3.128 Who Smokes More: Male Students or Female Students? Data 1.1 includes lots of information on a sample of 362 college students. The complete dataset is available at StudentSurvey. We see that 27 of the 193 males in the sample smoke, while 16 of the 169 females in the sample smoke. We will investigate the difference in proportions of male and female students who smoke.
Answer:
0.0452
Step-by-step explanation:
Given that:
There are a total of 193 males in the sample.
Number of males who smoke = 27
There are a total of 169 females in the sample.
Number of females who smoke = 16
The ratio of people who smoke to the total number of people is given by the formula:
[tex]\dfrac{\text{Number of people who smoke}}{\text{Total number of people in the sample}}[/tex]
So, the ratio of males who smoke is given as:
[tex]\dfrac{27}{193}=0.1399[/tex]
And
The ratio of females who smoke is given as:
[tex]\dfrac{16}{169} = 0.0947[/tex]
The difference between the ratio is = 0.1399 - 0.0947 = 0.0452

Answer:
x=22.5
Step-by-step explanation:
Edwards Manufacturing Company purchases two component parts from three different suppliers. The suppliers have limited capacity, and no one supplier can meet all the company’s needs. In addition, the suppliers charge different prices for the components. Component price data (in price per unit) are as follows:
Supplier
Component 1 2 3
1 $12 $13 $10
2 $15 $12 $10
Each supplier has a limited capacity in terms of the total number of components it can supply. However, as long as Edwards provides sufficient advance orders, each supplier can devote its capacity to component 1, component 2, or any combination of the two components, if the total number of units ordered is within its capacity. Supplier capacities are as follows:
Supplier 1 2 3
Capacity 525 975 900
If the Edwards production plan for the next period includes 1025 uni
Answer:

Component 2 7875 3600 11475
Total cost 7875 5225 9000 22100
Step-by-step explanation:
Table 1:
Supplier
Component 1 2 3
1 $12 $13 $10
2 $15 $12 $10
Table 2:
Supplier 1 2 3

Now we are supposed to find production plan for the next period includes 1025 units of component 1 and 825 units of component 2
So,

suppose you are organizing a party and have a budget of b dollars for the appetizers. You plan to order v vegetarian spring rolls at $0.75 each and s shrimp rolls at $0.95 each.
The equation 0.75v+0.95s=b represents this constraint.
Solve 0.75v+0.95s=b for v
When would it be most helpful to use this equation?
Answer:
v = b/0.75 - 0.95s/0.75
Or
v = (b - 0.95s) / 0.75
Step-by-step explanation:
Solve 0.75v + 0.95s = b for v
This means making v the subject of the formula
0.75v + 0.95s = b
Subtract 0.95s from both sides
0.75v + 0.95s - 0.95s = b - 0.95s
0.75v = b - 0.95s
Divide both sides by 0.75
v = (b - 0.95s) / 0.75
v = b/0.75 - 0.95s/0.75
The equation will be useful in determining the number of vegetarian

Answer:
No integers are irrational.
Step-by-step explanation:
Think about the real number system, whole numbers contain natural numbers, integers contain whole numbers, rational numbers contain integers, and real numbers contain all of these including irrational numbers. An irrational number is separate from the rest of the real numbers because it cannot be expressed or written as a fraction or decimal.

2. conjugate 7-√b
-Please give an explanation!!
Answer:
1. [tex]-5-\sqrt{x}[/tex]
2. [tex]7+\sqrt{b}[/tex]
Step-by-step explanation:
The conjugate of a radical expression
[tex]a+\sqrt{b}[/tex]
is the expression
[tex]a-\sqrt{b}[/tex]
And vice-versa.
The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.
The question asks to find the conjugate of:
1. [tex]-5+\sqrt{x}[/tex]
The conjugate is
[tex]-5-\sqrt{x}[/tex]
2. [tex]7-\sqrt{b}[/tex]
The conjugate is

what is 0.0042 as a fraction in simplest form
Answer:
21/5000
Step-by-step explanation:
0.0042 takes the form of 21/5000 as a fraction.
Answer:
21/500
Step-by-step explanation:
0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)
42 is an even number so, divide by 2 to simplify.
42/2 = 21 and 1000/2 = 500
21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.

how are unit rates and equivalent ratios realted?
Answer:
A unit rate is a special kind of ratio, where the second number, or the denominator, is equal to one. With a unit rate, you are comparing a quantity to one. Some common unit rates are miles per gallon, price per pound, and pay rate per hour. ... Next, divide the price by the pounds so you can find the unit rate.

Statement A swimming pool contains 500 gallons of water. A hose is turned on, and it fills the pool at a rate of 24 gallons per minute. Which expression represents the amount of water in the pool, in gallons, after 8 minutes? A. 500 . 24 . 8 B. 500 + 24 + 8 C. 500 + 24 . 8 D. 500 . 248
Answer:
c. 500 + 24 * 8
Step-by-step explanation:
if there is 500 gallons of water already in the swimming pool and we are trying to add more and we are adding 24 gallons for 8 minutes to the already existing pool of water.
The expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes. The correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
If the swimming pool currently has 500 gallons of water in it and we are trying to add more, we would add 24 gallons of water over the course of 8 minutes.
As per the given information, the required expression would be as
500 + 24 × 8
Thus, the expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes.
Hence, the correct answer would be option (C).

Step-by-step explanation:
You find a fraction that is equal 2/3 and has a multiple of 4 for the numerator. Then you have to multiply the numerator and the denominator by 2 then you get 4/6 divided by 4, since 2/3 is equal to 4/6. So the answer is 1/6.

After 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
To find the total cost of the songs,
= 12 songs × $0.80/song = $9.60
Then, the total cost of the subscription and the songs over 6 months:
= $9.99 + (6 × $9.60)
= $9.99 + $57.60
= $67.59.
So, after 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.
