Answer 1

The percent of outpatient surgeries in 1996 is 68.99 % and outpatient surgeries reach is 1992.

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

total surgeries at hospitals is approximated by

f(x)=1314+303 Inx

A) this function predicts for the percent of outpatient surgeries in 1996 IS

x = 1996-1900 = 96.

So f(96) = -1314 + 303 ln(96) =68.99 %

b) f(x) = 60

60 = -1314 + 303 ln(x)

ln x = (1314+60)/303 = 4.53

x = 92.75.

Hence, the percent of outpatient surgeries in 1996 is 68.99 % and outpatient surgeries reach is 1992.

a salesperson receives a weekly salary of 600 , plus a 2.5% commission on sales. her total salary last week was 4720 . what were her sales that week?

Answers

With a total pay last week of $4720 and a 2.5% commission on sales, she made 275 in sales.

What is percent?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.

Here,

The money earned by sales=2.5%*600

=$15

Let the total sales be x,

600+15x=4720

15x=4720-600

15x=4120

x=274.67

x=275 sales

Her last week sales was 275 as her total salary last week was $4720 and she receives 2.5% commission on sales.

The ratio of accessible parking spots to general parking spots 2:75.

Answers

Answer:

Approximately 2.6% of the total number of parking spots are designated as accessible.

Step-by-step explanation:

If the ratio of accessible parking spots to general parking spots is 2:75, this means that for every 2 accessible parking spots, there are 75 general parking spots. This can also be written as a fraction: 2/(2+75) = 2/77.

The fraction represents the proportion of the total number of parking spots that are designated as accessible. In this case, 2/(2+75) = 2/77 = approximately 0.026, or 2.6%. This means that approximately 2.6% of the total number of parking spots are designated as accessible.

It's important to note that the number of accessible parking spots should be determined based on the needs of the community and should meet or exceed the minimum requirements set by law. In the United States, the Americans with Disabilities Act (ADA) sets minimum requirements for the number of accessible parking spaces that must be provided in public parking lots. The exact number of spaces required depends on the size and type of the parking lot.

Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for AJKL.
The orthocenter for AJKL is at point N. What is KN rounded to the nearest tenth?

Answers

The KN is 21.4 rounded to the nearest tenth.

What is an orthocenter?

The orthocenter of a triangle is the place where the perpendicular drawn from the vertices to the opposing sides of the triangle intersect each other. The orthocenter for a triangle with an acute angle is located within the triangle. The orthocenter for a triangle with an acute angle is outside the triangle.

Now we need to find the slope of JL.

From that we have to find the slope of the perpendicular line through B.

Slope of JL=  (y₂ - y₁) / (x₂ - x₁)

J (7, 8) and L (5, 2)

here x₁=  7,y₁  = 8, x₂ = 5 and y₂ = 2

=  -6 / -2

= 3

Slope of the altitude KM  =  -1/ slope of JL = -1/3

Equation of the altitude KM : (y - y₁)  =  m (x -x₁)

Here K(1,2);

(y - 2)  =  -1/3 (x -1)

(y - 2)  =  -x/3 +1/3

Now we need to find the slope of JK.

From that we have to find the slope of the perpendicular line through D.

Slope of KL=  (y₂ - y₁) / (x₂ - x₁)

J(7,8) and K(1,2)

here x₁=  7,y₁  = 8, x₂ = 1 and y₂ = 2

 = 1

Slope of the altitude JO  =  -1/ slope of JL

                                         = -1

Equation of the altitude JO : (y - y₁)  =  m (x -x₁):

 (y - 8)  =  -1 (x - 7)

Solving the equation, x = 21 and y = -6

So the orthocenter N is (21 , -6)

Now the distance of KN is = √(21 - 1)² + (-6 -2)²

                                             =√464

                                             = 21.5

Therefore, the KN is 21.5 rounded to the nearest tenth.

Find AEAE on the rhombus below when AD=4x+2AD=4x+2, DC=7x-13DC=7x−13 and BD=34BD=34.

Answers

The required length of AE will be 14 units on the given rhombus.

We know that all sides of a rhombus are equal, then note that AD equals DC, that is;

4x + 2 = 7x - 13

2 + 13 = 7x - 4x

15 = 3x

Divide both sides of the equation by 3

5 = x

If AD = 4x + 2, then when x  = 5

AD = 4(5) + 2

AD = 20 + 2

AD = 22

So, triangle ADE may now be separated, with AD measuring 22 units and ED measuring 17 units (midpoint between points B and D). Line AE may be determined using Pythagoras' theorem, which states:

AC² = AB² + BC²

Where AC is the hypotenuse, and AB and BC are the two other sides

Substituting for values as given in the question, we now have;

AD² = ED² + AE²

22² = 17² + AE²

484 = 289 + AE²

484 - 289 = AE²

195 = AE²

√195 = AE

13.96 = AE

So, length AE ≈ 14 units (to the nearest whole number)

Thus, the required length of AE will be 14 units on the given rhombus.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is

y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

The standard deviation of a binomial distribution is C. 3.46

What is standard deviation?

Standard deviation is the measure of spread of a set of data.

Since a binomial trial has a probability of success of 0.2, and 75 trials are performed. To find the standard deviation, we use the formula for standard deviation of a binomial distribution.

What is the standard deviation of a binomial distribution?

The standard deviation of a binomial distribution is given by σ = √(npq) where

n = number of possible outcomes, p = probability of successes and q = probability of failures = 1 - p

Given that for our binomial trial

n = 75p = 0.2 andq = 1 - p = 1 - 0.2 = 0.8

So, substituting the values of the variables into the equation, we have that

σ = √(npq)

σ = √(75 × 0.2 × 0.8)

σ = √(75 × 0.16)

σ = √12

σ = 3.464

σ ≅ 3.46

So, the standard deviation is C. 3.46

The international avoirdupois pound, which is legally defined as exactly 0.45359237 kilograms and is divided into 16 avoirdupois ounces, is the definition that is currently most frequently used.

The avoirdupois pound is represented by the worldwide standard symbol, lbm (for the majority of pound definitions), (mostly in the U.S.),  and  (particularly for the apothecaries' pound).

The currency came from the Roman libra (hence the abbreviation "lb"). The Dutch term pond, the Swedish word pund, and the German word pfund are all cognates of the English word pound.
