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
MATH 2 HELP PLEASE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Vertical stretch of 2
Step-by-step explanation:
Since there is no fraction, it wouldn't be a shrink, and there's a negative symbol therefore it would also be a reflection, and it wouldn't translate down because it's not inside parenthesis or the square root, and it would actually translate up three, therefore it's a vertical stretch of two

You order two servings of pancakes and a fruit cup . The cost of the fruit cup is $1.50 . You leave a 15% tip. Your total bill is 11.50$ . How much is one serving of a pancake ?
Answer:
$4.25

(1.5 + 2p) x 1.15 = 11.5
1.725 + 2.3p=11.5
2.3p=9.775
p=4.25
chek
4.25+4.25+1.5=10
10×1.15=11.5
If a line passes through the point (0,-8), the y-intercept is
Answer:
y-intercept = -8
Step-by-step explanation:
The y-intercept is where the line goes through the y axis. It is also the value when x = 0. From what the problem gives us, we know the y-intercept is -8 because the x value is 0

Answer:
w(15)=112.5
Step-by-step explanation:
All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.
In this case, you make the equation w(15)=7.5(15) which you can rewrite as
w(15)= 7.5×15, which gives . you 112.5 as the product.

Hector has $590 in his account. He earned $15 per hour for x hours. Jeremy has $545 in his account. He earned $20 per hour for x hours. They both worked the same number of hours and now have the same amount of money. What is the number of hours that each person worked? Write and solve an equation.
Answer:
equation = 590 + 15x = 545 + 20x
No. of hours worked = 9
Step-by-step explanation:
Given that both worked for same number of hours
and
Jeremy worked for for x hours
it meant that Hector also worked for x hours(it is also mentioned same in the problem)
now that we know the number of hours worked in form of x
lets find
total money in their account if they worked for x hours
___________________________________________
For Hector
Money in Hector's account = $590
Earning for Hector in 1 hour = $15
Earning for Hector in x hour = x*Earning for Hector in 1 hour = $15x
Total money in with Hector after x hours of work
= Money in Hector's account + Earning for Hector in x hour = $590 + $15x
Similarly
For Jeremy
Money in Jeremys account = $545
Earning for Jeremy in 1 hour = $20
Earning for Jeremy in x hour = x*Earning for Jeremy in 1 hour = $20x
Total money in with Jeremy after x hours of work
= Money in Jeremy's account + Earning for Jeremy in x hour = $545 + $20x
Given that they same amount of money
thus
$590 + $15x = $545 + $20x
$sign gets cancelled from both sides
590 + 15x = 545 + 20x Thus, we got the required equation
=> 590 - 545 = 20x - 15x
=> 45 = 5x
=> x = 45/5 = 9
Thus, both of them worked for 9 hours
What does the - 8 do in the function k(x)?
k(x) = x^2 - 8
Answer:
the negative 8 is the y-intercept of the equation. This means that this is y value of where 0 is on the x-axis. The point for the y-intercept is (0,8)

Which diagram provides a counter example to the statement below?
“Supplementary angles are never congruent.”
Two or more angles are supplementary if and only if they can add up to [tex]180^{o}[/tex]. Thus, the appropriate option would be C.
Supplementary angles are angles that add up to the value of angle on a straight line i.e [tex]180^{o}[/tex].
Congruent property of angles implies that they have equal value.
Thus, the given statement that: “Supplementary angles are never congruent”, implies that they can not be equal in value. Thus the contrary to the statement would be: “Supplementary angles are sometimes congruent.”
Considering the figures given in the question, the counter example to the given statement is the figure in option C. [tex]180^{o}[/tex]. Because angle 1 and 2 are approximately equal.

hey i need help with a math question thank you :)
Answer:
y = 60x + 20
y = 65x
0 = 5x - 20
5x = 20
x = 4 ---> 4 hours
Substitute x as 4:
y = 65 x 4
y = 260 ---> 260 miles
So the answer is A

(1.2÷0.375−0.2)/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
Answer:
x=1/3
read below to find out how I solved!
Step-by-step explanation:
break it down.
First do 1.2÷0.375−0.2 = 1.2.
it is now 1.2/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
now do 6 4/25 ÷15 2/5 +0.8 = 3
it is now 1.2/3 = (0.016÷0.12+0.7)/x
now do 0.016÷0.12+0.7 and that is 5/6
now you have 1.2÷3 = 5/6 ÷ x
solve for x and you should get x = 1/3!!

discount of 15%. What did Shun pay for the discounted
MP3 player?
Answer:
$57.8
Step-by-step explanation:

68 - 10.2 = 57.8
Answer:
$55.8
Step-by-step explanation:
68 times %15 = 10.2 so subtract 68 by 10.2 and that = 55.8

Answer:
G
Step-by-step explanation:
In F, the graph goes up by two and only to the side by 1. 2/1 simplifies to 2.
In H, y being the double of x would be equal to 2/1 again.
And in J, the numbers are also being doubled.
The slope for G would just be 0, which is undefined.
