Please help ! RT is the perpendicular bisector of SU. Find the value of n and SU.

Answers

Answer 1

Answer:

Answer:

The value of n is 5 and the length of side SU is 4 units.

Step-by-step explanation:

It is given that RT is the perpendicular bisector of SU.

It means RT bisects the line SU and T is the midpoint of SU.

Since T is the midpoint of SU, therefore the distance of T from S and U are same.

$ST=TU$

$4n-18=32-6n$

$4n+6n=32+18$

$10n=50$

Divide both sides by 10.

$n=5$

The value of n is 5.

$SU=ST+TU$

$SU=4n-18+32-6n$

$SU=-2n+14$

Put n=5,

$SU=-2(5)+14$

$SU=4$

The length of side SU is 4 units.

Answer 2

Answer:

Answer:

$n=5\text{ and }SU=4\text{ units}$

Step-by-step explanation:

Given information: RT is the perpendicular bisector of SU, ST=4n-18 and TU=32-6n.

It is given that RT is the perpendicular bisector of SU. It means RT divides SU in two equal parts at T.

$ST=TU$

Substitute the given values.

$4n-18=32-6n$

$4n+6n=32+18$

$10n=50$

Divided both sides by 10.

$n=5$

The value of n is 5.

$ST=TU=32-6(n)=32-6(5)=32-30=2$

We need to find the measure of SU.

$SU=ST+TU$

$SU=2+2$

$SU=4$

Hence, the measure of SU is 4 units.

Final answer:

The adjusted multiple coefficient of determination accounts for the number of independent variables in the model.

Explanation:

The adjusted multiple coefficient of determination, also known as the adjusted R-squared, is a statistical measure used in regression analysis to assess the goodness-of-fit of a regression model. It takes into account the number of independent variables in the model and adjusts the coefficient of determination (R-squared) to account for the degrees of freedom.

The adjusted R-squared provides a more accurate measure of the model's predictive power by penalizing the inclusion of unnecessary variables that do not contribute significantly to the model's explanatory power. It helps to prevent overfitting and provides a more reliable estimate of the model's performance.

At the beach cleanup, Maya's group collected 14.8 pounds of trash on Saturday and 12.5 pounds on Sunday. Will's group collected the same total amount of trash as Maya's group but collected only 11.8 pounds on Saturday. How much trash did Will's group collect on Sunday? A. 3.0 pounds B. 12.5 pounds C. 15.5 pounds D. 27.3 pounds

Answers

C) 15.5 pounds

Maya's group: 14.8 + 12.5 = 27.3

Will's group: 11.8 + ___ = 27.3
27.3 - 11.8 = 15.5

A six-sided number cube with faces numbered 1, 2, 3, 4, 5, and 6 is rolled. Which events are mutually exclusive? A. rolling a 4, rolling a prime number

B. rolling a 3, rolling a prime number

C.rolling a 2, rolling an even number

D. rolling a 5, rolling an odd number

Answers

The answer is A.

Mutually exclusive means something that can't happen at the same time.

You can't roll a 4 and say you got a prime number. So A is your answer.

B is wrong because if you roll a 3, you are also rolling a prime number.

C is wrong because if you roll a 2, you are also rolling an even number.

D is wrong because if you roll a 5, you are also rolling an odd number.

Hey there I see you need help well I am here to do just that the answer is

A. because mutually exclusive events are not possible so you cant roll a 4 and have it be a prime number

hope this helps
