Answer: y=-4
Step-by-step explanation:
8(3)+5y=4
24+5y=4
subtract each side by 24
5y=-20
divide by 5
5 y=-4
Divide both sides by 5
e^x=3.152 take the natural log of both sides...
x=ln(3.152)
x≈1.148
Answer:
$320
Step-by-step explanation:
400*0.8(decimal form of 80%) = 320
If the price of the item drops by 60% then that means the new price is 40% of the original
new price = p*0.4
ex:
new price = $100*0.4= $40
new price= $75*0.4 = $30
The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
<h3>
What is Experimental Probability?</h3>
Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.
Here , Favorable Outcome = 19
Total outcomes = 20
Probability = Favorable Outcome/ Total Outcome
= 19 / 20
= 95%
Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
