Answer:
Step-by-step explanation:
The given linear equation is
To solve for y, we first subtract 3x from both sides to obtain:
Divide through by 5
This simplifies to
Or
Answer:
Step-by-step explanation:
a. Y intercept is where the line crosses the y axis, so for l1 it’s (0,4). Answer is 4.
b. Y intercept for l2 is point (0,2). Answer is 2.
c. l1 gradient is -1/2. Rise/run
So l1 equation is y = -1/2x + 4
l2 gradient is 1.
Equation is y = x + 2
e. x+2= -1/2x + 4
1.5x = 2
x = 1.333...
y = plug into one of the equations value of x. So y = 3.333...
f. 1.33+ 2 = 3.33
-1/2 times 1.33 + 4 = 3.33 (rounded)
Consider : y² = 25
⇒ y = 
We know that : 5² = 25 and also (-5)² = 25
⇒ y = 
⇒ y = +5 or -5
So, The Answer is C
Step-by-step explanation:
what is Descriptive statistics?
Descriptive statistics involve the use of fundamental information from a dataset to make a summary, general, or overview report of the information from the given data. in descriptive statistics, results are collected from data directly without making direct inference
with descriptive statistics, you are simply describing what is or what the data shows
How important is descriptive statistics?
Descriptive statistics aids in the presentation of data in a precise, understandable manner, which allows a simpler interpretation of the data.
hence with descriptive statistics storytelling for data becomes very easy as we can visualize results and make reports through Descriptive statistic
