Roberto and Maria Santanos spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and
dryer would cost them a total of $774. How many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer?
HELP PLEASE!
Answer:
72 weeks
Step-by-step explanation:
If 1 week =$10.75 then $774 will be equal to $774×1 week=774 then divide by $10.75=72 weeks
It will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.
We have - Roberto and Maria Santana's who spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and dryer would cost them a total of $774.
We have to determine in how many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer.
If you are saving $5 every day, then in how many days you will save %100?You will save $100 in = [tex]\frac{100}{5}[/tex] = 20 days.
According to question, we have -
Cost of a Laundromat = $10.75/week
Total cost of a new washer and dryer = $774.
The number of weeks it will take for the laundromat cost to equal the cost of a new washer and dryer will be -
n(W) = [tex]\frac{774}{10.75}[/tex] = 72 weeks
Hence, it will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.

assume f(x)=-2x+8 and g(x)=3x. what is the value of (g o f)(3)
Answer:
6
Step-by-step explanation:
(g o f)(3) = g(f(3))
We can find f(3) using its formula with x=3:
f(3) = -2·3 +8 = -6 +8 = 2
Now, we can find g(2) using its formula with x=2:
g(2) = 3·2 = 6
So, the composition value is ...
(g o f)(3) = 6

f(x) = 14 – 0.5x f(30)=
Answer: f(30) = -1
You would substitute every X with 30
Answer:
-1
Step-by-step explanation:
First, plug in 30 to your equation (f(x) = 14 - 0.5(30)
0.5 • 30 is 15, so subtract 15 from 14 and you get -1
A football team is known to run 30% of its plays to the left and 70% to the right. A linebacker on an opposing team notices that, when plays go to the right, the right guard shifts his stance most of the time (80%) and that he uses a balanced stance the remainder of the time. When plays go to the left, the guard takes a balanced stance 90% of the time and the shift stance the remaining 10%. On a particular play, the linebacker notes that the guard takes a balanced stance. (a) What is the probability that the play will go to the left
Answer: 0.6585
Step-by-step explanation:
Given the following :
Proportion of play to the left = 30% = 0.3
Proportion of play to the right = 70% = 0.7
Play to the right:
Shift stance = 80% = 0.8
Balanced stance = (1 - 0.8) = 0.2
Play to the right with balanced stance = (0.2 × 0.7) = 0.14
Play to the right with shifted stance = (0.8 × 0.7) = 0.56
Play to the left:
Balanced stance = 90% = 0.9
Shifted stance = (1 - 0.9) = 0.1
Play to the left with balanced stance = (0.9 × 0.3) = 0.27
Play to the left with shifted stance = (0.9 × 0.3) = 0.03
Probability that play will go to the left if the linebacker takes a balanced stance :
Overall proportion of play with balanced stance :
Balanced with play to the right + balanced with play to the left = (0.14 + 0.27) = 0.41
Balanced play to the left = 0.27
= (balanced play to the left / total proportion of balanced stance)
= 0.27 / 0.41
= 0.6585365
= 0.6585

1. f(x) = x2 + x and g(x) = 2x + 1
a. Evaluate f(g(3))
b. Evaluate g(f(3))
Answer:
f(g(3)) = 56
g(f(3)) = 25
Step-by-step explanation:
fog = f(2x+1)
f(2x+1) = (2x+1)^2 + 2x+1
(2x+1)^2 + 2x+1 = 4x^2+6x+2
f(g(x)) = 4x^2+6x+2
f(g(3)) = 4(3)^2+6(3)+2
f(g(3)) = 56
gof = g(x^2+x)
g(x^2+x) = 2(x^2+x)+1
2(x^2+x)+1 = 2x^2 + 2x + 1
g(f(x)) = 2x^2 + 2x + 1
g(f(3)) = 2(3)^2 + 2(3) + 1
g(f(3)) = 25

The chair of the operations management department at Quality University wants to construct a p-chart for determining whether the four faculty teaching the basic P/OM course are in control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results: Instructor Number of Failures Prof. A 13 Prof. B 0 Prof. C 11 Prof. D 16 What is the estimate of the standard deviation of the sampling distribution for an instructor's sample proportion of failures?
Answer:
0.03
Step-by-step explanation:
Given the following :
Instructor __no of failure __prop (failure /100)
A ________ 13__________0.13
B ________0___________0
C________11___________0.11
D________16__________0.16
Prof. B adds no proportion to the data and hence excluded in the estimation.
Mean(m) = 0.13 + 0.11 + 0.16) / 3
= 0.4 / 3
= 0.1333
Standard deviation :
Σ(X - m)² / N - 1
Σ(0.13 - 0.1333)² + (0.11 × 0.1333)² + ( 0.16 - 0.1333)² = 0.0012668689
= 0.0012668689 / 2
= 0.00063343445
√0.00063343445
= 0.0251681
= 0.03 To 2 decimal places

HELP ME PLEASEEE!!!!!!! I am stuck
Answer:
X = 62
Step-by-step explanation:
The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like
(x + 1) + 55 + x = 180
Now you just solve.
Since there are 2 x's you can combine the like terms making them equal 2x
Now the equation should look like 2x + 1 + 55 = 180
Simplify the other like terms: 2x + 56 = 180
Now you want to get x by itself so you subtract 56 from both sides:
2x + 56 = 180
-56 -56
------------------------
2x = 124
Now to finish getting x by itself, divide both sides by 2.
2x = 124
----- ------
2 2
x = 62
FINALLY you plug in x to see if it worked.
(62 + 1) + 55 + 62 = 180

Answer:
(-2, 3 )
(-1, 2[tex]\frac{1}{2}[/tex])
(0, 2)
(1, 1[tex]\frac{1}{2}[/tex])
(2, 1)
Step-by-step explanation:
You just simply substitue the values given into the equation, and the answer worked out will be the value of y.
a = - [tex]\frac{1}{2}[/tex] × -2 + 2 = 1 + 2 = 3
b = - [tex]\frac{1}{2}[/tex] × -1 + 2 = [tex]\frac{1}{2}[/tex] + 2 = 2[tex]\frac{1}{2}[/tex]
c = -[tex]\frac{1}{2}[/tex] × 0 + 2 = 0 + 2 = 2
d = -[tex]\frac{1}{2}[/tex] × 1+ 2 = -[tex]\frac{1}{2}[/tex] + 2 = 1[tex]\frac{1}{2}[/tex]
e = -[tex]\frac{1}{2}[/tex] × 2+ 2 = -1 +2 = 1

if a number is an integer, then it is odd
Answer:
The integers are, -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). For example, -5 is an integer but not a whole number or a natural number. An odd number is an integer when divided by two, either leaves a remainder or the result is a fraction. One is the first odd positive number but it does not leave a remainder 1. Some examples of odd numbers are 1, 3, 5, 7, 9, and 11. ... Since odd numbers are integers, negative numbers can be odd.
