349 butterflies
Step-by-step explanation:
The formula for Exponential Decay =
y = a(1 - r)^t
Where y = Size of population after time t = ?
a = Initial size of population = 500
r = Decay rate = 5%
t = Time = 7 years
Hence,
y = 500(1 - 0.05)⁷
y = 500(0.95)⁷
y = 349.16864805 butterflies.
Approximately = 349 butterflies

Movers are filling the truck below with cube shaped boxes. If each box has edge lengths of 12 yard, how many total boxes will fit in the truck? L: 3 1/2 yds W: 5 yds H: 2 1/2 yds
Answer:
14boxes
Step-by-step explanation:
Given the following
Length of truck: 3 1/2 yds
Width of truck: 5 yds
Height of truck: 2 1/2 yds
Volume of truck = Length * Width * Height
Volume of truck = 3 1/2 * 5 * 2 1/2
Volume of truck = 7/2 * 5 * 5/2
Volume of truck = 7/4 cubic yards
For each box
Length L = 1/2 yd
Volume of each box = 1/2 * 1/2 * 1/2
Volume of each box = 1/8 cubic yds
Since 1 box = 1/8 cubic yds
x box = 7/4 cubic yds
Cross multiply
1/8x = 7/4
Cross multiply
4 * x = 7 * 8
4x = 56
x = 56/4
x = 14
Hence the total boxes that can fit in the trunk is 14boxes

Answer:
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
Step-by-step explanation:
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
She need 3 pounds of Chocolate chip cookies and Walnuts
Let us represent
Number of bags of chocolate chip cookies = x
Number of bags of walnuts = y
She need 3 pounds of Chocolate chip cookies and Walnuts
Hence,
We have to convert oz (ounces) to pounds
For chocolate chip cookies
1 oz = 0.0625 pound
12 oz = x
Cross Multiply
x = 12 × 0.0625 pound
x = 0.75pound
For Walnuts
1 oz = 0.0625 pound
4 oz = x
Cross Multiply
x = 4 × 0.0625 pound
x = 0.25pound
Hence,
0.75 pound = $3
0.25 pounds = $2
She can only spend $15
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
Hence,
0.75x + 0.25y = 3..... Equation 1
3x + 2y = 15.... Equation 2
Multiply Equation 1 by 2 and Equation 2 by 0.25
1.5x + 0.5y = 3... Equation 3
1.5x + 4y = 30.... Equation 4
Subtract Equation 3 from 4
3.5y = 27
y = 27/3.5
y = 7.7 bags
Solving for x using Equation 2
3x + 2y = 15.... Equation 2
3x + 2(7.7) = 15
3x + 15.4 = 15
3x = 0.4
x = 0.4/3
x = 0.133 bags
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags

What is the distance between the points (-5, 9) and (4, 9) on the coordinate plane? 9 9 1 1 10 10 90
Answer:
9 units
Step-by-step explanation:
Given: Two points on a coordinate plane are [tex](-5,9),\,(4,9)[/tex]
To find: distance between points [tex](-5,9),\,(4,9)[/tex]
Solution:
According to the distance formula,
Distance between points [tex](a,b)[/tex] and [tex](c,d)[/tex] is equal to [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
Take [tex](a,b)=(-5,9),\,(c,d)=(4,9)[/tex]
Therefore,
Distance between points [tex](-5,9),\,(4,9)[/tex] [tex]=\sqrt{(4+5)^2+(9-9)^2}[/tex]
[tex]=\sqrt{(9)^2}[/tex]
[tex]=9[/tex] units

Write an expression that represents the perimeter of a trapezoid with side lengths z+5,8z-10, 4z+9, and 3z-6
Answer:
Perimeter = (16z - 2)
Step-by-step explanation:
Perimeter of a polygon = sum of the lengths of all sides of the polygon
Sum of all sides of the trapezoid = (z + 5) + (8z - 10) + (4z + 9) + (3z - 6)
By adding like terms,
Perimeter of the trapezoid = ( z + 8z + 4z + 3z) + (5 - 10 + 9 - 6)
= 16z - 2
Therefore, expression representing the perimeter of the trapezoid will be,
(16z - 2)
