Answer:
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2.
15^2+ b^2=25^2
225+b^2= 625
b^2=400
b= 20 or x=20
Answer:
B
Step-by-step explanation:
The pattern is to add 4 each time. So 17+4 is 21, 21+4 is 25, and 25+4 is 29
First problem:
Find the z score for raw score 6 minutes:
6 - 5
z = --------- = 1.429
0.7
Using a TI-83 calculator's distribution functions, I found that the area to the right of 6 minutes is
normalcdf(1.428,100) = 0.076
125/1 + 7/1
=(( 125 x 1)) + ((7 x 1)) / 1 x 1
=(125 + 1 ) / 1
=132 / 1
=132 / 1
So, your answer is 132
Answer:
Correct choice is A
Step-by-step explanation:
The line divides the coordinate plane into two semiplanes (top and bottom).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality Actually, this region is top semiplane (red region).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality This region is exactly bottom semiplane (blue region).
These two semiplanes intersect by line
All another options contain some inequalities that do not include the line
