The value of the mean for the scores in an exam which are normally distributed is 70.

Given:

the scores in an exam were normally distributed with unknown mean and a standard deviation of 5 .

if 30.85 % of students scored more than 72.5 . what is the value of the mean = ?

Mean = µ

σ = 5

x = 72.5

The z score corresponding to the area 30.85% in the right tail is :

Zi score = Z 0.3085

             = 0.500

Again : Z₀ = x- µ/σ

           ⇒ x- µ = Z₀σ

           ⇒ µ = x - Z₀σ

                  = 72.5 - 0.500 × 5    (using z table)

                  = 72.5 - 2.5

                  = 70

Hence we get the unknown mean as 70.

The two points that represent the solution of the inequality graph are (-1,0) and (0,2).

The function of an inequality graph obeys the linear slope intercept form y= mx + b, but the distinction here is that the equal to sign (=) is represented with >, <, ≥, and ≤, as the case may be. So, we use, > and < when the line is dotted or dashed and  ≥, and ≤, when we have a solid line on the graph.

So, using the two points on the (-1,0) and (0,2), the slope of the graph is 2, and the y-intercept is also 2.

The linear representation of the graph is: y = 2x + 2, in its inequality form, sInce the graph is increasing from the left to the right and the line is solid; we have:

y  ≥ 2x + 2

Therefore, we can conclude that the function of the graph is y  ≥ 2x + 2 and the two points that represent the solution of the inequality graph are (-1,0) and (0,2).

Answer:

100 beats per minute

Step-by-step explanation:

If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.

To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:

28.8 secs = 48 beats

60 secs = x beats

Cross multiply

28.8*x = 60*48

28.8x = 2,880

Divide both sides by 28.8

x = 2,880/28.8

x = 100

✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM

37.5% of the area between 550 and 725 on a standardized test of educational achievement lies within one standard deviation of the mean score of 600.

The area between 550 and 725 on a standardized test of educational achievement is equal to the percentage of students whose scores fall within one standard deviation (or 68%) of the mean score of 600. This can be expressed mathematically as:

Percentage = (725 - 550) / (2 * 50) = 37.5 / 100 = 37.5%

To explain in more detail, a standard deviation is a measure of the spread of a dataset around its mean value. The mean value in this case is 600, and the standard deviation is 50. Therefore, one standard deviation from the mean is calculated by subtracting or adding the standard deviation (50) from the mean (600), giving a range of 550 to 650.

Since the area in question spans across two standard deviations (550 to 725), the area is calculated by subtracting the lower range (550) from the upper range (725) and then dividing it by two standard deviations (100). This gives us the area, which is 37.5%.

To summarize, 37.5% of the area between 550 and 725 on a standardized test of educational achievement lies within one standard deviation of the mean score of 600.

Therefore, the answer is option B 23 and 4/7 inch² that is at least 23 and 4/7 inch² paper is needed to wrap 6 mini muffins.

Total surface area refers to the sum of the areas of all the faces or surfaces of a three-dimensional object. It includes the areas of the base, top, and lateral faces of the object. For example, the total surface area of a cube is the sum of the areas of all six faces, while the total surface area of a cylinder includes the areas of both circular bases and the lateral surface area.

Here,

The surface area of each mini muffin can be calculated by finding the lateral surface area of the cylinder and adding the surface area of its circular bases. The diameter of each mini muffin is 2 inches, so the radius is 1 inch. The height is 1 and 1/4 inches. The lateral surface area of each mini muffin is given by:

Lateral surface area = height x circumference

Lateral surface area = (5/4) x 2 x πr

Lateral surface area = (5/4) x 2 x (22/7) x 1

Lateral surface area = 11/2 cm²

The surface area of each circular base is given by:

Surface area of base = πr²

Surface area of base = (22/7) x 1²

Surface area of base = 22/7 cm²

The total surface area of each mini muffin is given by:

Total surface area = Lateral surface area + 2 x Surface area of base

Total surface area = (11/2) + 2 x (22/7)

Total surface area = 69/14 cm²

To wrap 6 mini muffins, we need to multiply the surface area of one mini muffin by 6. So the total surface area needed is:

Total surface area = 6 x (69/14)

Total surface area = 207/7 cm² (approx.)

Converting to square inches and simplifying, we get:

Total surface area = 23 and 4/7 inch²

The given integral is evaluated by using the substitution rule. Integrating by substitution means replacing a given function with another one that makes it simpler to integrate. By putting u = sin(t), and hence du = cos(t) dt, we can easily compute the integral.

The given integral is:
π/2 ∫0 cos (t) / √1+sin^2(t) dt
To evaluate this integral, we will use the substitution rule. Integrating by substitution means replacing a given function with another one that makes it simpler to integrate.
Put u = sin(t), and hence du = cos(t) dt. Then, the given integral becomes:
π/2 ∫0 cos (t) / √1+sin^2(t) dt
= π/2 ∫0 1 / √(1 - u²) du
This is the integral of the function 1 / √(1 - u²), which is a standard integral. We can evaluate it by using the trigonometric substitution u = sin(θ), du = cos(θ) dθ, and the identity sin²(θ) + cos²(θ) = 1.
Thus, we have:
π/2 ∫0 1 / √(1 - u²) du
= π/2 ∫0 cos(θ) / cos(θ) dθ     [using u = sin(θ) and cos(θ) = √(1 - sin²(θ))]
= π/2 ∫0 1 dθ
= π/2 [θ]0π/2

Step-by-step explanation:

Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

A fοrmula called an equatiοn uses the equals symbοl (=) tο denοte the equality οf twο expressiοns. An equal sign ("=") links twο expressiοns tοgether tο fοrm an equatiοn. The twο expressiοns οn either side οf the equals sign are referred tο as the "left-hand side" and "right-hand side" οf the equatiοn. The right side οf an equatiοn is typically assumed tο be zerο. As we can balance this by deducting the expressiοn οn the right frοm the expressiοns οn bοth sides, this wοn't reduce the generality. A statement is nοt an equatiοn if it has nο "equal tο" sign. That will be regarded as a phrase.

Parker's standardized score (z-score) of +2.5 means that he is 2.5 standard deviations above the average score for the class. C

Normal distribution, the mean (average) is represented by the letter μ and the standard deviation by σ.

The z-score is a measure of how many standard deviations a data point is away from the mean.

A positive z-score indicates that the data point is above the mean, while a negative z-score indicates that it is below the mean.
Parker's z-score of +2.5 tells us that his score is 2.5 standard deviations above the class average.

We don't know the exact values of μ and σ, but we can use the properties of the Normal distribution to make some general statements about Parker's score.
99% of the data in a Normal distribution falls within 3 standard deviations of the mean.

Since Parker's z-score is 2.5, we can estimate that his score is higher than about 99% of the scores in the class.

Parker is performing very well in the history class compared to his peers.
z-score is a standardized measure, which means that it can be used to compare scores from different distributions.

If we wanted to compare Parker's score to the scores of students in another class, we could convert both sets of scores to z-scores and compare them directly.
Parker's z-score of +2.5 means that he is performing exceptionally well in the history class, with a score that is 2.5 standard deviations above the class average.

Angles a and 139 are corresponding angles thus a = 139°

Angles a and b are supplementary hence b = 41°

When a transversal connects two parallel lines, it creates corresponding angles, which are two angles in a pair. A transversal produces a total of eight angles when it crosses two parallel lines. Pairs of these angles that are at the same relative position at each intersection are said to be corresponding angles.

Angles that correspond to one another have the same measure and are therefore congruent. The characteristics of parallel lines and the angles that the transversal forms lead to this congruence.
