What is under root?
The positive number, when multiplied by itself, represents the square of the number.
Under the root of any number gives a number by which if we multiply by the same number then it will give us the same number.
For example √4 =2
If we multiply 2×2 then it gives us 4.
√x is also written as [tex]x^{1/2}[/tex]
So,
[tex]18^{1/2}[/tex] ≡ √18 o will be the correct term in the radical expression.

A) 10
B) 12
C) 14
D) 16
Answer:
16
Step-by-step explanation:
The correct answer is option D which is the coordinate will be 16.
What is the midpoint?The mid point of the line is defined as the center point of any line it means that the distance of this point is same from the one end and to the other end.
Given that:-
The midpoint between two points is (-16 12). of one endpoint is (-24 8) then the other is (-8,The formula for calculating the midpoint of the line for the y coordinate will be:-
Ym= ( y1 + y2 ) / 2
12 = ( 8 + y2) / 2
24 = 8 + y2
y2 = 24 - 8
y2 = 16
Therefore the correct answer is option D which is the coordinate will be 16.

The correct option regarding the standard deviation of the residuals is given by:
The point will increase the standard deviation of the residuals because it has a large negative residual.
What are the mean and the standard deviation of a data-set?The mean of a data-set is given by the sum of all values in the data-set, divided by the number of values.The standard deviation of a data-set is given by the square root of the sum of the differences squared between each observation and the mean, divided by the number of values.Considering a scatter plot and a line of best fit, a residual is the difference between the observed value(scatter plot) and the predicted value(line of best fit).
Hence, the circled value has a large negative residual. For the standard deviation, the differences are squared, hence the circled value increasing the standard deviation, and the correct option is:
The point will increase the standard deviation of the residuals because it has a large negative residual.

Richard took his driving test to get his license. Out of a 40-question test, he got 36
correct. What percent did Richard get incorrect?
Answer:
Richard got a 90% score on his quiz! Therefore, he got 10% of the questions incorrect.
Step-by-step explanation:
The method I used to find this answer was simply taking the amount he had gotten, 36, and dividing it by the initial amount of questions- 40. From there, I got 0.9, which is the equivalent of 90%. 100% minus 90% is 10%, so he got 10% incorrect. Sorry for the mishap, I didn't pick up that it was meant to be the amount incorrect. :)
Answer:
100 divide by 40 you get 2.5 multiply by 4 you should get 10 percent

Jennifer invests $7,000 in an account for 12 years that pays compound interest
annually. She uses the expression P(1 + r) to find the total value of the account.
What will be the total value of the account after 12 years if the interest rate is 1.6%?
Answer:
The rule is P(1+r%) power of time (T) so you're gonna apply the number to the rule
Step-by-step explanation:
P=7000
r=1.6%
T=12
7000 x (1+r%) power of T
(1+1.6%) power of 12 = 1.20983040
so when we calculate 7000 x (1+1.6%) power of 12
the answer will be = 8468.812846
