Answer:
The second and fourth answer are correct
Step-by-step explanation:
Answer:
9 11/12
Step-by-step explanation:
1st step- convert the mixed number into improper fraction to convert it just multiply the denominator with the whole number and after you get the product, add the product with the numerator and then same with the other set of fraction
2nd step- multiply the numerator by numerator and denominator by denominator
3rd step- after you multiply it simplify it

The answer is -15 because -20 plus -10 is -15 and -30 plus 15 is -15
Answer:
-x³ + 5y + 3
Step-by-step explanation:
It helps to rewrite the given polynomial according to its degree (exponent), in <u>descending</u> order. Also, for variables without a coefficient, it helps to include "1" with it to make it less confusing when combining like terms.
- x³ + 3y + ( 1 )y + ( 1 )y + 5 + 2 - 4
One way to simplify a polynomial is to combine the like terms if there are any. Two or more terms in a polynomial are like terms if they have the same variable(s) with the same exponent.
- x³ is the only term with an exponent of 3, so we wouldn't have to combine it with other terms. We need to combine the terms with the variable "y," as they have the same degree of 1.
- x³ + 5y + 5 + 2 - 4
Lastly, combine the constants (5 + 2 - 4):
- x³ + 5y + 3

The tennis wall volley test has two 30-second trials, and a teacher is interested in analyzing the variation between them. The instructor will most likely determine the "intraclass correlation coefficient" statistic.
<h3>Explain the term intraclass correlation coefficient?</h3>
An indicator of the validity of the ratings for clusters is the intraclass correlation coefficient, abbreviated ICC.
- Data that is grouped together is referred to as a cluster. Instead than comparing two independent classes of data, ICC is used to detect correlations within a specific class of data.
- As was already noted, Pearson's r is the most often utilized correlation coefficient.
- When there are just one or two significant pairs from just one or two raters, Pearson's correlation coefficient is typically employed to measure inter-rater reliability.
- However, this intraclass correlation coefficient ought to be utilized if there are more pairs.
