A machine fills 24-ounce (according to the label) boxes with cereal. The amount deposited
into the box is normally distributed with a standard deviation of 0.25 ounce. What does the
mean have to be in order for 99.5% of the boxes to contain 24 ounces or more of cereal?
Answers
Answer: We do not know the mean but we do know the standard deviation which is 0.25 ounces. The normal distribution plot below shows the shaded
region at approximately 5% of the area of the total Gaussian distribution.
From a Table we find that 5% is a z = -2.57 and so the mean must be 2.57
multiplied by 0.25 ounces = 3.57 0.25 = 0.643 ounces. The mean value
of box must be 0.643 ounces above the declared 24 ounces. Thus,
Mean value = = 24.643 ounces

In a random sample of 5 residents of the state of Maine, the mean waste recycled per person per day was 2.6 pounds with a standard deviation of 0.69 pounds. Determine the 98% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answers
Answer:
(1.307 ; 3.893)
Step-by-step explanation:
Given that:
Mean, xbar = 2.6
Standard deviation, s = 0.69
Sample size, n = 5
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 5 - 1 = 4
Hence Tcritical = 3.747
Margin of Error = 3.747 * 0.69/sqrt(4)
Margin of Error = 1.293
Lower boundary = (2.6 - 1.293) = 1.307
Upper boundary = (2.6 + 1.293) = 3.893
(1.307 ; 3.893)

Area of sector of a circle = 28.26 meter²
Step-by-step explanation:
Given:
Side of cube = 12 meter
One white section = sector of a circle
Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2
Radius of circle = 6 meter
One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
Area of sector of a circle = 28.26 meter²
The volume of the pyramid is 8in3. What is the height of the pyramid? (Sides are 5in and 4in)
Answers
Answer:
h = 0.4 inches
Step-by-step explanation:
Given that,
The volume of the pyramid is 8 in³.
The sides of the pyramid are 5 in and 4 in.
We need to find the height of the pyramid.
The formula for the volume of pyramid is given by :
V = lbh
Where h is the height of the pyramid
So,
[tex]h=\dfrac{V}{lb}\\\\h=\dfrac{8}{5\times 4}\\\\h=0.4\ in[/tex]
So, the height of the pyramid is 0.4 inches.

3. Sarah makes cookies at a rate of 2 dozen per hour. She has to make
a total of 216 cookies for a wedding party. How long will it take her?
Proportions pls
Answers
Answer:
108 Hours or 4.5 days
Step-by-step explanation:
216/2= 108 hours
108/24= 4.5 days
Answer:
9 hours
Step-by-step explanation:
1 dozen is 12
She makes 24 cookies every hour
Since she has to make a total of 216 cookies, and our objective is to find out how long she will take, then we will divide 216 by 24 and multiply the given number by the amount of hours taken to make 24 cookies.
216/24 = 9
Since 216 divided by 24 is equal to 9, then it will take Sarah 9 hours to make 216 cookies.

B) all sides are equal. Angle V=T=U=180/3=60
(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.
It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.
Subtract 180 from the two 70° to get m∠X:
180 - (70 + 70) = 180 - 140 = 40°
m∠X = 40° is your answer.

The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°

Step-by-step explanation:
The relationship between secant and tangent is ...
1 +tan² = sec²

Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
1) Identify angle relationships
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
2) Solve for angle 6
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
c. 80°
Step-by-step explanation:
We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.
Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.
If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.
Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.
Leaving us with C. 80
