As a result, 95% of the students had grade point averages ranging from 1.83 to 3.39.

A normal distribution is a data set design in which the majority of values cluster around the middle of the range and the remainder taper off symmetrically toward either end.

The normal distribution is also known as the bell curve because the probability density graph resembles a bell. It is also known as the Gaussian distribution, after German mathematician Carl Gauss, who described it initially.

A bell-curve distribution is a normal Distribution.

Let X be the grade point averages of undergraduate students at one university.

X ~ Normal Distribution(2.61,(0.39)2)

P(1.83 < X < 3.39)

= P(X < 3.39) - P(X < 1.83)

= P((X - μ)/σ < (3.39 - 2.61)/.39) - P(((X - μ)/σ)< (1.83 - 2.61)/039)

= P(z < 2) -P(z < -2)

= P(-2 < z < 2)

Thus, given a regular normal distribution (μ=0, σ =1), z is between 2 standard deviations away from the mean.

According to the Empirical Rule, 95% of the data obtained after a normal distribution is within two standard deviations of the mean.

The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.

The catering cost was determined if the cost per person is R 225,00.​

The cost per person = 225,00 R

To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.

Let us assume,

Suppose you can find the cost for 50 people.

Then,

We can write,

Catering cost = x

x = 225,00 * 50

x = 1,125,000 R

Therefore,

The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.

42 bologna sandwiches were made

The ratio is given as

Cheese : Bologna : Peanut butter = 5 : 7 : 8

Also, we have

Total = 120 sandwiches

The number of bologna sandwiches made is calculated using

Bologna = bologna ratio/total ratio * 120

So, we have

Bologna = 7/(5 + 7 + 8) * 120

Evaluate

Bologna = 42

Hence, 42 bologna sandwiches were made

a) A minimum of number of dogs that could have a mass of more than 24 kg is 6.

b) The maximum number of dogs that could have a mass of more than 18 kg is 20.

Rearrange the function using fundamental algebraic concepts to get the value of x when the derivative equals 0. This response gives the x-coordinate of the function's vertex, which is where the maximum or minimum will occur. To find the minimum or maximum, rewrite the solution into the original function.

70 acres will cost 434,000

Step-by-step explanation:

you’re buying 60 acres Of farmland at a cost of 372000

1) What is the cost per acre

In order to find the cost per acre we divide the values which is;

➟ 372000 ÷ 60

➟ 6200

∴ it will cost 6200 per acre

2) What would be the cost for 70 acres

to find how much it will cost for 70 acres we will multiply the value per acre by 70 which is;

➟ 6200 × 70

Let x = the one sibling

Let x + 1 = the second sibling

Let x + 2 = the third sibling

Let x+4 = the fourth sibling.

If you add the four siblings together they equal 86

(x) + (x +1) + (x + 2) + (x+3) = 86  I put the parentheses in so that you can see each sibling, but it is not needed.

x + x+ 1 +x + 2 + x+ 3 = 86  Combine like terms

4x + 6 = 86  Subtract 6 from both sides

4x = 80  Divide both sides by 4

x = 20

The first sibling is 20, then 21, then 22 and finally 23

Check:

20 + 21 + 22 + 23 = 86

The length of time that it cost less to move good across town will be more than 2.36 hours.

From the information, ACME movers charges $59 plus $20 per hour to move household goods across town and Hank movers charges $45 per hour.

Let the number of hours be represented by h.

Therefore, the appropriate equation will be:

59 + 20h = 45h

Collect like terms

45h - 20h = 59

25h = 59

h = 59/25

h = 2.36 hours.

Therefore, the length of time that it cost less to move good across town will be more than 2.36 hours.

During an isosceles triangle two angles are identical, adding up to a total of 180, and its x value is 78.

Isosceles triangle: what is it?

In geometry, an isosceles triangle is one with at least two sides of equal length. There are two ways to define it: either as having precisely two sides of equal length or at least two sides of equal length, with the equilateral triangle being an exception to the second definition.

The aforementioned claim states that a triangle's total number of angles is 180.

the total of all angles in a triangle is 180.

Answer:

B. The airplane starts its descent from an altitude 500 feet higher

Step-by-step explanation:

f(x) = −300x + 30,000

the function itself represents the airplane's altitude. the y intercept, 30,000 ft, then represents the initial starting position of the plane.

when it changes

g(x) = −300x + 30,500

only the y intercept changes. it's now 30,500 ft, which is 500 more than before. that means the plane initial position is 500 feet higher.

since the term with x doesn't change, the rate will not be affected. the answers with slower or faster talks about rate, which isn't what changed.

The line of reflection of the given congruent angles is the y-axis.

A line of reflection is defined as a line that lies in a position between two identical mirror images so that any point on one image is the same distance from the line as the same point on the other flipped image

Now, from the attached image, we see that the two given congruent triangles are; ΔAHJ and ΔADB

Now, we see that the coordinates are transformed as folllows;

D(5, 2) → H(-5, 2)

B(3, 0) → J(-3, 0)

Now, this type of transformation follows the transformation rule; (x, y) → (−x, y). This means it was reflected over the y-axis.

Answer:2

Step-by-step explanation:

It is true. For all rational numbers a and b, a−b = a + (−b).

Given that,
To determine whether the statement, "For all rational numbers a and b, a−b = a + (−b)." is true or false.

In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.

Here,
= a + (-b)
Since in the parenthesis there is a negative value, when we open the parenthesis the sign of the arithmetic operator will change accordingly,
So,
= a - b
So, the condition is true for all rational numbers.

Thus, It is true. For all rational numbers a and b, a−b = a + (−b).
