How would the expression x-9 be rewritten using Difference of Squares?
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out
Mo and Kim are sharing 72 pencils in the ratio 3:5
How many pencils does Mo get?
Need help
Step-by-step explanation:
let the ratio of pencils be 3x and 5x.
3x+5x=72
8x=72
X=72/8
X= 9
3x=3×9=27
5x=5×9=45 Answer
27 pencils mo get
Answer: Mo gets 27 pencils
Step-by-step explanation:
Given
- There are 72 pencils in total
- Let 3x be the number of pencils Mo gets
- Let 5x be the number of pencils Kim gets
Solve
Given
3x + 5x = 72
Combine like terms
8x = 72
Divide 8 on both sides
8x / 8 = 72 / 8
x = 9
Mo = 3x = 3 ( 9 ) = 27 pencils

Find the 9th term of the geometric sequence 5, -25, 125, ...
9514 1404 393
Answer:
1,953,125
Step-by-step explanation:
The first term is a1 = 5; the common ratio is r = -25/5 = -5. The generic term is ...
an = a1×r^(n-1)
an = 5×(-5)^(n-1)
So, the 9th term is ...
a9 = 5×(-5)^(9-1) = 1,953,125
Ben in n years old chloe is twice as old as Ben Dan is 5 years younger than Ben
The total of bens age, chloes age, and Dan’s age is T years
Find a formula for T in terms of n
Answer:
T = 4n - 5
Step-by-step explanation:
Ben = n
Chloe = 2n
Dan = n - 5
n + 2n + (n - 5) = T years
3n + n - 5 = T years
4n - 5 = T years
2y + 3y -3y -6(y + 2) = -y + 6
Answer:
Step-by-step explanation:
2y + 3y -6(y + 2) = -y + 6
Solving lik terms
5y - 6(y + 2) = - y + 6
5y - 6y - 12 = - y + 6
-y - 12 = - y + 6
Bringing like terms on one side
-12 - 6 = - y + y
-18 = y

Dorothy Little purchased a mailing list of 2,000 names and addresses for her mail order business, but after scanning the list she doubts the authenticity of the list. She randomly selects five names from the list for validation. If 40% of the names on the list are non-authentic, and x is the number on non-authentic names in her sample, the expected (average) value of x is ______________.
a) 2.50
b) 2.00
c) 1.50
d) 1.25
e) 1.35
Answer:
b) 2.00
Step-by-step explanation:
For each name, there are only two possible outcomes. Either it is authentic, or it is not. The probability of a name being authentic is independent of any other name. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
She randomly selects five names from the list for validation.
This means that [tex]n = 5[/tex]
40% of the names on the list are non-authentic
This means that [tex]p = 0.4[/tex]
The expected (average) value of x is
[tex]E(X) = np = 5*0.4 = 2[/tex]
The correct answer is given by option B.
X is inversely proportional to y, and x = 18 when y = 4. find x when y is 30
Answer:
X= 2.4
Step-by-step explanation:
x = k/y............eqn1
18= k/4
k= 18×4
k= 72
Using the first equation
x= 72/30
x= 2.4

Tell whether the question is a statistical question. Explain.
Part 1
Answers:
Statistical questionNot a statistical questionStatistical question==========================================
Explanations:
The phrasing here is a bit vague, but I think your teacher means "your" in the sense that it is directed at whoever is taking the survey and not a specific single person. If it was directed at exactly one person, and one person only, then no statistics are needed. You can simply count the number of songs on the device and that's the end of that story. However, when it comes to multiple people, statistics is used to give an idea of how the population is overall. Recall that the sample is supposed to represent the population, assuming no biases are present. I'll assume that your teacher is aiming for the more broader definition of "your" and that's why this is a statistical question. Similar reasoning will apply for problem 3.Unlike problems 1 and 3, this is not a statistical question. Why not? Because we know exactly how many feet are in 1 yard, and that will not change no matter what happens. It's simply a definition we set up earlier, and have stuck to. Having it change won't help things. Statistical questions address variables in which not only are allowed to change, but do so randomly (according to some pattern). Here we have 3 feet to a yard and no statistics are needed to address this.Similar to problem 1. I'm assuming your teacher is asking a broader audience and not exactly one single specific person. In this case, the name of the favorite movie would be considered qualitative categorical data, and also considered nominal as well. We don't have ordinal data because movies cannot be ordered or ranked, as that is subjective. I'm not considering alphabetical order. We have a statistical question here for the broader audience because the variable "favorite movie" is allowed to change, and is subject to some degree of randomness. Hence the phrasing "random variable".Answer:
multiply the length value by 3
so its 3 foot

A car bought for $22,959 depreciates at 12% annually. What is its value after 7 years?
Answer:
After 7 years the car will be worth $ 9,382.78.
Step-by-step explanation:
Given that a car bought for $ 22,959 depreciates at 12% annually, to determine what is its value after 7 years, the following calculation must be performed, using exponential expressions to determine the price decrease:
100 - 12 = 88
22,959 x 0.88 ^ 7 = X
22.959 x 0.4086 = X
9,382.78 = X
Therefore, after 7 years the car will be worth $ 9,382.78.
