Valeria already owns 147 necklaces, and additional necklaces are priced at 2 for a dollar. How
much money does Valeria need to spend on new necklaces in order to own a total of 477
necklaces? Write and solve an equation to find the answer
Answer:
$660
Step-by-step explanation:
Step 1
The number of extra necklaces that valeria needs is calculated as:
477 necklaces - 147 necklaces
= 330 necklaces
Step 2
We are told that
1 extra necklace cost $2
Hence
1 necklace = $2
330 necklaces = x
Cross Multiply
x = 330 × $2
x = $660
Therefore, Valeria need to spend and additional $660

Describe the graph of this inequality: 2x + 3 > 9
Answer:
Open circle at 3 going to the right.
Step-by-step explanation:
Let’s look at this.
first, let’s simplify the inequality. 2x +3-3>9-3
2x>6
x>3
since this is just a greater than or less than, it will be an open circle.
now that we have established that, we can see that x is BIGGER than 3. In that case, it will be an open circle at 3 going to the right.

In chapter 1, we introduced several sampling methods: Simple random sample, stratified sampling, systematic sampling, and cluster sampling. All the sampling methods except for convenience sampling, allow for unbiased statistical inference to be made. Convenience sampling typically leads to an unrepresentative sample and biased results. In this week's discussion board, you are asked to design a sample that is representative of the population and unbiased. Scenario: A marketing executive for Coca- Cola, Inc. wants to identify television shows that people in the Seattle area who typically drink Coke are watching. The executive has a list of all households in the Seattle area. Task: You are asked to design a sample to obtain the individuals in the sample. Use the provided scenario to help the Coca-Cola executive identifying the television shows. Design a sample that meets the requirements we discussed in the previous chapter. You need to explain why did you choose this sampling method.
Answer:
For the coca-cola case, stratified sampling coupled with random sampling will be used.
Step-by-step explanation:
Before going into discussing the scenario, it is evident to discuss the properties of mentioned sampling methods. They are as follows:
Random sampling as the name indicates is purely by randomness. It is a sample in which each element of the population has an equal chance of coming on.
Systematic sampling is easier than random sampling. Here all the elements are arranged in an order and the kth element is considered after a specific interval.
Cluster Sampling is another type of sampling where the population is divided into groups probably on the basis of their geographical location and all the elements of the cluster are then used.
Stratified Sampling is a two-step sampling method where firstly the population is divided into strata, groups on basis of some characteristic, like gender, age, and then another sampling method as the random or systematic method is chosen to pick samples from each of these strata.
On the basis of properties presented and the scenario outlined, it is evident that the population will be divided into strata based on age, gender, profession, and education, and then a random sampling within each stratum is used for all the population of the Seattle area.

Step-by-step explanation:
Henri puts aside $10 cash every month in a shoebox. He also makes a one-time deposit of $1,500 in a savings
account at 9% annual interest, compounded yearly,
Amount of shoebox savings: f(t) = 120t
Amount of savings account: g(t) = 1,500(1.09)^t
Which function represents the amount of money Henri will have after t years?
Answer:
T(t) = f(t) + g(t)
Step-by-step explanation:
The function which represents the total amount of money Henri will have in t years is the function obtained using an addition operation in the two defied functions, f(t) and g(t) ; total amount saved in shoe box plus the total compounded amount in savings account
Total amount of money in t years, T(t) ;
T(t) = 120t + 1,500(1.09)^t
f(t) = 120t
g(t) = 1,500(1.09)^t
Hence,
T(t) = f(t) + g(t)
What is the slope of the line that passes through the points (-5, 8) and (-11, 8)
Find the equation to the line below .
Answer:
y = 4x + 1
Step-by-step explanation:
y = mx + b
The line goes thru (0, 1) and (1, 5)
The slope = m = (5 - 1)/ 1 - 0) = 4/1 = 4
The y-intercept is (0, 1), so b = 1
y = 4x + 1 is the equation of the line

The equation y =f(x) is graphed on the coordinate plane. A function, g(x). is the result of translating the graph of fuxi to the left 2 units and up 4 units. Which is an equation for g(x)?
A)g(x)=f(x - 2)+4
B)g(x) = f(x + 2) + 4
C)g(x)=f(x-4)-2
D)g(x)=f(x + 4)-2
Answer:
A
Step-by-step explanation:
g
[tex]g(x) = f(x - 2) + 4[/tex]
A function assigns the value. The equation of the function g(x) will be f(x-2)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x) is a function which is shifted two units to the right and 4 units upwards. Therefore, in the function f(x) we need to add -2 to the value of the x for the function to move right, while we need to add 4 to the overall function to move it four units upwards.
Hence, the equation of the function g(x) will be f(x-2)+4.

A scientist claims that 6% of viruses are airborne. (a) If the scientist is accurate, what is the probability that the proportion of airborne viruses in a sample of 529 viruses would be greater than 8%? Round your answer to four decimal places.
Answer:
Probability that the proportion of airborne viruses in a sample of 529 viruses would be greater than 8% is 0.9545.
Step-by-step explanation:
For the given population the distribution of air-borne viruses is given as 6%. Now for this the value of Z score is given as
[tex]Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}[/tex]
Here
[tex]\hat{p}[/tex] is the sample measure which is 8% or 0.08p is the population measure which is 6% or 0.06n is the number of samples which is 529So the Z score is given as
[tex]Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}\\Z=\dfrac{0.08-0.06}{\sqrt{\dfrac{0.08(1-0.08)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.08(0.92)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.0736}{529}}}\\Z=\dfrac{0.02}{0.01179}\\Z=1.6955[/tex]
For this the score, the value of probability is calculated from the table as below:
[tex]P(\hat{p}>0.08)=p(Z>1.6955)\\=1-p(Z<-1.6955)[/tex]
Here value of p(Z<-1.6955) is given as 0.0455
[tex]P(\hat{p}>0.08)=p(Z>1.6955)\\P(\hat{p}>0.08)=1-p(Z<-1.6955)\\P(\hat{p}>0.08)=1-0.0455\\P(\hat{p}>0.08)=0.9545[/tex]
What is the probability that you will get “heads” no more than once out of 3 flips?
P(0 successes) + P(1 success) =
Given:
Three coins are tossed.
To find:
The probability that you will get “heads” no more than once out of 3 flips.
Solution:
If three coins are tossed then the sample space is:
[tex]S=\{HHH,HTH,HHT,HTT,THH,TTH,THT,TTT\}[/tex]
Total possible outcomes = 8
Number of 0 successes means 0 heads in 3 flips, i.e., TTT.
Number of 1 successes means exactly 1 heads in 3 flips, i.e., HTT, THT, TTH.
Now,
[tex]P(0\text{ success})=\dfrac{1}{8}[/tex]
[tex]P(1\text{ success})=\dfrac{3}{8}[/tex]
And, their sum is:
[tex]P(0\text{ success})+P(1\text{ success})=\dfrac{1}{8}+\dfrac{3}{8}[/tex]
[tex]P(0\text{ success})+P(1\text{ success})=\dfrac{4}{8}[/tex]
[tex]P(0\text{ success})+P(1\text{ success})=\dfrac{1}{2}[/tex]
Therefore, the probability that you will get “heads” no more than once out of 3 flips is [tex]\dfrac{1}{2}[/tex].
