F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38

A two-factor study with two levels of factor A and three levels of factor B uses a separate group of n = 5 participants in each

Mashcka [7]

Answer: There are 30 participants are needed for the entire study.

Step-by-step explanation:

Since we have given that

Number of levels of factor A = 2

Number of levels of factor B = 3

Number of participants in each treatment condition = 5

So, the number of participants are needed for the entire study is given by

$2\times 3\times 5\\\\=6\times 5\\\\=30$

Hence, there are 30 participants are needed for the entire study.

Suzi starts her hike at 200 feet below sea level. When she reaches the end of the hike, she is still below sea level at −163 fee

Phantasy [73]

Answer:

Suzi's elevation in the hike is 37 feet.

Step-by-step explanation:

We are given the following in the question:

Position of Suzi in the starting of hike = 200 feet below sea level

= -200 feet

The negative sign shows below sea level.

Position of Suzi in the end of hike = -163 feet

Change in elevation from the beginning of Suzi's hike to the end of the hike

= Position of Suzi in the end of hike - Position of Suzi in the starting of hike

$=-163 - (-200)\\=-163 + 200\\=37\text{ feet}$

Thus, Suzi's elevation in the hike is 37 feet.

At a movie theater, an adult ticket costs $10 and a child ticket costs $6. There were 350 people at a movie showing. The revenue

Wittaler [7]

X - number of the adults, y - number of children;
The system is:
10 x + 6 y = 3292
x + y = 350 => y = 350 - x
----------------------
10 x + 6 * ( 350 - x ) = 3292
10 x + 2100 - 6 x = 3292
4 x = 3292 - 2100
4 x = 1192
x = 1192 : 4
x = 298
y = 350 - 298
y = 52
Answer:
There were 598 adults and 52 children at the showing.
