9-16x^2
This is the answer pretty much the 3 is okay but once you see the four notice there’s - and + you’d multiply it
Answer:
A. 288.62
Step-by-step explanation:
Area of two triangles = 15.3 * 10.4 = 159.12
Area rectangle = hypotenuse triangle * 7
hypotenuse = √108.16 + 234.09
Hypotenuse = 18.5
Area rectangle = 18.5 * 7 = 129.5
129.5 + 159.12 = 288.62
Answer = A. 288.62

Answer:
Last option
Step-by-step explanation:
If we extract a sample of size n from a normal population and we want to estimate the population mean then the confidence interval for the mean will be:
Where
Where is an estimator for the mean μ.
n is the sample size and s is its standard deviation.
is the level of significance
= 1-Confidence Level
Then 
Then the 99% confidence interval for the population mean is
Do your best remember volume is H+L+W and area is L*W
Answer:
- Lisa: 22
- Chau: 14
- Austin: 88
Step-by-step explanation:
The given relations can be used to describe each of the numbers in terms of how many Lisa served. Those can then be related by the total served.
__
<h3>setup</h3>
Let L represent the number of orders Lisa served. Chau served 8 fewer, so (L -8). Austin served 4 times as many, so (4L). The total served was ...
L +(L -8) +4L = 124
<h3>solution</h3>
6L = 132 . . . . . . . . add 8, combine terms
L = 22 . . . . . . . . divide by 6
L -8 = 22 -8 = 14 . . . the number Chau served
4L = 4(22) = 88 . . . the number Austin served
The numbers each served were ...
- Lisa: 22
- Chau: 14
- Austin: 88
