42 inches squared
base times height divided by two
7x12 divided by two is 42
3y+15=4y-3
Subtract 3y from both sides
15=y-3
Add 3 to both sides
Y=18
4(18)-3
72-3
69 both angles are 69
Answer:
<h2> The fourth</h2>
Step-by-step explanation:
Vertex of f is (-1, -4) so its range is limited to y≥-4
|x+1| is always ≥0 therefore -|x+1| is always ≤0 {4 is insignificant to this - slope doesn't mean in range} so its range is limited to y≤0
Solution :
This is the two tailed test.
The null hypothesis and the alternate hypothesis is as :
Null hypothesis is 
Alternate hypothesis is 

Therefore, the critical value of z is :

Now the test statics is :



The test statics is 0.878
We see that it is a right tailed test.


= 0.3800
Thus , P-value > α
So we fail to reject the null hypothesis.
Volume = width x height x length
= 2.5 x 4.331 x 4.863
= 52.65 ft^3
