Answer:

True

Step-by-step explanation:

When sampling is done with replacement, then events are considered to be independent, meaning the result of the first pick will not change the probabilities for the second pick. Without replacement: When sampling is done without replacement, each member of a population may be chosen only once.

Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)

I Need Assistance.... Please Help<br>Thank You

Answer:

7. 37

8. 74

9. 402

10. 74

Step-by-step explanation:

You can simplify the expressions and then do the substitution of the variable value, or you can simply plug in the numbers and do the arithmetic. Either way takes about the same effort.

7. 3(5·4 -1) -4(3·4 -7) = 3·19 -4·5 = 57 -20 = 37

8. 3(5·4 -6) +4(20 -3·4) = 3·14 +4·8 = 74

9. 5(10r +3) -7r = 50r +15 -7r = 43r +15 = 43·9 +15 = 402

10. 4(5r -3) -2(6r -7) = 20r -12 -12r +14 = 8r +2 = 8·9 +2 = 74

Please help find “b” for me!
svp [43]

Answer:

12

Step-by-step explanation:

Pythagorean Theorem states that

a² + b² = c²

plug in your terms

9² + b² = 15²

81 + b² = 225

then subtract 81 from 225 to get your b²

b² = 144

then find the square root of 144

the square root is 12 because 12 x 12 = 144
