Answer:
Volume of the sphere up to two decimal places= 
cubic yards
Surface area of the sphere up to two decimal places 
square yards
Step-by-step explanation:
Given:
The radius of the sphere= 1 yard
Volume of a Sphere:
:
cubic yards
Volume of the sphere up to two decimal places= cubic yards
Surface area of the sphere= 
Surface area of the sphere up to two decimal places square yards
Answer:
AB=14
Step-by-step explanation:
First you write the equation 2(2x-4)=28 because if b is the midpoint then AB is half of the line so you multiply that half by two the make it equal to the whole line.
Then you distribute the two and get 4x-8=28.
Then you add 8 to 28 and get 36.
Then you divide 36 by 4 because the 4 and x are being multiplied together so you have to divide to get them apart.
So then you get x=9 and you aren't done yet because you have to plug x into 2x-4.
So it is 2(9)-4 which is 18-4 which equals 14.
Answer:
I am so not good at math at all
Answer:
because everything is relative to each other.
Step-by-step explanation: Graphing ordered pairs is only the beginning of the story. Once you know how to place points on a grid, you can use them to make sense of all kinds of mathematical relationships. A linear relationship is a relationship between variables such that when plotted on a coordinate plane, the points lie on a line. Let’s start by looking at a series of points in Quadrant I on the coordinate plane. Look at the five ordered pairs (and their x– and y-coordinates) below.
The number of student more passed the retake, when the students need a 65 in order to pass the test is 8.
<h3>What is box and whiskers plot?</h3>
Box plot is the way of representation of data which gives the graphical image of the data set to understand better. In this the data is represented with the help of quartile.
- A.The difference in the median grade-
The median of first test is 60 while the second test is 80. Thus, the difference is,
- B. Compare the percent of students who got at least a 60 on the original test to those that got at least a 60 on the retake.
The student, who got at least 60 in first test, falls in the second half of the plot. Thus, the 50% of students got atleast 60% marks. In the retake test, all 100% student got at least 60 on test.
- C. If the students need a 65 in order to pass the test, how many more passed the retake?
In the first test 1/4 are passed while in second test 3/4 students are passed and got the marks 65 or more than this, Thus the number of student pass more in this test,
Thus, the number of student more passed the retake, when the students need a 65 in order to pass the test is 8.
