It is now 8:59 a.m. when the bell rings at 9:01 am. Damian will be late for science class for the 3rd time this week. He must get from one side of the school to the other by hurrying down 3 different hallways. He runs down the first hallway, a distance of 35.0 at a speed of 3.5 m/s. The second hallway is crowded with students and he covers its 4.80 m length at a speed of 1.20 m/s. The final hallway is empty and Damian covers its 60.0 m length at a speed of 5.00 m/s.
How long does it take him to cover the 1rst hallway? The second one? The third one?

Step-by-step explanation:

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.

Answer:

y=2x

...............mm.

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)

Answer:

no they arent

Answer:

no

Step-by-step explanation:

10/12 can be simplified as 5/6 however 20/32 turns to 10/16 which then can be simplified to 5/8

Answer:

w=0.45

Step-by-step explanation:

0.6/1.6=w/1.2

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.

Answer:

i think its DNE but im not sure... sorry

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:

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.

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: 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.

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.

Answer: (-1,3)

Step-by-step explanation:

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

Step-by-step explanation:

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]
