Answer:
58
Step-by-step explanation:
58 would increase the mean since it is much higher than the other numbers, making the data inaccurate
The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.
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
Thus, Suzi's elevation in the hike is 37 feet.
Answer:
A
Step-by-step explanation:
We know the y intercept is positive so that eliminates choice D.
y = 3x^2 -2x+1
This does not intercept the x axis
y = 3x^2 -6x+3
= 3(x^2 -2x+1)
3(x-1)^2
This intercepts the x axis at 1
This is not the equation for the graph
y = 3x^2 -7x+1
Let x = 1
y = 3-7+1
= -3
This will cross the x axis, so this cannot be the graph
