Answer:
The score of the fourth test should be 82
Step-by-step explanation:
Let the score of the fourth test be x.
(3×90+x)/4=88
270+x=352
x=82
Answer:
Extrapolation
Step-by-step explanation:
Given the data:
Distance (mi): 2 2.5 3 3.5 4
Time (min): 23 28 34 34 40
Line of best fit for the data:
y = 8x + 8
Making use of the best fit equation to make prediction of time is an example of extrapolation. This is because our result will be based in the fact that further prediction of the time it takes for any predicted distance will follow the same trend. Hence, it is important to note that a best fit line or regression model uses extrapolation techniques to make predictions.
Hence,
For the above ; estimate for X =5 will be ;
y = 8(5) + 8
y = 40 + 8
y = 48 minutes
Write the decimal number as a fraction
(over 1)
3.1818 = 3.1818 / 1
Multiplying by 1 to eliminate 4 decimal places
we multiply top and bottom by 4 10's
Numerator (N)
N = 3.1818 × 10 × 10 × 10 × 10 = 31818
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 = 10000
N / D = 31818 / 10000
Simplifying your fraction
= 31818/10000
= 15909/5000
= 3 909/5000. Hope this helped!!!
There were an on-time departure for all 3 flights in 5 of the simulations.
Answer:
n=14/5
Step-by-step explanation:
4n+n-16=-2
We move all terms to the left:
4n+n-16-(-2)=0
We add all the numbers together, and all the variables
5n-14=0
We move all terms containing n to the left, all other terms to the right
5n=14
n=14/5
