Answer:
x = 33
y = 41
Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41
hope this was helpful.
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
The value of function on x=1 is 0.5
Step-by-step explanation:
In order to find the value of a function on given input, the input is put at the place of variable in the function.
Given function is:
We have to find the value of function on x = 1
Putting x = 1 in function
Hence,
The value of function on x=1 is 0.5

Answer: the answer is b
Step-by-step explanation:
Answer:
The possible X values are the natural numbers.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
Step-by-step explanation:
Since we are going to observe the cars and the experiment will end when one of them turns left, and X is the number of cars observed, the possible X values will be the natural numbers (1,2,3....). Clearly we can observe any number of cars before one of them turns left. We cannot observe negative numbers of cars, or zero cars (We are going to observe at least one car), or fractions of cars.
Given the outcomes below, find their associated X values:
For this part of the problem, we are going to count how many cars we observed in total and that will be the X value.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
