Answer:
Domain (-∞, ∞)
Range (-∞, ∞)
Step-by-step explanation:
y = 1/4x - 6
The domain is all possible values for x.
The range is all possible values for y.
Picture the graph of this function: are there any discontinuities, like asymptotes or holes? If this answer is no (which it is), then the domain and range are unbounded and go from negative infinity to infinity.
61 is 115% of 53.04, because 61 divided by 1.15( Which is the same as 115%) equals 53.04.
Short answer : x = -13/3
But let's solve your equation step-by-step.
-2(x+8)=4x+10
Step 1: Simplify both sides of the equation.
(Distribute)
Step 2: Subtract 4x from both sides
Step 3: Add 16 to both sides.
Step 4: Divide both sides by -6.
Answer:
x = -13/3
Answer:
14.6% probability that a randomly chosen person will test positive
Step-by-step explanation:
We have these following probabilities:
10% probability that a randomly selected person has the disease.
If a person has the disease, 92% probability of testing positive.
100-10 = 90% probability that a person does not have the disease.
If a person does not have the disease, 100-94 = 6% probability of testing positive.
What is the probability that a randomly chosen person will test positive
92% of 10% or 6% of 90%.
Then
p = 0.92*0.1 + 0.06*0.9 = 0.146
14.6% probability that a randomly chosen person will test positive
