Answer:
68%.
Step-by-step explanation:
Dalvin's finishing time is normally distributed with a mean of 65 seconds and a standard deviation of 1 second.
Under the empirical rule, 68% of the results will be within 1 standard deviation.
Since the standard deviation is 1 second, 68% of Dalvin's finishing time will be between 64 and 66 seconds.

Solve the system using elimanation: 3x + 5y = -2 and -x + 2y = 8
Answer:
Step-by-step explanation:
3x+5y+3(-x+2y)=-2+3(8)
3x+5y-3x+6y=-2+24
11y=22
y=2, using this y in -x+2y=8 gives you
-x+2(2)=8
-x+4=8
-x=4
x=-4
So the solution is the point (x, y)=(-4, 2)
Maya is solving the equation 2(1+7x)=72. She lists an explanation for each step as shown. Which is the missing explanation for Maya's first step after writing the given equation?
Answer:
x = 5
Step-by-step explanation:
The given equation is :
2(1+7x)=72
Use the distributive property to the LHS.
2(1)+2(7x) = 72
2+14x = 72
Subtract 2 from both sides.
2+14x-2 = 72-2
14x = 70
x = 70/14
x = 5
So, the answer of the given equation is x = 5.

Find the area of the following figure and choose the appropriate result.
Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
We have a figure consist of Square and Triangle.
So, Area of Figure
= Area of Square + Area of Triangle
= 11.1 x 11.1 + 1/2 x 11.1 x 11.4
= 123.21 + 11.1 x 5.7
= 186.48 square cm

True or False: An asymptote is a line in which a graph gets close to but never crosses.
True
False
Answer:
True
Step-by-step explanation:
An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.
The statement is true.
What is an asymptote?Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.
An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.
Hence, the statement is true.
