5% of what number is 25

Answer:

Fraction it's 21/25      Decimal it's 0.84        Percent is 84%

Step-by-step explanation:

Answer: its a half a percent or 50%

Step-by-step explanation:

Answer:

50%

Step-by-step explanation:

First, to find a percentage, you divide the part out of the whole (numerator out of the denominator in a fraction);

4 ÷ 8 = 0.5

Once you have your decimal number, you need to move the decimal point 2 spaces to the left to turn it into a percentage;

0.5 = 50

Therefore, the percent decrease is 50%.

The terms minimum and infimum are both related to the concept of lower bounds in mathematics. A minimum is the smallest value in a set of numbers, whereas an infimum is the greatest lower bound of a set.

A minimum is a value that is less than or equal to all other values in the set, while an infimum is a value that is less than or equal to all other values in the set, but not necessarily the smallest value.

For example, if we consider the set {2, 4, 6}, the minimum is 2 and the infimum is also 2. However, if we consider the set {2, 4, 6, 8}, the minimum is 2 and the infimum is 4. In the latter set, 4 is the greatest lower bound, meaning that all other values in the set are greater than or equal to 4.

The probability of striking the bull's-eye all three times when throwing the dart three times is 1/216.

The probability of striking the bull's-eye on each throw is 1/6. Since each throw is an independent event, we can multiply the probabilities to find the probability of striking the bull's-eye all three times.

Let's denote the event of striking the bull's-eye as "B" and the event of not striking the bull's-eye as "N". The probability of striking the bull's-eye is P(B) = 1/6, and the probability of not striking the bull's-eye is P(N) = 1 - P(B) = 1 - 1/6 = 5/6.

Since each throw is independent, the probability of striking the bull's-eye on all three throws is:

P(BBB) = P(B) * P(B) * P(B) = (1/6) * (1/6) * (1/6) = 1/216

Therefore, the probability of striking the bull's-eye all three times is 1/216.

The parachutist started the free fall at a height of 68.12 meters above the ground.(b) The height at which the fall begins is 68.12 meters. The units of height are meters.

Given parameters: Initial velocity (u) = 0 m/s

           Final velocity (v) = 2.8 m/s

           Initial height (h) = ?

           Final height (s) = 65 m

Acceleration (a) = 2.4 m/s²Time taken (t) = ?

The formula for calculating the time taken in a free fall with an initial velocity is given by;

                                   v = u + at

Wherev = final velocityu = initial velocity

                       a = accelerationt = time taken

Rearranging the formula to get the time taken;

                       => t = (v - u) / a=> t = (2.8 - 0) / 2.4=> t = 1.17 seconds

(a) The parachutist is in the air for 1.17 seconds.

Since the parachutist starts from rest at a height (h) above the ground, her final velocity can be calculated using the formula;

                                 v² = u² + 2asWherev = final velocityu = initial velocitya = acceleration due to gravitys = height fallen

Rearranging the formula to get the initial height (h)

                                          ;=> h = s - u² / 2a

                                            => h = 65 - 0² / 2(2.4)

                                            => h = 68.12 meters (approx)

Therefore, the parachutist started the free fall at a height of 68.12 meters above the ground.(b) The height at which the fall begins is 68.12 meters. The units of height are meters.

Therefore, the answer in (a) is 1.17 seconds (s), while the answer in (b) is 68.12 meters (m).

(2)(9) + 75 = 75+18

Step-by-step explanation:

(2)(9) + 75 = 75+18

The expression written as a product of a number and another sum is 3(25 + 8)

Given the expression 75 + 18, we are to write as a product of a number and another sum.

First we need to find the GCF of 75 and 18

75 = 3 * 25

18 = 3 * 6

Since 3 is common to both D+GCF, we can factor it out from the expression to have:

75 + 18 = 3(25 + 8)

Hence the expression written as a product of a number and another sum is 3(25 + 8)

The value of x  for The quadrilateral which is a trapezoid is if the top is 21 and the bottom is 27 is option 2 that is 5.

Quadrilaterals called trapezoids have two parallel and two non-parallel sides. It also goes by the name Trapezium. A trapezoid is a closed, four-sided form or figure that has a perimeter and covers a specific area. It is a 2D figure rather than a 3D one. The bases of the trapezoid are the sides that are parallel to one another. Legs or lateral sides refer to the non-parallel sides. The height is the separation between the parallel sides.

From the given diagram, the expression below is true:

2(5x - 1) = 21 + 27

Expand

10x - 2 = 48

10x = 48 + 2

The weight of a small Starbucks coffee that is heavier than 480 grams corresponds to a probability of 0.0062.

To find the weight that corresponds to each event, we'll need to use the normal distribution formula:

Z = (X - μ) / σ where Z is the standard score (or z-score), X is the observed value, μ is the mean, and σ is the standard deviation.

We can use this formula to convert the weight of a small Starbucks coffee into a z-score, and then use a standard normal distribution table (such as Appendix C) to find the corresponding probability (or vice versa).

Here are the specific events and their corresponding weights:

1. The weight of a small Starbucks coffee that is lighter than 400 grams. First, we need to convert the weight of 400 grams into a z-score:

Z = (400 - 420) / 24 = -0.83 Using Appendix C or Excel.

we can find that the probability of a z-score being less than -0.83 is 0.2033.

Therefore, the weight of a small Starbucks coffee that is lighter than 400 grams corresponds to a probability of 0.2033.

2. The weight of a small Starbucks coffee that is between 420 and 450 grams. To find the z-scores corresponding to these weights, we need to use the formula twice: For 420 grams: Z = (420 - 420) / 24 = 0 For 450 grams: Z = (450 - 420) / 24 = 1.25 Using Appendix C or Excel, we can find that the probability of a z-score being between 0 and 1.25 is 0.3944.

Therefore, the weight of a small Starbucks coffee that is between 420 and 450 grams corresponds to a probability of 0.3944.

3. The weight of a small Starbucks coffee that is heavier than 480 grams. Again, we need to convert the weight of 480 grams into a z-score:

Z = (480 - 420) / 24 = 2.50 Using Appendix C or Excel, we can find that the probability of a z-score being greater than 2.50 is 0.0062.

Therefore, the weight of a small Starbucks coffee that is heavier than 480 grams corresponds to a probability of 0.0062.

Step-by-step explanation:

We are given the following function:

\(f(x) = -7 - 2√x\) We are required to find the values of A, B and C in the expression:

\(f(x + h) - f(x)/h\) in the form \(A/√(Bx + Ch) + √x\) First, let's calculate f(x + h) and f(x):

\(f(x) = -7 - 2√xf(x + h)\)

\(= -7 - 2√(x + h)\)  Now, let's substitute these values in the expression:

\(f(x + h) - f(x)/h = [-7 - 2√(x + h)] - [-7 - 2√x]/h\)

\(= [-2(√(x + h)) + 2√x]/h\)

\(= 2(√x - √(x + h))/h\)  We can rationalize the denominator by multiplying both numerator and denominator by\((√x + √(x + h)):\)

\((2/[(√x + √(x + h)) * h]) * [(√x - √(x + h)) * (√x + √(x + h))]/[(√x - √(x + h)) * (√x + √(x + h))]\)This simplifies to:

\((2(√x - √(x + h))/h) * (√x + √(x + h))/[(√x + √(x + h))]\)

\(= [2(√x - √(x + h))/h] * [√x + √(x + h)]/[(√x + √(x + h))]\)

\(= 2(√x - √(x + h))/[(√x + √(x + h))]\) The expression can be written in the form\(A/√(Bx + Ch) + √x\)

The new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.

(a) The values of E(θ^1) and E(θ^2) are unknown without further information. Being unbiased estimators means that, on average, they provide estimates that are equal to the true population parameter θ. Therefore, we have:

E(θ^1) = θ

E(θ^2) = θ

(b) To find the expectation E(θ^3), we can use the linearity property of expectations:

E(θ^3) = E(aθ^1 + (1 - a)θ^2)

Since θ^1 and θ^2 are unbiased estimators, their expectations are equal to θ:

E(θ^3) = E(aθ^1 + (1 - a)θ^2) = aE(θ^1) + (1 - a)E(θ^2)

Using the values from part (a), we have:

E(θ^3) = aθ + (1 - a)θ = θ(a + 1 - a) = θ

Therefore, the new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.

Answer:

∠x = 60°

Step-by-step explanation:

first:

∠a = 60° was given

the sides on each side of ∠a are equal so their opposite angles are equal also.

The sum of the interior angles of any triangle is 180°

The angles opposite ∠a are (180° - 60°)/2 = 60° each

Second:

∠b = 60° was given

so the angles opposite ∠b are also 60° each

Third:

the 2 angles opposite x are both 60° each because they are both vertical angles to 60°

That leaves ∠x  to be 180° - 60° - 60° = 60°
