Answer:
The probability that you will get 3 pictures right is 0,015625
Step-by-step explanation:
To get the probability, equally likely, of guessing the picture we use the following formula
P=# of possibilities that meet the condition / #of equally likely possibilities.
# of possibilities that meet the condition= 2
#of equally likely possibilities= 8
So every time you guees you have 2 possibilities from 8 , that give us a probability of 2/8 or 1/4
We suppose once you guess 1 card , the tester put back the card with the others.
Now, we must guess 3 pictures, that will be the multiplication of each probability.
P= 1/4 *1/4*1/4
P= 0,015625
Answer:
Your answer is the first point
A reflection across the x-axis and then a transformation of -6 and 1.
The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments
We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:
1. Set y = f(x)
y = 4x - 3/2
2. Exchange x and y
x = 4y - 3/2
3. Solve for y
4y = x + 3/2
y = (x +3/2)/4
4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4
5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)
Answer:
Pedro needs about 8 weeks to complete 30 assignments.
Converting feet to inches, 8*12=96 and 96*4=384. Next, 40*12=480. Since 384*x (if x represents the cost per inch of crown molding)=16*100=1600 cents due to that for every inch, we add x amount of money, we can find x to be 1600/384=800/192=400/96=200/48=100/24=50/12=25/6 by simply dividing both the numerator and denominator by 2 each time. Since we add x amount of money for every inch, and we have 480 inches, 480*x=480*25/6=2000 cents=2000/100=20 dollars is our answer
