Answer:
0.8686 or 86.86 %
0.2148 or 21.48 %
Step-by-step explanation:
In z table the value of z > - 1,12 is 0.1314 (value from the z point to the left of the curve ) then 1 - 01314 will be value from z point to the right
Again from z table we get for z = - 0.79 the value 0.2148 s the vale from the point up to the left tail
The answer is 2. If you multiply the brackets out then you will get -40 over -20, and a negative divided by a negative is a positive therefore it is 2.
Answer:
x=3 y = 4
Step-by-step explanation:
3x+5y=29 .........*2 (multiply by2) = 6x+10y=58
2x+3y=18 *-3 = (multiply by -3)= -6x-9y = -54
ADD both(-6x cancels 6x) y= 4
2x+ 3y = 18 2x+ 12 = 18 2x = 6 x = 3
