Answer:
X>_1 and x<_7
Step-by-step explanation:
Let's solve for x.
Layout equation:
a/b
(2x−12)=c/d
Step 1: Multiply both sides by b.
2ax−12a=bc/d
Step 2: Multiply both sides by d.
2adx−12ad=bc
Step 3: Add 12ad to both sides.
2adx−12ad+12ad=bc+12ad
2adx=12ad+bc
Step 4: Divide both sides by 2ad.
2adx/2ad=12ad+bc/2ad
So the answer is x=12ad+bc/2ad.
Answer:
S(t) = 4.725t + 478.25
S(t) = 4.725(42)+478.25
S(t) = 676.7
Step-by-step explanation:
In the question, score is a function of time, that means time is the x-axis, while score is the y-axis.
Order the pairs to get:
(30,620) and (70, 809)
With these values, you use the the equation
to get the slope m.

Use this equation and input any ordered pair to get the final function.
y-y1 = m(x-x1)
y-620 = 4.725x-141.75
y = 4.725x + 478.25
Replace x with t and y with S(t) to fit the x & y axis of the question.

Answer:
Hence, the probability of an access code “1234”= 
Step-by-step explanation:
<em>" The probability of an event is defined as the ratio of total number of favourable outcomes to the total number of possible outcomes ".</em>
A bank requires a four-digit access code for each account. The access code is generated using the digits 0–9, and the digits can be repeated.
The total number of outcomes possible are 10×10×10×10=10000
since the first place any of the 10 digits are possible, similarly for the second, third and fourth place.
Also each code is a unique representation in itself.
Hence the code "1234" is unique.
Hence, the probability of an access code “1234”=
