A medical clinic is randomly selecting three staff members. there are 7 nurses, 3 doctors, and 4 office. What is the probability that three nurses are selected?
rAnswer:
50%
Step-by-step explanation:
7 nurses
3 doctors
4 offices
14 in total
7/14 or 50% is the probability
The probability that three nurses are selected is 7/14.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
From the information, the total outcome if nurses are randomly selected is expressed as:
Total outcome = 7 + 4 + 3 = 14 outcomes
In order to get the probability that three nurses are selected, the expected outcome is 7;
P = 7/14
Hence the probability that three nurses are selected is 7/14.

If Qs= -20 + 10p, and Qd = 400 - 20p, what is the equilibrium quantity?
The equilibrium quantity is 120 units. The quantity supplied (Qs) equal to the quantity demanded (Qd) and solve for the value of Q.
To find the equilibrium quantity, we need to set the quantity supplied (Qs) equal to the quantity demanded (Qd) and solve for the value of Q.
Given:
Qs = -20 + 10p
Qd = 400 - 20p
Setting Qs equal to Qd:
-20 + 10p = 400 - 20p
Let's solve this equation for p:
10p + 20p = 400 + 20
30p = 420
p = 420/30
p = 14
Now that we have the value of p, we can substitute it back into either the Qs or Qd equation to find the equilibrium quantity.
Using Qd = 400 - 20p:
Qd = 400 - 20(14)
Qd = 400 - 280
Qd = 120
Therefore, the equilibrium quantity is 120 units.

If f(x) = 3x + 10 and g(x) = 2x - 4, find (f- g)(x).
Answer:
(f-g)(x)=x+14
Step-by-step explanation:
Operations with Functions
Given two functions f(x) and g(x), the following operations are defined:
(f+g)(x)=f(x)+g(x)
(f-g)(x)=f(x)-g(x)
(f*g)(x)=f(x)*g(x)
(f/g)(x)=f(x)/g(x)
We have f(x)=3x+10 and g(x)=2x-4. Use the second formula to find
(f-g)(x)=(3x+10)-(2x-4)
Operating:
(f-g)(x)=3x+10-2x+4
Joining like terms:
(f-g)(x)=x+14

The time (t) traveled by Delmar in a car varies inversely as rate (r). If Delmar drives at a speed of 80 mph in 12 hours, what will be the time to travel if he drives at 60 mph? Construct a rational equation that will allow one to determine the answer. Show your work and explain your answer.
When Delmar travels at speed of60 mph, it will take him 16 hours.
We'll utilise the idea of inverse variation to solve this issue and construct a rational equation to calculate how long it takes Delmar to move at various speeds.
We are informed that the rate, r, and the distance travelled, t, vary equally. This can be mathematically represented as
t = k/ r
where k is a variational constant.
Let's use the information provided now. Delmar needs 12 hours to complete the trip when travelling at 80 mph. These values can be used to change the equation.
12 = k/ 80
We can cross-multiply to determine the value of k.
12 * 80 = k
k = 960
Knowing the value of k, we can now:we may apply the equation to calculate how long it takes Delmar to move at 60 miles per hour.
t = 960/60
Simplifying
t = 16
Delmar will arrive in 16 hours if he travels at a speed of 60 mph.
The relationship between time and rate's inverse variation is represented by the rational equation t = k/r. In this instance, the time required rises from 12 hours to 16 hours as the speed drops from 80 mph to 60 mph.
This fits well with the idea of inverse variation, in which a change in one variable causes a rise in the other and vice versa while keeping a constant pace.

Other than itself, which angle is congruent to CBE?
Answer:
<GBF
Step-by-step explanation:
<GBF is congruent to <CBE because they are vertical angles.
The vertical angle theorem states this is true.
Vertical angles are formed by a pair of intersecting lines and are the angles directly across from each other.
Since <GBF and <CBE are vertical angles, they are hence congruent.

Item 6 POSSIBLE POINTS: 8 The length of Chen's office is 15.5 feet and the width is 7.8 feet. Use the formula P = 2ℓ + 2w to find the perimeter of the office. Enter your answer in the box.
Answer:
The perimeter of Chen's office is 46.6 feet.
Step-by-step explanation:
Since the perimeter P = 2l + 2w where l = length of Chen's office and w = width of Chen's office.
Now, since length of Chen's office = l = 15.5 feet and width of Chen's office = w = 7.8 feet, we substitute these values into the equation for the perimeter.
Substituting these values of length and width, we have
P = 2l + 2w
P = 2(15.5) + 2(7.8)
P = 31 + 15.6
P = 46.6 feet
So, the perimeter of Chen's office is 46.6 feet.

3x−8/2 =x−6
im really confused
Answer:
x = -1
Step-by-step explanation:
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get x = -1. :)Answer:
[tex]\boxed {x = -1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3x - \frac{8}{2} = x - 6[/tex]
-Divide [tex]8[/tex] by [tex]4[/tex]:
[tex]3x - \frac{8}{2} = x - 6[/tex]
[tex]3x - 4 = x - 6[/tex]
-Take [tex]x[/tex] and subtract it from [tex]3x[/tex]:
[tex]3x - 4 - x = x - x - 6[/tex]
[tex]2x - 4 = -6[/tex]
-Add [tex]4[/tex] to both sides:
[tex]2x - 4 + 4 = -6 + 4[/tex]
[tex]2x = -2[/tex]
-Divide both sides by [tex]2[/tex]:
[tex]\frac{2x}{2} = \frac{-2}{2}[/tex]
[tex]\boxed {x = -1}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-1[/tex].
Let y = f(x), where 'x9 - * = (xy Find the differential of the
function. dy = 5x* - 6 X
When we differentiate the function y = f(x) with respect to x, we obtain dy/dx = 10x - 6. The differential of the function is then expressed as dy = (10x - 6)dx.
Let's go through the steps in more detail:
Start with the equation y = f(x).
To find the differential, we differentiate both sides of the equation with respect to x, which gives us dy/dx on the left side and d/dx (5x^2 - 6x) on the right side.
Applying the power rule of differentiation, the derivative of 5x^2 with respect to x is 10x. The derivative of -6x with respect to x is -6.
Combining these derivatives, we get dy/dx = 10x - 6.
The differential of the function is represented as dy = (10x - 6)dx, where dx represents a small change in the x-value and dy represents the corresponding small change in the y-value.
In summary, when we differentiate the function y = f(x) with respect to x, we obtain dy/dx = 10x - 6. The differential of the function is then expressed as dy = (10x - 6)dx.

Salama makes fruit baskets with oranges and bananas.
She uses between 8 and 16 oranges and bananas in a ratio of 3 oranges to 2 bananas.
Answer: 9 oranges: bananas
Step-by-step explanation:
The ratio is 3 oranges: 2 bananas. They add up to 5 fruits, so some possible values are 5, 10, 15, 20, 25. We need a value between 8 and 16. This means that we need 15/5 = 3 portions of fruits and since the ratio is 3:2
We multiply this by the original ratio to get 9 oranges: 6 bananas
Answer:
6:4
Step-by-step explanation:
3+2=5, but 5 is not enough so we multiply 3 and 2 to make 6 and 4. Now 6+4= 10 which is between 8 and 16 as we need. So the answer is 6:4
Presto Pizza uses one jar of sauce and one bag of cheese on each large pizza. Each case of sauce has 9 jars. Each case of cheese has 12 bags. What is the fewest number of pizzas they can make if they want to have nothing left over? How many cases of sauce and cheese would they need?
Answer:
36 pizzas
4 cases of sauce and 3 cases of cheese.
Step-by-step explanation:
In order to solve this problem, we need to find the least common multiple of both of these numbers. We do this by simply multiplying these numbers by each factor of 1 until an equal value is an output. Like so...
9*1 = 9 12*1 = 12
9*2 = 18 12*2 = 24
9*3 = 27 12*3 = 36
9*4 = 36
We can now see that the fewest number of pizzas we can make without having anything left over is 36 pizzas. To do this we would need 4 cases of sauce and 3 cases of cheese.

32. 1/3
Step-by-step explanation:
One way to think about a coefficient is this: Set the value of the variable of interest to 1 and evaluate the expression. The value of the expression is the coefficient of the variable of interest.
Here, you're only interested in the variable x, so its coefficient is everything that is not x. The coefficients are ...
27. 3

29. y²
30. 280yz

Sometimes you're asked for the coefficient in a term. In the case of the term 280xyz, the appropriate answer to that question is 280, the constant that multiplies all the variables. When no constant is showing, the coefficient is 1, as in question 31.
