An algebra tile configuration. 0 tiles are in the factor 1 spot and 0 tiles are in the factor 2 spot. 20 tiles are in the product spot: 1 is labeled x squared, 8 are labeled negative x, and 16 are labeled . the geometric model represents a perfect square trinomial. use the drop-down menus to identify the two factors. factor 1 = factor 2 =
A quadratic equation is written in the form of ax²+bx+c. The factors of the given tile configuration are (x-4).
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
In order to write the algebra tile configuration of the given problem, we need to convert sentences one by one. Therefore, the description can be converted as,
1 is labelled x squared, x²8 are labelled negative x, -8xand 16 are labelled. 16Now, adding all the tiles configuration together we will get,
[tex]x^2 - 8x + 16[/tex]
As we got the quadratic equation now, the roots of the quadratic equation can be written as,
[tex]x^2 - 8x + 16 = 0\\\\x^2-4x-4x+16=0\\\\x(x-4)-4(x-4)=0\\\\(x-4)(x-4)=0\\\\(x-4^2)=0[/tex]
Thus, the factors of the given tile configuration are (x-4).

A club of 50 students is doing volunteer. Each student is volunteering at one of four location. 14 at the hospital, 15 at the pet shelter, 8 at tutoring, 13 at library. What is the probability that the first student volunteers at the library and the other two do not?
Answer:
The probability is 0.1473
Step-by-step explanation:
Given;
total number of students, n = 50
number at hospital, h = 14
number at pet shelter, p = 15
number at tutoring, t = 8
number at library, L = 13
If three students are chosen at random without replacement, the number of students that will be selected to work in other location is given by;
50 - 13 = 37 students
The probability that the first student volunteers at the library and the other two do not is given by;
P(13 students at library) x P(2 out of the 37 students did not)
[tex]= (\frac{13}{50})(\frac{37}{49})(\frac{36}{48} )\\\\ = 0.1473[/tex]
convert 62 feet per second to (5280 = 1 mile)
Answer:
Step-by-step explanation:
if you want to convert to miles per hour, then
in 1 second distance covered=62 ft
In 60 seconds (1 minute) distance covered=62×60=3720 ft.
In 60 minutes (1 hour) distance covered=3720×60 ft=223200 ft
=223200/3=74400 yards
=74400/1760=7440/176=930/22=465/11 miles=42 3/11 miles
62 ft per second=42 3/11 miles per hour.

whats the infinitely, one, no solution
Answer:
Step-by-step explanation:
The infinite solution is when the equation equals something like this:
10 = 10
2 = 2
586 = 586
One solution is when the answer to an equation is something like this
x = 4
x = 17
y = 657
y = 7
No solution is when the equation 'doesn't make sense' or something:
4 = 10
17 = 64
6 = 9

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf underclassmen students have in a one week period. We know from preliminary studies that the standard deviation is around 2. 8. How many students should be sampled to be within 1. 5 drink of population mean with 90% probability?.
Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16

Craig starts at -4 meteres (4 below sea level and sea level is 0) so we add 4 to get to 0.
The school is +10 meters.

= 3/8 (final answer)
Answer:
17/12 or 1 5/12
Step-by-step explanation:
Fraction halfway between refers to the mean of the two fractions.

Anna has $2.53. How much money will Anna have left if she buys a bright yellow highlighter and a thin blue marker?
thin green highlighter $0.35
package of crayons $0.61
thin blue marker $0.80
bright yellow highlighter $0.74
Answer:
$0.99
Step-by-step explanation:
A thin blue marker = $0.80
A bright yellow highlighter = $0.74
First, find the total cost of these two products. Add the costs together:
0.80 + 0.74 = 1.54
Anna has $2.53 in all. Subtract 1.54 from 2.53:
2.53 - 1.54 = $0.99
Anna will have $0.99 left.

A brand new smartphone costs $1200. It decreases in value by 13. 3% every year after its purchase. Which function models the value of the phone x years after its purchase?
Question 8 options:
f(x)=1. 133(1200)x
f(x)=1200(1. 133)x
f(x)=1200(0. 867)x
f(x)=0. 867(1200)x
The function that models the value of the phone x years after its purchase is y = 1200(0.867)^x
Exponential equationsThe standard exponential equation is given as:
y = ab^x
From the given question
a = 1200
b = 1 - 0.133
x is the time
Substitute to have:
y = 1200(1-0.133)^x
y = 1200(0.867)^x
Hence the function that models the value of the phone x years after its purchase is y = 1200(0.867)^x

Don and Linda would like to replace the hardwood flooring in their dining room. The flooring sells for $15.75 a square foot installed. The room size is 15 feet wide by 22 feet long. They can make a 20% down payment but will need to finance the rest at 12% for 42 months
a. What is the down payment?
b. What is the amount financed?
c. What is the monthly payment?
d. What is the total finance charge?
Answer:
a) Down payment = $1039.50
b) Amount financed = $4158
c) Monthly payment = $121.73
d) Total finance charge = $5112.66
Step-by-step explanation:
Area of rectangle = width × length
⇒ area of room = 15 × 22 = 330 ft²
Given:
cost of flooring = $15.75 per ft²⇒ Total cost of flooring = area × cost = 330 × 15.75 = $5197.50
a) Down payment = 20% of $5197.50
= 0.2 × 5197.50
= $1039.50
b) Amount financed = total cost - down payment
= 5197.50 - 1039.50
= $4158
c) Monthly payment = [tex]\dfrac{4158 \cdot \frac{0.12}{12}(1+\frac{0.12}{12})^{42}}{(1+\frac{0.12}{12})^{42}-1}[/tex]= $121.73
d) Total finance charge = monthly payment × number of months
= 121.73 × 42
= $5112.66
