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?
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

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

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
Given that sec(θ)=5/3 and θ is in Quadrant I, what is tan(θ)? Write your answer in exact form. Do not round.
9514 1404 393
Answer:
tan(θ) = 4/3
Step-by-step explanation:
The relationship between secant and tangent is ...
1 +tan² = sec²
The the tangent of the angle is ...
tan(θ) = √(sec²(θ) -1)
tan(θ) = √((5/3)² -1) = √(16/9)
tan(θ) = 4/3

Step-by-step explanation:
The average size of a new house built in a Hays county in 2010 was 1,872 square feet. A random sample of 40 new homes built in Hays County were selected in 2014. The average square footage was 2,031 with a standard deviation of 373 square feet. Does this sample provide enough evidence to conclude that the average house size has increased in the Hays County since 2010? Test at an alpha level of 0.05. Find the test statistic.
Answer:
The test statistic is z = 2.7.
The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.
Step-by-step explanation:
The average size of a new house built in a Hays county in 2010 was 1,872 square feet. Evidence that it has increased?
This means that the null hypothesis is:
[tex]H_0: \mu = 1872[/tex]
And the alternate hypothesis is:
[tex]H_a: \mu > 1872[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
1872 is tested at the null hypothesis:
This means that [tex]\mu = 1872[/tex]
Sample of 40. The average square footage was 2,031 with a standard deviation of 373 square feet.
This means that [tex]n = 40, X = 2031, \sigma = 373[/tex]
Value of the test-statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{2031 - 1872}{\frac{373}{\sqrt{40}}}[/tex]
[tex]z = 2.7[/tex]
Pvalue and decision:
The pvalue of the test is the probability of finding a sample mean above 2031. This is 1 subtracted by the pvalue of z = 2.7.
Looking at the z-table, z = 2.7 has a pvalue of 0.9965
1 - 0.9965 = 0.0035
The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.

(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°
m∠V = 60°

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.
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)
At the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music. Of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical. Determine the empirical probability that the next person entering the store favors
(a) rock music.
(b) country music.
(c) something other then rock, country, or classical music.
Answer:
A) 20%.
B) 26.66%.
C) 40%.
Step-by-step explanation:
Since at the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music, and of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical, to determine the empirical probability that the next person entering the store favors (a) rock music, (b) country music, and (c) something other then rock, country, or classical music, the following calculation must be performed:
A)
60 = 100
12 = X
12 x 100/60 = X
1200/60 = X
20 = X
Therefore, the probability that the next person favors rock music is 20%.
B)
60 = 100
16 = X
16 x 100/60 = X
1600/60 = X
26.66 = X
Therefore, the probability that the next person favors country music is 26.66%.
C)
60 = 100
24 = X
24 x 100 / 60 = X
2400 / 60 = X
40 = X
Therefore, the probability that the next person favors another type of music is 40%.
