Answer:
a. Yes
See explanation below.
Step-by-step explanation:
Assuming that if the question is if we can use the normal approximation for the true proportion.
For this case we have n = 40 and p = 0.3 (probability of success)
We need to check some conditions:
1) Random sample : This condition is satisfied since the problem says that she randomly select 40 records
2) 
3) 10% condition: the random sample is assumed to be less than 10% of the original population size (assumed)
The population proportion have the following distribution
So then as we can see the normal approximation for this case makes sense since we have all the 3 conditions satisfied so then the answer would be:
a. Yes
Given:
The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).
To find:
The vertices for 
.
Solution:
The rule represents refection of polygon QRST across the x-axis.
If a figure is reflected across the x-axis, then
Using this rule, we get
Therefore, the vertices for are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).

In this question, we will use slope intercept form that is y=mx +b, where m is the slope and b is the y intercept .
For the given question . x=1, y=-1 and slope , m = -5
We need to substitute these values in slope intercept form and solve for b, that is
-1=-5(1)+b
-1 = -5+b
Adding 5 to both sides
b =4
So we have slope, m =-5 and b=4
THerefore required equation is
y=-5x+4
Answer:
49 m³
Step-by-step explanation:
Volume used between August and November = 6287 - 6238
= 49 m³
