Compare the proportional relationships. Which represents the greatest price per pound of walnuts

Answer:

-3

Step-by-step explanation:

We have to find the difference:

We start with 5 yellow counters

Since we have to subtract more yellow counters than we have (5 instead of 8), we add 3 zero-pairs:

We subtract the 8 yellow counters:

We are left with 3 red counters, which means the result is -3

Answer:

288 Miles

Step-by-step explanation:

Solve for x (speed)

5.5x = 264

Divide by 5.5

x = 48

y = 48x

Subsitute 6 hours in for x

y = 48(6)

y = 288

Answer: Allie went 288 miles in 6 hours.

Step-by-step explanation:

First, you must find out how many miles Allie travled in one hour

= 264/5.5

= 48

Next, multiply the quotient by the number of hours to get the answer.

= 48 x 6

= 288

Answer:

We can check this two ways: distributing the -0.5, and plugging in a number for x.

First, we can check this by distributing the -0.5.  Our equation becomes:

-1.5x -2.5 = -1.5x + 2.5

Clearly, this is not true.  We can show this one more time by plugging in a number for x.  I will use 2.

Now, we evaluate both sides and see if they are equal.

-3 - 2.5 = -3 + 2.5

-5.5 = 0.5

Clearly, this is not true.  These expressions are not equivalent.

Step-by-step explanation:

Answer:

Step-by-step explanation:   Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

Answer:

1 oz

Step-by-step explanation:

Given that:

% solution of super grow fertilizer = 10%

To obtain mixture of 36oz of a 12.5% concentration

Let oz of pure supergrowth to be added = s

(Initial % * (36 - s) + s) / 36 = target concentration

(10% * (36 - s) + s) / 36 = 12.5%

(0.1(36 - s) + s) / 36 = 0.125

Cross multiply:

0.1(36 - s) + s =. 0.125 * 36

3.6 - 0.1s + s = 4.5

3.6 + 0.9s = 4.5

0.9s = 4.5 - 3.6

0.9s = 0.9

s =. 0.9/0.9

s = 1

Hence, 1 oz of pure supergrowth should be added to the 10% solution to get 36 oz of a 12.5% concentration.

Answer:

1/2 liters

Step-by-step explanation:

Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 1 1/2 - 1/4

= 3/2 - 1/4

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2

Hence the quantity of lemonade that Rosanne brother drinks is 1/2 liters

Answer:

1/2 liters

Step-by-step explanation: Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2

Step-by-step explanation:

Answer:

a

 [tex]E(Z) =  202 [/tex]  

b

[tex]E(Z) = 198[/tex]

c

[tex]E(Z) = -140  [/tex]

Step-by-step explanation:

From the question we are told that

   The mean of X  is [tex] E(X)  =  20[/tex]

   The standard deviation of X is  [tex]s_1 = 5[/tex]

   The mean of Y  is [tex]\= y  =  40[/tex]

    The standard deviation of Y is  [tex]s_2 = 10[/tex]

Considering question a  

Generally the mean of   Z = 2 + 10X. is mathematically  represented

    [tex]E(Z) = E[2 + 10X ][/tex]

=> [tex]E(Z) =  2 +  10 E(X)[/tex]

=>  [tex]E(Z) =  2 +  10 * 20 [/tex]        

=>  [tex]E(Z) =  202 [/tex]          

Considering question b

Generally the mean of   Z = 10X - 2.. is mathematically  represented  

        [tex]E(Z) = E[10X -2 ][/tex]

   => [tex]E(Z) = 10E(X) - 2[/tex]

  =>  [tex]E(Z) = 10* 20  - 2[/tex]

  =>  [tex]E(Z) = 200  - 2[/tex]

 =>  [tex]E(Z) = 198[/tex]

Considering question c

Generally the mean of   -3X - 2Y is mathematically  represented

     [tex]E(Z) = E[-3X -2Y ][/tex]

     [tex]E(Z) = -3 E(X) -2E(Y) [/tex]

=>   [tex]E(Z) = -3 * 20 -2* 40 [/tex]

=> [tex]E(Z) = -140  [/tex]

that's the answer. good luck

Answer:

Piecewise functions are functions that behave differently in different regions of the domain.

One example that you may see in your city is the case of the street illumination, such that can be modeled as:

x = time

Suppose that the lights are turned on at a given hour x0 and then turn off at the hour x1, we can define:

f(x) = 0 if x1 < x < x0

f(x) = 1 if x0 ≤ x ≤ x1

Where f(x) represents the intensity of the light at the time x.

Between x1 and x0, the lights are not working, so the illumination that they provide is zero.

Between x0 and x1 the lights are turned on, so the illumination is 1.

Another example can be the accurate description of the velocity of a car as a function of time.

For some pieces, the car will be stopped (maybe in a red light)

For some pieces, the car will be moving slow (maybe there is a lot of traffic)

For some pieces, the car will be moving fast or accelerating (in an empty street).

So we can define this motion as a piecewise function that obviously will depend on how the car moves.

Answer:

The p-value is  [tex]p-value = 0.0039854[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 1100

   The population proportion is  p = 0.50

  The sample proportion is  [tex]\^ p = 0.54[/tex]

The null hypothesis is  [tex]H_o : p = 0.50[/tex]

The alternative hypothesis is [tex]H_a : p > 0.50[/tex]

 Generally the test statistics is mathematically represented as

     [tex]z = \frac{\^ p - p }{ \sqrt{\frac{ p(1 - p)}{n} } }[/tex]

=>   [tex]z = \frac{ 0.54 - 0.54 }{ \sqrt{\frac{ 0.50 (1 - 0.50)}{1100} } }[/tex]

=>  [tex]z = 2.6533[/tex]

Generally from the z-table the probability of 2.6533 for a right tailed test is  

         [tex]p-value = 0.0039854[/tex]

Answer:

6

Step-by-step explanation:

A way to answer these questions like I usually do is to subtract the result by the number you already know, like this;    10-4=6, so 6 would be what X equals, or you can just take the long way and keep guessing what the answer would be and keep doing the problems, but that would be very time consuming so I would recommend just doing the subtraction method!

Hope this helps!

Correct question is;

The terminal side of angle θ intersects the unit circle in the first quadrant at (9/25,y). What are the exact values of sinθ and cosθ?

Answer:

sinθ = (√544)/25) and cosθ = 9/25

Step-by-step explanation:

We are given that (9/25,y) lies on the unit circle. Thus, from general representation of equation of a circle, we can write that;

(9/25)² + y² = 1²

y² = 1 - (9/25)²

y² = (625 - 81)/25²

y² = 544/25²

y = ±(√544)/25

We are told the point is in the first quadrant and so we will choose the positive value of y = (√544)/25.

Therefore, the terminal side of the angle θ intersects the unit circle at [9/25, (√544)/25)]

In unit circle geometry, cosθ = x, while sinθ = y.

Thus; sinθ = (√544)/25) and cosθ = 9/25

The exact value of [tex]sin\theta[/tex] and [tex]cos\theta[/tex] is  [tex]cos\theta = \frac{9}{25} , sin\theta = \frac{\sqrt{544} }{25}[/tex] and this can be determined by forming the equation of circle.

Given :

The terminal side of angle [tex]\theta[/tex] intersect at unit circle ([tex]\frac{9}{25}, y[/tex]).

From general representation of equation of circle , we can write

[tex]x^{2} + y^{2} = a^{2}\\[/tex]

[tex](\frac{9^{2} }{25^{2} })[/tex] + [tex]y^{2} = 1^{2}[/tex]

[tex]y^{2} = 1 - \frac{81}{625}[/tex]

[tex]y^{2} = \frac{625-81}{625}[/tex]

[tex]y^{2}=\frac{544}{625}[/tex]

Taking square root both sides

[tex]y= \frac{\sqrt{544} }{\sqrt{625} }[/tex]

[tex]y = \frac{\sqrt{544} }{25}[/tex]

We are taking only because point  lies in first quadrant.

The terminal side of angel [tex]\theta[/tex] unit circle in first quadrant at [tex](\frac{9}{25} , \frac{\sqrt{544} }{25})[/tex]

In unit circle

[tex]x = cos\theta , y = sin\theta[/tex]

[tex]\rm cos\theta = \frac{9}{25} , sin\theta = \frac{\sqrt{544} }{25}[/tex].
