on the subway 8 out of 11 people are carrying a briefcase. Based on the information, if there are 700 people on the subway, then about how many do not have a briefcase?
Answer:
About 191 people
Step-by-step explanation:
Given:
On the subway 8 out of 11 people are carrying a briefcase.
There are 700 people on the subway.
Question asked:
About how many people do not have a briefcase ?
Solution:
By applying unitary method:
Out of 11 people, number of people having briefcase = 8
Out of 1 , number of people having briefcase = [tex]\frac{8}{11}[/tex]
Out of 700 people, number of people having briefcase = [tex]\frac{8}{11} \times700\\[/tex]
= [tex]\frac{5600}{11}[/tex]
Number of people not having briefcase = [tex]700 -[/tex][tex]\frac{5600}{11}[/tex]
= [tex]\frac{7700-5600}{11}[/tex]
= [tex]\frac{2100}{11}[/tex] = [tex]190.90[/tex]
Therefore, about 191 people do not have a briefcase on the subway.
Final answer:
To find how many people do not have a briefcase out of 700, calculate the number of people with a briefcase and then subtract that from the total.
Explanation:
On the subway 8 out of 11 people are carrying a briefcase. This can be represented as 8/11 of the people have a briefcase. To find out how many people do not have a briefcase out of 700 people, we can first calculate the proportion that have a briefcase and then subtract that from the total.
To find the number of people with a briefcase:
Proportion with briefcase: 8/11
Number with briefcase out of 700: (8/11) x 700 = 509.09 (round down to 509)
Therefore, the number of people without a briefcase would be: 700 - 509 = 191 people.
Showton Middle School has 840 students. Teresa surveys a random sample of 60 students and finds that 8 of them have more than 3 siblings, How many students at the school are likely to have more than 3 siblings?
Based on a sample of 60 students, where 8 have more than 3 siblings, approximately 112 students out of 840 at Showton Middle School are estimated to have more than 3 siblings.
If there are 840 students at the school, we can use this sample to estimate the total number of students likely to have more than 3 siblings across the entire school population. This is a problem related to proportions within a population.
To make this estimation, we need to set up a proportion based on the sample data:
Sample proportion of students with more than 3 siblings: 8 out of 60, or 8/60.Total number of students in the school: 840.Now we can set up a proportion:
(number of students with >3 siblings) / 840 = 8 / 60
We solve for the unknown number of students with more than 3 siblings by cross-multiplying:
(number of students with >3 siblings) * 60 = 8 * 840
(number of students with >3 siblings) = (8 * 840) / 60
(number of students with >3 siblings) = 112
Therefore, based on Teresa's sample, approximately 112 students at Showton Middle School are likely to have more than 3 siblings.

Well, first off, any ameteur who read the question once would know he is INCORRECT, this is because you can easily see he's dividing it by 3 not 6 like you should be, so 2.99 divided by 6 is 0.498333 ( continuing ) so since this must be rounded to the nearest hundredth, so, 50 cents per bottle.
So question 1: No, because he divided with the incorrect numbers.
Question 2:( I actually don't understand this question, cause we just established he was wrong ) so since I don't understand this one, imma say no, or meh.
CORRECT unit rate: 50 cents per bottle.

Tell if the slope is positive, negative, zero, or no slope.
Answer:
I think the slope is zero
Answer:
The slope is 0.
Step-by-step explanation:
If the slope line is straight with the x-axis, its 0.
If the slope isnt going straight on x nor y-axis, it had a slope of anything greater or less than 0, but not 0.
Use the order pairs to find the linear equation in slope intercept form
(0,10) & (3,2)
[tex]y = \frac{-8}{3}x + 10[/tex] is the equation in slope intercept form
Solution:
Given points are (0, 10) and (3, 2)
We have to find the slope intercept form
Let us first find the slope of line
The slope of line is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here,
[tex](x_1, y_1) = (0, 10)\\\\(x_2, y_2) =(3,2)[/tex]
Substituting the values we get,
[tex]m = \frac{2-10}{3-0}\\\\m = \frac{-8}{3}[/tex]
The equation of line in slope intercept form is given as:
y = mx + c ------- eqn 1
Where, "m" is the slope of line and "c" is the y intercept
Substitute [tex]m = \frac{-8}{3}[/tex] and (x , y) = (0, 10) in eqn 1
[tex]10 = \frac{-8}{3} \times 0 + c\\\\c = 10[/tex]
[tex]Substitute\ m = \frac{-8}{3}\ and\ c = 10\ in\ eqn\ 1[/tex]
[tex]y= \frac{-8}{3}x + 10[/tex]
Thus the equation of line in slope intercept form is found

3rd year---$19,200.00 x .20 =$3,840.00= $19,200.00 - $3,840.00 = $15,360.00
4th year---$15,360.00 x .20=$3,072.00=$15,360.00 - $3,072.00=$12,288.00
5th year $12,288.00 x .20=$2,457.60=$12,288.00 - $2,457.60 =$9,830.40
Round 86 to the nearest 10
Answer:
90
Step-by-step explanation:
"The answer is 90.
To round 86 to the nearest ten, one must look at the digit in the ones place, which is 6 in this case. Since 6 is greater than or equal to 5, the number in the tens place is increased by one. The digit in the tens place is 8, so when it is increased by one, it becomes 9. Therefore, 86 rounded to the nearest ten is 90."

Answer:
[tex](-1,\frac{17}{6})[/tex]
[tex](3,\frac{3}{2})[/tex]
[tex](-5,\frac{25}{6})[/tex]
Step-by-step explanation:
The given equation is [tex]2x+6y=15[/tex]
We substitute the ordered pairs to see which ones satisfies the equation.
For (-1,-8), we put x=-1 and y=-8 to get:
[tex]2(-1)+6(-8)=^?15[/tex]
[tex]-2+-48=^?15\\-50=^?15[/tex]
This is not true.
For [tex](-1,\frac{17}{6}))[/tex] we put x=-1 and [tex]y=\frac{17}{6}[/tex] to get
[tex]2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15[/tex]
This is true
For (3,3/2) we have 2(3)+6(3/2)=15
This implies 6+9=15
15=15
This is also True
For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15
This is also true.

STATE -The Martins bought a condominium for $145,000. Assuming
that the value of the condo will appreciate at most 5% a year, how much
will the condo be worth in 5 years?
The future value of a condominium bought for $145,000 with a 5% annual appreciation over 5 years is calculated using the compound interest formula, resulting in a value of approximately $185,061.
The question is asking us to calculate the future value of an investment in real estate, specifically a condominium that was bought for $145,000 with an annual appreciation rate of 5% over a span of 5 years. To find the value of the condo in 5 years, we use the formula for compound interest, which is:
[tex]A = P(1 + r/n)^{nt}[/tex]
Where:
A is the amount of money accumulated after n years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for in years.
Since the appreciation is compounded annually, n is 1. So, we can simplify the formula to:
[tex]A = P(1 + r)^t[/tex]
Substituting the given values:
[tex]A = $145,000(1 + 0.05)^5[/tex]
Now, let's calculate the future value:
[tex]A = $145,000(1.05)^5[/tex]
A = $145,000(1.2762825)
A ≈ $185,061
The condominium will be worth approximately $185,061 in 5 years.
Solve the equation 3x - 13y = 2 for x.
Hey there!
To solve for x, you must isolate the x term. To do so, first add 13y to both sides so you can leave 3x isolated on one side:
3x - 13y + 13y= 2 + 13y
3x= 2 +13y
Now, divide both sides by 3 to isolate the x variable and get your final answer:
(3x)/3 = (2 + 13y)/3
x = [tex]\frac{2 + 13y}{3}[/tex]
The equation could also be written as x= [tex]\frac{2}{3}+\frac{13y}{3}[/tex] if you choose to separate the 2 and 13y.
I hope this helps!
Answer:
[tex]x = \frac{2 + 13y}{3} \\ [/tex]
Step-by-step explanation:
[tex]3x - 13y = 2 \\ 3x = 2 + 13y \\ \frac{3x}{3} = \frac{2 + 13y}{3} \\ x = \frac{2 + 13y}{3} [/tex]

Ise the terms 4, 12a, 6, 2a, and 24 to make equivalent expressions
Answer:
12a + 24 = 6(2a + 4) is the equivalent expressions
Step-by-step explanation:
Given the terms ; 4, 12a, 6, 2a, and 24
There are two terms with unknown = 12a and 2a
but 12a = 2a x 6 .........(1)
from the last term = 24 = 6 x 4 ...........(2)
add both equation 1 and 2 = 12a + 24
12a + 24 = 6(2a + 4) is the equivalent expressions .
to VERIFY; Use a = 2
substitute into the expression ; LHS = RHS
= 12(2) + 24 = 24 + 24 = 48 (LHS)
FOR RHS = 6(2a+4) = 6(2x2 + 4)
= 6(4+4) = 48
Hence LHS = RHS
