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

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.

It's reflected over the y-axis, so it goes to the right side.
Answer:
a (4,-1)
Step-by-step explanation:
A is the answer.
Quadrilateral ABCD has vertices A ( 5,0) , B ( 3,6) , C (-3,6) , and D( -4, -5) . If ABCD is reflected in ×-axis, and then rotated by 90 degrees clockwise about origin to get a new quadrilateral A'B'C'D' , what is the distance between B' to C'. Enter the distance here
The final coordinates of B' and C' after the rotation are B''(6, -3) and C''(6, 3) while the distance between both points is; 6
Distance between B" and C" is;
B"C" = √[(6 - 6)² +(3 + 3)²]
B"C" = 6
What is the distance between coordinates?We are given coordinates of vertices of Quadrilateral ABCD as;
A ( 5,0) , B ( 3,6) , C (-3,6) , and D( -4, -5)
Reflection about the x-axis gives; B (3, 6) , C(-3, 6)
Now, the transformation rule for rotating 90 degrees clockwise is;
(x, y) becomes (y, -x)
Thus, coordinates B' and C' are now;
B''(6, -3) and C''(6, 3)
Distance between B" and C" is;
B"C" = √[(6 - 6)² +(3 + 3)²]
B"C" = 6

A gallon of paint can cover 50 square feet. Find how many gallon containers of paint should be bought to paint 3 coats
on each wall of a rectangular room with dimensions 10 feet by 18 feet and walls that are 8-feet tall.
Answer:
27 gallons
Step-by-step explanation:
A rectangular room is a rectangular prism. The floor and ceiling are the bases. The walls are the lateral faces. The lateral are of a rectangular prism is the product of the perimeter of the base and the height of the prism.
lateral area = Ph
lateral area = 2(10 ft + 18 ft) × 8 ft
lateral area = 448 ft²
area of walls = 448 ft²
area of three coats = 3 × 448 ft² = 1,344 ft²
area covered by 1 gallon of paint = 50 ft²
number of gallons of paint needed = 1344 ft² / 50 ft² = 26.88

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.
