From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
Right angle because it has a 90° angle
Answer:
The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 67 - 4.54 = 62.46 ounches.
The upper end of the interval is the sample mean added to M. So it is 67 + 4.54 = 71.54 ounces.
The 95% confidence interval for the true population mean dog weight is between 62.46 ounces and 71.54 ounces.
Answer:
Ricky hits 1202 base
Pedro hits = 1485 base
Step-by-step explanation:
Pedro + Ricky = 2687 hits
Let Ricky hits = x
So the Pedro hits will be = x + 283
( x + 283 ) + x = 2687
2 x + 283 = 2687
2 x = 2687 - 283
2 x = 2404
x = 1202
So the Ricky hits 1202 base
Pedro hits (1202 + 283) = 1485 base
