Answer:

45.

Step-by-step explanation:

Since Hideki is draining a 45 gallon aquarium at a rate of 15 gallons per minute, to determine what is the initial value of the linear function that represents the situation, the following calculation must be performed:

45 (starting number) - 15(number of gallons per minute) X(minutes) = Y

Therefore, the equation would be 45 - 15X = Y, with which the initial value of the linear function that represents the situation is 45.

Answer:

$125 is the sale price.

Step-by-step explanation:

Answer:

24.24% off

Price of tool set: $125

Step-by-step explanation:

$40 is the price change

You can divide 40 by the original price which is 165 and then multiply by 100 to get your percentage change.

40 / 165 = 0.2424

0.2424 * 100 = 24.24

So there is 24.24% discount.

Answer: a. 1.981 < μ < 2.18

              b. Yes.

Step-by-step explanation:

A. For this sample, we will use t-distribution because we're estimating the standard deviation, i.e., we are calculating the standard deviation, and the sample is small, n = 12.

First, we calculate mean of the sample:

[tex]\overline{x}=\frac{\Sigma x}{n}[/tex]

[tex]\overline{x}=\frac{2.31=2.09+...+1.97+2.02}{12}[/tex]

[tex]\overline{x}=[/tex] 2.08

Now, we estimate standard deviation:

[tex]s=\sqrt{\frac{\Sigma (x-\overline{x})^{2}}{n-1} }[/tex]

[tex]s=\sqrt{\frac{(2.31-2.08)^{2}+...+(2.02-2.08)^{2}}{11} }[/tex]

s = 0.1564

For t-score, we need to determine degree of freedom and [tex]\frac{\alpha}{2}[/tex]:

df = 12 - 1

df = 11

[tex]\alpha[/tex] = 1 - 0.95

α = 0.05

[tex]\frac{\alpha}{2}=[/tex] 0.025

Then, t-score is

[tex]t_{11,0.025}[/tex] = 2.201

The interval will be

[tex]\overline{x}[/tex] ± [tex]t.\frac{s}{\sqrt{n} }[/tex]

2.08 ± [tex]2.201\frac{0.1564}{\sqrt{12} }[/tex]

2.08 ± 0.099

The 95% two-sided CI on the mean is 1.981 < μ < 2.18.

B. We are 95% confident that the true population mean for this clinic is between 1.981 and 2.18. Since the mean number performed by all clinics has been 1.95, and this mean is less than the interval, there is evidence that this particular clinic performs more scans than the overall system average.

Answer:

The smaller number is 8

The bigger number is 11

Step-by-step explanation:

let the first number be A

let the second number be B

A + 2B = 30..... equation 1

A + B = 19...... equation 2

Subtract equation 2 from 1.

A + 2B = 30

- A + B = 19

-------------------

0 + B = 11

B = 11

Substitute B = 11 into equation 2

A + B = 19

A + 11 = 19

collect like terms

A = 19-11

A = 8.

A= 8 and B = 11

Answer:

diagonal = = 12.8 inches (to the nearest tenth of an inch)

Step-by-step explanation:

As shown in the diagram attached to this solution:

Let the Length of the rectangular board = a

Let the width = b

Let the diagonal = d

where:

a = 10 inches

b = 8 inches

d = ?

Triangle ABC in the diagram is a right-angled triangle, therefore, applying Pythagoras theorem:

(hypotenuse)² = (Adjacent)² + (Opposite)²

d² = 10² + 8²

d² = 100 + 64

d² = 164

∴ d = √(164)

d = 12.806 inches

d = 12.8 inches (to the nearest tenth of an inch)

N:B Rounding off to the nearest tenth of an inch is the same as rounding off to 1 decimal place.

The polygon being described is a trapezoid, where one base is twice the length of the other base.

A quadrilateral is a four-sided polygon, having four edges and four corners

The polygon being described is a trapezoid, where one base is twice the length of the other base.

Let the shorter base be b and the longer base be 2b.

To divide the figure into two identical trapezoids, the line must pass through the midpoint of the longer base, creating two trapezoids that are mirror images of each other.

The perimeter of each trapezoid can be found as follows:

Perimeter = sum of lengths of all sides

Hence, the polygon being described is a trapezoid, where one base is twice the length of the other base.

Answer:

24

Step-by-step explanation:

Let x = the 10's digit

Let y = the units

then

10x+y = "a number"

:

A number is 4 times the sum of its digits.

10x + y = 4(x + y)

10x + y = 4x + 4y

10x - 4x = 4y - y

6x = 3y

Simply, divide by 3

2x = y

;

The units digit is two more than the tens digit.

y = x + 2

Replace y with 2x

2x = x + 2

2x - x = 2

x = 2

then

y = 4

:

24 is the number

The two digit number is equivalent to 24.

Given is that a number is 4 times the sum of its digits. The units digit is two more than the tens digit.

Let the number be {A}. Then, we can write -

A = 10x + y                             ......... (1)

also

A = 4(x + y)                            ........... (2)

The units digit is two more than the tens digit, so we can write -

y = x + 2                               .............. (3)

So, we can write -

10x + y = 4(x + y)

10x + (x + 2) = 4(x + x + 2)

11x + 2 = 8x + 8

3x = 6

x = 2

So, we can write {y} as -

y = 4

Number will be -

10 x 2 + 4

n = 24

Therefore, the number will be equivalent to 24.

Answer:

x ≠ 5

Step-by-step explanation:

Assuming you mean f(x) = (1/(2x-10))+3

Please be careful with how ambigiuous your question can appear with the / sign.

The domain is the set of values that can be used as an input.

In this case the only input we have that could cause problem is if the denominator of the fraction is 0, because then we divide by 0 which is not allowed.

This gives us 2x-10 ≠ 0

2x ≠ 10

x ≠ 5

The domain of the function is given by the inequality ( 1/2 )x - 10 ≥ 0 and the value of x ≥ 20

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = [ √ ( 1/2 )x - 10 ] + 3

Now , the expression (1/2)x - 10 inside the square root must be greater than or equal to 0, as the square root of a negative number is not defined in the real number system.

(1/2)x - 10 ≥ 0

To solve this inequality, we can isolate x:

(1/2)x ≥ 10

x ≥ 20

Hence , the domain of the function f(x) is x ≥ 20.
