Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

Length of the volleyball court in drawing = 2 mm

Step-by-step explanation:

8 meter  = 8 *1000 = 8000 mm

Scale factor = 1 : 8000

Length of the volleyball court in drawing = x

1 : 8000 :: x : 16000

the probability that at least seven customers arrive in three minutes, given that exactly two arrive in the first minute, is approximately 0.081 or 8.1%.

How to solve?

To solve this problem, we can use the Poisson distribution, which models the probability of a certain number of events occurring in a fixed interval of time or space, given the expected rate of occurrence.

Let lambda be the expected rate of customer arrivals per minute. If exactly two customers arrive in the first minute, then the expected number of customers to arrive in three minutes is lambda ×3. We can use this expected value to calculate the probability of at least seven customers arriving in three minutes:

P(X ≥ 7 | X ~ ∝(λ×3))

= 1 - P(X ≤ 6 | X ~ ∝(λ×3))

= 1 - ∑[k=0 to 6] (e²(-λ3) ×(lλ3)²k / k!)

where e is the mathematical constant approximately equal to 2.71828, and k! denotes the factorial of k.

To find lambda, we can use the fact that exactly two customers arrive in the first minute. The Poisson distribution assumes that the number of events in a fixed interval of time or space follows a Poisson distribution with parameter lambda, which represents the expected rate of occurrence. Therefore, lambda is equal to the number of customers arriving per minute, which is 2.

Substituting lambda = 2 into the formula, we get:

P(X ≥ 7 | X ~ ∝(2×3))

= 1 - P(X ≤ 6 | X ~ ∝(6))

= 1 - ∑[k=0 to 6] (e²(-6) ×6²k / k!)

Using a calculator or computer software, we can evaluate this expression to get:

P(X ≥ 7 | X ~ ∝(6)) ≈ 0.081

Therefore, the probability that at least seven customers arrive in three minutes, given that exactly two arrive in the first minute, is approximately 0.081 or 8.1%.

Scenario 2 Magnifi Co. produces a high-end amplifier for musical aficionados. Historically, only 85% of the 200 amplifiers produced per month on average have met the company's demanding standards for quality control. Suppose a random sample of 50 amplifiers is taken from a month's production..

What is the probability that less than 40 of the amplifiers will meet the company's quality standards? b) What is the probability that between 40 and 45 inclusive of the amplifiers will meet the company's quality standards? c) What is the probability that more than 45 of the amplifiers will meet the company's quality standards? a) In order to solve for the probability that less than 40 amplifiers will meet the company's quality standards, we can use the binomial distribution formula: P(X < 40) = Σi=0^39 C(50, i) (0.85)i(1-0.85)50-i

This can be solved using a computer, calculator, or by using a binomial probability table. Using a binomial table, we can find that P(X < 40) = 0.024. Therefore, there is a 0.024 probability that less than 40 amplifiers will meet the company's quality standards. b) To solve for the probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards, we can use the binomial distribution formula again. We need to solve for P(40 ≤ X ≤ 45): P(40 ≤ X ≤ 45) = Σi=40^45 C(50, i) (0.85)i(1-0.85)50-i This can also be solved using a computer, calculator, or binomial table. Using a binomial table, we can find that P(40 ≤ X ≤ 45) = 0.435. Therefore, there is a 0.435 probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards. c) To solve for the probability that more than 45 amplifiers will meet the company's quality standards, we can use the binomial distribution formula one more time. We need to solve for P(X > 45): P(X > 45) = Σi=46^50 C(50, i) (0.85)i(1-0.85)50-i Once again, this can be solved using a computer, calculator, or binomial table. Using a binomial table, we can find that P(X > 45) = 0.056. Therefore, there is a 0.056 probability that more than 45 amplifiers will meet the company's quality standards.Overall, it can be concluded that the probability that less than 40 amplifiers will meet the company's quality standards is low, the probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards is relatively high, and the probability that more than 45 amplifiers will meet the company's quality standards is relatively low.

Answer: Let's call the height of the steeple "h". We can use the tangent function to set up an equation involving the angles of elevation:

tan(40°) = h / x

tan(49° 40') = (h + y) / x

where "x" is the distance from the point to the base of the steeple, and "y" is the height of the point above the ground.

We are given that the distance from the point to the church is 48 feet, so we can use the Pythagorean theorem to find the value of "y":

y^2 = x^2 - 48^2

We can substitute this expression for "y" into the second equation above:

tan(49° 40') = (h + √(x^2 - 48^2)) / x

We can now solve this equation for "h":

h = x tan(49° 40') - x √(1 + tan^2(49° 40')) + 48 tan(40°)

Plugging in the values for the angles and solving for "h", we get:

h ≈ 83.9 feet

Therefore, the height of the steeple is approximately 83.9 feet.

The probability that this batter will hit a home run on this pitcher's next pitch is approximately 0.074, or 7.4%.

To determine the probability that the batter will hit a home run on the pitcher's next pitch,

we need to consider the probabilities of the pitcher throwing a fastball and a curveball, as well as the probabilities of hitting a home run on each type of pitch.

Given that the pitcher throws fastballs 80% of the time and curveballs 20% of the time, we can calculate the probability of the batter facing each type of pitch:

- Probability of facing a fastball = 80% = 0.8
- Probability of facing a curveball = 20% = 0.2

Now, we need to determine the probability of hitting a home run on each type of pitch:

- Probability of hitting a home run on a fastball = 8% = 0.08
- Probability of hitting a home run on a curveball = 5% = 0.05

To find the overall probability of hitting a home run on the pitcher's next pitch, we can use the following formula:

Overall probability = (Probability of facing a fastball * Probability of hitting a home run on a fastball) + (Probability of facing a curveball * Probability of hitting a home run on a curveball)

Plugging in the values we have:

Overall probability = (0.8 * 0.08) + (0.2 * 0.05)
Overall probability = 0.064 + 0.01
Overall probability = 0.074

Therefore, the probability that this batter will hit a home run on this pitcher's next pitch is approximately 0.074, or 7.4%.

Step-by-step explanation:

Given the 2 equations

y = 4x + 5 → (1)

y = x - 4 → (2)

Substitute y = 4x + 5 into (2)

4x + 5 = x - 4 ( subtract x from both sides )

3x + 5 = - 4 ( subtract 5 from both sides )

3x = - 9 ( divide both sides by 3 )

x = - 3

Substitute x = - 3 into either of the 2 equations and evaluate for y

Substituting into (2)

y = x - 4 = - 3 - 4 = - 7

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

The general solution to the given second-order linear homogeneous differential equation is y(x) = c1e^(3x) + c2e^(-2x), where c1 and c2 are arbitrary constants.

To find the general solution, we first consider the corresponding homogeneous equation, which is obtained by setting the right-hand side of the given equation to zero:

y′′ − y′ − 6y = 0

The characteristic equation associated with this homogeneous equation is:

r^2 - r - 6 = 0

Solving this quadratic equation, we find two distinct roots: r1 = 3 and r2 = -2. Therefore, the general solution to the homogeneous equation is:

y_h(x) = c1e^(3x) + c2e^(-2x)

Next, we need to find a particular solution to the given non-homogeneous equation. The particular solution takes the form of a polynomial multiplied by the known term on the right-hand side, in this case, 6x^3. Since the degree of the polynomial is 3, we try a particular solution of the form y_p(x) = ax^3 + bx^2 + cx + d.

Substituting this into the non-homogeneous equation, we obtain:

y_p′′ − y_p′ − 6y_p = 6x^3

Simplifying and collecting terms, we can equate coefficients of like powers of x on both sides. After solving the resulting system of equations, we find a particular solution:

y_p(x) = x^3/3

The general solution to the non-homogeneous equation is the sum of the homogeneous and particular solutions:

y(x) = y_h(x) + y_p(x)

     = c1e^(3x) + c2e^(-2x) + x^3/3

This is the general solution to the given differential equation. The arbitrary constants c1 and c2 can be determined by applying initial or boundary conditions if provided.

Answer:

2.5 * 10^-5 cm

Step-by-step explanation:

Scientists know that the diameter of a normal cell is 0.000025 cm. How is that number written in scientific notation?​ please help

Given that:

Diameter of a Normal cell = 0.000025 cm

In standard form:

Count the spaces in between each digit from right to left until the point where the decimal point is located.

The number of spaces in between each digit = 6

Since the spaces are counted backwards, the power notation takes a negative (-) sign.

0.000025 is thus rewritten as :

0.000025 = 25 * 10^-6

To place a decimal point in between 25 and rewrite as 2.5,

We the write as :

2.5 * 10^-5 cm
