Answer:
New mean will be 12
And no change in standard deviation
Step-by-step explanation:
We know the relationship between the two mean and standard deviation
If we add 2 to each value of x that means the mean will become n will become 2n and since we are adding 2 to each value
The new mean will become 12
And there will be no change in the standard deviation because of equal change in the each data.
Answer:
168 miles
Step-by-step explanation:
Law of sines,. a/sinA = b/sinB = c/sinC
25/sin44 = c/sin88. Angle C is 88° because the three angles of any triangle add to 180°
now a little Algebra gives us that
25(sin88)/sin44 =35.966 so B is our answer
Answer:
this equation cannot be written in slope-intercept form
Step-by-step explanation:
The given equation is equivalent to ...
2x +9 = 0 . . . . . subtract 1x
x + 4.5 = 0 . . . . divide by 2
x = -4.5 . . . . . . . the equation of a vertical line.
It has no y-intercept and its slope is undefined.
