If I have a population of all the apples in an orchard, what would I call the subset of 1000 apples collected from the orchard knowing that the 1000 apples was less than the population of the apples? 50 points ​

Answer:

13.8m

Step-by-step explanation:

angle ATB = 32° - 19° = 13°

In angle OBT:

sin 32° = opposite/hypotenuse = h/BT

h = BT * sin 32

h = 18 * sin 19* sin 32 / sin 13= 13.8 m

So, The height of tree ≈ 13.8 m.

The surface area of the square pyramid is 3920 square feet.

We can use the Pythagorean theorem to find the slant height:

h² = (1/2 * edge length)^2 + height^2

h² = (1/2 * 40)^2 + 21^2

h² = 400 + 441

h² = 841

h = 29

Area of each face = 1/2 * base * height

Area of each face = 1/2 * 40 * 29

Area of each face = 580 square feet

Finally, we can find the surface area of the pyramid by adding up the area of the base and the four triangular faces:

Surface area = Area of base + 4 * Area of each face

Surface area = 1600 + 4 * 580

Surface area = 1600 + 2320

Surface area = 3920 square feet

The cost of each shirt and each pair of pants will be $11 and $12 respectively.

Let

s  = cost of a shirt

p = cost of a pair of pants

From the problem, we know that:

2s + 3p = 58 (Equation 1)

1s + 2p = 35 (Equation 2)

We can solve for s and p by using a method called substitution. We can rearrange Equation 2 to solve for s in terms of p:

s = 35 - 2p

We can then substitute this expression for s into Equation 1 and simplify:

2(35 - 2p) + 3p = 58

Distributing the 2, we get:

70 - 4p + 3p = 58

Combining like terms, we get:

70 - p = 58

Subtracting 70 from both sides, we get:

-p = -12

Dividing both sides by -1, we get:

p = 12

So a pair of pants costs $12.

We can now use this value to solve for the cost of a shirt.

Substituting p = 12 into Equation 2, we get:

s + 2(12) = 35

Simplifying, we get:

s = 11

So a shirt costs $11.

Therefore, each shirt costs $11 and each pair of pants costs $12.

The probability of selecting exactly 2, 3, 4, or 5 inmates who were unemployed when they entered prison is 0.7552.

The coefficient of variation of the number of inmates who were unemployed when they entered prison is 0.5477.

We have,

A)

We can approach this problem using the binomial probability formula since each inmate can either be unemployed or employed when they entered prison, and the probability of being unemployed is 0.4.

The probability of exactly k successes in n trials with probability of success p is given by the binomial probability formula:

P(k) = ( [tex]^nC_k[/tex]) [tex]p^k (1 - p)^{n - k}[/tex]

where [tex]^nC_k[/tex] is the binomial coefficient, which can be calculated as

n! / (k! (n - k)!).

For this problem, we want to find the probability of selecting exactly 2, 3, 4, or 5 inmates who were unemployed when they entered prison:

P(2 or more inmates were unemployed) = P(2) + P(3) + P(4) + P(5)

P(2) = ([tex]^5C_2[/tex])  x 0.4² x 0.6³ = 0.2304

P(3) = ([tex]^5C_3[/tex]) x  0.4³x  0.6² = 0.3456

P(4) = ([tex]^5C_4[/tex]) x [tex]0.4^4[/tex] x 0.6 = 0.1536

P(5) = ([tex]^5C_5[/tex]) x [tex]0.4^5[/tex] * 0.6^0 = 0.0256

Therefore, P(2 or more inmates were unemployed).

= 0.2304 + 0.3456 + 0.1536 + 0.0256

= 0.7552.

The probability of selecting exactly 2, 3, 4, or 5 inmates who were unemployed when they entered prison is 0.7552.

B)

The coefficient of variation (CV) is a measure of relative variability that is defined as the standard deviation divided by the mean.

In this case, we are interested in the number of inmates who were unemployed when they entered prison.

Let X be the number of inmates who were unemployed when they entered prison, and let mu and sigma be the mean and standard deviation of X, respectively.

From the problem statement, we know that the probability of an inmate being unemployed when they entered prison is 0.4, so the expected value of X is:

mu = E(X) = n x p = 5 x 0.4 = 2

To find the standard deviation of X, we can use the formula:

σ = √(np(1 - p))

σ = √(5 x 0.4 x 0.6) = 1.0954

Now,

The coefficient of variation of the number of inmates who were unemployed when they entered prison is:

CV = σ/μ = 1.0954 / 2 = 0.5477

Thus,

The probability of selecting exactly 2, 3, 4, or 5 inmates who were unemployed when they entered prison is 0.7552.

The coefficient of variation of the number of inmates who were unemployed when they entered prison is 0.5477.

Answer:

  3√3 ≈ 5.20 square units

Step-by-step explanation:

You want the area of ∆ABC with centroid G such that ∆ABG is an equilateral triangle with side length 2.

The centroid of a triangle divides the median into two parts in the ratio 1:2, where the shorter part is the distance to the side being bisected, and the longer part is the distance to the vertex.

Here equilateral triangle ABG with side length 2 will have an altitude of √3, so the full length of CH is 3·√3.

The area of ∆ABC is ...

  A = 1/2bh

  A = 1/2(2)(3√3) = 3√3

The area of ∆ABC is 3√3 square units.

__

Additional comments

In the attached figure, GH is the median and altitude of ∆ABG. The figure is symmetrical about the line GH, so ∆ABC is isosceles and CH is its altitude and median.

We can find the length GH different ways. Perhaps the easiest is to refer to memory, where we find the side length ratios in ∆GAH are 1 : √3 : 2. This means for GA=2, GH=√3 and AH=1. We can also use trigonometry, which tells us GH/GA = sin(60°) = √3/2. Then GH=GA·√3/2 = √3.

The  points lies on the line y-2=3(x-4) is (D) (0, -1)

The equation y - 2 = 3(x - 4) represents a line in point-slope form, where the slope of the line is 3 and the y-intercept is -10.

To determine which of the following points lies on this line, we can substitute the x and y coordinates of each point into the equation and see if the equation is true.

Substituting the coordinates of point A into the equation, we get:

5 - 2 = 3(1 - 4)

3 = -9

This equation is not true, so point A does not lie on the line.

Substituting the coordinates of point B into the equation, we get:

-6 - 2 = 3(4 - 4)

-8 = 0

This equation is not true, so point B does not lie on the line.

Substituting the coordinates of point C into the equation, we get:

-8 - 2 = 3(-2 - 4)

-10 = -18

This equation is not true, so point C does not lie on the line.

Substituting the coordinates of point D into the equation, we get:

-1 - 2 = 3(0 - 4)

-3 = -12

This equation is true, so point D lies on the line.

Given that, sin x = √2/2, and cos y = -1/2,

Finding sin y and cos x,

Therefore,

sin y = √3/2

cos x = √2/2

Therefore, tan x = √2/2 / √2/2

tan x = 1

Also,

tan y = -√3/2 / 1/2

tan y = -√3

Now,

1) sin (x+y) = sinx·cosy + cosx·siny

= √2/2×(-1/2) + √2/2×√3/2

= (√6-√2) / 4              

∴ sin (x+y) = (√6-√2) / 4

2) tan(x-y) = tan x - tan y / 1 + tanx tany

= 1 + √3 / 1 - √3 = √3-2

∴ tan(x-y) = √3-2

3) cos(x+y) = cos (x) cos (y) − sin (x) sin (y)

= √2/2 × (-1/2) - √2/2 × √3/2 = -√2/4 - √6/4

= -(√6+√2) / 4    

∴ cos(x+y) = -(√6+√2) / 4    

4) tan(x+y) = tan x + tan y / 1 - tanx tany  

= 1-√3 / 1 +√3 = -2 - √3 = -(2+√3)

∴ tan(x+y) = -(2+√3)

Hence, the correct matches are sin (x+y) = (√6-√2) / 4, tan(x-y) = √3-2, cos(x+y) = -(√6+√2) / 4 and tan(x+y) = -(2+√3)

To create 45 pounds of a third alloy containing 56% aluminum, the metallurgist has to employ around 16.71 pounds of the alloy containing 34% aluminum and roughly 28.29 pounds of the alloy containing 69% aluminum.

Let x be the number of pounds of the alloy containing 34% aluminum that the metallurgist needs to use, and let y be the number of pounds of the alloy containing 69% aluminum.

We can set up a system of two equations to represent the constraints in the problem:

[tex]x + y = 45[/tex]

Since the total amount of alloy produced is 45 pounds

[tex]0.34x + 0.69y = 0.56(45)[/tex]

Since the amount of aluminum in the final alloy is 56% of 45 pounds

Simplifying the second equation, we get:

[tex]0.34x + 0.69y = 25.2[/tex]

Now we have two equations in two unknowns that we can solve using any method of our choice. For this problem, we will use the substitution method.

From the first equation, we can express y in terms of x:

[tex]y = 45 - x[/tex]

Substituting this expression for y into the second equation, we get:

[tex]0.34x + 0.69(45 - x) = 25.2[/tex]

Simplifying and solving for x, we get:

[tex]0.34x + 31.05 - 0.69x = 25.2\\-0.35x = -5.85\\x = 16.71[/tex]

Therefore, the metallurgist needs to use approximately 16.71 pounds of the alloy containing 34% aluminum and approximately 28.29 pounds of the alloy containing 69% aluminum to make 45 pounds of a third alloy containing 56% aluminum.
