=>w=1.2 x 0.6/1.6
=>w=0.45
Does this sample support a claim that more than 10% of job applicants in California test positive for drug use
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attached file.
Let p become a screen positive for substance use throughout California
To test [tex]H_0 : p = 0.1_{against} \ H_0:p>0.1[/tex]
In California, [tex]\hat{P}[/tex] is a good test for medication and n seems to be the random sample.
The stats of the examination are given
[tex]\to z=\frac{\hat{p} -0.1}{\sqrt{\frac{0.1 \times 0.9}{n} }}_{\ that \ is \ under H_o \ follows \ a \ normal \ distribution}.[/tex]
They reject [tex]H_o \ at \ 5\%[/tex] if it's relevant:
[tex]\to |Z_{obs} |> Z_{0.05}\\\\Here\\\\ \to \hat{p} = \frac{145}{1200} = 0.121 \\\\ \to n = 1200\\\\ \to z_{obs} = 2.42487\\\\ \to Z_{0.05} = 1.64485[/tex]
[tex]\to z_{obs} = 2.42487 > z_{0.05}= 1.64485[/tex]
We, therefore, refuse [tex]H_o \ at \ 5\%[/tex] level and we can infer that such a test supports an argument which Upwards of 10% of California jobseekers screen positive for use of medicines.
A store in Melrose, Massachusetts advertised a 35-mm camera for $259.99 and a wide-angle lens for $89.99. What is the total purchase price if the state sales tax rate is 6 percent
Answer:
The total purchase price is $370.97.
Step-by-step explanation:
Given;
price of the 35-mm camera, = $259.99
price of the wide-angle lens = $89.99
TAX rate = 6% = 0.06
The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)
The total purchase price = $20.99 + 349.98
The total purchase price = $370.97
Therefore, the total purchase price is $370.97.

In a certain town, 23% of males have a beard. In random samples of 25 men from
this town, what are the mean and standard deviation of the number of men with
a beard?
Answer:
Mean μ = 5.75
Standard deviation σ = 2.1041
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 25
Given proportion p= 23% = 0.23
Let 'X' be the random variable in a binomial distribution
Mean μ = np = 25 × 0.23 = 5.75
Step(ii):-
Standard deviation
σ = √npq
σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]
σ = 2.1041

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 5−x and y = 2x + 1 intersect are the solutions of the equation 5−x = 2x + 1.
Part B: Make tables to find the solution to 5−x = 2x + 1. Take the integer values of x between −3 and 3.
Part C: How can you solve the equation 5−x = 2x + 1 grap hically?
Answer:
y = 5 - x → standard form y = -x + 5
y = 2x + 1
A: If two sides of an equation are set equal to each other, their value is a point of intersection because they will both equal a certain value.
B:
3 → 5 - 3 = 2(3) + 1 → 2 = 6 + 1 → 2 ≠ 7
2 → 5 - 2 = 2(2) + 1 → 3 = 4 + 1 → 3 ≠ 5
1 → 5 - 1 = 2(1) + 1 → 4 = 2 + 1 → 4 ≠ 3
0 → 5 - 0 = 2(0) + 1 → 5 = 0 + 1 → 5 ≠ 1
-1 → 5 - (-1) = 2(-1) + 1 → 6 = -2 + 1 → 6 ≠ -1
-2 → 5 - (-2) = 2(-2) + 1 → 7 = -4 + 1 → 7 ≠ -3
-3 → 5 - (-3) = 2(-3) + 1 → 8 = -6 + 1 → 8 ≠ -5
algebraically ↓
-x + 5 = 2x + 1 → 4 = 3x → x = 4/3
C: graphically
graph both equations and find point of intersection
We know these points are the solutions to [tex]5-x=2x+1[/tex] because by setting the two equations equal to each other, we find where they intersect, and those points are the solutions to the equation.
Part B[tex]\begin{array}{|c|c|c|c|}\cline{1-4}\bf x&\bf5-x&\bf2x+1&\bf5-x=2x+1\\\cline{1-4}-3&8&-5&8\neq-5\\\cline{1-4}-2&7&-3&7\neq-3\\\cline{1-4}-1&6&-1&6\neq-1\\\cline{1-4}0&5&1&0\neq1\\\cline{1-4}1&4&3&4\neq3\\\cline{1-4}2&3&5&3\neq5\\\cline{1-4}3&2&7&2\neq7\\\cline{1-4}\end{array}[/tex]
Part B and a halfSince none of those values are correct solutions, let's solve this equation algebraically, even though the question doesn't ask for us to do so.
[tex]\begin{aligned}5-x&=2x+1\\-x&=2x+1-5\\-x-2x&=1-5\\-3x&=-4\\x&=\boxed{\frac{4}{3}}\end{aligned}[/tex]
Part CWe can solve the equation graphically by graphing both [tex]y=5-x[/tex] and [tex]y=2x+1[/tex], then finding where they meet. This is shown in the attachment below.

The two quantitative elements of process variation are: Select one: a. common cause and special cause b. median and variance c. central tendency and spread d. inspection and detection
Answer:
The two quantitative elements of process variation are:
a. common cause and special cause.
Step-by-step explanation:
When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred. Thus, process variation is a leading cause of quality issues. There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system. Process variations can be reduced by reducing the common and special cause variations, among other steps.
Determine if (1, 3) is a solution to the given system of linear equations. 5x+y=8 x+2y=5
Answer:
No, because substituting the given ordered pair doesn't yields two true expressions
Step-by-step explanation:
5x + y = 8
5 + 3 = 8 so thats correct
x + 2y = 5
1 + 6 =7, not 5
so only 1 is correct
If you start a bank account with $100 and you deposit $25 each month, what equation
correctly represents this situation?
Step-by-step explanation:
so you start with $100
every month you get $25
so you could call $25 n
so every month you get n added to the bank account
so you could call the $100 s (which represents start)
and do s+n for every month and if you need to show that for a year then:
s+(nx12)
what is the solution to the system of equations
Answer:
Infinitely many solutions
Step-by-step explanation:
These equations are the same. The only difference being one is written in fractions and the other is in decimals. Since they are the same, they will have infinitely many solutions.

Simplify sin θ/cosθ tan θ to a number or a single trigonometric function
Answer:
The answer is below
Step-by-step explanation:
Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.
Some trigonometric identities are:
secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.
Hence simplifying the question:
[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]
You charge 2500 to a credit card. Use the compound interest formula to find the new amount you owe on your credit card after 6 months 20% APR compounded daily (assuming you don’t make any payments)
Answer: Well This is what 24% APR on a credit card is?
If you have a credit card with a 24% APR, that's the rate you're charged over 12 months, which comes out to 2% per month. Since months vary in length, credit cards break down APR even further into a daily periodic rate (DPR). It's the APR divided by 365, which would be 0.065% per day for a card with 24% APR.
