Which equation matches the table?

The interval which contains the median water bill is $200 - $225

The tabulated data :

Class interval ____ Frequency ___ Cummulative frequency

100 to 125, ________ 1 ___________ 1

125 to 150, 2 ______ 2 ___________3

150 to 175, 5 _______5 ___________8

175 to 200, 10 ______10 __________18

200 to 225, 13 _____13 __________ 31

225 to 250, _______ 8 __________40

The median class = Cummulative frequency / 2

The median class = 40 / 2

The class interval which contains the 20th frequency.

This is the 200 - 225 class

The interval which contains the median water bill is $200 - $225

Answer:

B

Step-by-step explanation:

In the slope intercept equation of the line the number that not multiplies the x or the y indicates where the line intercept the y axis

so in this cas the line intercept the y axis in the point (0,2)

so the answer is B

Actually Welcome to the concept of Parallel lines.

We must first understand that, Parallel Lines always have a same Slope, hence the 'm' value in y=mx+c equation will same, here it is '1/2' in the above equation,

so the points here are (-6,-17)

==>

(y-(-17)) = m(x-(-6))

==>

here m = 1/2 ,hence

y+17 = 1/2(x+6)

==> y+17 = 1/2(x) + 3

==> y = 1/2(x) + 3 - 17

==> y = 1/2(x) - 14

hence the Option 4.) is the correct answer!!

Answer:

95% confidence interval for the proportion of smokers who have tried to quit within the past year

(0.47956 ,0.50620)

Step-by-step explanation:

Step(i):-

Given that  National Center for Health Statistics interviewed 5409 adult smokers in 2015

Sample size 'n' = 5409

Given that 2666 of them said they had tried to quit smoking during the past year.

proportion

             [tex]P = \frac{x}{n} = \frac{2666}{5409} = 0.49288[/tex]

Step(ii):-

95% confidence interval for the proportion of smokers who have tried to quit within the past year

[tex]({P - Z_{0.05} \sqrt{\frac{PQ}{n} } , P + Z_{0.05} \sqrt{\frac{PQ}{n} )[/tex]

Answer:

area = 220.5 ft²

Step-by-step explanation:

2(Length) + 2(10.5) = 63 feet

2L + 21 = 63

subtract 21 from each side of the equation:

2L = 42

divide both sides by 2:

L = 21 feet

area = L x W = 21 x 10.5 = 220.5 ft²

Answer:

A = 220.5 ft

Step-by-step explanation:

[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]

[tex]2L + 21 = 63\\[/tex]

[tex]63 - 21[/tex]

[tex]2L = 42[/tex]

Answer:

3/8 divided by 5/6

Step-by-step explanation:

To divide a fraction by a fraction, you multiply the first fraction by the reciprocal (aka the fraction flipped upside down, in this case the reciprocal of 5/6 is 6/5). Since 6/5 is greater than 5/6, 3/8 divided by 5/6 is greater than 3/8 times 5/6.

The value of the function at x = 2 will be 5.

A function is a statement, tenet, or rule that establishes a connection between two variables. Mathematics is replete with functions, which are necessary for the construction of intricate relationships.

The result of the calculation that the mathematical model depicts is the expression's result when the necessary parameters and natural laws are given values.

The table represents a function.

x     f(x)

PLATO USERS

Answer:

10,000

Step-by-step explanation:

Answer:

Correct: A, B, C, E, AND F

Step-by-step explanation:

The reason being, that the larger the negative number, the smaller it gets. Think of it like this:

One person owes another, 8 dollars, and let's say he currently has none. So if he owes 8 dollars and he has none, then it would be 0-8, or, -8.

Now let's say someone else owes 200 dollars, and they have 100 dollars.

If they give 100 dollars, they still need to give another 100, right? so it would be -100 dollars, therefore, a greater debt than the guy with the 8 dollars.

If a negative number looks larger than another, in reality, it's just a bigger debt to pay, so it's smaller worth. -8 is larger than -100 because it's closer to 0.

Last example:

-100, -75, -50, -30, -23, -8, -2, 0, 1, 2, 3... See? -8 is closer to zero than -100, so it's larger.  

C is correct because negatives are smaller than positives. -1 is below 0, so it's smaller than 1, which is greater than 0.

Hope this helps :)

Answer:

$697.09

Step-by-step explanation:

The computation of the investment after 3 years is shown below:

As we know that

Amount = Present value × (1 + rate)^number of years

= $600 × (1 + 0.05 ÷ 365)^365× 3

= $697.09

Hence, the investment after 3 years is $697.09

We simply used the above formula to determine the investment

Step-by-step explanation:

The function that is decreasing on the sale interval as the function graphed in the attached image is " F(x) = -x² + 4x -4.

When the y-value of a function is decreasing as the x-value goes up, that function is said to be a decreasing function.

That is  when x1 < x2 then f(x1) ≥ f(x2)

Let F(x) = 4

Thus

f(4) = -(4)² + 4(4) -4

=  16 + 16 - 4

= 28

Now, let F(x) = 2

Thus

f(2) = -(2)² + 4(2) -4

= 4 + 8 - 4

= 8

Note that X1 = 4 and X2 = 2

Thus  x1 < x2 then f(x1) ≥ f(x2).

Hence Option C is the decreasing function.
