Answer: 0.167
Step-by-step explanation:
Given: Total batteries = 10
Batteries that are still working = 6
Number of ways to pick 3 working batteries = [tex]^6C_3=\dfrac{6!}{3!3!}[/tex]
[tex]=\dfrac{6\times5\times4\times3!}{6\times3!}\\\\=20[/tex]
Number of ways of pick 3 batteries out of 10 =
[tex]^{10}C_3=\dfrac{10!}{3!7!}=\dfrac{10\times9\times8\times7!}{6\times7!}\\\\=120[/tex]
Required probability = [tex]\dfrac{20}{120}=0.167[/tex]
Hence, the probability that all of the first 3 she chooses will work = 0.167

how to determine proportional relationship?
In your own words PLEASE
Answer:
to examine the ratio y/x (instead of x/y). If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality.
Step-by-step explanation:
Answer:
In a graph the line must pass through the origin and it has to be a straight line,
In an table the y over x has to be the same for each one

Shelly crane us a realtor she is paid a 3 percent commission on every house she sales. Her sales for the month of march were 95,900.00 129,650.00 and 378,420.00 what is shelly commision in march
Answer: 18119.10
Step-by-step explanation:
Shelly's commision in March will be calculated as:
= (3% × 95,900) + (3% × 129,650) + (3% × 378,420)
= (0.03 × 95900) + (0.03 × 129650) + (0.03 × 378420)
= 2877 + 3889.5 + 11352.6
= 18119.10
Her commission will be 18119.10

Mr. and Mrs. Suralbo earned a net taxable income of P568,986. Find the income tax due.
Answer:
$198,000
Step-by-step explanation:
Since Mr. and Mrs. Suralbo are married and filing jointly, they would fall into the tax slab of 35% as their taxable income ranges between $414,701 to $622,050.
Taxable income = $568,986
Tax rate = 35%
Income tax due = $568,000 * 35/100
= $198,000
Thus, the income tax due for Mr. and Mrs. Suralbo would be $198,000.

a teacher has created a 100 point test with 22 questions. If each multiple choice question is worth 4 points and each short answer is worth 6 points. How many of each type are on the test?
Answer:
There are 16 multiple choices and 6 short answers.
Step-by-step explanation:
Let the number of multiple choice questions be x and the number of short answer questions be y.
x + y = 22 (total number of questions)
4x + 6y = 100 (total number of points)
x = 22 - y
4(22 - y) + 6y = 100
88 - 4y + 6y = 100
2y = 100 - 88
y = 6
x + 6 = 22
x = 16
Hence, there are 16 multiple choices and 6 short answers.

what is the slope of у>- 2х + 3
Answer:
-2x
Step-by-step explanation:
Graph
y > −2x + 3
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Find the values of m and b using the form y = mx + b. m = −2
b = 3
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: −2
intercept: (0, 3)
Graph a dashed line, then shade the area above the boundary line since y is greater than
−2x + 3.
y > −2x + 3

1 has 1 dot
2 has 2 dots
3 has 2 dots
4 has 3 dots
5 has 1 dot
6 has 2 dots
7 has 3 dots
8 has 1 dot
The number of students who reads 3 or fewer books is 10 students. Therefore, option C is the correct answer.
Given that, the line plot shows the number of books read by 15 students over the summer.
We need to find out how many students read 3 or fewer books.
What is the line plot?A Line plot can be defined as a graph that displays data as points or checks marks above a number line, showing the frequency of each value. Here, for instance, the line plot shows the number of ribbons of each length.
Now,
The line plot depicted shows, the number of books read by 15 students.
Books read Number of Students
0 0
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
9 0
Number of students who read more than 3 books
= 3 + 1 +2+3+1+0

$10. How much does a waffle cost? How much does a pancake cost?
9514 1404 393
Answer:
pancake: $0.50waffle: $1.20Step-by-step explanation:
You can model the bills using w and p for the price of a waffle and pancake, respectively.
10w + 4p = 14
5w +8p = 10
Subtract half the first equation from the second:
(5w +8p) -(1/2)(10w +4p) = (10) -(1/2)(14)
6p = 3 . . . . . . . simplify
p = 0.50 . . . . . divide by 6
10w + 4(0.50) = 14 . . . . substitute into the first equation
10w = 12 . . . . . . . . . . . . subtract 2
w = 1.20 . . . . . . . . . . . . .divide by 10
A waffle costs $1.20; a pancake costs $0.50.

Given:
The net value of the bakery (in thousands of dollars) t months after its creation is modeled by
[tex]v(t)=2t^2-12t-14[/tex]
Paul wants to know what his bakery's lowest net value will be.
To find:
The function in a different form (factored or vertex) where the answer appears as a number in the equation.
Solution:
Factor form is used to find the x-intercepts and vertex form is used to find the extreme values (maximum or minimum). So, here we need to find the vertex form.
We have,
[tex]v(t)=2t^2-12t-14[/tex]
[tex]v(t)=2(t^2-6t)-14[/tex]
Adding and subtract square of half of 6 in the parenthesis, we get
[tex]v(t)=2(t^2-6t+3^2-3^2)-14[/tex]
[tex]v(t)=2(t^2-6t+3^2)+2(-9)-14[/tex]
[tex]v(t)=2(t-3)^2-18-14[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]v(t)=2(t-3)^2-32[/tex]
Vertex form:
[tex]f(x)=a(x-h)^2+k[/tex]
where, (h,k) is vertex.
On comparing this equation with vertex form, we get the of the function is (3,-32).
Therefore, the vertex form is [tex]v(t)=2(t-3)^2-32[/tex] and the function has minimum value at (3,-32). It means, minimum net value of the bakery is -32 after 3 months.
Answer:
v(t) = 2(t - 3)^2 - 32. and -32

his week, Michael collected $468 for delivering newspapers. He had 40 repeat customers and 18 new ones. As an incentive, he charged the new subscribers $3 less than the repeat customers. If x represents the amount Michael collects from each repeat customer, which equation models this problem? What is the fee Michael charges each new subscriber?
Answer:
$6
Step-by-step explanation:
Let x be the amount Michael collects from each repeat customer
Since we are given that he charged the new subscribers $3 less than the repeat customers.
So, amount collects from each new customer = x-3
Since he had 40 repeated customers
So, the amount Michael collects from 40 repeat customer = $40x
Since he has 18 new customers
So, amount Michael collects from 18 new customer =$18(x-3)
We are also given that his week, Michael collected $468 for delivering newspapers.
Answer:
$6
40x+ 18 (x-3) = 468
