The radius of the spherical tank of capacity 750 gallons to the nearest hundredth is 2.88 ft.

How much s a gallon?

In both imperial and US customary units, the gallon is a unit of volume. The imperial gallon (imp gal), which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries, is defined as 4.54609 liters; the US gallon (US gal), which is used in the US and some Latin American and Caribbean countries, is defined as 3.785411784 L[1] (231 cubic inches); and the US dry gallon ("usdrygal"), which is defined as 18 US bushel (exactly 4.40488377086 L).

Given data: 1 gallon ≈ 0.1337 ft³

Then, 750 gallons = 0.1337 x 750 ≈ 100.275 ft³

We know, Volume of sphere,  [tex]V=\frac{4}{3}\pi r^{3}[/tex]

then, r = [tex]\sqrt[3]{\frac{3}{4\pi }V }[/tex]

           = [tex]\sqrt[3]{\frac{3}{4\pi } 100.275}[/tex]

           = [tex]2.88 ft.[/tex]

Now we have to,

→ Find the equivalent expression.

The property we use,

→ Distributive property.

The expression is,

→ 8(12 + 30)

Let's simplify the expression,

(a). The equation of the line L in the form of y = mx + b is y + 2x  = 0.

(b). The equation of the line K that passes through the point (0, -1) and is perpendicular to the line L is y = 2x - 1.

(c). The intersection of the lines and K is located at a location with the coordinates (0,-1).

The equation of a line has the usual form axe + by + c = 0. Here, x and y are the variables, a and b are the coefficients, and c is the constant term. You may also find and see the equation of a line in the slope-intercept form, point-slope form, two-point form, intercept form, and normal form.

The formula of slope is given by m = (y₂-y₁)/(x₂-x₁).

Here, m is the slope of the line.

(x₁, y₁) and (x₂, y₂) are the two points of the line.

Now put the value of x₁, y₁, x₂, y₂  in

m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

m = [tex]\frac{3-1}{-1-1}[/tex]

m = 2/-1

m = -2  

The slope of the line perpendicular is:

mₐ = - 1/m

mₐ = -1/-2

mₐ = 2

(a) The equation (in the form y = mx + b) of the line L.

(y-y₁) = m(x-x₁)

(y-1) = -2(x-1)

y-1 = -2x-1

y = -2x

y + 2x  = 0        

(b) The equation of the line K that passes through the (0, -1) and is perpendicular to the line L.

x = 0 and y = -1

y = mx + b  

y = 2x + b  

-1 = 2×0 + b  

-1 = b

b = -1

Substituting the above in y = mx + b to get:

y = mx + b

y =2x + (-1)

y = 2x - 1

(c) The coordinates of the point at which the lines and K intersect.

y = 2x - 1

y+2x+1=0

(2x-1)+2x+1=0

4x =0    

x = 0, y = -1

The intersection of the lines and K is located at a location with the coordinates (0,-1).

The probability that the numbers on the two chips will differ by more than 2 will be ( 1 / 2 ).

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that an urn contains twenty chips, numbered 1 through 20. Two are drawn simultaneously.

Number of favorable outcomes = ( 4 - 2 ) , ( 3 - 1 ) , ( 6 - 4 ) , ( 10 - 8 ), ( 11 - 9 ), ( 7 - 5 ), ( 14 - 12), ( 15- 13 ) , ( 18 - 16 ), ( 19 - 17 ) = 10

Number of samples = 20

Probability = Number of favorable outcomes / Number of sample

Probability = 10 / 20

Probability = 1 / 2

Therefore, the probability that the numbers on the two chips will differ by more than 2 will be ( 1 / 2 ).

The 95% confidence interval estimate for the mean number of absences for clerical workers during the year is (8.132, 11.268).

It should be noted that the mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

Given a = 0.05, Z(0.025) = 1.96 (from standard normal table).

The 95% confidence interval will be:

xbar +/- Z*s/vn

= 9.7 +/- 1.96*4/✓(25)

Regarding the average rate of change of the function, it is found that:

a) 245 habitants per year between 1998 and 2001.

b) The average rate of change was of -328.5 habitants per year between 2002 and 2004.

c) The rate of population increase was greater between 1998 and 2001.

d) The rate of population decrease was greater between 2002 and 2004.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For item a, we have that:

Hence the rate is:

(1591 - 856)/3 = 245.

The average rate of change was of 245 habitants per year between 1998 and 2001.

For item b, we have that:

Hence the rate is:

(826 - 1483)/2 = -328.5.

The average rate of change was of -328.5 habitants per year between 2002 and 2004.

Hence:

c) The rate of population increase was greater between 1998 and 2001.

Answer:

1/9

Step-by-step explanation:

When the quantities are proportional, you are able to find the constant of proportionality by y/x.  If you take each one of the y's listed and divide it by x, you will get 1/9.

For example 1 2/9 ÷11

1 2/9 is the same at 9/9 + 2/9 or 11/9

[tex]\frac{11}{9}[/tex] ÷ 11 is the same as [tex]\frac{11}{9}[/tex] ÷ [tex]\frac{11}{1}[/tex] To divide with fractions, you multiply by the reciprocal.

[tex]\frac{11}{9}[/tex] x [tex]\frac{1}{11}[/tex] The 11 can cancel out and we are left with [tex]\frac{1}{9}[/tex]

Answer: r = [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

y = rx

finding r (substitute y and x):

5 = r x 45

5/45 = r

r = [tex]\frac{5}{45} = simplify = \frac{1}{9}[/tex]

checking:

rx = y

   [tex]\frac{1}{9}[/tex] x 11 = 1 [tex]\frac{2}{9}[/tex]

[tex]\frac{11}{9}[/tex] = 1 [tex]\frac{2}{9}[/tex]

The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.

We need to find the vertices of the given ellipse.

The major axis of the ellipse cuts the ellipse into two distinct points called the vertices of the ellipse. The line perpendicular to the major axis of the ellipse is the minor axis, and it cuts the ellipse at two distinct points called the covertices of the ellipse. The midpoint of the vertices of the ellipse, or the covertices of an ellipse is the centre of the ellipse. The endpoints of the major axis are the vertices, and the endpoints of the minor axis are the covertices.

Equation of the ellipse = x²/a² + y²/b² = 1

Vertices of Ellipse: (a, 0), (-a, 0)

As we know, the endpoints of the major axis are the vertices.

From the given figure we can see that axis of the ellipse passes through the points (-1, 2) and (-9, 2).

The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.

The equation that can represent the fee for x hours is y = 10 + 5x.

A mathematical equation that represents the relationship of two expressions on either side of the sign.

We have,

Initial fee = $10

Let the constant fee for each hour of work = M

Fee for 5 hours of work = $35

Every mowing job for 5 hours = Initial fee + constant fee for 5 hours
$35 = $10 + M x 5

35 = 10 + 5M

25 = 5M

M = 5

So,

If y represents Anumeha's fee (in dollars) for a single job that took x hours for her to complete.
