Approximately 1.02lb of arabica coffee should be mixed with 5lb of robusta coffee to make a coffee blend that costs $12.00 per pound.

Let x lb be the amount of arabica coffee that should be mixed with 5lb robusta.

Thus, total cost of Arabica coffee= $28*x

and since cost of robusta coffee per pound is $8.75, thus cost for 5lb= $8.75*5= $43.75

also, total amount of coffee for coffee blend = x+5

thus, total cost for coffee blend= $12(x+5)

Since, Arabica+ Robusta= Mixture

   ⇒ $28*x + $43.75 = $12(x+5)

   ⇒ $28*x + $43.75 = $12x + $60

   ⇒ $28*x - $12x = $60 - $43.75

   ⇒$16x = $ 16.25

   ⇒ x = 1.0156 ≈ 1.02lb

hence, 1.02 pounds of arabica coffee should you mix with 5 pounds of robusta coffee to make a coffee blend that costs $12.00 per pound

The question is incomplete, complete question is as follows:

Arabica coffee costs $28 per pound and Robusta coffee costs $8.75 per pound. How many pounds of Arabica coffee should you mix with 5 pounds of Robusta coffee to make a coffee blend that costs $12.00 per pound?

5. The two triangles are similar. The value of x = 12.

6. The information cannot be used to show that the triangles are similar triangles.

Two triangles are similar to each other if they have the same shape but different sizes, in order words, they must have the same corresponding angle measures but different corresponding side lengths that are proportional to each other.

5. In the first figure, we see that there are two pairs of corresponding congruent angles (a pair of right angles and a pair of vertical angles in both triangles), but different corresponding side lengths.

Therefore, based on the AA similarity theorem that says two triangles are similar of they have two pairs of congruent sides, we can prove that both triangles are similar to each other.

Therefore:

x/9 = 20/15

15x = (9)(20)

15x = 180

15x/15 = 180/15

x = 12

Answer:

(a) The probability that a selected component of this type will last more than 4 years is 0.69.

(b) The probability that a two-year-old component of this type will last an additional 4 years is 0.57.

(c) The 25th percentile of the lifetimes of such components is 3.38 years.
Explanation:

(a) The Gamma distribution has the following probability density function:
f(x) = (λ^α/Γ(α))x^(α-1)e^(-λx)
Where α is the shape parameter, λ is the rate parameter, and Γ(α) is the Gamma function. The mean and variance of the Gamma distribution are:
Mean = α/λ
Variance = α/λ^2
Given that the mean is 5 years and the variance is 25 years^2, we can solve for α and λ:
5 = α/λ
25 = α/λ^2
Solving for α and λ gives us α = 5 and λ = 1. So the probability density function is:
f(x) = (1^5/Γ(5))x^(5-1)e^(-1x)
The probability that a selected component will last more than 4 years is the integral of the probability density function from 4 to infinity:
P(X > 4) = ∫_4^∞ f(x) dx = 0.69

(b) The probability that a two-year-old component will last an additional 4 years is the conditional probability:
P(X > 6 | X > 2) = P(X > 6 and X > 2)/P(X > 2) = P(X > 6)/P(X > 2) = 0.57

(c) The 25th percentile of the lifetimes of such components is the value of x such that the cumulative distribution function is 0.25:
F(x) = 0.25
∫_0^x f(x) dx = 0.25
Solving for x gives us x = 3.38 years.

The 196 kg mass of the coconuts and the 3:5:2 ratio of the mass of the coconuts indicates that we get;

a) There are 96 medium-sized coconuts

b) There are 24 large coconuts

A ratio indicates the quantitative relationship between two quantities, which specifies the number of times a quantity can be obtained from or contains another quantity.

a) The mass of the cococniuts = 192 kg

The specified ratio of the coconuts = 3:5:2

The number of small coconuts = (3/4) × The number of medium sized coconuts

Number of large coconuts = (1/3) × The number of small coconuts

The mass of 3 medium-sized coconuts = 3 kg

The mass of 1 medium-sized coconut = 3 kg/3 = 1 kg

The ratio of the mass of the coconuts indicates that we get;

The mass of the large coconuts = (3/(3+5+2)) × 192 = 57.6 kg

Mass of the medium-sized coconut = (5/(3+5+2)) × 192 kg = 96 kg

The number of medium-sized coconuts = 96 kg/(1 kg/coconut) = 96 coconuts

The number of medium-sized coconuts = 96 coconuts

b) Number of number small coconuts = (3/4) × The number of medium sized coconuts

Therefore; The number of small coconuts = (3/4) × 96 coconuts = 72 coconuts

The population of Smallville increased by 56% from 2000 to 2010.

To calculate the overall percent increase in the population of Smallville from 2000 to 2010, we need to find the combined effect of the individual percent increases from 2000 to 2005 and from 2005 to 2010.

Let's assume the population of Smallville in 2000 was 100 (just for simplicity).

From 2000 to 2005, the population increased by 20%. So the population in 2005 would be 100 + (20% of 100) = 100 + 20 = 120.

From 2005 to 2010, the population increased by 30%. So the population in 2010 would be 120 + (30% of 120) = 120 + 36 = 156.

Now we can calculate the overall percent increase from 2000 to 2010. The percent increase is calculated as the difference between the final and initial values divided by the initial value, multiplied by 100.

Percent Increase = [(156 - 100) / 100] * 100 = 56%

To find the length of the image of the rectangle after dilation, we can use the property of similar triangles. Since the width of the image is known to be 21 in., we can set up a proportion:

(image width) / (original width) = (image length) / (original length)

Substituting the known values, we have:

21 in. / 14 in. = (image length) / 24 in.

The rate at which the volume is changing when the temperature is increasing at 0.05 K/s and the pressure is increasing at 0.02 kPa/s is approximately -0.000480 V liters per second, according to the given equation PV = 8.317.

To find the rate at which the volume is changing when the temperature is 330 K and increasing at a rate of 0.05 K/s, and the pressure is 24 kPa and increasing at a rate of 0.02 kPa/s, we can use the chain rule of differentiation.

Given:

PV = 8.317

Taking the derivative of both sides with respect to time t, we have:

P(dV/dt) + V(dP/dt) = 0

Since we are looking for the rate at which the volume is changing, we need to solve for (dV/dt):

(dV/dt) = -(V(dP/dt))/P

Substituting the given values at the specific time:

P = 24 kPa

(dP/dt) = 0.02 kPa/s

V = PV/8.317 (from the ideal gas equation)

Substituting these values, we have:

(dV/dt) = -((PV/8.317)(dP/dt))/P

(dV/dt) = -((24V/8.317)(0.02))/24

Simplifying:

(dV/dt) = -0.004V/8.317

(dV/dt) ≈ -0.000480 V

Therefore, the rate at which the volume is changing when the temperature is 330 K and increasing at a rate of 0.05 K/s, and the pressure is 24 kPa and increasing at a rate of 0.02 kPa/s, is approximately -0.000480 V liters per second.

The probability that at least one of the shirts you draw will be pink 46/51.

What is probability?

The likelihood of an event happening is determined by probability. There are many instances in real life where we may need to make predictions about how something will turn out combination . The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not. In general, probability has many wonderful uses in games, in business to make forecasts based on likelihood, and in this emerging branch of artificial intelligence. By simply dividing the favourable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. The likelihood of an event occurring might range from 0 to 1.

Here the number of pink shirts=8

Number of green shirts=6

Number of red shirts=4

Here if you draw 2 shirts random then,

P(neither the shirt is blue) = \(\frac{6}{18} *\frac{5}{17}\) = \(\frac{5}{51}\)

Now the at least one of the shirt is pink then,

=> P( at least one shirt is pink)= 1-\(\frac{5}{51}\) = \(\frac{51-5}{51}\) = \(\frac{46}{51}\)

Hence the probability that at least one of the shirts you draw will be pink 46/51.

When the other two angles are 45° and 45° of triangle R, then the parallelogram formed by Copies of triangle R will be square.

Other than these two measures, for example if the other two angles are 30° and 60°, the shape formed will be a parallelogram .

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²
