Answer:
"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.
Step-by-step explanation:
The actual probability of the given scenario will be:
⇒ 
⇒ 
⇒ 
On solving the power, we get
⇒ 
Now on multiplying the above value in 100, we get
⇒ 
%
Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.
Let's define variables:
x = Rate in $ / hr of the mechanic working 15hr
y = Rate in $ / hr of the mechanic working 5hr
We have the following system of equations:
x + y = 130
15x + 5y = 1400
Solving the system we have:
x = $ 75 / hr
y = $ 55 / hr
Answer:
the rate charged per hour by mechanics was:
x = $ 75 / hr
y = $ 55 / hr
Answer:
1. (x-3)(x+2)
2. (x-5)(x-3)
3. x= 2,1
4. x= -2,-4
5. x= 3,-7
6. x= 1,-8
7. x= 5,-7
8. x= -1/3,-2
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
Consider ΔKLJ:
sinθ=opposite/hypotenuse
sin30=LJ/8√2
LJ=0.5*8√2=4√2
Consider ΔMLJ:
sinθ=opp/hyp
sin45=x/4√2
1/√2=x/4√2
4√2/√2=x
x=4
