Answer:

95%

Step by step explanation:

z = 17-21 / 2 and z = 25-21/2

z=-2 (2.28%) z=2 (97.72%)

97.72 - 2.28 = 5.44

100% - 5.44% is about equal to 95%

By using  1-PsiTarget(H15, 500) we compute the probability of cell H15's value exceeding 500 in a spreadsheet simulation.

PsiTarget is a function commonly used in spreadsheet simulation software to calculate probabilities.

The first argument (H15) specifies the cell you want to calculate the probability for.

The second argument (500) represents the target value you want to compare against.

The PsiTarget function returns the probability of the cell's value being less than or equal to the target value.

By subtracting this probability from 1, you get the probability of the cell's value exceeding the target value.

Therefore, the correct formula to compute the probability of cell H15's value exceeding 500 is 1-PsiTarget(H15, 500).

How to apply basic trigonometry?

In order to determine the angles, we would apply basic trigonometry. From the diagram of the right-angled triangle shown below, we can deduce the following parameters:

Angle (θ) = 45°.

Opposite (Opp) side = a.

Hypotenuse (Hyp) = c.

Adjacent (Adj) side = b.

By applying the basic trigonometry functions, we have:

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

Answer:

39 tulips

Step-by-step explanation:

76 - 37 = 39

The total number of tulips that the florist had was 39.

Total number of roses and tulips together = 76

Total number of roses = 37

Therefore, to find the total number of tulips we need to subtract the total number of roses from the total number of flowers together.

Hence, the total number of tulips = 76 - 37 = 39

Thus the total number of tulips that the florist had was 39.

Step-by-step explanation:

Credit: The person who couldn't "[...]answer for some reason"

Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.

Answer:

y is directly proportional to x

y=kx, where k is a constant

Now, y=12 when x=15

\(12 = k \times 15 \\ k = \frac{12}{15} \\ \boxed{k = 0.8}\)

When x=2,

\(y = 0.8 \times 2 \\ \boxed{y = 1.6}\)

Answer:

x=66

Step-by-step explanation:

180-114=66

Interior angles on the same side of transversal are supplementary (180°).

=> x = 180° - 114°

=> x = 66°

The given statement "The this pointer is not automatically passed to static member functions of a class." is false as static member functions can be called without creating an object of the class, and the "this" pointer is used to refer to the current instance of the class. Since no instance is required for static member functions, the "this" pointer is not applicable in this case.

In object-oriented programming, a class is a blueprint for creating objects, and member functions are functions defined within a class that can be called on objects of that class.

Static member functions, also known as class methods, are special member functions that are associated with the class itself rather than any specific object or instance of the class. They are declared using the "static" keyword.

Since static member functions do not operate on specific instances of the class, they do not have access to the "this" pointer. The "this" pointer is a hidden pointer that points to the current object instance, allowing non-static member functions to access the data members and other member functions of the object. However, static member functions do not have this pointer because they are not tied to any specific object.

Static member functions can only access static members of the class, which include static variables and other static member functions. They can be called using the class name itself, without creating an instance of the class. This is because they are not associated with any particular object but rather with the class as a whole.

Answer:

The value of the car at the end of 3 years will be $13707.

Step-by-step explanation:

If the original value of the car is $20000, then after the first year, the value of the car will be $20000 - (12/100)*$20000 = $17600.

After the second year, the value of the car will be $17600 - (12/100)*$17600 = $15552.

After the third year, the value of the car will be $15552 - (12/100)*$15552 = $13707.

Therefore, the value of the car at the end of 3 years will be $13707.

The value of seaweed height that divides the bottom 30%  from the top 70% is 8.96 cm

An indicator of how much a group of numbers vary or are dispersed is the standard deviation. When the standard deviation is low, the values tend to fall within a narrow range of the set's mean, but when it is large, the values tend to deviate from that mean more.

Mean. The population from which the scores were sampled is represented by the mean of the sampling distribution of the mean. As a result, the sampling distribution's mean is also the population's mean if the population as a whole has a mean of.

μ= 10 cm

σ= 2 cm

the value of the variable X at which the distribution's bottom 0.30 and top 0.70 are separated.

P(X≤x)= 0.30

P(X≥x)= 0.70

The Z value that divides the bottom 0.30 from the top 0.70 of the standard normal distribution must be identified. Using the formula

Z=(X-μ)/σ, the Z value must then be converted to the matching X value.

P(Z≤z)= 0.30

Search for the probability of 0.30 in the table's body to get to the margins where the Z value is formed. Since the distribution's mean is "0," negative values can be found in the lower half of the distribution.

z= -0.52

The value of X must now be cleared:

Z= (X-μ)/σ

Z*σ= X-μ

X= (Z*σ)+μ

X= (-0.52*2)+10= 8.96

The triangle is an isosceles.

Subtract the angle 40 from 180 (all angles in a triangle add up to 180

The bottom two angles are the same, so dividing the number given by 180 - 40 by 2

Central tendency, is the term that relates to the way data tend to cluster around some middle or central value.

Measures of central tendency are summary statistics that represent the center point or typical value of a dataset. Examples of these measures include the mean, median, and mode. These statistics indicate where most values in a distribution. Mode in statistics is the number of times a number is repeated. The number which is repeated maximum times in a series of data is known as the modular number. The mode is used to compare data that has extreme figures. Central tendency simply means most scores in a normally distributed set of data tend to cluster near the center of a distribution.

The measure of ∠O is 56°. The solution has been obtained by using properties of circles.

What is a circle?

A circle is a round-shaped figure that has no sides or edges. A circle is a closed shape, a two-dimensional shape, and a curved shape in geometry.

We are given that m∠R = 28°.

Now, we take a point P on the circumference of the circle.

We know that in a circle, the angles that the same arc subtends on the circumference have equal measurements.

So, both the angles i.e. ∠P and ∠R are same as they are subtended by the same arc.

Therefore, we get

m∠P = m∠R = 28°

Moreover, an arc's angle at the circle's centre is twice as large as its angle at the circle's edge.

So, from this we get

⇒ m∠O = 2 * m∠P

⇒ m∠O = 2 * 28°

⇒ m∠O = 56°

Hence, the measure of ∠O is 56°.

There are 125 four-digit even numbers that can be formed using the digits 2, 3, 5, 17, and 9.

To calculate the number of 4-digit even numbers that can be formed with the given digits, we can use the formula n^r, where n is the number of digits and r is the number of digits in the number. In this case, n = 5 and r = 4, so we can calculate 5^4 = 625.

Since we are looking for even numbers, we must eliminate any numbers that end in an odd digit.  This means that we must eliminate the numbers with the digits 3 and 5 as the last digit. Therefore, 625 - (3*25) - (5*25) = 625 - 75 - 125 = 425.

Now we must eliminate any numbers that do not begin with an even digit. This means that we must eliminate the numbers with the digits 3 and 9 as the first digit. Therefore, 425 - (3*25) - (9*25) = 425 - 75 - 225 = 125. Therefore, there are 125 four-digit even numbers that can be formed with the given digits.
