Answer:
1. 9 bounds of carbon dioxide
2. 27 bounds of carbon dioxide
Step-by-step explanation:
So let's find a unit rate: 1 to 9
"Why is it 1:9?"
If I can find divide 72 pounds into 8 hours? What would I find? You would find the pounds for each other
Example: 72/8=9. So If 9 carbon dioxide per hour. I can do 3 hours is 27 pounds of carbon dioxide.
So to sum it up, 72/8=9 so 1:9 can be used to figure out any amount of pounds used in a certain number of hours. So If 3 hours, then 27 pounds.
Answer:
1. 9 pounds of carbon dioxide
2. 27 pounds of carbon dioxide
Step-by-step explanation:
Well, I just know it.

There has been much media coverage of the high cost of medicinal drugs in the United States. One concern is the large variation from pharmacy to pharmacy. To investigate, a consumer advocacy group took a random sample of 100 pharmacies around the country and recorded the price (in dollars per 100 pills) of Prozac. Compute the range, variance, and standard deviation of the prices. Discuss what these statistics tell you.
Data for the question :
102.05 99.85 112.3 97.15 111.23 105.37 105.64 106.5 102.97 107.82 106.36 111.24 107.28 114.14 106.28 106.96 98.25 111.55 107.75 101.02 101.12 97.7 97.66 100.54 115.77 112.91 111.04 112.15 102.87 101.14 107.13 108.56 109.56 103.57 108.68 104.59 116.74 116.22 100.22 103.97 111.2 109.34 115.78 101.59 107.93 104.23 96.25 103.84 102.47 102.96 99.26 101.42 108.58 107.69 99.88 102.71 111.25 99.4 117.04 106.35 110.44 102.34 107.25 107.63 105.2 109.14 115.54 101.51 108.49 112.32 109.27 97.54 102.46 105.94 109.42 111.05 102.63 106.99 102.03 108.84 118.8 108.64 95.35 105.47 104.45 102.15 111.4 108.27 104.82 108.4 109.05 116.11 103.7 121.2 99.62 102.81 109.56 103.35 113.02 103.79
Answer:
Range = 25.35
Variance = 29.46
Standard deviation = 5.43
The variation in price of Prozac is high
Step-by-step explanation:
The range of the data :
Maximum - Minimum.
121.2 - 95.35 = 25.35
The variance, s :
s² = Σ(X - m²) / n - 1
Mean, m = Σx / n
X = individual data point
m = mean of data
n = sample size
Using a calculator of save time and ensure accuracy :
s² = 29.45522
The standard deviation, s
s = sqrt(variance)
s = sqrt(s²)
s = sqrt(29.45522)
s = 5.42726.
The range, variance and standard deviation, all measure the degree of variation in a dataset. The values of these statistical measure obtain for the price of 1 product across different pharmaceutical stores, suggests thatvthe variation in price is high;
With a range of about 25.35 and standard deviation of 5.43
Aldos coffee shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Aldo $4.15 per pound, and type of B coffee costs $5.25 per pound. This month, Aldo made 119 pounds of the blend, for a total cost of $548.85. How many pounds of type B coffee did he use?
Let A represent amount of Type A coffee pounds used.
Let B represent amount of Type B coffee pounds used
A + B = 156
B = 156 - A
A = 156 - B
5.80A + 4.65B = 826.60
580 (156 - B) + 4.65B - 826.60 = 0
904.8 - 5.80B + 4.65B - 826.60 = 0
904.8 - 1.15B - 826.60 = 0
78.2 - 1.15B = 0
78.2/1.15 = 1.15B/1.15
68 = B
B = 68 pounds of Type B coffee

Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures
[tex]\frac{PR}{PQ} =\frac{SU}{ST}[/tex] [tex]\frac{21}{14}= \frac{6}{4}[/tex]
∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula
[tex]A+B+C=180[/tex]
[tex]46+70+C+180[/tex]
[tex]116+C=180[/tex]
subtract 116 from both sides
[tex]C=64[/tex]
Therefore ∠Q is equal to 64 degrees

Step-by-step explanation:
3. x^2 + 9x + 18
To check if it is factorable, first check the discriminant
b^2 - 4ac
9^2 - 4(1)(18)
81 - 72
9
Since D > 0, there are real number solutions
Now let us try and factor
Find a number that adds to 9 and multiplies to 18
3 and 6 work
Rewrite the equation as
x^2 + 3x + 6x + 18
x(x + 3) + 6(x + 3)
(x + 6)(x + 3)
4. x^2 - 4x - 12
To check if it is factorable, first check the discriminant
b^2 - 4ac
(-4)^2 - 4(1)(-12)
16 + 48 = 64
Since D > 0, there are real number solutions
Now let us try and factor
Find a number that adds to -4 and multiplies to -12
-6 and 2 work
Rewrite the equation as
x^2 - 6x + 2x - 12
x(x - 6) + 2(x - 6)
(x + 2)(x - 6)

The Blinking Rockets baseball team has had 127,034 visitors to their fan website. Rounded to the nearest ten thousand how many visitors have they had
Answer:
[tex]Visitors = 130000[/tex]
Step-by-step explanation:
Given
[tex]Visitors = 127034[/tex]
Required
Approximate to the nearest ten thousand
First, identify the digit at the ten thousand position
From the given numbers of visitors, the digit is 2.
So, the next digit (which is 7) will be approximated and added to 2.
7 > 5. So, 1 will be added to 2.
The number of visitors becomes:
[tex]Visitors = 130000[/tex]

The table shows the number of words per minute Josylyn can type. What is the missing value?
Answer:
52
Step-by-step explanation:
First, we want to see how we get from 104 to 156.
Looks like we add 52 to get the next.
104 + 52 = 156
156 + 52 = 208
Logically if we want to go back, we simply subtract 52.
104 - 52 = 52

Substitute t = 3 and t = 6 to determine if the two expressions are equivalent. 3 (2 t + 5) 6 t + 15 Which statements are true? Select the three correct answers. The value of both expressions when t = 3 is 33. The value of both expressions when t = 3 is 23. The value of both expressions when t = 6 is 41. The value of both expressions when t = 6 is 51. The two expressions are equivalent. The two expressions are not equivalent.
Answer:
If t= 6
3 (2 x 6 + 5) 6 x 6 + 15
3 (12+5) 36 + 15
3 x 17 =51
= 51
