The probability of selecting 3 female employees and 7 male employees to win a promotional trip a company with 10 female and 50 male employees would best be modeled with the _______.
Answer:
The best model is hypergeometric distribution.
Step-by-step explanation:
The probability would be best modeled with hypergeometric distribution.
Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.
The hypergeometric distribution differs from the binomial distribution in the lack of replacements.
Thus, the best model is hypergeometric distribution.
What is the area of a rectangle that is 11ft by 2ft?
Answer: 22 ft²
Step-by-step explanation:
To find the area of a rectangle, we multiply the length and width. It doesn't matter which is which as we get the same answer in the end.
Given information:
Length = 11 ft
Width = 2 ft
Area = length x width
Area = 11 ft x 2 ft = 22 ft²
You'll notice the unit is feet squared or ft², because feet x feet gives us feet².

Find the orthocenter for the triangle described by each set of vertices.
K (3.-3), L (2,1), M (4,-3)
Plzz help ASAP!!!
I'll give brainliest if ur correct
Answer:
The orthocentre of the given vertices ( 2 , -3.5)
Step-by-step explanation:
Step(i):-
The orthocentre is the intersecting point for all the altitudes of the triangle.
The point where the altitudes of a triangle meet is known as the orthocentre.
Given Points are K (3.-3), L (2,1), M (4,-3)
The Altitudes are perpendicular line from one side of the triangle to the opposite vertex
The altitudes are MN , KO , LP
step(ii):-
Slope of the line
[tex]KL = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{1-(-3)}{2-3} = -4[/tex]
The slope of MN =
The perpendicular slope of KL
= [tex]\frac{-1}{m} = \frac{-1}{-4} = \frac{1}{4}[/tex]
The equation of the altitude
[tex]y - y_{1} = m( x-x_{1} )[/tex]
[tex]y - (-3) = \frac{1}{4} ( x-4 )[/tex]
4y +12 = x -4
x - 4 y -16 = 0 ...(i)
Step(iii):-
Slope of the line
[tex]LM = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{-3-1}{4-2} = -2[/tex]
The slope of KO =
The perpendicular slope of LM
= [tex]\frac{-1}{m} = \frac{-1}{-2} = \frac{1}{2}[/tex]
The equation of the altitude
[tex]y - y_{1} = m( x-x_{1} )[/tex]
The equation of the line passing through the point K ( 3,-3) and slope
m = 1/2
[tex]y - (-3) = \frac{1}{2} ( x-3 )[/tex]
2y +6 = x -3
x - 2y -9 =0 ....(ii)
Solving equation (i) and (ii) , we get
subtracting equation (i) and (ii) , we get
x - 4y -16 -( x-2y-9) =0
- 2y -7 =0
-2y = 7
y = - 3.5
Substitute y = -3.5 in equation x -4y-16=0
x - 4( -3.5) - 16 =0
x +14-16 =0
x -2 =0
x = 2
The orthocentre of the given vertices ( 2 , -3.5)
If the slope is 3 what does it represent using this table
Answer:
The table represents a linear function.
The graph of linear function y = 3x is attached below.
Step-by-step explanation:
Given the table
Number of Hours 1 3 5
Number of Tents 3 9 15
Given that the slope is 3.
Finding the slope between (1, 3) and (3, 9)
Slope = (y₂-y₁) / (x₂-x₁)
= [9-3] / [3-1]
= 6 / 2
= 3
Finding the slope between (3, 9) and (5, 15)
Slope = (y₂-y₁) / (x₂-x₁)
= [15-9] / [5-3]
= 6 / 2
= 3
As the value of slope remains constant i.e. slope = m = 3.
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 3 and the point (1, 3)
[tex]y - 3 = 3 (x-1)[/tex]
[tex]y-3 = 3x-3[/tex]
[tex]y = 3x-3+3[/tex]
[tex]y = 3x[/tex]
Comparing with the slope-intercept form of a linear function of line
y = mx+b where m is the slope and b is the y-intercept
slope = 3 and y-intercept b = 0
Therefore, the table represents a linear function.
The graph of linear function y = 3x is attached below.
51) Write the equation of the line passing through (-2, 5) and perpendicular x + 3y = 15.

If Z is a standard normal variable find the probability. The probability that Z lies between -0.558 and 0.558
Answer:
0.4245
Step-by-step explanation:
The probability that Z lies between -0.558 and 0.558 can be written as;
P(-0.558 < z < 0.558) = P(z < 0.558) - P(z < -0.558)
Using z - distribution table, we have;
P(z < 0.558) = 0.7122
P(z < -0.558) = 0.2877
Thus;
P(z < 0.558) - P(z < -0.558) = 0.7122 - 0.2877 = 0.4245

you have 15 milk chocolate Valentines and 10 dark chocolate Valentine.What is the probability that the first Valentine handed out is milk chocolate and the second is dark chocolate.
Answer:
15/25 cuz 25 is the total and there's 15 milk. 2nd as dark chocolate would then be 10/24 cuz you've already taken one chocolate. Multiply by both would be 3/5 × 5/12 = 1/4. Percentage would then be 1/4 = 0.25 , and multiply that by 100% would then be 25%
Answer:
probability of getting milk chocolate =3/5
while
the probability of getting dark chocolate is 2/5
Step-by-step explanation:
milk chocolate=15
dark chocolate=10
there fore total=25
probability of getting milk chocolate=15/25. =3/5
while
the probability of getting dark chocolate=10/25=2/5

On a typical day, the snow on Pike Mountain melts at a rate modeled by the function
M(t), given by M(t)=π/6sin(πt/12)
A snow maker adds snow at a rate modeled by the function S, given by
S(t)=0.006t^2−0.12t+0.87
Both M and S have units in inches per hour and t is measured in hours for 0≤t≤6. At time t = 0, the mountain has 40 inches of snow.
a. How much snow will melt during the 6 hour period? Indicate units of measure.
b. Write an expression for I(t), the total number of inches of snow at any time t.
c. Find the rate of change of the total amount of snow at time t = 3.
Answer:
a. 2in
b. [tex]l(t)=0.002t^{3}-0.06t^{2}+0.87t+2cos(\frac{\pi}{12}t)+38[/tex]
c. l'(3)=0.1938 in/hr
Step-by-step explanation:
a.
In part a, the problem is asking us to find how much snow will melt during the 6 hour period. In order to do so we need to take the M(t) function and integrate it in the given period of time, so we get:
[tex]\int\limits^6_0 {\frac{\pi}{6}sin(\frac{\pi}{12}t)} \, dt[/tex]
So now we solve:
[tex]\frac{\pi}{6}\int\limits^6_0 {sin(\frac{\pi}{12}t)} \, dt[/tex]
this is a known integral, so we get:
[tex]\frac{\pi}{6}[-\frac{12}{\pi}cos(\frac{\pi}{12}t)]^{6}_{0}[/tex]
we can simplify this so we get:
[tex]-2[cos(\frac{\pi}{12}t)]^{6}_{0}[\tex]
[tex]-2[cos(\frac{\pi}{12}(6))-cos(\frac{\pi}{12}(0))][/tex]
[tex]-2[cos(\frac{\pi}{2})-cos(0)][/tex]
[tex]-2[0-1][/tex]
2 in
b)
For part b they want us to write an expression for l(t), the total number of inches of snow at any time t.
in order to do so we need to find an expression for the rate of change of snow. A snowmaker is adding some snow while another amountn of snow is melting, so this rate of change is found by subtracting the two functions, so we get:
l'(t)=S(t)-M(t)
so:
[tex]l(t)=\int {(0.006t^{2}-0.12t+0.87-\frac{\pi}{6}sin(\frac{\pi}{12}t))} \, dt[/tex]
so we integrate this to get:
[tex]l(t)=\frac{0.006}{3}t^{3}-\frac{0.12}{2}t^{2}+0.87t+2cos(\frac{\pi}{12}t)+C[/tex]
and we can simplify this:
[tex]l(t)=0.002t^{3}-0.006t^{2}+0.87t+2cos(\frac{\pi}{12}t)+C[/tex]
so now we need to find what C is equal to, we can use the fact that l(0)=40in so we get:
[tex]40=0.002(0)^{3}-0.006(0)^{2}+0.87(0)+2cos(\frac{\pi}{12}(0))+C[/tex]
which yields:
40=2+C
so
C=40-2
C=38
So the final function is:
[tex]l(t)=0.002t^{3}-0.06t^{2}+0.87t+2cos(\frac{\pi}{12}t)+38[/tex]
c)
for part c we need to find the rate of change of the total amount of snow at time t=3, so in this case we can use the equation we found previously:
l'(t)=S(t)-M(t)
[tex]l'(t)=(0.006t^{2}-0.12t+0.87-\frac{\pi}{6}sin(\frac{\pi}{12}t))[/tex]
and substitute t=3
[tex]l'(3)=(0.006(3)^{2}-0.12(3)+0.87-\frac{\pi}{6}sin(\frac{\pi}{12}(3)))[/tex]
which yields:
l'(t)=0.1938 in/hr

Answer:
as below
Step-by-step explanation:
because the interior angles add up to 180 degrees.. you can solve this
180= 32 + 64 + x hmm
84 = x
so the last angle is 84° :)
as we know that the sum of three interiors angle = 180
Two angles are given 32 and 64
let the angles be a , b and c
A + B + C = 180
32 + 64 + C = 180
C = 180-96
C = 84
Hence the 3rd angle is 84

Answer:
Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.
Step-by-step explanation:
x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.
< means lesser.
> means more than.
A filled up dot means that the number itself is included in the values of x.
A non-filled up dot means that the number itself is not included in the values of x.
An arrow facing left means lesser than that number.
An arrow facing right means more than that number.
Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

Answer:
B. BD = 67Step-by-step explanation:
ABCD is a square.
BD and AC are diagonals and they have equal length.
We have AC = 7x + 18 and BD = 10x - 3
Since AC = BD, we substitute their values and solve for x:
7x + 18 = 10x - 310x - 7x = 18 + 33x = 21x = 21/3x = 7Then find the length of BD:
BD = 7x + 18 = 7*7 + 18 = 49 + 18 = 67Correct option is B. BD = 67
