To study the output of a machine that fills boxes with cereal, a quality control engineer weighed 150 boxes of Brand X cereal. The frequency distribution in the following table summarizes his findings. Find the standard deviation of the weight of the boxes of cereal. (Round your answer to three decimal places.)

15.3 ≤ x < 15.6 14
15.6 ≤ x < 15.9 25
15.9 ≤ x < 16.2 84
16.2 ≤ x < 16.5 18
16.5 ≤ x < 16.8 9
Answer:
[tex]\sigma = 0.07770[/tex]
Step-by-step explanation:
Given
The above table
Required
The standard deviation
First, calculate the class mid-point. This is the average of the class interval.
The mid-point x is:
[tex]x_1 = \frac{1}{2}(15.3 + 15.6) =\frac{1}{2} * 30.9 = 15.45[/tex]
[tex]x_2 = \frac{1}{2}(15.6 + 15.9) =\frac{1}{2} * 31.5 = 15.75[/tex]
[tex]x_3 = \frac{1}{2}(15.9 + 16.2) =\frac{1}{2} * 32.1 = 16.05[/tex]
[tex]x_4 = \frac{1}{2}(16.2 + 16.5) =\frac{1}{2} * 32.7 = 16.35[/tex]
[tex]x_5 = \frac{1}{2}(16.5 + 16.8) =\frac{1}{2} * 33.3 = 16.65[/tex]
So, we have:
[tex]\begin{array}{cccccc}x & {15.45} & {15.75} & {16.05} & {16.35} & {16.65} \ \\ f & {14} & {25} & {84} & {18} & {9} \ \end{array}[/tex]
Calculate mean
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
[tex]\bar x = \frac{15.45 * 14 + 15.75 * 25 + 16.05 * 84 + 16.35 * 18 + 16.65 * 9}{14 + 25 + 84 + 18 + 9}[/tex]
[tex]\bar x = \frac{2402.4}{150}[/tex]
[tex]\bar x = 16.016[/tex]
The standard deviation is:
[tex]\sigma = \sqrt{\frac{\sum(x_i - \bar x)^2}{\sum f}}[/tex]
[tex]\sigma = \sqrt{\frac{(15.45 - 16.016)^2+ (15.75 - 16.016)^2+ (16.05 - 16.016)^2+ (16.35 - 16.016)^2+ (16.65 - 16.016)^2}{14 + 25 + 84 + 18 + 9}}[/tex]
[tex]\sigma = \sqrt{\frac{0.90578}{150}}[/tex]
[tex]\sigma = \sqrt{0.00603853333}[/tex]
[tex]\sigma = 0.07770[/tex]

What is true about alternate exterior angles?
They sum to 180 degrees.
The are congruent.
They sum to 90 degrees.
They are non-adjacent.
They are adjacent.
9514 1404 393
Answer:
The are congruent.They are non-adjacent.Step-by-step explanation:
Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are alternate exterior angles.
Alternate exterior angles are congruent.
The share a side (the transversal, but not a vertex. So they are non-adjacent.
_____
Additional comment
In this geometry, corresponding angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.

correct 89.6162 to two decimal places
Answer:
89.62
Step-by-step explanation:
Look at the 3rd place of decimals - this is 6 so we add one to the second place.
i tryed my best
The decimal number rounded to 2 decimal places is 89.62
Given data:
The decimal number is represented as 89.6162
To round 89.6162 to two decimal places, we look at the third decimal place.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Since the digit in the third decimal place is 6, which is greater than or equal to 5, we round up the second decimal place.
Hence, rounding 89.6162 to two decimal places, the number is 89.62

If BH = 3, BF = 10, GH = 2, find HD
Answer:
HD = 10.5
Step-by-step explanation:
Given BH = 3, GH = 2, BF = 10
Step 1: To find HF:
HF = BF – BH
HF = 10 – 3
HF = 7
Step 2: To find HD:
We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
⇒ GH × HD = BH × HF
⇒ 2 × HD = 3 × 7
⇒ HD = 10.5
Hence, the value of HD = 10.5.

Solve the equation x = 5/3 (pie) (r^3) for r.
Answer and Step-by-step explanation:
To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.
[tex]x = \frac{5}{3} \pi r^{3}[/tex]
Multiply each side by [tex]\frac{3}{5}[/tex], then divide by [tex]\pi[/tex] (pi)
[tex]\frac{3x}{5\pi } = r^{3}[/tex]
Now, take the cubed root of both sides.
[tex]\sqrt[3]{\frac{3x}{5\pi } } = r[/tex]
^^ That is the answer.

25) The area of a trapezium is 330cm2 and the length of one of
the parallel sides is 14 cm. If its height is 15 cm find the length of
the other parallel side.
Answer
30
steps
area of trapizium is a+b/2 * h.
we have a=14, h=15, area=330 and we need to find b
so, 14+b/2 * 15=330
we divide 15 on both sides so 14+b/2=22
we multiply 2 on both sides so 14+b=44
b=44-14
b=30

The sum of two numbers is 27. One number is 2 times as large as the other. What are the numbers?
Larger number:
Smaller number:
Answer:
Let x be the larger number, and y be the smaller number.
The sum of two numbers is 27. So the equation would be:
x+y=27
The larger number is 3 more than the smaller number. So:
larger number = smaller number + 3
or
x=y+3
Now, we want to get rid of x and solve for y first. Since x=y+3, we can substitute y+3 for x in the equation x+y=27.
Therefore:
(y + 3) + y = 27
Combine like terms:
2y + 3 = 27
Subtract 3 on both sides:
2y = 24
Divide both sides by 2:
y = 12
So the smaller number is 12. The larger number is 3 more than the smaller number, so:
x = 12 + 3
x = 15
The 2 numbers are 12 and 15. Check:
12 + 15 = 27
Answer:
Larger number: 18
Smaller number: 9
Step-by-step explanation:
a + b = 27
----------------------------
a = b × 2
----------------------------
a + b = 27
(b × 2) + b = 27
2b + b = 27
3b = 27
3b ÷ 3 = 27 ÷ 3
b = 9
----------------------------
a = b × 2
a = (9) × 2
a = 18
----------------------------
a + b =27
(18) + (9) = 27
27 = 27
