PLEASEE HELP ILL MARK BRAINLIEST

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.

Just answering this for that you can mark brainliest the person who answered right :-) and sorry for my English lol

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.

[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]

Since 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]

We 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.

Answer:

6

Step-by-step explanation:

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

Answer:D

Step-by-step explanation: The sides should be 6.633 to have an area of 44in squared so that cancels out 11 and 7 and 6.5 because 11 and 7 are higher than 6 and 6.633 and they said exactly 6.5 which is obviously wrong.

Give the man brainliest: Oh wow look at that they added a new area where I can convince you to give me brainliest. I deserve brainliest because shaggy is my best friend and if I don't get brainliest he'll destroy you using 1% of his power.

Answer:

387 km

Step-by-step explanation:

The length of AC, b can be obtained using the cosine rule ; using the cosine relation:

b² = a² + c² - 2ac CosB

b² = 250² + 185² - 2(250*185) Cos125

b² = 62500 + 34225 - 92500 * −0.573576

b² = 96725 + 53055.820

b² = 149780.82

b = sqrt(149780.82)

b = 387.01527

b = 387 km (nearest whole number)

Step-by-step explanation:

HERE,

lenth=12m.m.

breadth=9m.m.

so,

Area of rectangular =[tex]\boxed{\underline{\underbrace{\mathcal\color{gold}{length×breadth }}}}[/tex]

so

Area=9×12=[tex]\tt{ 108m.m^2 }[/tex] ⠀

Answer: Ok, so I am really good at finding the degree of polynomials... So the answer is D. Good luck! Hope this helps. :)

Answer:

12

Step-by-step explanation:

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

Answer:0.50 cents

Step-by-step explanation: do $6.50 -5.00 which gives you $1.50 .Next divide 1.50 by 3 which gives you 0.5 which is 0.50 cents.

Hope it helps

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)
