The solution of the given linear equation in one variable 5(3w - 2) -7= 23 is at w = 8/3.
According to the given question.
We have a linear equation in one variable 5(3w - 2) - 7 = 23.
As we know that, as we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the linear equation in one variable 5(3w -2) = 23 is given by
5(3w - 2) -7= 23
⇒ 15w - 10 -7 = 23 ( by distributive rule)
⇒ 15w -7-10 = 23
⇒ 15w -17 = 23
⇒ 15w = 23 + 17 ( adding 17 both the sides)
⇒ 15w = 40
⇒ w = 40/15
⇒ w = 8/3
Hence, the solution of the given linear equation in one variable 5(3w - 2) -7= 23 is at w = 8/3.

Determine whether each sequence is arithmetic. If so, identify the common difference. 97,86,75,64, ...........
The given sequence is arithmetic progression AP. The common difference is found to be (-11).
What is the sequence called arithmetic progression AP?Arithmetic Progression (AP) is a number sequence in which the difference between two numerical order is a constant value. Arithmetic Sequence is another name for it.
We would then come across some key terms in AP, that are denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)Some formula use in AP are-
The AP could also be expressed in concepts of common distinctions, as shown below; a, a + d, a + 2d, a + 3d, a + 4d, ………. ,a + (n – 1) dThe terms used in this progression for a given series are the first term, this same common difference, and the nth term. If a1, a2, a3,................, an is an AP, then the common difference " d " can be calculated as; d = a2 – a1 = a3 – a2 = ……. = an – an – 1.The formula for determining the n-th term of an AP is as follows: an = a + (n − 1) × dIf the first term, common difference, and total terms are known for an AP, the sum of the initial n terms can be calculated. The arithmetic progression sum formula is given below: Sn = n/2[2a + (n − 1) × d]Now as per the given question;
The given sequence is 97,86,75,64, ...........
Let the first term is'a₁' = 97.
Let 'a₂' = 86 is the second term.
Let the third term is 'a₃' = 75.
Let the fourth term be 'a₄' = 64.
As we know, in the AP, the difference between two consecutive terms is equal and therefore is referred to as the common difference.
d = a₂ - a₁
Substitute the values;
d = 86 - 97 = -11 ........(equation 1)
Now consider other pair;
d = a₃ - a₂
d = 75 - 86 = -11 .......(equation 2)
Put the values;
Thus, both the two equation are equal. It means the common difference is same that is (d = -11).
Therefore, the stated sequence is found to be in AP and the value of the common difference is found to be (d = -11).

Evaluate each expression for a=3 and b=-5 . 2 a+b
Evaluating the expression 2a + b for a = 3 and b = -5 is equal to -1.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.
Given the expression 2a + b, substitute the value of the variable a and the value of variable b.
2(3) + (-5)
Performing the arithmetic operations, we can have the value of the expression.
2(3) + (-5)
= 6 - 5
= 1
Hence, the expression 2a + b when a = 3 and b = -5 is equal to -1.

The standard deviation decreases as the sample size increases.
What is standard deviation?The degree of data dispersion from the mean is measured by the standard deviation. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
A region containing 68 percent of the total number of data points would be defined by one standard deviation, or one sigma, shown above or below the average value on that normal distribution curve. Ninety-five percent of the data would be covered by two sigmas above or below, whereas three sigmas would cover 99.7 percent.
The standard deviation is significant because it reveals the degree of dispersion of the values in a particular dataset. Every time we examine a dataset, we look for the following metrics: the dataset's geographic center.

Tickets for a school event were $1.75 for students and $3.75 for parents. If a total of 62tickets were sold for $178.50, how many student and parent tickets were sold? There were ____ student tickets sold and ____ parent tickets sold.
Answer:
There were 27 student tickets sold and 35 parent tickets sold.
Step-by-step explanation:
So first, we have to set up our equations!
s + p = 62 (s is the # of student tickets sold; p is the # of parent tickets sold; 62 is the total # of tickets sold)
1.75s + 3.75p = 178.50 (1.75s is the price for student tickets multiplied by the number of student tickets; 3.75p is the price for parent tickets multiplied by the number of parent tickets; 178.50 is the total amount of money)
Now! We are going to use elimination to solve for the variables, first for "s". To do this, we are going to multiply the first equation by -3.75!
-3.75 (s + p = 62)
-3.75s - 3.75 p = -232.50
+ 1.75s + 3.75p = 178.50
-2s = -54
s = 27
Next! We have to solve for "p" by multiplying the first equation by -1.75!
-1.75 (s + p = 62)
-1.75s - 1.75 p = -108.50
+ 1.75s + 3.75p = 178.50
2p = 70
p = 35
Lastly, we know that there were 27 student tickets sold, and 35 parent tickets sold.

Answer:
Step-by-step explanation:
Okay so this is fun, let's lable the angle just under 72, but still on the right side B. now, side b is corresponding or equal to (2y+48). So you set them to equal 180 because it makes a straight line....
(2y+48) + 72 = 180
2y + 48 + 72 = 180
2y + 120 = 180
2y = 180 - 120
2y = 60
y = 60/2
y = 30
plug this back in and ...
2(30)+48 =
(60+48) =
108
No we'll use 108 + 72 to make sure that the y is correct and....

The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.
Here, CF is a radius and the diameter is twice the radius.
Diameter of a circle = 2r
d = 2r
Where, r = 13
Diameter of a circle, d = 2r
Diameter of a circle = 2(13)
Diameter of a circle = 26
