Answer 1

Answer:

It is not a function

Step-by-step explanation:

This is not a function because it does NOT pass the vertical line test. The vertical line test is just as it sounds: if you were to draw a vertical line from 3 to -3, it would pass through two outputs for every one input. Therefore, it's not a function.

Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are

female, so he selected a random sample of 500 of Katy Perry's followers. In the

sample, 308 are female. Construct and interpret a 90% confidence interval for the

true proportion of Katy Perry followers that are female.

Answers

Answer and Step-by-step explanation:

To calculate a confidence interval for a proportion:

1) Determine the proportion

[tex]p=\frac{308}{500}[/tex]

p = 0.616

2) A 90% confidence interval has z-score that is 1.645.

3) Calculate margin of error

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

where

n is the sample size

So

[tex]ME=\sqrt{\frac{0.616(1-0.616)}{500} }[/tex]

[tex]ME=\sqrt{\frac{0.616(0.384)}{500} }[/tex]

ME = 0.02175

Then the interval is given by

p ± z(ME)

0.62 ± 1.645(0.02175)

0.62 ± 0.035

The interval will be

0.585 < p < 0.655

What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.

Solve for x your answer must be simplified. -4+x<9

Answers

Answer:

x<13

Step-by-step explanation:

To solve this, we want to have the isolate the variable x on the left side, by itself without a coefficient. All we have to do to do this is add 4 to both sides, cancelling out the -4 and getting x<13

Answer:

x = 13 + y

Step-by-step explanation:

Simplify:

-4 + x = y + 9

Reorder the terms:

-4 + x = 9 + y

Move all terms containing x to the left all other terms to the right

Add 4 to each side of the equation

-4 + 4 + x = 9 + 4 + y

Combine like terms: -4 + 4 = 0

0 + x = 9 + 4 + y

x = 9 + 4 + y

9 + 4 = 13x = 13 + y

Answer:

x = 13 + y

A juice box has 20% more juice in its new packaging.
The original packaging held 12 fluid ounces. How
much juice does the new packaging hold?
Whose double number line is correct?EXPLAIN YOUR THINKING!!!!!!!

Answers

Answer:

Abdullah is correct.

Step-by-step explanation:

The bottle contained originally 12 fl oz, so 12 fl oz is 100%.

The box now contains 20% more, so now it contains 120% of 12 fl oz.

120% * 12 fl oz = 1.2 * 12 fl oz = 14.4 fl oz

Also, 20% is 1/5. Abdullah divided 12 oz into 5 equal parts, and then he added one more 1/5. He interpreted the problem correctly. The amount in the new bottle is the amount of the old bottle plus 20% of that old amount.

Kanna considers the original amount to be 80%. When he adds another 20%, he is adding 1/4 of 12 which is too much. That is why he gets an incorrect answer that is to high. He interpreted the problem incorrectly. For him, the old bottle has 20% less than the new bottle. That is incorrect.

Abdullah is correct.

2. Given the equation of a circle in standard form, identify the center, radius, and graph the circle.
(x + 1)2 + (y - 2)2 = 36

Center:
Radius:

Answers

Answer:

Center: ( -1 , 2 )

Radius: 6

Step-by-step explanation:

The equation for a circle is given as follow:

[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]

Where,

the Center is: ( h , k ) (note that the signs of the number are different)

and the radius is: r

So if we compare the original circle equation to the equation in the question we can see that:

[tex](x+1)^{2} +(y-2)^{2} =36[/tex]

the Center is: (-1,2)

and the radius is: [tex]\sqrt{36}[/tex] = 6

2. To draw the graph find points that lay on the circle, it's better to take the values of x and y from the Center:

first sub y=2 in the equation to find the values for x:

[tex](x+1)^{2} +(y-2)^{2} =36[/tex]

[tex](x+1)^{2} +(2-2)^{2} =36[/tex]

[tex](x+1)^{2} +(0)^{2} =36[/tex]

[tex](x+1)^{2} =36[/tex]

[tex]x+1 =±\sqrt{36}[/tex]

[tex]x=6-1[/tex]    AND    [tex]x=-6-1[/tex]

[tex]x=5[/tex]          AND    [tex]x=-7[/tex]

The points are A(5,2)  and  B(-7,2)

second sub x= -1 in the equation to find the values for y:

[tex](x+1)^{2} +(y-2)^{2} =36[/tex]

[tex](-1+1)^{2} +(y-2)^{2} =36[/tex]

[tex](0)^{2} +(y-2)^{2} =36[/tex]

[tex](y-2)^{2} =36[/tex]

[tex]y-2=±\sqrt{36}[/tex]

[tex]y=6+2[/tex]    AND    [tex]y=-6+2[/tex]

[tex]y=8[/tex]          AND    [tex]y=-4[/tex]

The points are D(-1,8)  and  E(-1,-4)      

After finding the points write them in the graph and match them together to get the like the circle in the picture below:

Benita buys 2 shirts for the same price, s. The sales tax rate is 6.5%.


Write an expression to represent the total cost of the shirts in two different ways.


Enter the correct answers in the boxes.

Answers

Answer:

2S + 0.065(2S)

Step-by-step explanation:

Since S is the price of a shirt, the price of two shirts would be 2 x S = 2S

a tax is a compulsory sum levied on goods and services. tax increases the price of a good

The price of the 2 shirts would increase by the amount of tax ; 0.065(2S)

This gives = 2S + 0.065(2S)

Alternatively, since two shirts were purchased, the amount of tax would be twice 0.065 - 0.13 - S + S + 0.13S

We want to write two expressions that represent the total cost of the shirts, the expressions are:

Cost = P*(1.065) +  P*(1.065)

cost = P*2.13

We know that Benita buys two shirts for the same price, P.

Then at this moment. the total cost is just:

cost = 2*P

Now we apply a 6.5% tax, then the price increases by 6.5%, this is written as:

P' = P*(1 + 6.5%/100%) = P*(1.065)

Then the total cost is twice that amount, written as:

Cost = P*(1.065) +  P*(1.065)

This can be one of the two expressions.

Now to get the other expression, we just simplify the above one:

cost = 2*P*(1.065) = P*2.13
