Which expressions are equivalent to (d^1/8)^5
Using exponent properties we can get two equivalent expressions:
⁸√d^5
d^(5/8)
Which expressions are equivalent to (d^1/8)^5?Here we need to use two properties, these are:
ⁿ√x = x^(1/n)
(x^n)^m = x^(n*m)
Now, if we use the first property, we can rewrite the expression as:
(d^1/8)^5 = ⁸√d^5
Which is an equivalent expression.
If we use the other property we can get:
(d^1/8)^5 = d^( (1/8)*5) = d^(5/8)
Which is another equivalent expression.

Yes , Are collinearity and betweenness of points maintained under rotation.
A rotation is a transformation that maintains congruence of the original figure and its image.
What does "collinearity" mean?
Collinearity is the statistical term for the correlation of predictor variables (or independent variables) in a regression model to represent a linear connection. They are unable to independently estimate the value of the dependent variable when predictor variables in the same regression model are coupled.What is an example of collinearity?

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).

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.

do i set them equal to each other since they are opposite from one another? or do i set it equal to 180? Can someone help? thanks !
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....
108 + 72 = 180 so.. CORRECT! :)

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.
Hope this Helps! :)
