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.
PLEASE HELP PLEASEEEEE
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.
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.

Six friends ate in a restaurant together and split the total cost, c, equally. Each person paid less than $8.
Which statements represent the scenario? Check all that apply.
The total cost of the food, c, can be represented by the inequality StartFraction c Over 6 EndFraction less-than 8.
The total cost of the food could be $48.
The total cost of the food could be $36
.
When graphed, the number line would be shaded to the left of the maximum value.
The total cost of the food must be greater than $60.
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)

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

Okay so this question is quite simple all we have to do is take away 1/3 from each candy bar and count how many 1/3rds there are in all 4 candy bars.
This is very simple all we have to do is add 3 + 3 + 3 + 3 or 3 x 4
If you multiply 3 by 4 you get 12.
So, in conclusion, 12 people could get 1/3 of Joannas' 4 candy bars
