Assuming there is no specific percentages in the grade book, you would need a grade of 95 to get your whole grade to 90. You find this out by working backwards starting with 90 to find average. You take 90 times 2 which equals 180 and you subtract 85 from that to get 95! Brainliest?
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x−4)=−3
(3)(x)+(3)(−4)=−3(Distribute)
3x+−12=−3
3x−12=−3
Step 2: Add 12 to both sides.
3x−12+12=−3+12
3x=9
Step 3: Divide both sides by 3.
3x
3
=
9
3
x=3

224/16= 14 (this is division)
Let
be the random variable representing the number of genes that do get mutated. Here
denotes a binomial distribution with parameters
(total number of genes) and
(probability of mutation).
Then the probability that *at most* 4 genes get mutated is
where
You should find that

Answer: 8</h3>
Reason:
Replace p with 2 and evaluate.
Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.
