The water level of a river is 34 feet and is receding at a rate of 0.5 foot per day. Write an equation that represents the water

level, w, after d days. Identify the slope and y-intercept and describe their meanings. In how many days will the water level be 26 feet? Correct equation: The slope is . The y-intercept is . In days, the water level will be 26 feet.

W= -0.5d+34
The slope is -0.5 as the water I receding by .05 feet per days (d). The y-intercept is 34 as you start with 34 feet of water.

To find how many days it'll take for the water level to reach 26 feet you'll plug 26 in for w in this equation and then solve.

26= -0.5d +34
-8 = -0.5d
Minus 34 from both sides to get the slope alone. (As shown above.) Then divide by -0.5 to get d on it's own as shown below.
16 = d

It should take 16 days for the water to recede from 34 feet to 26 feet. You can plug 16 into the original equation to check your work.

artcher [175]

Step-by-step explanation:

x'=53

σ=16

n=144

a) hypothesis

H0:µ=55

Ha:µ<55

This is a left tailed test

b) Test statistics

  • z=(x'-u)/(sigma/sqrt {n})

=(53-55)/(16/sqrt{144})

=-1.5

c)Pvalue at z=|-1.5|

pvalue= p(z>1.5)

=1-0.933193

=0.066807

=0.0668

<u>Decision</u>

since pvalue>alpha(0.05) fail to reject the null hypotheis.

<u>Conclusion</u>

There is not sufficient evidence to support the claim the new computer program has not reduce the time to retrieve the data.

d)since Pvalue>alpha(0.025),so fail to reject the null hypothesis.

No, change in conclusion.

True.

You're allowed to move stuff around. Dogs of the AMS.

y' = 3y - 2x + 6xy - 1 \\&#10;y' = 3y + 6xy - 2x - 1 \\&#10;dy/dx= 3y(1 + 2x) - (2x + 1) \\&#10;dy/dx = 3y(1 + 2x) - (1 + 2x) \\&#10;\frac{dy}{dx} = (3y - 1)(1 + 2x) \ \Rightarrow\ \dfrac{dy}{3y-1} = (1 + 2x) dx

We wrote it in the form dy/dx = g(x) f(y) so this is separable.

Discuss three contributing factors that led to the human violations of human trafficking​
kenny6666 [7]

Answer:

Three contributing factors that led to human trafficking

Political instability, militarism, civil unrest, internal armed conflict and natural disasters may result in an increase in trafficking. The destabilization and displacement of populations increase their vulnerability to exploitation and abuse through trafficking and forced labour.

Step-by-step explanation:

its is 118.571428% so on repeating the digits to figure this out you just do

41.50*35 and you get 1.18571428 then you just move the decimal over 2 to the right.

A couple quick algebra 1 questions for 50 points!
kkurt [141]

Answer:

Question 6) Neither (Not an inverse variation)

Question 7) Inverse variation

Question 8) Inverse variation

Step-by-step explanation:

These are the two formulas we need to know prior to solving the question.

Direct variation: c times x

Inverse variation: c times 1/x --> c/x

- Here, c is the constant

6. y = x + 7

This is neither. It is not in the form of a direct, or inverse variation, so it does not belong in any category.

7. 14 = xy

This equation is an inverse variation.

xy = 14

y = 14/x

14 is the constant, and the format is the same as for an inverse variation.

8. x = -8/y

This equation is an inverse variation.

yx = -8

y = -8/x

-8 is the constant, and the format is the same as for an inverse variation.

So we can conclude that questions 7 and 8 is an inverse variations, while question 6 isn't.
