1. Here are two circles. Their centers are A and F A. What is the same about the two circles? What is different?

b. What is the length of segment AD? How do you know?

C. On the first circle, what segment is a diameter? How long is it?

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

is that 2 h and 25 min

step-by-step explanation:

if you take the square root of 3, the answer would be 1.732050808. to round the number, i use a saying to me. the saying is,

5 and up bump it up,

4 below keep it low.

this means that if you have the number 1.92534, then you could round to the nearest whole number, and that would be 2, because 9 is higher than 5, so you move the digit that is to the left by 1. 1+1=2.

if you have the number 1.27384, then you could round to the nearest whole number, and that would be 1, because 2 is less than 4, and so you would keep it low, you do not take it lower, you just keep it the same as it is.

if the distribution is symmetric, for example normal, and we know the mean is 74, then the probability of a junior has a score less than 74 is 0.5, or 50%.
