Answer:
56.7
Step-by-step explanation:
Just Add all numbers
Answer:
70%
Step-by-step explanation:
The number of students with an April birthday and candles is in the upper left, 14. That’s the “part” Percentage is part/whole x 100.
To figure out the “whole”, you need to add up all the students in the first row of the table, because those are the April birthdays. 14 + 6 = 20
14/20 = 0.7 x 100 = 70%
Answer:
1/2, or 0.5
Step-by-step explanation:
There are 4 ways that 2 coins can fall...
Both heads (this satisfies our situation)
1st coin heads, 2nd coin tails
1st coin tails, 2nd coin heads
Both tails (this satisfies our situation)
We have 2 out of 4 ways to satisfy this situation, so our experimental probability is
P = 2/4 which reduces to
P = 1/2 , or 0.5 as a decimal
Let p be the prize of a pen and m the prize of a mechanical pencils. If you buy six pens and one mechanical pencil, you spend 6p+m. We know that this equals 9, because you get 1$ change from a 10$ bill.
Similarly, if you buy four pens and two mechanical pencils, you spend 4p+2m, which is 8$, because now you get a $2 change. Put these equation together in a system:
Now, if you multiply the first equation by 2, the system becomes
Subtract the second equation from the first:
Plug this value into the first equation to get
Answer:
According with the graph:
1.) The equation of the regresion line is: y=5,720.10391 x + 957.225810
2.) The values of the correlation coefficient is 0.86
Step-by-step explanation:
In the graph is shown:
1.) Line of Best Fit
y=5720.10391 x + 957.225810
2.) Correlation
.86
