Answer:
(0.4958, 0.7422)
Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is 
. The estimated standard deviation is given by 
. Because we have a large sample, the 90% confidence interval for p is given by 
where 
is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is 
, i.e., (0.4958, 0.7422).
To make 90 tortillas, he needs to make 6 batches. 6*15=90
2 cups masa per batch ->. 2 * 6=12 cups Masa
1.5 water per batch -> 1.5. * 6= 9 cups water
In order to figure this out you need to use slope intercept for for each of these hills. Let's say the first hill is HA and the second hill is B
slope intercept: y = mx + b
HA: y = (2/10)x
HB: y = (2/15)x
As you can see when you plot this on a graph, HB is steeper because the line rises more sharply.
Answer:
Step-by-step explanation:
A destroyed angle is called to as a rect-angle.
It's a pun on the "wreck"tangle
