Answer:
a = 12
Step-by-step explanation:
Formula for calculating the slope of a line is expressed as;
m = ∆y/∆x
m = y2-y1/x2-x1
Given
m = 1/2
x1 = a
y1 = 14
x2 = 8
y2 = a
Required.
Value of a
Substitute the given parameters into the formula
1/2 = a-14/8-a
Cross multiply
1(8-a) = 2(a-14)
8-a = 2a-28
Collect like terms
-a-2a = -28-8
-3a = -36
a = -36/-3
a = 12
Hence the value of a is 12
I think that they are correct
The length of the actual car is 240 inches
1/25 = 9.6/x
25x9.6/1=240
x=240 inches
Hope this helped you! :D
Answer:
Volume = 684 in^3
Step-by-step explanation:
To start, the equation for Volume = L*W*H
So, lets begin with the cube on the top, all of its sides are 6 inches in length, so do:
6*6*6 to get the volume of just it
216
Next. lets get the rectangular prism.
6*6*13
468
Last, combine these.
684 in^3
Answer:
Explained below.
Step-by-step explanation:
A graph is formed using the height of students in Diego's math class.
It is provided that he arranges the students from shortest to tallest and measures the height in inches of each student in the class.
A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution and the graph has a longer tail towards the right.
For a positively skewed data: Mean > Median
A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution and the graph has a longer tail towards the left.
For a negatively skewed data: Mean < Median
A distribution is said to be symmetric, if maximum of the data are collected in the middle of the distribution and the graph has equal proportion of tails on both sides.
For a symmetric data: Mean = Median
