The fraction of the basketball team that are 6.14 feet is 2/5 of the 45 members

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

The number of members that are six feet tall or taller is 45

The number of members that 6.14 feet tall or taller is 18.

From the member of 6 feet tall or taller, the fraction of member that are 6.14 feet tall or taller is 18/45 = 6/15 = 2/5.

therefore 2/5 of the 6 ft tall or taller members are 6.14 feet tall or taller.

The solution to the arithmetic progression is A = 94,188

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the sum of the arithmetic sequence be represented as A

Now , the value of A is

Let the zeroth term of the series be a₀

when i = 0

∑i=0 ( 2i - 312 ) = 2 ( 0 ) - 312

a₀ = -312

Let the first term of the series be a₁

when i = 1

∑i=1 ( 2i - 312 ) = 2 ( 1 ) - 312

a₁ = 310

So , the common difference d of the series = first term - zeroth term = 2

The value of d = 2

The number of terms n = 500

Sum of n terms of the arithmetic sequence is

Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Substituting the values in the equation , we get

A = a₀ + ( 500/2 ) [ 2 ( -310 ) + ( 500 - 1 ) ( 2 ) ]

On simplifying the equation , we get

A = -312 + ( 250 ) [ ( -620 ) + 499 ( 2 ) ]

A = -312 + ( 250 ) [ ( -620 ) + ( 998 ) ]

A = -312 + ( 250 ) [ 378 ]

A = -312 + 94,500

A = 94,188

Hence , the sum of the arithmetic sequence is 94,188

Step-by-step explanation: In many companies, especially small and medium, where there is a strive to establish any work process, it has been observed that testers are a little puzzled about how to start, progress and finish their testing job in a hurried manner.

The project or test manager always pressurize the test team to complete testing as soon as possible. With this pressure, somebody starts with a great methodical way but cannot complete the testing; somebody tries to be fast by short-cutting it, but cannot achieve quality. So, there is a problem in daily practice.

The numeric value of the expression in this problem is given as follows:

44.2.

The expression for this problem is defined as follows:

[tex]\pi \left(\frac{1}{\sqrt{2} - 1}\right)^2(\sqrt{2}+1)[/tex]

The first step is applying the square, which has higher precedence over multiplication.

For the square of a fraction, the square is applied to both the numerator and the denominator, and then the numerator is divided by the denominator, as follows:

[tex]\left(\frac{1}{\sqrt{2} - 1}\right)^2 = \frac{1^2}{(\sqrt{2}-1)^2} = \frac{1}{0.1716} = 5.83[/tex]

Then we have a multiplication of three terms, and the associative property states that the order of the factors do not change the product, hence:

π x 5.83 x (square root(2) + 1) = 44.2.

Which is the numeric value for the expression presented in this problem.

Predicting when Old Faithful will spurt next can be done by timing the previous eruption. the next eruption is expected to occur at 12:59. p.m

Generally, The eruption that begins at 11:32 a.m. will end at 11:36 a.m.

So, the next eruption will occur approximately 12.5t + 33 minutes after 11:36 a.m., which is 12.5 * 4 + 33 minutes after 11:36 a.m., or 83 minutes after 11:36 a.m.

Therefore, the next eruption is expected to occur at 12:59. p.m. (11:36 a.m. + 57 minutes).

To calculate this, you would first add the minutes (83) to the number of minutes in the starting time (36). This sum, 119, is greater than 60, so you need to carry over 1 hour from the minutes to the hours.

This leaves 19 minutes, which is less than 60, so the result is 12:19. However, you also need to add 1 hour to the starting time to account for the carried over hour, giving you a final result of 12:59.

The number of children in the group based on the information is 13.

Total number of cookies Abby baked = 124

Number of cookies remaining after children left the kitchen = 7

Number of cookies taken by the group of children = 124 - 7 = 117

Given that 117 cookies were equally shared by the children.

Let the number of children be x.

Number of children was more than 10 and less than 30

10 < x < 30

x will always be an integer.

Let a number of cookies each child took be c.

The prime factorization of 117 is 3*3*13.

As 117 = x * c

117, when written as the product of 2 numbers, that is x*c form, will be as given below:

1*117, 3*39, 9*13, 13*9, 39*3, 117*1

A distance is defined as an object's total movement without regard for direction. Distance is also defined as the amount of ground travelled by an object from its starting point to its final destination.

A distance can also be thought of as a scalar quantity, which means that the distance travelled by an object is independent of its motion direction. It is the entire path taken by an object. To calculate distance, we can use the formula below:

The percentage is defined as a ratio expressed as a fraction of 100.

To change a mixed fraction to a percent, you first need to convert the fractional part (in this case, 5/8) to a decimal. To do this, divide the numerator (5) by the denominator (8). In this case, 5/8 simplifies to 0.625.

Next, add the whole number (6) to the decimal from step 1 (0.625) to get 6.625.

Finally, multiply this sum by 100 and add the percent sign %, so 6.625 * 100 = 662.5%

Let,

These equations are valid because segment AP bisects the angle CAB, i.e. it splits it into two equal pieces. Similarly, segment BP bisects angle ABC.

Then we can say,

Let's focus on triangle CAB. The three interior angles add to 180 degrees. This is true of any triangle.

(angleCAB)+(angleCBA)+(angleACB) = 180

(2x) + (2y) + (44) = 180

2x+2y+44 = 180

2(x+y+22) = 180

x+y+22 = 180/2

x+y+22 = 90

x+y = 90-22

x+y = 68

Normally we would try to isolate one variable, but I'll stop here. We'll use this later in the next section.

--------------------

Now focus your attention on triangle PAB.

The three interior angles add to 180.

(anglePAB)+(angleABP)+(angleAPB) = 180

(x)+(y)+(z) = 180

x+y+z = 180

(x+y)+z = 180

68+z = 180 .... replace "x+y" with 68

z = 180-68

z = 112 degrees is the measure of angle APB.

Based on the function, an equivalent form of the function f above in which the minimum value of f appears as a constant or coefficient is f(x) = (x+1)^2 -25. (Option D)

The function is f(x) = (x + 6)(x – 4). Solving the function

f(x) = (x + 6)(x – 4)

= x (x – 4) + 6(x – 4)

= x^2 – 4x + 6x – 24

= x^2 + 2x – 24

= x^2 + 2x + 1– 25

= (x + 1)^2 – 25

When x = -1, the value of f(x) = (-1 + 1)^2 – 25 = -25
