karrie was late to work 14 times last year. if she workded 250 days last year, what percent of the days was she left

Answers

By using the concept of percentage, it can be calculated that Karrie was late to work in 5.6 % of the days.

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

For example 9% means [tex]\frac{9}{100}[/tex]. Here 9 is expressed as a fraction of 100

Here the concept of percentage will be used

Number of days in which Karrie was late = 14

Total number of days she worked = 250

Percentage of days Karrie was late = [tex]\frac{14}{250} \times 100[/tex] = 5.6 %

the product of two positive integers is 18. the positive difference of these two integers is 3. what is the sum of the two integers?

Answers

The sum of the given two positive integers is 9.

According to the question,

We have the following information:

The product of two positive integers is 18. the positive difference of these two integers is 3.

Now, let's take the first positive integer (larger one) to be x and the second positive integer to be y.

xy = 18 ...(1)

x-y = 3

x = 3+y

Putting this value in equation 1:

(3+y)y = 18

[tex]y^{2} +3y-18 = 0[/tex]

[tex]y^{2}[/tex]+6y-3y-18 = 0

y(y+6)-3(y+6) = 0

(y+6) (y-3) = 0

y-3 = 0 and y+6 = 0

y = 3 or y = -6

Now, the number is positive so it will be 3.

Putting this value in equation 1:

xy = 18

3x = 18

Dividing by 3 on both sides of the equation:

x= 18/3

x = 6

Sum of integers = 3+6

Sum of integers = 9

Hence, the sum of the given two positive integers is 9.

an office typically orders 60 ink refills at a time. the company estimates that handling costs are 40% of the $10 unit cost and the monthly demand is around 20 units. the assumptions of the basic eoq model are applicable. what would be the cost to order?

Answers

Cost to order as per the economic order quantity model is equal to 10units.

As given in the question,

Demand of units per month = 20 units

Ordering cost  =  $10 unit

Carrying cost = 40% of 10

                       = (40 /100) × 10

                       = $4

Economic order quantity model ( EOQ)

= √[ 2 × ( Demand rate ) × ordering cost ]/ carrying cost

Substitute the value we get,

= √ ( 2 × 20 × 10 )/ 4

= √400 / 4

= √100

= 10 units.

Therefore , as per the economic order quantity (EOQ) model cost to order is for 10 units.

The answer of 74 provided by brey90 is absolutely correct. I am just providing a mathematical way of determining the number

Let the number be ab
That means [tex]b[/tex]  is in the units place and [tex]a[/tex] is in the tens place.

The actual value of this two digit number is  [tex]10a + b[/tex]  

The difference between a and b is 3:
[tex]a - b = 3[/tex]  [1]

If we reverse the number we get the number [tex]ba[/tex]

The actual value of [tex]ba[/tex] is [tex]10b + a[/tex]

The sum of [tex]ab[/tex] and [tex]ba[/tex] is 121. This means the sum of their actual values must be 121

So we get
[tex]10a + b + 10b + a = 121\\\\11a + 11b = 121\\\\[/tex]

Dividing both sides by 11 yields:
[tex]a + b = 11[/tex]  [2]

Add [1] and [2] to get:
[tex]2a = 14\\\\a = 7\\\\[/tex]

Sub for a in Equation [1] to get

Answers

Answer:
6. y = 2·2^x — exponential
7. y = (1/16)·4^x — exponential
8. neither
9. neither
Step-by-step explanation:
First of all, no table with an entry for 0 will be an inverse relation. When the ratio of one term to the next is a constant, the function is exponential. When the difference from one term to the next is a constant, the function is linear.
Here, some tricks are thrown in. The first two (6 and 7) are exponential functions. The common ratios are 2 and 4, respectively. The multiplier is the value of the function when x=0.
6. y = 2·2^x
7. y = (1/16)·4^x
8. The table for function 8 is that of what is known as a harmonic sequence. The denominator increases linearly. It is a kind of an inverse function, but not the kind we normally call an inverse function.
y = 1/(x+1)
9. The function is not obviously linear, inverse, or exponential. The 6 points can always be described by a polynomial of degree n-1, where n is the number of points. The 5th-degree polynomial that fits these points is tedious to find, but can be found to be ...
y = (120 + 103702x - 213975x^2 + 149665x^3 - 42225 x^4 + 4393x^5)/120

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the number of soda bottles the machine can make in 1 minute be = y

Now , the equation is

Let the first point in the graph be A ( x₁ , y₁ )

The value of A ( x₁ , y₁ ) = A ( 3 , 48 )

Let the second point in the graph be B ( x₂ , y₂ )

The value of B ( x₂ , y₂ ) = A ( 7 , 112 )

Now , the slope of the line joining the points can be found out from the equation of slope

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

So , the slope of the point is m = steep of the line or inclination

Slope m = y / x

Substituting the values for x and y , we get

Slope m = 48 / 3

Slope m = 16

Therefore , the equation of line will be y = mx + c

y = 16x

Now , there are 60 seconds in a minute

So , 1 minute = 60 seconds

Substituting the value of x = 60 in the equation , we get

y = 16x

y = 16 x 60

y = 960 bottles

Therefore , the value of y = 960

Hence , The number of soda bottles the machine can make in each minute is 960 bottles

What is standard deviation?

Standard Deviation is a measure that shows what quantity variation (such as unfold, dispersion, spread,) from the mean exists. the quality deviation indicates a “typical” deviation from the mean. it's a well-liked live of variability as a result of it returns to the first units of live of the info set.

Main body:

X - Binomial(n = 130, p = 0.5)

Binomial can be approximated to normal with: μ = np = 130*0.5 = 65

σ = √np(1 − p) - = √130* (0.5)(1 − 0.5)

σ = 5.7

P(55 ≤ X ≤ 69 )

Since we are approximating a discrete binomial distribution by continuous normal distribution, values between 54.5 and 68.5 both approximate to 55. Thus, "between 55 and 69" corresponds to continuous normal distribution with P(54.5 < X 68.5) after continuity correction.

Normal Distribution, x₁ = 54.5, x2 = 68.5, µ = 65, σ = 5.7

We convert this to standard normal using z =

z₁ = 54.5-65/ 5.7 ≈ - 1.84

z₂ = 68.5-65/ 5.7  ≈ 0.614

P(54.5 < X < 68.5) = P(- 1.84 < Z < 0.614)

= P(Z < 0.614) − P(Z <- 1.84)

= 0.7291 - 0.0329   (from z-table)

= 0.6962

Answers

The values of c in the given equation, 19 = | 5c - 4 |, are c = -3 and c = 4 3/5

Solving an equation

From the question, we are to solve the given equation for all values of c

The given equation is

19 = | 5c - 4 |

From this equation, we can write that

19 = (5c - 4) and 19 = -(5c - 4)

Solving the first equation

19 = (5c - 4)

19 = 5c - 4

Add 4 to both sides of the equation

19 + 4 = 5c - 4 + 4

23 = 5c

Divide both sides by 5

23/5 = 5c/5

4 3/5 = c

Therefore,

c = 4 3/5

Solving the second equation

19 = -(5c - 4)

19 = -5c + 4

Subtract 4 from both sides of the equation

19 - 4 = -5c + 4 - 4

15 = -5c

Divide both sides by -5

15/-5 = -5c/-5

-3 = c

a right triangle has a hypotenuse of length 3 units and one side of length 2 units. what is the area of the triangle?

Answers

The area of the triangle is 3 units^2. Since the area is equal to

hside * side/ 2.

Define area.

The measure of a region's size on a plane or curved surface is called area. While surface area refers to the area of an open surface or the boundary of a three-dimensional object, the area of a plane region or plane area refers to the area of a form or planar lamina.

Area is defined as the total amount of space occupied by a flat (2-D) surface or the shape of an object. On a sheet of paper, draw a square with a pencil. It is a two-dimensional figure. The area of a shape on paper is the area it occupies.

Solution Explained:
Given,

Length of Hypotenuse = 3units
One side = 2units

Area = (Length of Hypotenuse X Length one side) / 2
        = (3 X 2) / 2
        = 3units^2 (after calculation)

phenolphthalein has a pka of 9.7 and is colorless in its acid form and pink in its basic form. for ph= 5.3 calculate [in−]/[hin] . for ph= 11.4 calculate [in−]/[hin] .

Answers

Part a:  [In⁻]/[HIn] = 4.0 × 10⁻⁶

Part b: [In⁻]/[HIn] = 50.11, for the given phenolphthalein solution.

Explain the term acid form?Typical aqueous acids include acetic acid, hydrochloric acid, and gastric acid, which activates digestive enzymes. Hydrochloric acid is a solution containing hydrogen chloride.

Using the Henderson-Hasselbalch equation to determine the indicator's pH  is as follows:

pH = pKa + log[In⁻]/[HIn]

In which,

Ka = dissociation constant of acid.

As the stated value-

Part a:

pKa = 9.7

pH = 5.3

Thus,

5.3 = 9.7 + log[In⁻]/[HIn]

log[In⁻]/[HIn]  = - 4.4

[In⁻]/[HIn] = Antilog (-4.4)

[In⁻]/[HIn] = 4.0 × 10⁻⁶

Part b:

pKa = 9.7

pH = 11.4

Thus,

11.4 = 9.7 + log[In⁻]/[HIn]

log[In⁻]/[HIn]  = 1.7

[In⁻]/[HIn] = Antilog (-4.4)

[In⁻]/[HIn] = 50.11
