Answer:

x =     7.48 (2d.p.)  or 7.5 (1 d.p.)

Step-by-step explanation:

Use Pythagoras' Theorem.

15 x 15 (or 15²) = 225

13 x 13 = 169

√<u>H - A </u>= O

225 - 169 = 56

√56 = 7.48 (2d.p.)  or 7.5 (1 d.p.)

Use substitution to solve the system of equations.<br> x-2y=1<br> 3x-6y=3
Ivahew [28]
Change first equation
x - 2y = 1
add 2y to both side
x = 2y + 1
Plug into second equation
3(2y+1) - 6y = 3
Distributive property
6y + 3 - 6y = 3
y = 0, plug into first equation
x - 2(0) = 1, x = 1
Solution: x = 1, y = 0

If you choose one student at random, what is the probability (±0.0001) that the student's score is between 20 and 30?
nordsb [41]
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
