The circumference of a circle is calculated using the following equation:
Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).
We know that the diameter of the circle given (also known as AB) is equal to 20 cm.
We can then plug this into the equation and solve for the circumference:
Since the question asks for the answer to be in terms of
, this is as far as we need to go. So
the circumference of the circle is: 
or D.
Answer:
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Step-by-step explanation:
We have given a table. According to that table a survey about the amount of time students spend doing homework each week has been conducted. The students were either in college or in high school. Now which of the choices below best describes how to measure the spread of this data.
The correct option is: The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Step-by-step explanation:
Find equation
y - y1 = m(x - x1)
y + 9 = -5(x - 2)
y = -5x + 10 - 9
y = -5x + 1 → Equaton
Answer:
$2.25
Step-by-step explanation:
Let "b" be the price of 1 brownie and "c" the price of 1 cookie.
At a bake sale, a student spent $11.00 buying 3 brownies and 5 cookies. Symbolicaly,
3 b + 5 c = 11.00 [1]
His friend spent $3.95 buying 1 brownie and 2 cookies. Symbolicaly,
1 b + 2 c = 3.95
b = 3.95 - 2c [2]
If we replace [2] in [1], we get
3 (3.95 - 2c) + 5 c = 11.00
11.85 - 6c + 5c = 11.00
c = 0.85
If we replace c = 0.85 in [2], we get
b = 3.95 - 2 (0.85) = 2.25
