Answer:

Step-by-step explanation:

Lower limit of range:

H = [tex]\frac{7}{10}[/tex](220-a)

a = 16 [given]

∴ H = [tex]\frac{7}{10}[/tex](220-16)

H = [tex]\frac{7}{10}[/tex](204)

H = [tex]\frac{7}{10}[/tex]×[tex]\frac{204}{1}[/tex]

The water in the rectangular pool which has a depth of 3/4 of the pool's depth has a volume of 2250 cubic feet.

If the depth of the water is 3/4 of the depth of the pool and the depth of the pool is 60 inches, then

depth of the water = 3/4 of the depth of the pool

depth of the water = 3/4(60 inches)

depth of the water = 45 inches = 3.75 feet

Volume is defined as the amount of space any object occupies. The volume for a rectangular prism is given by the formula:

V = lwh

where v is the volume

l is the length

w is the width

h is the height

Since the water occupies the inside of the rectangular pool, to solve the volume of the water, use the formula for the volume of a rectangular prism.

V = lwh

V = 20 feet(30 feet)(3.75 feet)

V = 2250 cubic feet

a) r>0 is the domain of A. b) r = (4/2π + 16)^1/2 - 4

A(r) is a function representing the surface area of a cylinder of height = 8inches and radius = r.

A(r) = 2п[tex]r^{2}[/tex] + 16пr

r must be a positive number, as we can't have a radius of negative length, so the domain of A(r)  is r>0.

Solving for r in terms of A is an odd question, and a little challenging but possible using completing the square:

A/2п = [tex]r^{2}[/tex] + 8r

A/ 2п + 16 = [tex]r^{2}[/tex] + 8r + 16

A/2п + 16 = [tex](r + 4)^{2}[/tex]

r =( A/2п + 16) ^1/2 - 4

Therefore we get to know the range of r i.e., r>0 and radius = (A/2п + 16 )^1/2 - 4

Statement a : "The standard deviation measures the variation of the data. If the standard deviation is 0, then there is some variation, so all the data are different" is false.

Statement b : "All the data must be equal to the mean because the sum of the squares of the differences of the data from the mean is 0. So, all the data take the same value" is true

This is a term in statistics that represent the amount of variation in a data set or simply put the spread of the data set. Standard deviation is solved from the mean of the data, that is we get mean first before solving for standard deviation.

From the definition, if all the data is the same then the data should be equal to the mean. If the data is equal to the mean there will be no spread or variation leading to a zero standard deviation.

Hence we can conclude that statement b is true and statement a is false

The weight of each bag is 23.25 pounds.

For given question,

If all the bags were identical, we need to find the weight of each bag.

Let 'm' be the weight of each bag.

As Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags and all the bags were identical, we get an expression.

8 × m = 187.6

now we solve above expression to find the value of m i.e., to find the weight of each bag.

⇒ 8 × m = 187.6

The volume of water in the sink after x minutes can be represented by a function V(x) = 0.25 x and its domain is 0 ≤ x ≤ 10

After x minutes, the volume of water in the sink will be:

   V = filling rate ⨉ time interval

Information from the problem:

filling rate = 0.25 gallons per minute

time interval = x

Substitute these parameters into the formula:

   V = 0.25 x

The domain of a function is the set of all possible inputs, of which the function is defined.

In this problem, the function is the volume, which is a function of x.

V(x) = 0.25 x

To determine its domain, check the minimum and maximum values of V(x).

When the sink is empty, V = 0.

Then,

V(x) = 0.25 x

  0   = 0.25 x

  x   = 0

When the sink is full, V = 2.5.

Then,

V(x) = 0.25 x

 2.5 = 0.25 x

  x   = 10

Since V(x) has value 0 ≤ V(x) ≤ 2.5, its corresponding input should be  0 ≤ x ≤ 10. This is the domain.

By using the fact that EBC and ABE are supplementary angles, we will see that the measure of angle EBF is 106 degrees.

First, we can notice that angles EBC and ABE are supplementary angles, which means that their measures add up to 180°.

Then we can write:

m∠EBC + m∠ABE = 180°

Replacing what we know we get:

3y + 10 + 2y - 20 = 180°

Now we can solve this linear equation for y, we will get:

5y - 10 = 180

5y = 180 + 10

y = 190/5 = 38

Then we have that:

EBC = 3*38 + 10 = 124°

ABE = 2*38 - 20 = 56°

Now, in the image it says that:

ABE = 2b = 56°

then b = 56°/2 = 28°

And ABF = 7b - 24 = 162°

Then:

EBF = ABF - ABE = 162° - 56° = 106°

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2x + y = -9

3x + 5y = 4

Make y the subject in 2x + y = -9

So, we have

y = -2x - 9

Substitute y = -2x - 9 in 3x + 5y = 4

So, we have

3x + 5(-2x - 9) = 4

Open the bracket

So, we have

3x - 10x - 45 = 4

Evaluate the like terms

-7x = 49

Divide both sides by -7
