Step-by-step explanation:

The percentage of salmon filets served by the restaurant is 12%.

To find out the percentage of salmon filets from the total special served by the restaurant,

we need to use the following formula:

Percentage = (Number of salmon filets / Total specials) x 100

The number of salmon filets served by the restaurant is 3.

The total number of specials served by the restaurant is the sum of the number of salmon filets and the number of steak,

which is 22 + 3 = 25.

Therefore, Percentage of salmon filets = (3 / 25) x 100

In this question, we are asked to find out the percentage of salmon filets from the total specials served by the restaurant.

To do that, we used the formula of percentage and substituted the given values in the formula to get the answer.

To calculate percentage, we divide the number of salmon filets by the total specials and then multiply it by 100 to get the percentage.

Here, we know that the number of salmon filets served by the restaurant is 3 and the total specials served are 22 + 3 = 25.

Substituting these values in the formula, we get the percentage of salmon filets served by the restaurant as follows: Percentage of salmon filets = (3 / 25) x 100

To find the derivative of \(\(f(x) = \frac{3}{1 - 2x}\)\) using first principles, we start with the definition of the derivative:

\(\[f'(x) = \lim_{{h \to 0}} \frac{{f(x + h) - f(x)}}{h}\]\)

Substituting the given function into the definition, we have:

\(\[f'(x) = \lim_{{h \to 0}} \frac{{\frac{3}{{1 - 2(x + h)}} - \frac{3}{{1 - 2x}}}}{h}\]\\\\\f'(x) = \lim_{{h \to 0}} \frac{{\frac{3}{{1 - 2(x + h)}} - \frac{3}{{1 - 2x}}}}{h}\]\)

To simplify the expression, we can combine the fractions:

\(\[f'(x)\) = \(\[f'(x) = \lim_{{h \to 0}} \frac{{3h}}{{h(1 - 2(x + h))(1 - 2x)}}\]\)

Next, we simplify the numerator:

\(\[f'(x) = \lim_{{h \to 0}} \frac{{3h}}{{h(1 - 2(x + h))(1 - 2x)}}\]\)

Canceling out the common factor of \(h\), we have:

\(\[f'(x) = \lim_{{h \to 0}} \frac{{3}}{{(1 - 2(x + h))(1 - 2x)}}\]\)

Taking the limit as \(h\) approaches 0, we get:

\(\[f'(x) = \frac{{3}}{{(1 - 2x)(1 - 2x)}} = \frac{{3}}{{(1 - 2x)^2}}\]\)

Therefore, the derivative of \(\(f(x) = \frac{3}{1 - 2x}\)\) from first principles is \(\(f'(x) = \frac{3}{{(1 - 2x)^2}}\).\)

Step-by-step explanation:

Answer:

(x - 2) or (x + 5)

Step-by-step explanation:

Step 1: Write quadratic

x² + 3x - 10

Step 2: Factor

(x - 2)(x + 5)

Answer:  x2 + 3x – 10= (x+5)⋅(x−2)= -6

so x=-6

Step-by-step explanation:  "x2"   was replaced by   "x^2".

Factoring  x2+3x-10  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +3x  its coefficient is  3 .

The last term, "the constant", is  -10  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -10 = -10  

Step-2 : Find two factors of  -10  whose sum equals the coefficient of the middle term, which is   3 .

     -10    +    1    =    -9  

     -5    +    2    =    -3  

     -2    +    5    =    3

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  5  

                    x2 - 2x + 5x - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-2)

             Add up the last 2 terms, pulling out common factors :

                   5 • (x-2)

Step-5 : Add up the four terms of step 4 :

                   (x+5)  •  (x-2)

            Which is the desired factorization

so (x + 5) • (x - 2)= x=-6

Leo is approximately 13.928 km away from the starting point.

Given that Leo walked 7 km south and then 12 km east, we need to determine the distance from the starting point,

To determine the distance from the starting point, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the distance Leo walked south forms one side of a right triangle, and the distance he walked east forms the other side. The distance from the starting point will be the length of the hypotenuse.

Using the Pythagorean theorem, we can calculate the distance from the starting point as follows:

Distance² = (7 km)² + (12 km)²

Distance² = 49 km² + 144 km²

Distance² = 193 km²

Taking the square root of both sides gives us:

Distance = √(193)

Distance ≈ 13.928 km

Therefore, Leo is approximately 13.928 km away from the starting point.

Step-by-step explanation:

Given equation:

\(2x^2=-128\)

Divide both sides of the equation by 2:

\(\implies \dfrac{2x^2}{2}=\dfrac{-128}{2}\)

\(\implies x^2=-64\)

Square root both sides:

The mean of the number of blue chips in the sample is approximately 2.182 and the standard deviation is approximately 1.123. To find the mean and standard deviation of the number of blue chips in the sample, we can use the definition of expectation.

Let X be the random variable representing the number of blue chips in the sample of four chips.

Mean (μ):

The mean is calculated by taking the expected value of X, which can be determined by multiplying the possible values of X by their corresponding probabilities and summing them up.

μ = E(X) = Σ(x * P(X = x))

In this case, the possible values of X are 0, 1, 2, 3, and 4.

P(X = 0) = C(4, 0) * (5/11)^0 * (6/11)^4

P(X = 1) = C(4, 1) * (5/11)^1 * (6/11)^3

P(X = 2) = C(4, 2) * (5/11)^2 * (6/11)^2

P(X = 3) = C(4, 3) * (5/11)^3 * (6/11)^1

P(X = 4) = C(4, 4) * (5/11)^4 * (6/11)^0

where C(n, r) represents the combination of selecting r items from a set of n items.

Using these probabilities, we can calculate the mean as:

μ = 0 * P(X = 0) + 1 * P(X = 1) + 2 * P(X = 2) + 3 * P(X = 3) + 4 * P(X = 4)

Standard Deviation (σ):

The standard deviation is a measure of the dispersion or variability of the values of X around the mean. It is calculated using the formula:

σ = √(E(X^2) - [E(X)]^2)

where E(X^2) is the expected value of X^2, and [E(X)]^2 is the square of the expected value of X.

E(X^2) = Σ(x^2 * P(X = x))

Using the same probabilities as before, we can calculate E(X^2) as:

E(X^2) = 0^2 * P(X = 0) + 1^2 * P(X = 1) + 2^2 * P(X = 2) + 3^2 * P(X = 3) + 4^2 * P(X = 4)

Finally, we can calculate the standard deviation as:

σ = √(E(X^2) - [E(X)]^2)

To find the mean and standard deviation of the number of blue chips in the sample, we calculate the following:

Mean (μ):

μ = 0 * P(X = 0) + 1 * P(X = 1) + 2 * P(X = 2) + 3 * P(X = 3) + 4 * P(X = 4)

= 0 * (C(4, 0) * (5/11)^0 * (6/11)^4) + 1 * (C(4, 1) * (5/11)^1 * (6/11)^3) + 2 * (C(4, 2) * (5/11)^2 * (6/11)^2) + 3 * (C(4, 3) * (5/11)^3 * (6/11)^1) + 4 * (C(4, 4) * (5/11)^4 * (6/11)^0)

After calculating this expression, we find that the mean (μ) is approximately 2.182.

Standard Deviation (σ):

σ = √(E(X^2) - [E(X)]^2)

E(X^2) = 0^2 * P(X = 0) + 1^2 * P(X = 1) + 2^2 * P(X = 2) + 3^2 * P(X = 3) + 4^2 * P(X = 4)

= 0^2 * (C(4, 0) * (5/11)^0 * (6/11)^4) + 1^2 * (C(4, 1) * (5/11)^1 * (6/11)^3) + 2^2 * (C(4, 2) * (5/11)^2 * (6/11)^2) + 3^2 * (C(4, 3) * (5/11)^3 * (6/11)^1) + 4^2 * (C(4, 4) * (5/11)^4 * (6/11)^0)

After calculating this expression, we find that E(X^2) is approximately 4.138.

Now we can calculate the standard deviation:

σ = √(E(X^2) - [E(X)]^2)

= √(4.138 - (2.182)^2)

After performing the calculations, we find that the standard deviation (σ) is approximately 1.123.

Therefore, the mean of the number of blue chips in the sample is approximately 2.182 and the standard deviation is approximately 1.123.

True.

To find 0.5% of a number, we need to multiply the number by 0.5/100, which can be simplified to 5/100 or 1/20. This is because "percent" means "per hundred", so 0.5% is equivalent to 0.5 per 100 or 0.5/100.

Multiplying the number by 5/100 is the same as multiplying it by 0.5/100, so it will give us the correct result.

For example, if we want to find 0.5% of 200, we can multiply 200 by 5/100 or 0.5/100:

The probability of each component failing must be 0.1 or less for the probability of the system functioning to be 0.99.

The formula for the probability of parallel events is as follows: P(A) + P(B) - P(A) * P(B)

For three parallelly connected events, the formula for the probability that none of the events will fail is as follows: Probability = P(A) * P(B) * P(C)

Therefore, the probability of failure for each of the parallel events = 1 - probability that it will function = 1 - p

Also, as the components are independent, we can say that the probability of the system functioning = the probability of all of the components functioning.

As a result, the following formula is used: P(system functions) = Probability(A) + Probability(B) + Probability(C) - Probability(A) * Probability(B) - Probability(B) * Probability(C) - Probability(A) * Probability(C) + Probability(A) * Probability(B) * Probability(C)

Given that P(system functions) = 0.99, we can write the following:

P(system functions) = 1 - P(At least one component fails)0.99 = 1 - (Probability(A) + Probability(B) + Probability(C) - Probability(A) * Probability(B) - Probability(B) * Probability(C) - Probability(A) * Probability(C) + Probability(A) * Probability(B) * Probability(C))

We substitute 1 - p for each of the probabilities in the formula because it is a parallel circuit with independent components.

We have: P(system functions) = 1 - (1 - p)(1 - p)(1 - p) = 0.99 ⇒ (1 - p)³ = 0.01⇒ 1 - p = ∛0.01⇒ 1 - p = 0.1⇒ p = 0.9

The probability of each component failing must be 0.1 or less for the probability of the system functioning to be 0.99.

The chance that the hospital will run out of sleeping pills on any given day is 0.5000 (or 0.5000 with four decimal places).

To calculate the chance that the hospital will run out of sleeping pills on any given day, we can use the normal distribution and Z-score.

First, let's calculate the Z-score using the formula:

Z = (X - μ) / σ

Where:

X = consumption rate per day (1,155 pills)

μ = average consumption rate per day (1,155 pills)

σ = standard deviation (81 pills)

Z = (1,155 - 1,155) / 81

Z = 0

Now, we need to find the probability associated with this Z-score. However, since the demand for sleeping pills can be considered continuous and not discrete, we need to calculate the area under the curve from negative infinity up to the Z-score. This represents the probability of not running out of sleeping pills.

We discover that the region to the left of a Z-score of 0 is 0.5000 using a basic normal distribution table or statistical software.

To find the probability of running out of sleeping pills, we subtract this probability from 1:

Probability of running out of sleeping pills = 1 - 0.5000

Probability of running out of sleeping pills = 0.5000

Therefore, on any given day, the hospital has a 0.5000 (or 0.5000 with four decimal places) chance of running out of sleeping tablets.

So, the odds against Zahra climbing to the top are 4:1

Let's calculate the total cost of all the items purchased by the computer club:

Cost of 14 portfolios = 14 * $24.59

Cost of 14 binders = 14 * $12.92

Cost of 14 school sweatshirts = 14 * $14.00

Cost of 14 music cases = 14 * $1.25

Cost of 14 phone cases = 14 * $1.99

Cost of 14 mouse pads = 14 * $2.14

Total cost of all items = Cost of 14 portfolios + Cost of 14 binders + Cost of 14 school sweatshirts + Cost of 14 music cases + Cost of 14 phone cases + Cost of 14 mouse pads

Plugging in the given values:

Total cost of all items = (14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14)

Now, the computer club will pay for 40% of the total cost. To calculate this, we can multiply the total cost by 40% (or 0.40):

Club's payment = 0.40 * Total cost of all items

The remaining cost will be divided equally among the 14 members:

Remaining cost per member = (Total cost of all items - Club's payment) / 14

Plugging in the values and calculating:

Club's payment = 0.40 * ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14))

Remaining cost per member = ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14) - Club's payment) / 14
