Answer:
y=1/3x + 2
Step-by-step explanation:
To write the equation of the line use y=mx+b where m is the slope and b is the y-intercept. Find the slope of the line, count the units between them vertically and then horizontally.
The point on the left is (-3, 1). Count up 2 units to 3. Then count from -3 over to the right 6 units to 3. The second point is (3,3). Thus the slope is 2/6 which simplifies to 1/3.
To find the y-intercept, find where the line crosses the y-axis which is (0,2) so b =2.
Now write in y=mx +b as y=1/3 x +2
I f you divide 350 by 2 you get 175. Then take 175 and multiply it by 6 you get 1,050 liters.
Answer:
Option D.
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
or
The y-intercept is the value of the function (output) when the value of x=0
In this problem
The output of the function P for x=0 is equal to 5
The output of the function Q for x=0 is equal to 4
therefore
The functions will have different outputs when x=0
Answer:
c) 50
Step-by-step explanation:
We have been given that the mean life of a particular brand of light bulb is 1200 hours. About 95% of this brand of bulbs will last between 1100 and 1300 hours.
We will use z-score formula to solve our given problem.
, where,
,
,
,
We know that 95% of data points lies within two standard deviation of mean, so 1100 will correspond to a z-score of -2 and 1300 will correspond to a z-score of 2.
We can use sample score 1300 and get same answer as:
Therefore, the standard deviation of the light bulbs’ life is 50 years.
This is honestly simple but we all need help! The answer is 55,053. Hope this helps! =3
