The minimum number of unbroken briquets the bag would have to contain for the company to avoid having to replace the bag for free is b) 411.
A standard deviation (or σ) is a degree of the way dispersed the records is with regards to the mean. Low standard deviation approach records are clustered across the mean, and excessive widespread deviation suggests records are greater unfold out. The interval of filled bags is at confidence interval of 95%. At 95% confidence interval, Z=1.96 (from Z tables).But, Z= (x-mean)/SD => 1.96 = (x-450)/20 => x (upper limit)= 20*1.96+450489 bags. Lower limit or minimum number bags to avoid replace= 450-1.96*20 =411 bags.
Therefore, the correct option is b.

An experiment in a wind tunnel generates cyclic waves. When the experiment starts (at time the wind is moving 13 feet per second (the slowest speed recorded). The speed maxes out at 71 feet per second and returns to 13 feet per second after 44 seconds. Let V represent the wind speed (velocity) in feet per second and let t represent the time in seconds. Write a sine equation that describes the wave.
Answer:
The sine equation for the wave is;
y = 29·sin[(π/22)·(x - 11)] + 42
Step-by-step explanation:
The given wind parameters in the wind tunnel are;
The slowest speed of the wind in the wind tunnel, v₁ = 13 feet per second
The maximum speed of the wind, v₂ = 71 feet per second
The time it takes the wind to complete one cycle = 44 seconds
Therefore, we have;
The general form of the sine equation is given as follows;
[tex]y = A \cdot sin \left [B(x - C)\right ] + D[/tex]
The period, T = 44 seconds = 2·π/B
∴ B = 2·π/44 = π/22
Given that the wave starts at the slowest speed, the horizontal shift
The amplitude, A = (v₂ - v₁)/2
∴ A = (71 ft./s - 13 ft./s)/2 = 29 ft./s
The vertical shift, D = v₁ + a = 13 ft./s + 29 ft./s = 42 ft./s
D = 42 ft./s
When x = 0, sin(B·C) = -1
∴ -B × C = -π/2
∴ C = π/2 ÷ B = π/2 ÷ (π/22) = π/2 × 22/π = 11
Therefore, the sine equation for the wave is;
the sine equation for the wave is;
y = 29·sin[(π/22)·(x - 11)] + 42

Josh gets paid at a rate of $10.73 per hour. He also gets paid time and a half for overtime (over 40 hours). If he worked 47 hours this week, what is his pay before taxes?
Answer:
$541.90
Step-by-step explanation:
We'll start with his regular pay, 40 hours times $10.73
10.73 x 40 = 429.20
His overtime pay is 10.73 + 1/2(10.73) = 10.73 + 5.365 = 16.095, rounded to 16.10
He worked 7 hours at the rate of $16.10/hour
16.10 x 7 = 112.70
Add the two totals together for his total pay before taxes:
429.20 + 112.70 = 541.90

Jameson and Quincy each deposit $7,000 into accounts that earn 6% interest, but Jameson earns annual simple interest while Quincy earns annual compound interest. Assuming neither one of them makes any deposits or withdrawals for 5 years, which of the following is a true statement?
Jameson will have about $9,367.58 less in his account than Quincy.
Jameson will have about $267.58 less in his account than Quincy.
Jameson will have about $2,367.58 more in his account than Quincy.
Jameson will have about $2,100 more in his account than Quincy.
Answer:
$267.58
Step-by-step explanation:
Jameson: simple interest
6% =.06 .06 x 5 = .3 .3 x 7000 = 2,100 = interest
6% =.06 .06 x 5 = .3 .3 x 7000 = 2100 2100 + 7000 = 9,100 = total
Quincy: compound interest
6% =.06 .06 x 5 x 1 = .3 x 7000 = 2100
6% =.06 .06 x 5 x 1 = .3 x 7000 = 2100 + 7000 = 9100
.06 x 5 x 1 x 9100 = 2730 + 9100=11830
repeat five times u would get a interest of 2,367.58
and a total of 9,367.58
the total amounts 9,367.58 - 9,100 = 267.58
the interests 2,367.58 - 2,100. = 267.58

Write and evaluate two equivalent numerical expressions that show Distributive Property of Multiplication
Answer:
2(x+5) = 2x+10
Step-by-step explanation:
I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.
2(x+5) = 2x+10
2 times x is 2x. 2 times 5 is 10. So, you get 2x+10
The distributive property of multiplication involves taking the product a certain value and another variable joined by either an addition or subtraction operator.
3(x + 5) = 3x + 15For instance :
a(b + c) = a×b + a×c = ab + ac
The expressions below shows distributive property of multiplication :
3(x + 5) and 3x + 15 exhibits the distributive property of multiplication.
3(x + 5)
Opening the bracket :
3×x + 3×5 = 3x + 15
Hence,
3(x + 5) = 3x + 15

Find the measure of angle YUV
Answer: 77 degrees
Step-by-step explanation:
When looking at an arc, you use the inscribed angle theorem, which states that the measure of an inscribed angle is half of the measure of its interpreted arc. So since the measure of the arc is 154 degrees, you divide that by 2 and that will give you the measure of the angle, which is 77 degrees.
