Question:
An hour before show time, only 155 people are seated for rockfest. According to the ticket sales, 95% of the people have yet to arrive. How many tickets were sold?
Answer:
3100 tickets
Step-by-step explanation:
Given
--- Yet to arrive
![Seated = 155](https://tex.z-dn.net/?f=Seated%20%3D%20155)
Required
Determine the total number of people
If 95% are yet to arrive, then 5% have arrived (i.e. 100% - 95%)
So, the total number of people is calculated as:
![5\% * x = 155](https://tex.z-dn.net/?f=5%5C%25%20%2A%20x%20%3D%20155)
Where x represents the total number of tickets
Make x the subject
![x = \frac{155}{5\%}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B155%7D%7B5%5C%25%7D)
![x = \frac{155}{0.05}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B155%7D%7B0.05%7D)
![x = 3100](https://tex.z-dn.net/?f=x%20%3D%203100)
37493 < x < 37503
it is even....so choices so far are : 37494, 37496, 37498, 37,500, 37,502
rounded to the nearest ten is less then the number....
37494 rounded to the nearest ten = 37490.....it is less then the mystery number
and 37502 rounded to the nearest tens = 37500...it is less then the mystery number
ur other choices, when rounded to the nearest ten are greater then or equal to the mystery number...so they dont work
so now we have 2 choices....37494 and 37502
rounded to the nearest thousand is greater then the mystery number....
37494 rounded to the nearest thousand = 37000...that less then...so this wont work
37502 rounded to the nearest thousand = 38000....thats greater then the mystery number....BINGO....ur answer is : 37502 <==
Answer:
3383 Kg per hectare
Step-by-step explanation:
Given that:
Intercept and slope for a given regression equation is :
Intercept = 473 ; slope = 5
The dependent variable / predicted variable = rice yield (y)
The independent variable / predictor variable = annual Rainfall (x)
The regression model can be written has :
General form of a regression equation / model:
y = mx + c ; m = slope ; c = intercept
y = 5x + 473
predicted rice yield if the annual rainfall is 582 mm
y = 5(582) + 473
y = 2910 + 473
y = 3383 Kg per hectare
Answer:
- Collect like terms and simplify
- Subtract 7 from both sides
