Answer: B) [-0.0332,0.1332]

Step-by-step explanation: Confidence Interval is an interval where we can be a percentage sure the true mean is.

The confidence interval for a difference in population proportion is calculated following these steps:

First, let's find population proportion for each population:

[tex]p_{1}=\frac{30}{120}=0.25[/tex]

[tex]p_{2}=\frac{32}{160}=0.2[/tex]

Second, calculate standard deviation for each proportion:

[tex]\sigma_{1}=\sqrt{\frac{0.25(0.75)}{120} } = 0.0395[/tex]

[tex]\sigma_{2}=\sqrt{\frac{0.2(0.8)}{160} } = 0.0316[/tex]

Now, we calculate standard error for difference:

[tex]SE=\sqrt{\sigma_{1}^{2}+\sigma_{2}^{2}}[/tex]

[tex]SE=\sqrt{0.0395^{2}+0.0316^{2}}[/tex]

SE = 0.0505

The z-score for a 90% CI is 1.645.

Then, confidence interval is

[tex]p_{1}-p_{2}[/tex] ± z-score.SE

[tex]0.25-0.2[/tex] ± [tex]1.645(0.0505)[/tex]

0.05 ± 0.0831

The limits of this interval are:

inferior: 0.05 - 0.0831 = [tex]-0.0332[/tex]

superior: 0.05 + 0.0831 = 0.1332

The 90% confidence interval for the difference in the population proportion of pit pulls and golden retrievers is [tex][-0.0332,0.1332][/tex].

Answer:

5 nickels

10 dimes

5 quarters

Step-by-step explanation:

n = number of nickels

d = number of dimes

q = number of quarters

q = n

d = 2n

0.05n + 0.10d + 0.25q = 2.50

substitute

0.05n + 0.10(2n) + 0.25(n) = 2.50

0.05n + 0.20d + 0.25n = 2.50

0.50n = 2.50

n = 5

d = 10

q = 5

F(x)=3^3 + 5(3)^2 +1

F(x)=27 + 5(9) +1

Answer:

145

Step-by-step explanation:

Assume the number of sword tails is x. Then the number of guppies is 4x.

After 23 guppies and 27 swordtails were added. Then guppies = 4x+ 23

swordtails = x+27

According to the relation 83 more guppies than swordtails. We can obtain:

[tex]4x + 23 = x + 27 + 83[/tex]

4x-x= 27+83-23

3x=110-23

3x=87

x=29

There are 5x fish in total at first.

5x=5*29=145

so the number of fish in the shop at first is 145

(-1, 2)

Step-by-step explanation:

Answer:

Her error was that 1 and 9/8 are not equal. 9/8 is 1/8 larger than 1 is, and therefore can not be equivalent to 1.

On the number line 9/8 and 1 are not equal, since 9/8 =1.125 which is greater than 1.

A number line is a visual representation of numbers on a straight line. This line is used to compare numbers that are placed at equal intervals on an infinite line that extends on both sides, horizontally or vertically.

Given that, on the number line Andrea Drew marked 9/8 and 1 and she said  that they are equal.

Here, 9/8 =1.125

1.125>1

Therefore, on the number line 9/8 and 1 are not equal, since 9/8 =1.125 which is greater than 1.

Step-by-step explanation:

Standard deviation is 57

Middle 50% is average and one standard deviation to each direction

So if the average is 174

174 - 57 is 117

174 + 57 is 231

Answer:

    [tex]\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}[/tex]

Step-by-step explanation:

Step(i):-

Given

        sin xy = x² + 2xy ...(i)

Apply

       [tex]\frac{d}{dx} UV = U^{l} V + U V^{l}[/tex]

     [tex]\frac{d}{dx} x^{n} = nx^{n-1}[/tex]

Differentiating equation (i) with respective to 'x', we get

      [tex]cosxy \frac{d}{dx} (xy) = 2x + 2( x\frac{dy}{dx} + y(1))[/tex]

      [tex]cosxy (x\frac{dy}{dx} +y(1)) = 2x + 2( x\frac{dy}{dx} + y(1))[/tex]

     [tex]cosxy (x\frac{dy}{dx}) + ycosxy = 2x + 2( x\frac{dy}{dx}) +2 y)[/tex]

   [tex]cosxy (x\frac{dy}{dx}) - 2( x\frac{dy}{dx}) = 2x +2 y- ycosxy[/tex]

   [tex](cosxy-2) (x\frac{dy}{dx}) = 2x +2 y- ycosxy[/tex]

       [tex]\frac{dy}{dx} = \frac{2x +2 y- ycosxy}{x(cosxy-2)}[/tex]

Answer:

Step-by-step explanation:

The formula of slope from 2 points is change in y divided by change in x, so you can apply that to this problem.

First, find the change in y between the two points. To do this, do y2 - y1.

y2 = 6 and y1 = 2, so you have 6 - 2 = 4.

Next, find the change in x between the two points. To do this, do x2 - x1.

x2 = 5 and x1 = 3, so you have 5 - 3 = 2.

All you're really doing here is finding the distance between the x values and the y values of the points, if that makes sense.

The last step is to do change in y divided by change in x, so 4 / 2 = 2.

This means that the slope of the line is 2.
